First off, these pictures don't really do it justice. It's freaking bright, like 10x brighter than these pics, with amazing flood. The first pic is from about 100 feet away from a fence on a driveway about 20 feet wide. It lights the whole thing up clearly, and the fence. The second is the side of my house from about 30 feet away, again, it looks much more impressive in person. The third is the driveway again, but pointed a bit more down in an attempt to show how that it is in fact bright.
I found this
while looking for better clearer shots, and while this one is quite blurry, it's much more true to life than mine. Darn phone camera. :/
It works well with Alkaline and NiCads, I can't say there is much of a difference in brightness.
Basically, I'm quite happy with it, I think it will work quite well
Did I mention stinking bright and great flood?
