Hi,
I cannot say I have ever seen one like this before.
I am making an assumption it is a IR LED type so power consumption will be low. In my experience, if it is a smallish room, the IR reflects around a lot so gives reasonable results. However I would expect this will give a massive bright spot directly below it, which if the bulb is in the middle of the roof, pointing down will be a problem as it will cause the camera to flare.
If I was to use it, I would mount it either on tha same wall as the camera or in a desk mount lamp, shining up to the ceiling so you are only getting the reflected light, which will be more even.
If you do end up getting one, I would love to see or hear about the results.
