Love it, but know your needs. He doesn't offer it anymore, its extremely wide, turns night into day for 50-80 yards. I'm talking like 100 foot wide at 50 yards, and I do mean day. The driver is pretty sweet with 20 settings. Map light is the lowest setting, and is suitable to sneak through the house. He has a great product, built well, no disappointment. I use it to light up the property on the way to the barn, but if I want too look for deer across the creek at 400 yards I'll use the 4d. These are generalisation from my memory, I would need to go test to tell you how far out it is useful.
