I've been reading about the Ott lights and was told that if the lighting is the only feature you are after, than just buy a special bulb and put it in your own lamp. I bought one of those GE spiral type bulbs which is a daylight 60 using only 13 watts and put it in a bridge arm lamp and it seems to work great. I use it for cross stitching. It says it is an 8000 hour long life. Anyone else tried this?
