Why choose a LED gobo projector

Project a logo, a message or a decorative pattern onto any surface with no heavy installation work. A silent, low-consumption alternative to painted or printed signage, suited to indoor use.

• Temporary wayfinding and safety signage

• Stage, architectural and hospitality lighting

FAQ

What throw distance can I expect? It depends on the 20° optic and the 50 W output - typically 4 to 18 m. Beyond that range, move up in wattage or choose a narrower beam angle.

Is a gobo supplied? One standard gobo is included. Custom gobos - your logo, a slogan, a seasonal pattern - are available as an option, in glass or metal.

How big is the image at a given distance?

With its 20° optic, this 50 W LED gobo projector throws a circle whose diameter is about 0.353 times the projection distance.

• At 3 m: image 1.06 m across

• At 5 m: image 1.76 m across

• At 8 m: image 2.82 m across

• At 12 m: image 4.23 m across

• At 20 m: image 7.05 m across

These figures follow from the optics alone: D = 2 × d × tan(20° / 2), i.e. D ≈ 0.353 × d. They depend neither on the gobo nor on the wattage — the beam angle, and only the beam angle, sets the image size. A medium aperture like this one is chosen for a throw of roughly 2 to 11 m, giving an image 0.8 to 4 m across.

On this fixed-bracket version the throw distance is locked at installation, so it must be settled before drilling, working back from the image diameter you want.

Choosing the wattage

At 50 W the image stays readable on light surfaces under strong ambient light, and over longer throw distances.

Image illuminance falls with the square of the distance: doubling the throw divides brightness by four. Conversely, holding the same image brightness while moving back requires power to rise with the square of the distance — going from 20 W to 40 W buys roughly 40% more throw, not twice as much.

Typical applications

• A floor logo in front of a store, hotel, showroom or reception entrance

• A pattern on a wall or shopfront a few metres back

• Temporary signage for an event, a trade show or a retail campaign

• Indoor installation, IP20: shop window, technical ceiling, track, suspended ceiling

In every case, readability depends first on contrast: a light, matt surface with little other light on it beats a higher wattage thrown onto a dark or glossy background.

Installation and operation

• A fixed bracket means the framing must be settled before drilling: run a projection test at night or in low light first.

• The 20° optic is factory-fitted. To enlarge the image you rarely move the projector: you change the angle. Going from 20° to a wider aperture multiplies the diameter without moving the fixing point.

• Focus on the lens ring at the final throw distance: an image sharp at 3 m is no longer sharp at 8 m.

• One standard gobo is supplied. Custom gobos come in metal (cut motif, single colour, very durable) and glass (colours, gradients, photographic). Glass is essential as soon as more than one colour is involved.

• IP20 restricts the unit to indoor use, away from splashing water and salt spray.

• 220-240 V supply, stated MTBF 25,000 h. Switch it with the site lighting rather than running it permanently: useful LED life is extended accordingly.
