Don’t be caught in the dark...

Nothing is worse than not having light when you need it. In today’s classrooms, we rely heavily on our technology. If the technology goes down, the classroom is crippled. Educators depend on their projectors for presentations. If the light bulb goes out, the projector is useless and the teacher’s lectures are interrupted and far less effective. 

To prevent this unfortunate occurrence, most projectors have been outfitted with a warning light. This light is connected to a timer and is designed to turn on when the projector lamp is approaching the end of its expected life. Since most projectors are mounted in the ceiling, it is difficult to read the labels describing the function of each indicator light. However, if you know where to look, you won’t have to climb a ladder just to identify your indicator lights.

The warning light on a Promethean projector is the yellow colored light next to the power indicator. If you see both a green and a yellow light next to each other, it is time obtain a replacement light bulb for the projector. You can buy replacement lamps by visiting our Web Store here.
