I love mine, it really helps these old eyes....but I found mine much cheaper online by searching around a few years ago. I think before I buy another I will just try the daylight bulbs available out there for my own lamps. I'm not sure if ottlite has the regular screw in bases yet. Used to be they had strange bases that only fit in their lamps, thus you always had to buy their bulbs to replace :evil: That's how mine is. I'm guessing the wide spectrum daylite bulbs available now will do the trick..and fit my budget :-D
