I will say one good thing about the light, it has me making a more regular wake-up time on my own without benefit of a startling alarm clock that had me pushing the snooze button and feeling worse about waking up. It does take some getting used to doing it on schedule, but if I'm up on my own - what can I say.
This particular light has three different brightness settings and three different timer settings. Now, I don't know if this type of light therapy is proven or not. I just know that to wake up willingly and not drag out of bed works for me.
