Such a simple concept I can’t believe I never thought about it! I stumbled across someone who used mirrors as “light shelves”—reflecting daylight onto the ceiling of a room, thereby dispersing more natural light. I would have thought the light might be too direct into the eyes, but if you mount them at the right angle, this is not a problem at all.
The best part is the actual result—the intensity of the light was more than two times greater than two T-8 fluorescent bulbs! So the room is actually brighter than standard lighting, for no cost or use of electricity—the only cost being that of the two mirrors, which are cheaper than shelves in any case! It’s a logical way to reduce energy consumption of lighting.
I thought this was a great idea. Anyone out there using/used light shelves? Would love to hear about your experience with them, and if they worked well for you.
