He had an idea for a lighting experiment way more scientific than ours.
He hung a 4 inch can with a compact fluorescent bulb in our downstairs hallway (left) and a 6 inch can with our awesome LED bulb in Rob's studio (above Rob) and put a shower trim on them so we couldn't see the bulb.
You can tell by how blurry the photos are that the lighting isn't super bright, but it's the same quality as the $300 fixture we saw at Western lighting for, drumroll please, $27 plus tax and the bulb ($25 for the awesome LED and about $2 for the compact fluorescent.)
Hm. Guess we can afford to light the basement after all!
