Personally. This light is perfect the way it is. Best 180$ i have ever spent
The only thing i dislike about mine is that it is hard to clamp to a mount. That is why i am going to use my tax return on a m3t
Well, this particular model can be had with rechargeable(s) via CPF member AW as an alter-native "upgrade" battery-wise. Other than that, what BionicSniper said and it suits me fine.
