Gotta mod your Astrolux? The C8A and C8T are really nice right out of the box.
The C8F also kicks arse, but it’s just Überbright, not necessarily a thrower. I’m pretty sure I got at least one of every version of the C8F, from the earliest ones right through to the 21700 version.
For a thrower, though, the C8T is hard to beat. It’s designed to be a thrower.
Sure, you can mod your Astrolux, but it’s time-consuming, there’s always the chance of accidentally hosing it, and the LED you swap in just might not be a good “fit” for the reflector (ie, need shaving or shimming to “fine tune” the focus). Or maybe I just got lazy…
