I DON'T LOVE OTT LIGHTS. I bought 2 at a half price sale. Removing the 1st bulb ended in damaging the lamp. so that was one less light to deal with. The 2nd one is still working, but seldom used.
I went to BigLots in Dec. 2007 and saw the Full SPectrum lamps, with florescent bulbs (an extra bulb FREE with the floor model that was $29.99.) I liked it so well I bought 3 more. I use one to read by in my living room. I bought one table model for $24.99 that I have on my cutting table. I don't know what the light intensity is but it has a 4 tube bulb that can be easily replaces. I have not yet had to replace one bulb, but have all those spare bulbs for when the time comes. Prices may not be the same now, but they are GOOD lights for close work.
