Hi, I'm looking to build a triple or quad Xp-E2, haven't quite decided yet, to put in a P60 host (so 17mm diameter preferred, but not absolutely necessary if I have to change hosts), with dtp pcb and some narrow spot Carclo optics. The Vf on the red xp-e2's is considerably lower than the other colors/tints, so if I want to run 3 red xp-e2's in parallel, can anyone recommend a decent driver for this application? I'm not very experienced by any means, but after searching the forum and internet for a while, no obvious driver choices come to mind. Would things be a lot easier if I changed the theoretical setup a little? For example, running the LEDs in series with more than one 18650, etc..
My only idea so far would be modding an LD-4b buck driver for increased current, from stock ~2.4a to somewhere around 4.5a if this is possible. That way the buck driver would dissipate some of the difference in voltage between battery and emitter, and the light would be getting around 1.5a per emitter for really good output (by red led standards).
Does anyone know of a driver thats readily available or easily modded that would work for this lower vf? Thanks!
