I use a set of bright lamps with a timer in the socket. I doubt the graduality would add much benefit, and I get much brighter light a lot cheaper than I would with any wakeup light. These days I also use a set of red lights in the evening before going to bed (melatonin suppressed mostly by blue wave length).
