Some LEDs are dimmable, not all. Each manufacturer uses a slightly different electronic design. Not all will work with Lighten Up! Unfortunately, most blink or flash. We like the idea of LEDs but we can't recommend any of them at this time.
Reasonably priced LED bulbs are not common. They also do NOT provide the natural reddish glow of a real sunrise like incandescent bulbs do.
At this time we continue to recommend using 60 - 100 watt incandescent bulbs. Halogen bulbs are a great alternative to the old fashioned standard incandescent bulb.
