Two outdoor-ready add-ons: an Outdoor Waterproof Timer that automatically switches your projector on and off on a schedule, and an IP66 Waterproof Switch Cover that protects your outdoor power connection. Each is $68.88 and can be added right on the projector page.

Open any eligible projector, scroll to the "Outdoor accessories" section under the configurator, and tap Add. The price is included in your total and the accessory ships and installs with your projector.

The Outdoor Waterproof Timer works with every Infinity projector. The Waterproof Switch Cover is offered on outdoor/weatherproof models, where it is most useful.

A gobo projector is a light fixture that projects a custom image — usually a logo, pattern, or message — onto a wall, floor, ceiling, or building. "Gobo" is a small disc (glass or steel) with your design cut or printed into it; the projector shines a bright LED light through that disc so your design appears as sharp, focused light on any surface. It's a no-install way to brand a space or add signage: you plug it in, aim it, and swap the design whenever you like. Infinity Projectors' gobo projectors range from 35W to 1500W for indoor and outdoor use, and every projector includes two free full-color custom gobos.

They are essentially the same thing — the terms are used interchangeably. "Logo projector" describes the most common use (projecting a company's logo), while "gobo projector" is the technical name, referring to the "gobo" disc that holds the design. A logo projector is simply a gobo projector loaded with a logo gobo. The same Infinity projector can display a logo, a safety marking, a wedding monogram, or a seasonal pattern — you just change the gobo.

Yes. Infinity offers IP65-weatherproof outdoor gobo projectors built for buildings, storefronts, patios, and ground projection in rain or shine. Gobo projections are brightest and most vivid in low light — dusk, night, or dim interiors — so they look their best after dark. In full direct daylight the projected image washes out (this is true of all projection). For daytime visibility, choose a higher wattage (higher wattage = brighter projection), aim at a shaded or darker surface, and project a bold, high-contrast design. Our wattage finder recommends the right power for your exact distance, image size, and lighting.

A gobo is the small disc that holds your design — a piece of coated glass (or laser-cut steel) that slides into the projector so light passing through it casts your logo, monogram, or pattern as a crisp image. The name comes from stage-lighting shorthand for "goes before optics." Glass gobos can carry full color and even photographic detail; steel gobos project a single color. Swap the disc and the same projector shows a completely different design — and every Infinity gobo projector includes two free full-color custom gobos to start.

A bright LED shines through a gobo — a glass or steel disc carrying your design — and a lens focuses that light onto a wall, floor, or building, where it appears as a sharp image. Three parts decide the result: the wattage sets brightness, the gobo carries the artwork, and the lens sets image size (lens number × distance = image width, so our standard 0.33 lens makes a 3.3-foot image from 10 feet away). There's no screen and no construction: mount it, aim it, plug it in.

Throw distance is simply how far the projector sits from the surface it projects on. It matters because distance sets both image size and brightness: with our standard 0.33 lens, image width = 0.33 × distance — 10 feet of throw makes a ~3.3-foot image, 20 feet makes ~6.6 feet (in industry notation, that's a 3.0:1 throw ratio). Longer throws also spread the light over more area, so they call for more wattage. Measure your real distance first — it's the one number that determines the right lens and wattage for your job.

A gobo projector casts a fixed design — your logo, a monogram, a pattern — through a physical glass disc, while a video projector displays moving digital content from a media source. For branding and signage, the gobo projector is the right tool: it puts all of its light into one crisp image, stays razor-sharp outdoors, runs unattended for years, and costs less to buy and run. If you need full-motion video or constantly changing digital content, that's a video projector's job — we carry those too. If you need your logo glowing beautifully every night, choose the gobo projector.

Projection advertising is using projected light — usually a logo, message, or pattern from a gobo projector — as signage and marketing on floors, walls, sidewalks, and buildings. Instead of printing or building a physical sign, you cast the message in light: it installs in minutes with no construction, glows in a way flat signage can't, and the content swaps in seconds by changing a gobo disc. Businesses use it for storefront logos, event branding, sponsor walls, safety messaging, and seasonal promotions. It's at its best at night and indoors — like all projection, it washes out in direct daylight.

Usually well under a dollar a night. A 100W projector running a full 10-hour night uses 1 kilowatt-hour — about 17 cents at a typical US electricity rate (~$0.17/kWh), or roughly $5 a month of nightly projection. Even a large 500W outdoor unit is under a dollar a night. That's why businesses simply run them every evening: the marketing costs pennies. An outdoor timer can automate the schedule so it turns itself on at dusk and off at close.

From a few feet up to about 350 feet, depending on wattage and ambient light. As a guide from our wattage chart: a small 15W unit covers about 6 feet in a dark room, 80–90W reads clearly at around 20 feet in average light, and our 1500W flagship throws up to ~350 feet at night (about 230 feet in average light). Distance also sets image size through the lens, so the full answer is always wattage + lens together — our Projector Finder matches both to your exact throw.

Multiply the lens number by your distance: our standard 0.33 lens makes a 3.3-foot image from 10 feet away and 6.6 feet from 20 feet (in industry notation, a 3.0:1 throw ratio). Want a different size at the same distance? Change the lens — a 0.5 lens gives a 5-foot image from 10 feet, while a 0.2 lens gives 2 feet. One physics note: a bigger image spreads the same light thinner, so very large images may call for a step up in wattage. Tell us your distance and target size and we'll spec the exact lens.

On your own property — your entryway, patio, interior floors and walls — you generally don't need a permit; it's your light on your surface. Public sidewalks and streets vary by city: some treat a projected logo as signage under the local sign ordinance, while many don't address projection at all. The practical playbook: aim from your own property, keep the projection tasteful and non-blinding, and check with your city's zoning or sign office before making a public-sidewalk projection permanent. And because it's only light, you can always reposition it in minutes — no repainting, no removal costs.

Only with the owner's permission. Even though projection leaves no mark, casting your branding on a building you don't own or lease can be treated as unauthorized advertising and can draw complaints or fines. The good news: permission is often easy to get — for events, partnerships, or a great shared wall, many owners will happily approve a beautiful projection. Get it in writing and agree on hours, and you're set. On your own building, project away — that's exactly what these are built for.

No — a projection is only light, so it leaves no residue, heat damage, or marks on any surface. That's one of its biggest advantages over paint, vinyl, and adhesive signage: brick, marble, historic facades, hardwood floors, and delicate finishes are all completely safe, and the "sign" disappears the moment you switch it off. Modern LED gobo projectors also run far cooler than old halogen fixtures. Aim it, enjoy it, and change your mind freely.

Yes, with two caveats. Clean, untinted glass passes most of the light, but each pane costs roughly 8–15% of the brightness, and tinted or Low-E coated glass cuts more — so plan a wattage tier higher if your glass is coated. Angle matters too: aim close to straight-on, because steep angles through glass can create a faint double image from reflections. One distinction worth knowing: projecting through a window onto the sidewalk works with clear glass, but projecting onto glass so the image shows on the window itself requires rear-projection film or a frosted surface — clear glass won't catch an image.

The projection on the surface is completely safe to look at, walk over, and photograph — it's ordinary focused LED light, the same family as stage lighting. Normal courtesy applies to the fixture itself: don't stare directly into the lens up close, just as you wouldn't stare into any bright light. People crossing the beam simply cast a brief shadow — no harm done, and on a dance floor it actually looks magical. If you're projecting onto a busy walkway, mount the projector higher and steeper so passing bodies block less of the beam.

The LED engines are rated for up to 50,000 hours — at 8 hours a night, that can mean over 15 years of nightly use with no bulb to replace along the way. The housings are commercial-grade metal, outdoor models are IP65 weather-sealed, and the gobo itself is glass, which doesn't fade or wear. Every projector also carries a 1-year warranty. In practice, your design usually changes long before the projector wears out — which is exactly why gobos are swappable.

For most businesses, the gobo projector wins long-term. A neon or channel-letter sign is a permanent facade project — fabrication, installation, electrical work, often a sign permit — and the design is fixed forever. A gobo projector is one fixture you mount and plug in: no facade work, and when your logo or promotion changes you swap a gobo disc instead of commissioning a new sign. With LED engines rated up to 50,000 hours and electricity costs of pennies a night, the ongoing cost is minimal. The honest trade-off: projection is light, so it shines at night and in dim settings, while a physical sign stays visible in bright daylight.

For most storefront businesses, yes — it's one of the least expensive ways to get a lit, eye-catching sign. You pay once for the fixture, electricity runs pennies a night, and your first artwork is included: every Infinity gobo projector comes with two free full-color custom gobos, a free remote, and free shipping. When you rebrand or run a promotion, you swap a disc instead of buying a new sign. The honest fit-check: projection earns its keep for evening-traffic businesses — restaurants, bars, salons, venues, late-open retail. If all your traffic comes in bright midday sun, a projection won't be visible when it matters most.

Shipping is free on every projector — the price you see is the price to your door, and the two free full-color gobos ride along at no charge. The one exception is a standalone custom gobo order (gobos ordered without a projector): those ship for a flat $50, or $88 with rush 5–7 day turnaround. Also worth knowing before you order: custom items are made to your artwork, so they're non-refundable — which is why we proof your design with you before anything is produced.

Yes — we run a formal price-match program: if you find a comparable gobo projector for less, submit a price-match request from the "Found it cheaper?" link on any product page and we'll match the price. Your matched price still includes everything every Infinity projector comes with — free shipping, two free full-color custom gobos, and a free remote — so the matched number is the complete number, not a base price with add-ons waiting.

A ready-to-run package: the projector with its standard lens fitted, a free remote control, and — produced from your artwork — your two free full-color custom gobos, all with free shipping to your door. There are no required add-ons; the price you see covers a projector that's ready to mount, aim, and plug in. Optional extras exist if you want them, like an outdoor timer ($68.88) to automate your on/off schedule.

For a typical storefront throw of 10–20 feet in average evening light, 30–90W covers it: roughly 30–35W at 10 feet, 60–65W at 16 feet, and 80–90W at 20 feet, straight from our wattage chart. On a brightly lit street, step up a tier — about 60–65W at 10 feet and 120–150W at 20 feet. Measure your real distance and judge your light honestly, then let the Projector Finder apply the chart for you — the goal is the wattage your job actually needs, not the biggest number on the shelf.

Usually not — gobo projectors plug into a standard outlet, so most installs really are mount it, aim it, plug it in. You'd bring in an electrician only for the extras: adding a new outlet at the mounting spot, hardwiring a permanent architectural install, or running power out to a pole or sign structure. For scheduling, skip the wiring entirely — an outdoor timer ($68.88) switches the projector on at dusk and off at close automatically.

No — a gobo projector is a standalone light fixture. Your design lives on a physical glass gobo inside the unit, so there's no software, no Wi-Fi, no app, no media source, and nothing to update. Power it and it projects; the included free remote handles control from across the room, including starting or stopping rotation on models that support it. That simplicity is why they're trusted for years of unattended nightly running — there's nothing to crash. If you want a schedule, a simple outdoor timer does it.

A wedding monogram projection is the couple's initials, names, or wedding date cast in light onto the dance floor or wall — created by a gobo projector shining through a custom glass gobo of the design. Size follows the lens math: with our standard 0.33 lens, a projector mounted 15 feet up makes a monogram about 5 feet across — a beautiful scale for a typical dance floor. And unlike rented lighting, a purchased projector is yours after the big day: swap the gobo and the same fixture becomes a business logo light or home décor. Every Infinity gobo projector includes two free full-color custom gobos — your monogram can be the first.
