The Laser Safety Line Projector draws a bright, continuous red, green or blue laser line on the floor from an overhead mount, marking forklift lanes, pedestrian walkways, keep-clear zones and dock edges with nothing to tape, paint or repaint. It comes in 10W, 20W, 30W and 40W; line length is mounting height times the projection ratio, so a 30W or 40W unit (1:4) mounted 20 ft up draws an 80 ft line, and the 20–40W models adjust line width from 1 to 20 cm. It plugs into a standard 100–240V outlet, and a free clip-on lever attachment lets you set exactly where the line stops.
Paint wears off. Tape lifts. A projected line does neither.
The Laser Safety Line Projector casts a hard, continuous line of laser light along a floor from overhead — a walkway edge, a keep-clear zone, a dock boundary, an aisle divider. Nothing is bonded to the floor, so nothing gets scuffed away by forklift traffic, nothing needs re-taping after a deep clean, and moving the line means re-aiming a fixture rather than stripping and re-marking.
10W, 20W, 30W or 40W.
Our logo projectors size an image with lens number × distance. A laser line does not work that way. Line length = mounting height × the ratio for that wattage, and the ratio differs by tier — which is exactly the detail that gets missed when people plan a run.
Work the units out before you buy them: divide the length of the run by (mounting height × ratio), and round up. A 200 ft aisle at 20 ft mounting height on 30W units gives 80 ft per unit — three fixtures. On 20W units at the same height it is 60 ft per unit, so four. The wattage choice is a unit-count decision as much as a brightness one.
Maximum mounting height: 15 m (about 50 ft) on the 10W and 20W, and 20 m (about 65 ft) on the 30W and 40W — measured in a well-lit warehouse, so a dark space will go further. Note that height and width pull against each other: at around 10 m you can run the line at its widest, but by 15 m you should run it thin to keep it reading.
Color is tied to the wattage — you cannot have every color at every power.
One more difference worth knowing: the 20W, 30W and 40W all have an adjustable line width — only the 10W is fixed. All three adjust across the same 1 cm to 20 cm range, so what the extra wattage buys you is not more width, it is more brightness at the width you choose.
Choose the color carefully — it cannot be changed later. The laser color is set when the unit is built and there is no way to change it after purchase: no filter, no swap, no field conversion. Combined with the fact that color availability depends on wattage, that makes this the one decision to settle before you order. If a site standard fixes your color, tell us the color first and we will work back to the wattage.
Green reads brightest to the human eye at the same power, which is why it is the usual choice for a busy floor. Red is the convention for hazard and keep-out boundaries in a lot of plants, and blue is used to separate a pedestrian route from a vehicle route at a glance. If you need a specific color for an existing site standard, that decision drives the wattage — tell us the color first and we will work back from it.
These three are tied together, and understanding the relationship is how you pick the right wattage first time.
A laser line is at its brightest when it is at its narrowest. Widening it spreads the same light over more floor, so every extra centimetre costs brightness. That is physics, not a limitation of any one unit.
Mounting height pulls in the same direction. The higher the fixture, the further the light has travelled before it lands. The manufacturer’s own guidance: at around 10 m you can run the line at its widest; by 15 m you should run it at its thinnest to keep it reading clearly.
So the practical rule is simple:
Tell us your mounting height and the width your site standard calls for, and we will tell you which wattage actually gets there.
A laser line looks its best when each unit only has to cover a modest length. Ask one projector to stretch a line a long way, or make it wide, and the same light is spread thinner, so the line softens toward the ends.
That is why our laser quotes often show two layouts: a best-quality layout with more units and shorter lines, and a budget layout with fewer units and longer lines, which may show slight dimming at the ends. You choose what fits your site and budget.
Every facility is different. Mounting height, ambient light, floor color and finish, and the length of each line all affect the result. Tell us about your space and we'll recommend the setup before you order.
Butting two units end to end works fine and the lines join cleanly. Two things to plan for:
For a multi-aisle or whole-site scheme, send the run lengths and ceiling heights through the quote form and we will come back with a unit count and a layout rather than a list of prices.
The standard fixture is indoor only and not weatherproof. Most of these live in warehouses, plants and distribution centers, where that is exactly right.
Where the line has to run outdoors or somewhere genuinely wet — an open dock apron, a yard, a wash-down area — select Outdoor Rated — Weatherproof Housing on this page for $88.88. That version is IP65 rated and is available on all four wattages. It is built into the unit at manufacture, so it has to be chosen with the order rather than added later.
These are rated for 12 hours a day of continuous operation — a full 12-hour shift with no shutdown and no cooldown period. Not 8 to 10 hours: twelve. That rating is identical at 10W, 20W, 30W and 40W — stepping up the power does not cost you run time.
Laser diode life is 20,000 hours, and that figure holds at every wattage; it does not drop at higher power.
Class 3B, at every wattage. Class 3B light is hazardous to the eye on direct exposure, which is why this product is mounted overhead and aimed down at the floor. It is not a fixture to install at eye level or aim across a space, and it should be fixed so it cannot be knocked into a new aim.
Walk a distribution center built or retrofitted in the last three years and almost everything on the floor is newer than the floor itself. Autonomous mobile robots run replenishment. Pallet shuttles work the racks. Scanners, sensors and a warehouse management system track every case in real time. The forecasts all point the same way: the autonomous mobile robot market is growing at roughly twenty percent a year, and a large majority of logistics operators now run some kind of robotic fleet for picking, put-away or pallet movement.
The markings on the floor underneath all of it are still paint. Laid down when the racking plan was drawn, worn thin by the traffic it was meant to organize, and increasingly describing a layout that has already changed twice.
That gap is the whole argument for a projected line. Automation makes floor space dynamic — and paint is the one part of the building that assumes it never moves.
Mixed traffic is the hard part. A forklift has a driver whose intent a pedestrian can read: eye contact, a raised hand, an engine note. An AMR has none of that. Its path can't be guessed, which is why automation vendors specify wider warning fields and lower speed limits in areas where people and machines share ground.
That puts real weight on the floor marking:
None of that replaces the guarding, sensors and speed zoning a robot deployment needs. It sits alongside them, doing the one job those systems don't: telling a person, at a glance, where they are allowed to walk.
Forklifts remain one of the most dangerous things in a warehouse, and the danger is concentrated in exactly the place a walkway line addresses. Federal figures put forklift-related deaths in the range of seventy to a hundred a year in the United States, with tens of thousands of serious injuries. Pedestrians are involved in roughly a fifth of forklift incidents — but account for more than a third of the deaths. Being struck while on foot is the single largest category.
Which is why the marking is not paperwork. A visible boundary between people and vehicles is the cheapest control available for the highest-consequence hazard on the floor.
We'd rather be straight about this than sell you a compliance claim that doesn't hold.
OSHA 1910.176(a) requires permanent aisles and passageways to be appropriately marked where mechanical handling equipment is used. The standard is performance-based — it doesn't specify a color, a width or a material — and OSHA has not published guidance saying a projected line satisfies that requirement on its own. A projection also goes dark in a power cut, which is exactly when people are moving through a building.
So the honest position is this. Keep permanent physical marking where the standard calls for it. Use projection for the work paint is bad at: zones that change, boundaries you want re-aimed rather than re-cut, dynamic hazards, temporary layouts, cold stores and wet areas where nothing stays bonded, and reinforcement on top of a painted line that traffic has worn down to a suggestion. Most sites that call us end up with both, and the projection is what actually gets noticed.
A remote is included as standard, and it does one thing: power on and off. No dimming, no color switching, no programming. For anything on a schedule, wire the fixture to the building's lighting control or a timer.
Everything you need to put a line on the floor, in the box:
Laser color is fixed at manufacture and picked when you order, so decide it before the unit is built. There is no gobo and nothing consumable: no bulb to replace, no disc to swap, nothing to re-order later.
Most real jobs here are multi-unit. Send us the run lengths, the mounting heights, the color your site standard uses and whether any part of it is outdoors, and we will come back with a unit count, a layout and a price through the quote form. Freight is included free to just about anywhere in the world.
No. The color is set at manufacture and cannot be changed after purchase — there is no filter, no swappable part and no field conversion. Because availability also depends on wattage (10W is red only, 20W is red or green, 30W and 40W give you green, red or blue), color is the first thing to settle rather than the last. Tell us the color your site needs and we will confirm which wattages can deliver it.
The projector and its mounting bracket, a remote control (power on/off only), and your chosen power cord — 6 ft to 75 ft. There is no gobo and nothing consumable: no bulb to replace and no disc to swap. Laser color is fixed at manufacture, so it is chosen when you order.
Yes on the 20W, 30W and 40W — all three adjust across the same 1 cm to 20 cm range. The 10W is fixed. What the higher wattage buys is brightness at a given width, not extra width. Remember the trade-off: a laser line is brightest at its narrowest, and the higher you mount it the thinner you should run it — around 10 m you can run it at its widest, by 15 m keep it thin.
Yes. Every unit is manufactured with a wide-voltage input of 110–240V AC, so it runs on standard US 120V mains straight out of the box — and on 220–240V anywhere else without a converter.
Line length = mounting height × the ratio for that wattage. 10W is 1:1.8, 20W is 1:3, and 30W and 40W are 1:4. So at 20 ft of mounting height that is 36 ft of line from a 10W, 60 ft from a 20W and 80 ft from a 30W or 40W.
Divide the run length by (mounting height × ratio) and round up. A 200 ft aisle at 20 ft height needs three 30W units, or four 20W units. Wattage is a unit-count decision as much as a brightness one — send us the run lengths and heights and we will do it for you.
10W is rated to 6 m (about 20 ft). 20W, 30W and 40W go to 10 m (about 33 ft). That height limit is usually what rules the 10W out of a high-bay building.
It depends on the wattage: 10W is red only, 20W is red or green, and 30W and 40W give you green, red or blue. Green reads brightest to the eye at the same power, which is why it is the usual pick for a busy floor. If a site standard fixes your color, that decides your wattage — tell us the color first.
Up to about 20 cm (8 inches) at maximum projection distance, and it changes only slightly with distance. It is a bold band rather than a hairline, which is what you want on a floor.
Not quite — it is brightest at the center and slightly dimmer toward each end. Plan your overlaps so the dimmer tails meet each other, rather than leaving one at a doorway or a blind corner.
Yes, and butting them end to end joins cleanly. But there is no auto-alignment or sync — every fixture is aimed by hand, so budget commissioning time on a long run. Keep the mounting height consistent if you can: mixed heights still form a continuous line, but the brightness visibly changes at the transition.
The standard unit is indoor only and not weatherproof. Select Outdoor Rated — Weatherproof Housing on this page for $88.88 — an IP65 version, available on all four wattages. It is built that way at manufacture, so it has to be chosen with the order rather than added afterwards.
Yes — it is rated for 12 hours a day of continuous operation, which covers a full 12-hour shift with no shutdown and no cooldown period. That is the same at 10W, 20W, 30W and 40W, so stepping up the power does not cost you run time.
20,000 hours, and the figure does not drop at higher wattages.
Class 3B at every wattage. Class 3B light is hazardous to the eye on direct exposure, which is why it is mounted overhead and aimed down at the floor — never at eye level, never aimed across a space, and fixed so it cannot be knocked into a new aim.
Power on and off, and nothing else — no dimming, no color switching, no programming. For scheduled operation, wire it to the building's lighting control or a timer.
Several lasers along one aisle? Use one remote per laser. The remotes all send the same signal, so one remote pointed at several units mounted close together causes interference and they respond erratically. If they are close together, ask for custom-coded remotes when you order (additional fee) so each one switches only its own laser — or wire the whole run to one switch or timer.
No — this fixture only projects a line. For text, arrows, logos or safety symbols on a floor, use the Walking Light gobo projector, which takes custom full-color gobos.
Floor marking has always meant paint or tape — bonded to the slab, worn down by traffic, and a job to change. A line made of light does not wear, moves when the layout moves, and leaves the floor exactly as it found it. Join The Projection Revolution ∞
Not on its own, and we would rather say so plainly. OSHA 1910.176(a) requires permanent aisles and passageways to be appropriately marked where mechanical handling equipment is used. The standard is performance-based - it names no color, width or material - but OSHA has not issued guidance treating a projected line as satisfying it, and a projection goes dark in a power cut. Keep permanent physical marking where the standard calls for it, and use projection for what paint is bad at: zones that change, dynamic hazards, temporary layouts, and reinforcement over a painted line traffic has worn down. Most sites run both.
In some places yes, in others no. Areas with no permanent-marking requirement - temporary staging, seasonal pick zones, a robot lane during commissioning, a cold store where nothing stays bonded - can run on projection alone. Permanent aisles and passageways where powered equipment operates should keep their physical marking, with projection layered on top for visibility. The question to ask about any given line is whether it is a permanent aisle under the regulation or an operational boundary you control.
Three moments. During commissioning, when the layout changes weekly and every change would otherwise be a repaint. In mixed-traffic aisles, where people cannot read a robot's intent the way they read a forklift driver's and the separation has to be visible rather than remembered. And at the interfaces - induct and drop points, charging areas, the mouth of a robot lane - where a person crossing at the wrong moment is the actual risk. It sits alongside the robot's own sensors and speed zoning, not instead of them.
No, and you should not design as if they do. An AMR navigates by its own map, LiDAR and fiducials. The projected line is for the people sharing the floor with it. If you want the vehicle to change behavior at a boundary, that has to come from the robot's zoning or the safety system, not from a light on the floor.
It can, and this one is worth checking before you order. Some older AGVs navigate by tracking a physical line - magnetic tape, painted stripe or an optical guide path. A bright projected line crossing or running parallel to that guide path is a real risk on an optical system. Tell us what your vehicles navigate by and we will tell you where the projection can safely go, or recommend a color that will not be mistaken for the guide path.
Painted safety lines generally run somewhere between one and five dollars per linear foot installed, depending on paint type and how much surface prep the slab needs. The number that decides it is not the first coat, it is the cycle: traffic paint in a busy aisle is often back on the schedule every twelve to eighteen months, epoxy every three to five years, and floor tape in forklift traffic sooner than either. A projector is bought once. Work out how many times you would repaint that run over five years, add the aisle closures, and compare that with the fixture count.
More than the paint. The aisle has to be cleared and cleaned, the old marking stripped or scarified, the new line masked and laid, and then it has to cure - a couple of hours before foot traffic on standard paint, and twelve to forty-eight hours before heavy forklift traffic on an epoxy system. That is a working aisle out of service, usually on a weekend at premium labor rates. A projected line has no cure time at all, because nothing is bonded to the floor.
A single fixture is a bracket, a power feed and an aim - the sort of job an in-house maintenance team or an electrical contractor does in well under an hour once they are at height. The planning takes longer than the install. What matters is deciding mounting height, line length per unit and where the power comes from, and that is the part we do with you before anything ships.
It is designed to be installed by your own maintenance team or a local electrical contractor. There is no commissioning software and no calibration step: mount, power, aim. We will size the run, tell you the unit count and mounting heights, and stay on the phone during the first aim if that helps. For a multi-site rollout we will put the same spec in writing so every location gets an identical install.
That is one of the better arguments for it. Nothing is bonded to the slab, nothing is cut, nothing is ground off, and there is no coating to make good at the end of a lease. The fixture mounts overhead and comes down with you. Landlords who will not approve a floor coating will usually approve a light fitting.
Yes. The remote does one thing - power on and off - so anything that switches the circuit will switch the fixture. Wire it to the building's lighting control, a contactor or a time clock and it follows your shift pattern without anyone touching a remote. There is no dimming and no programming to integrate.
Not directly. It is a fixture, not a networked device: there is no API, no addressable control and nothing to commission on your network. What it does respond to is power, so anything your systems can switch, they can control. Sites that want a line on only during certain shifts do it through the lighting circuit.
The line goes out, the same as any light. This is exactly why we say projection supplements permanent marking rather than replacing it in areas that need a marking present at all times. If a route has to stay defined during an outage, it needs physical marking, emergency lighting, or both - and projection layered on top for normal operation.
Usually, and the variable that decides it is width rather than wattage alone. A laser line is brightest at its narrowest, so the same fixture that looks washed out at twenty centimeters can be perfectly crisp at five. High-bay LED lighting and daylight through roof panels are the hard cases. Tell us your mounting height, the run length and how bright the space is, and we will tell you the wattage and the width to run it at - or tell you it is marginal, which we would rather do before you buy.
Better than paint does. Pigment on a dark, sealed or stained slab has very little contrast to work with, and it gets worse as the floor ages. A projected line adds light to the surface rather than color, so a dark floor is close to the ideal background for it. Polished and highly reflective floors are the case to flag - they can throw a glare band alongside the line, which is a matter of aiming angle and worth mentioning when you tell us the site.
Cold storage is one of the strongest cases for it, because it is where conventional marking fails worst - adhesive tape lifts and paint is a serious job to lay and cure at temperature. The fixture is mounted overhead in the same air as your lighting. Tell us the operating temperature of the space when you enquire and we will confirm the unit for it rather than guess.
Effectively none, beyond keeping the lens clean. There is no gobo, no bulb and nothing consumable. In dusty environments - sawmills, cement, dry bulk handling - wipe the lens on whatever schedule you already clean high-level light fittings on, because dust on the lens dims the line long before the diode weakens.
Between ten and forty watts per fixture. A 30W unit running twelve hours a day is roughly 130 kilowatt-hours a year - a few dollars annually at typical commercial rates. It costs less to run than the light fitting next to it.
A mounting bracket comes with every unit, and the power cord is specified from six feet to seventy-five feet so the fixture can sit on a high-bay steel while the supply is somewhere else entirely. Beam clamps, unistrut and any site-specific steelwork are sourced locally, since what fits your building is a question for whoever is going up there.
That is how most multi-site orders start, and we recommend it. Put one unit over the aisle you argue about most, at the mounting height you would actually use, and look at it during a real shift with the lights on. It tells you more about width, color and unit spacing than any specification will.
OSHA does not specify a color for aisle marking, so most sites follow the ANSI Z535.1 conventions their people already read: red for danger, yellow for caution, orange for warning. Green is widely used for walkways and safe routes, and reads very well on gray concrete. Two practical constraints come from the hardware rather than the standard: color availability depends on wattage - 10W is red only, 20W adds green, 30W and 40W give green, red or blue - and green is the most visible to the human eye at the same power. Settle the color before the wattage, not after.
Yes, and it is the pairing most sites have not thought of. The laser unit draws the lane; a gobo projector puts a sign inside it - a forklift-area warning, a stop marker at a blind corner, a walking figure at a crossing, a keep-clear at a dock edge. They are two different fixtures doing two different jobs from the same ceiling. The line tells people where the boundary is; the sign tells them what the rule is.
Divide the run length by mounting height multiplied by the ratio for that wattage, then round up. A 200 ft aisle at 20 ft mounting height on 30W units gives 80 ft per unit, so three fixtures. The same aisle on 20W gives 60 ft per unit, so four. The wattage decision is as much about unit count as brightness, and it is worth doing the arithmetic before choosing, because the cheaper tier sometimes costs more once you total the fixtures.
Yes, and it is worth telling us at the enquiry rather than ordering site by site. We will write one specification that covers every location - wattage, color, mounting height, unit count per aisle type, cord length - so that a facility manager in one building and a contractor in another install the same thing. It also means a site added next year matches the ones already running.
Auditors respond to what they can see working, and a bright, unmissable walkway boundary generally reads well. Be straight with them about what it is: a supplement that improves visibility, not a substitute for the permanent marking the regulation requires. Insurers and auditors have their own criteria and we cannot speak for yours, so if a specific standard is being applied to your site, send it to us and we will tell you honestly where projection fits and where it does not.
Up to about 50 ft (15 m) on the 10W and 20W, and about 65 ft (20 m) on the 30W and 40W. Those maximums were measured in a well-lit warehouse, so a dim aisle or a dark sealed floor will go further. The practical limit is usually not the ceiling - it is that height and width pull against each other. Around 10 m you can still run the line at its full 20 cm width; by 15 m keep it thin or it starts to soften.
For most distribution center aisles, 15 to 25 ft is the sweet spot. It clears racking and forklift masts, it gives a useful line length through the projection ratio, and the beam has not yet spread far enough to soften. Below about 10 ft you get a short, very bright line - good for a single crossing or a dock edge. Above 30 ft you are trading brightness for length and should move up a wattage tier. Tell us your clear height and run length and we will give you the height to aim for.
It sets three things at once. Length, through the projection ratio: line length = mounting height x ratio, so the same fixture draws 60 ft at 15 ft and 100 ft at 25 ft on a 1:4 unit. Width, because the beam keeps spreading - a line thrown from 25 ft is wider than the same line from 12 ft. And apparent brightness, because that same light is now spread over more floor. Height and wattage are picked together for exactly this reason.
The ratio is the fixed relationship between how high the unit is mounted and how long a line it draws, and it is set in the optics at manufacture - 1:1.8 on the 10W, 1:3 on the 20W, 1:4 on the 30W and 40W. It is not adjustable afterwards. It matters more than wattage because it decides how many fixtures your aisle needs: a 200 ft run at 20 ft mounting height is three units on 30W and four on 20W. Work the unit count before you choose the tier, because the cheaper tier sometimes costs more once you total the fixtures.
Pick it from the run length and how much light is already on that floor, not from the price. 10W suits short runs and low mounts - a single crossing, a machine boundary, a doorway - and is red only. 20W is the standard warehouse aisle in ordinary light, and the most common choice. 30W covers long runs, high bays, or a floor with real daylight on it. 40W is for the longest runs and the brightest floors: dock aprons, daylight through roof panels, high-bay LED. Send us the aisle length, the clear height and how bright the space is, and we will name the tier.
The ratio is identical at 1:4, so both draw the same length line from the same height, and both offer green, red or blue. What the 40W buys is edge brightness at a given width. On a dark or dim floor the 30W is the better value because the extra output goes unused. On a dock apron in daylight, under high-bay LED, or where you need the line at its wider settings and still crisp, the 40W is what holds the edge. If the floor is bright, go 40W; if the run is simply long, 30W is usually enough.
Only because the higher tiers carry a longer ratio, not because of the power itself. A 10W at 1:1.8 gives 27 ft from 15 ft up; a 30W at 1:4 gives 60 ft from the same height. Between the 30W and the 40W - same 1:4 ratio - the length is identical and the extra wattage buys brightness. So wattage changes the length only where it changes the ratio.
Divide the run by mounting height x ratio and round up. At a typical 20 ft mounting height on 30W units (1:4), each fixture covers 80 ft: a 100 ft aisle takes two, 200 ft takes three, 300 ft takes four. On 20W units (1:3) at the same height each covers 60 ft, so the same aisles take two, four and five. Mount higher and the count drops. Send us the run and the clear height and we will do the arithmetic and tell you where the joins should fall.
Put them where a person is least likely to be reading the line - away from a crossing, a dock door or a corner - because there is no auto-alignment between units and the overlap is aimed by hand. Two fixtures placed sensibly along a run beat one working at the limit of its ratio, which is the usual mistake: the last few feet of an over-stretched line are the first to soften.
Yes. The beam keeps spreading, so the further the fixture is from the floor the wider and softer the line lands. On the 20W, 30W and 40W the width is adjustable from 1 cm to 20 cm, which gives you room to compensate - mount high and run it thin. The 10W is fixed. And remember the trade-off underneath all of it: a laser line is brightest at its narrowest, because the same light is concentrated into a narrower band.
It is designed to be aimed down at the floor, and that is where the ratio figures come from. A modest tilt to reach across an aisle is normal and is what the bracket is for. A steep angle stretches the far end of the line and dims it, the same way any projection loses brightness off-axis, so if you are trying to cover ground the fixture cannot reach from above, the answer is usually a second unit rather than a sharper angle.
The same heights apply - up to roughly 50 ft on the 10W and 20W and 65 ft on the 30W and 40W - and cold storage is one of the better cases for it, because the floor marking alternatives fail there first. What we ask for is the operating temperature of the space, so the unit is confirmed for it rather than assumed.

A laser line is brightest in the middle and slightly softer at both ends, and the effect grows as one unit is stretched to cover a longer or wider line. If the ends look faded, blurry or less bright, trim them off with the length and width control on the front of the projector: shorten the line a little and keep it narrow (about 3/8 in), so only the solid part shows. For the most solid line from end to end, choose the 1:1.2 lens or add a unit so each one covers less length. Mounting every unit in a run at the same height keeps the brightness even.
Many warehouses go with a bigger ratio, 1:4, to stay within budget: each unit draws a longer, thinner line (up to 4 times its mounting height), so you need fewer units, but the ends can fade. If budget isn't a concern, we always suggest the 1:1.2 ratio. Each unit draws a line about 1.2 times its mounting height (about 18 ft from 15 ft up), and it's the crispest, most evenly bright line. In-between ratios, such as 1:2 or 1:3, are also available, balancing line quality and unit count. Ask us and we'll price one for your space. Results also depend on your mounting height, lighting and floor finish, so tell us about your site and we'll recommend the right layout.
Many warehouses go with a bigger ratio (1:4) to stay within budget, but we always suggest the 1:1.2 ratio if budget isn't a concern. In-between ratios, such as 1:2 or 1:3, are also available.
The ratio tells you how long a line each projector draws compared with its mounting height. With a 1:1.2 lens, a unit mounted 10 ft up draws about a 12 ft line; with a 1:4 lens, the same unit draws about a 40 ft line. A longer line spreads the same light further, so the 1:1.2 lens gives the brightest, most solid line, while the 1:4 lens covers more floor with fewer units and the ends look softer. The ratio is set when the projector is built, so choose it before you order. If the ends of any line look faded, trim them with the length and width control on the front of the projector. Not sure which to pick? Tell us your mounting height and line lengths and we will recommend one.
