I swapped the emitter for a XPG2 noctigon (IOS) sliced, on the stock driver. It is driven at ~2A, which is really low but it does throw. The hotspot is noticeably smaller (duh), and this time I went for the +6000k emitter for the throw and visual color dominance. This is the point of large aspherical lens flashlight after all.
I was thinking of getting the MTN-MAXlp driver: here but it is rather expensive for 35$ (with shipping). I wanted the 5.5A, or the 5.1A, but I am not sure which one to get. Will the led be okay at 5.5A all the time? It should… It has to be a buck driver to use the full potential of the led, because a single cell cannot drive the xpg2. If you can think of a buck driver for +5A on two cells which is cheaper please tell me. I have searched the whole internet (I think) and they are really scarce.
X5/X6 Astrolux driver from banggood is probably the cheapest way for a direct drive driver if you are in Europe. Certainly works out cost effective for me.
I run my UF direct drive with an XP-G2. Although I admit, not for long runtimes as a rule. But can’t see why it wouldn’t be ok.
I have BLF A6 Fet driver. but this is a 2 cell light. I would like to have a 2 cell buck to fill up +5A in the driver even on medium or low batteries. One cell can give 4A on full, but under 4V it will be considerably less.
A friend of mine gave me once LedLenser A5 for nothing. It was out of order so I've challenged myself to make it working. So I ordered a https://www.fasttech.com/products/7522200 and a https://www.fasttech.com/products/2116105 . Put everything together making on purpose the warmest Lenser ever (at least I hope in AA class). A plastic pill - required some adjustments. Had to file grooves for wires, made drilled holes for screws. I've replaced optics because the original one was dedicated to THT diode type and was too short. But 20mm Convoy frosted lens fits perfectly. Here's some pics:
