I don't know if everyone is talking about the same thing, but the one I have, called the Bendable Bright Light, is an LED light. I use it sometimes, but I find that it has too much glare - when I mentioned this to the eye doc a couple of days ago he agreed that LED lights are "blue" and can bother your eyes because the light is so concentrated in one place.
I much prefer my ott-lites which are natural daylight lamps.
