I got 5 "pretzel-shaped" CFL bulbs, each said to be equivlaent to a 100-W incandescent. I had a pole lamp and some other fixtures that would take a 'screw-in" base (I think called a "mogul base").
The 4-foot linear fixture might be better, but then I would have to hang it from something, and I don't do well with ladders any more.
I keep remembering when a 48" shop light could be had for $12-15, and refuse to pay $25-30.
I keep checking the Habitat for Humanity Restore, but then who will hang it, and how will I reach it to adjust it?
