i had a tactical deben torch, 130 quid, i ended up taking it back and swapping it for deben tracer 1200 lumen, 130 quid aswell, the whole thing is light as,,,and the battery flows up to 8hrs full beam (has a flick dimmer) and just clips on and off your scope, iv had 3-9x40, 3-10x44, and 3-9x 50 hawke scopes, and not noticed any diffrence in the night, other than when you look at the scope lol and the weight..IR scopes help abit, but find it pointless having them go so bright, its just glares the scope
