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 outdoor use.

• Temporary wayfinding and safety signage

• Stage, architectural and hospitality lighting

FAQ

What throw distance can I expect? It depends on the 18° 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.

Included in the delivery

• BLPG-50E-R projector

How big is the image at a given distance?

With its 18° optic, this 50 W LED gobo projector throws a circle whose diameter is about 0.317 times the projection distance.

• At 3 m: image 0.95 m across

• At 5 m: image 1.58 m across

• At 8 m: image 2.53 m across

• At 12 m: image 3.8 m across

• At 20 m: image 6.34 m across

These figures follow from the optics alone: D = 2 × d × tan(18° / 2), i.e. D ≈ 0.317 × 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 3 to 13 m, giving an image 0.8 to 4 m across.

Because the gobo rotates on this version, the image sweeps a disc of that diameter: size the projection surface on the full figure, not on the height of the motif alone.

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.

Outdoors, the practical rule is to project after dark onto a light, matt surface, and to avoid dark, glossy or already-lit walls, which crush contrast whatever the power.

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

• Permanent outdoor installation, IP65: facade, canopy, pole, forecourt, terrace

• A rotating motif, to catch the eye where a static image goes unnoticed

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

• Gobo rotation is motorised: allow clearance around the optic and check that the logo reads correctly through the whole rotation.

• The 18° optic is factory-fitted. To enlarge the image you rarely move the projector: you change the angle. Going from 18° 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.

• IP65 covers dust and water jets: the unit stays outdoors all year. Clean the front lens twice a year — a film of dust costs more brightness than people expect.

• 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.
