Only the driver is different, 30% light increase, with a probable 30% increase in current draw.I only bought the basic version from kaidomain, I recommend getting one of the upgraded versions from shiningbeam.com, I really wish I had because I love this light so much.
The VersaTi ET10 has no reflector and it puts out an even and wide circle of light:
I think goinggear sells it, although this review kinda turned me off to this light:

A flood light for my keychain does sound really nice for my needs, but the output and runtimes don't really seem up to snuff imo.
Where can I get this kind of light?
I think this will be great in my Flashlight headband
I just ordered a Quark Mini AA for my headband since many reviews this a flood light.:twothumbs
