To be honest, with the Terralux you are better staying with the stock reflector if you want to maintain any throw and desire peak output. The 3W diamond is direct drive
I modified my MaxStar5 to Cree XR-E P4 WH on my 4D Mag. This works fantastic with the HS reflector. Soldered it in place with ArcticSilver5 under the pad. Still doesn't throw far, but makes a spot. Now I have the 130+ lumens I was supposed to get with the stock MaxStar5, and it runs 30F cooler. And it can be backed off for full flood.
How well does a Cree work with the Mag stock reflector?
