I've done some reading about this one and the reviews all seem positive about this new product; Not necessarily the claimed 900 lumens (maybe more like 400-600) but a good amount of light for the money, only $90. So, I'm going to get one and test it out.
In case this one is way better than my aging Nightpro Elite 12w, here are the links:
