I got my H602 W XM-L2 light on Friday, and put it to use on Saturday in a new pit I found. While it is certainly bright, it appears that my GoPro needs even more light to work with. I may have to experiment with some of the settings to see if anything improves. As far as the overall impression of the light, it is very nice. The warm color and wide flood remind me of carbide, except a lot brighter. And of course without the smell, hassle, and other negative aspects of carbide. As far as the batteries, time will tell how they work out-so far, so good.
