The F3X is on the way from china. i could not resist for this discount price (although i know modding is not easy). But i like the look (like the big brother of the D80). djozz modded one but the unusual led spacing makes it hard and fits no other DTP Board (Mod: LuckySun F3X). That was the reason why i was looking into uv leds. They usually not require huge currents.
But thats no problem! In time i will find something that fits the light. If necessary i change to a single reflector (if i can find one). But i am not in a hurry!
