Good morning, I have purchased an LED, driver and lens from ebay
http://www.ebay.com/itm/NEW-Cree-XH...er-/291709765712?_trksid=p2385738.m2548.l4275
however, the seller is unable to furnish me with a schematic of the driver.
I am trying to retrofit this LED into an Ray-O-Vac Sportsman flashlight to have some style with the efficiency of an LED. I selected the 5K LED, and the 25° Lens.
I am interested in confirming if the upper range of the voltage input and what the efficiency might be as the batteries are run down.
I would also like to ask for suggestions on how to heatsink the LED in the old style body. I was thinking of going on the lathe and turning down a piece of Aluminum, but I am not sure how to follow the contour of the bell end.
Is there an easier way to get some heatsink behind the LED and into the body of the flashlight?
I am still on the fence on weather to use the original reflector and machine off the back where the incandescent bulb went in or use the lens that came with the LED. I was presuming to machine off a 1/4"" to get the LED up to about the filament level since I assume the reflector curve is based on that focal point.
thank you for your time and have a good day
