I have a silver one. It's not a very good host for modding - the main reason I bought it. The Seoul ZLED is a star and is easy to replace, but the head doesn't look like it has much room in it for any drivers. I'd say it's probably less than a fenix but that's just by eyeball'ing it. I can't see how to remove the existing driver from the head. It probably comes out like a fenix module but I don't see the holes. Maybe they are under the LED or under a white piece of plastic in the base of the head. The switch looks like it will unscrew just like a fenix. The stock switch has a loud 'snap' to it. The reflector has a rather large hole that fits over the base of the LED. (like an IMS27). My biggest complaint is the finish. The knurling is OK but not great. The rest of the light has very small ridges to it that I can't stand. It just doesn't feel right to me, sort of like fingernails on a chalkboard.
In it's stock form it isn't too bad for the price. I don't use mine. If you want I can send it to you to play with. (I wouldn't be all that upset if you ruined it!!)
