Got two today. Wish I had rated for the reviews, as they are not what I am looking for. These are motion activated not motion sensing. They work kind of like those towel dispensers that give you a paper towel when you wave your hand across the front. One wave =high, two waves = low, third wave off.
If you make your fingers into a piece sign you can sweep your fingers across and go directly to low.
I'm really looking for something that detects when you enter a room and doesn't stay on for more than a couple minutes after you leave.
It is very bright though. Even though the LED is in a diffuser optic it still casts a pretty spotty and splotchy beam . For total flood you can remove the optic.
If anybody wants one I'll ship it free.
