I can't seem to find any numbers on how far it throws on the max setting. Anyone know?
260 meters? That's it? I would assume 800 otf lumens and an optic design for throw and no spill will do a hell of alot better than that. Kinda dissapointing.I find 0.25 lux too little, when I tested mine in pitch darkness and with dark adapted eyes, I found it to give enough light to around 130 meters. Then the target is hit with approximately 2 lux. If your objective is to light up a white object against a dark background, then the throw will of course be much better, probably 260+ meters in optimal conditions.
Surefire doesn't want you to use rechargeables in the light, so they don't make it easy for you. 3xt3.7V RCR would presumably blow the circuit. Even 3x3.2V Li-ion would exceed specs and risk damage. In theory, 2x3.7V Li-ion could work, but the body bore width is too narrow for 18500 cells. If you could find 17500 cells, they may fit and work in the light. But your are presumably voiding your warranty if you do, since it outside their supported cells.Hey guys, I just had a question. Can you use some rechargeable batteries with this light? I am new to alot of this terminology. Basically just looking to see what options there are to use rechargeable batteries (and which ones)? Thank you.
Probably best if you ask the experts in the batteries subforum. But simply put, there's a difference between nominal voltage (i.e. "typical" over the charge capacity of the cell), and maximum voltage when fully charged. That latter one is what you have to watch for - the common "3.7V Li-ion" is in fact ~4.2V fully charged. Not sure about all the supposed "3.0V" or "3.2V" nominal cells, but I imagine a lot of those make it up ~3.6-3.7V fully charged. Standard "3V" is also typically ~3.2V fully charged.Thank you for your reply selfbuilt. Are there no rechargeable CR123A's that are exactly 3V?
Sorry if the question is stupid, I am new to rechargeable batteries.
Hi 880arm,Cool video. I always wondered what would happen if I removed those two screws!
Thank you for sharing.
Just got the UB3T, and I must say it is awesome!! By far the best "big" light I own.
Is Surefire shipping the newer 1000 lumen UB3T's and M3LT's or 1200 lumen M6LT?
Thanks for doing a Google search that pointed to a yes.
