Latest project for me is this Ultrafire WF-501B light.
Mods include swapping the driver to a 1400ma AMC 7135. Using a 30mm aspheric ground down to fit, a aluminium spacer fitted between the LED and Pill to get the correct focal distance and boring out the reflector to take the aluminium spacer.
Result is a 5.7 degree focused beam or a nice defocused 10 degree beam. Basically the same result I get with the W200/R2 light I build.
Aspheric lens is from Ahorton and Light is from DX.
I have built several similar using a 4 deg aspheric and sold them as rifle lights but I find this lens much more efficient. Its nearly as bright but nearly 50% wider angle.
