I've been lurking here for a while and finally decided to share what I've been working on. I'm using inverted totes with 2x60w CFL bulbs, and one 60w LED light. I had an idea for something very similar to Space Buckets when I was in college, so I was stoked when I found this community. CFLs and LEDs have made it all possible. I plan to do a more traditional bucket build in the near future.
A Space Bucket can be whatever you want it to be. The fun part is the DIY aspect, experimenting and innovating, finding out what works and what doesn't, learning from others, reading tons... It's a great hobby. These things are addictive. Hope you enjoy the build!
