I was thinking xpg2.
It finally arrived and I fudged the reflow.
So, I took an xml2 5k, trimmed a 16mm pcb to fit, widened the reflector hole and stuck that in there. It didn’t have quite enough throw for what I’d like to use this for, so I de-domed it.
I also trimmed a pt-54 (red) to fit the generic LED side. The PT54 came in some sort of assembly (for a projector?) - heatsink and two glass aspherics. The smaller aspheric is a perfect fit for the hole in the bezel. It sits directly on the PT54. The lens has a very short focal length, and sitting on the emitter it still focuses the beam, which is just slightly narrower than the reflector side - akin to a zoomie pushed 1/3 forward from full flood.
To help radiate heat, I sanded and painted the outside of both aluminum pieces (black), and I cut out the sections of the housing that are slotted, and the section dotted with holes.
Finally, I installed a kaidomain coated lens on the reflector side. At some point I will spray the driver with plastidip just for peace of mind if I get caught using it in heavy rain. I also plan to wedge a piece of aluminum or copper between the two aluminum heads, effectively doubling the heatsink mass/area available to each emitter.
And, here’s some GREAT news on this light. Soft switch presses change modes!
ie, if you have the reflector side on, a soft press goes to a ~medium mode, another soft press goes to strobe. The other side has just high and medium.
This light is awesome!!! 5 modes, two emitters, wide voltage range, easy to adjust angle, budget price…
I will definitely end up buying more.
I may even end up buying one just to rob the driver for something else…
I think next time I’ll put xml2 with dome on reflector side and dedomed xpg2 on the other side, with another tiny aspheric and spacer for some serious throw (for headlamp size anyway ).
