Nope, I haven't learned anything yet, although I haven't looked since my post. Back in the day a post like that would have had 20 responses by now. I guess that Tigerlight model is old news. My battery pack is shot, it doesn't last very long and I don't get the full brightness anymore. I'd like to upgrade it to lithium rechargeable or even just a rechargeable AA eneloop pack like the old ROP lights. I still have an ROP that I use often. That huge (nowadays huge anyway) 3D Mag body makes it so easy to find and grab, just like the Tigerlight. It's nowhere near as good looking or bulletproof as the Tigerlight though. There was a member who custom made the battery carriers for those and used really robust materials without springs, they last literally a lifetime. I probably have a dozen spare high output incandescent bulbs for that ROP, so I keep using it since it's handy and cost free to run. They're both about 200-250 lumens I'd estimate. I'd like to bump them both up to 500+.
