Long time ago I bought a Keylux AA with turbo head. Today I finally finished my Cree XR-E canister light engine but to my surprise the head doesn't screw down enough for the LED to meet the reflector . :thinking: Distance between the back of the reflector and the metal ring of the XR-E is about 5mm. I really don't see how to get the Keylux to work with the turbo head... or am I missing something? :candle:
