What this fixture is good at
The applications that work share one property: the surface is controlled. Where a high power gobo projector succeeds — an architectural facade, a large advertising wall — somebody has thought about what is already falling on that wall. Where it fails, the unit is fighting daylight or a glossy, patterned surface it was never going to win against.
architectural facade: the straightforward install
architectural facade is the easy case for a high power gobo projector and the one to learn on. The surface is usually matte and light-coloured, the ambient light is known, and the viewing distance is short enough that 150 W is plenty. Get the throw right, keep the beam square to the wall, and there is very little to go wrong.
large advertising wall: lighting against competition
The large advertising wall case rewards site work over specification. Two identical high power gobo projector units in the same venue can look entirely different depending on which wall they are aimed at. Walk the space at the working hour, find the surface with the lowest existing illumination, and let that decide the mounting point.
Application three — industrial site
The industrial site install is where the survey earns its money. Throw distances at the top of the 15–80 m range, uncontrolled ambient light, and access that may need a cherry picker all need settling before the high power gobo projector is specified. Most disappointing results trace back to one of these being assumed rather than measured.
Recommended configuration by application
Match the configuration to the surface: matte and light-coloured surfaces give the most back, glossy or dark ones eat the image. On difficult surfaces, reduce the image size before increasing the power — it is cheaper and it works.
Three site questions
Three checks decide most applications: ambient light at the hour of use, the angle between the beam and the surface, and whether the image lands on something matte. A high power gobo projector that fails any of these will not be rescued by a bigger lamp.
