I had some stuff laying around, and decided to try if they fit together. The parts were:
-One Elly from DX
-One Asperic lens, 28mm from same vendor
-One G&P tactical bezel
-One SSC P4 U-bin star

I basically removed the stock star, lens, reflector and reflector-retainerring. I then put the Seoul-star in place with some thermal grease under it, with the stock star under it (turned upside down) to act as a spacer. I had to use some longer screws to make it stick.
I then assembled the G&P head without frontal o-ring, with the aspheric lens in place. Finally I wrapped the front-part of the Elly-head with some plumbers teflontape, and just screwed down the G&P bezel over it.

The focallength was pretty much perfect in this setup, and It projects a clear image of the LED-die on a white wall, approximately ten meters away. Outside it projects a beam that is practically useful for around a hundred meters, sadly there is no spill.

However, a nice mod to a cheap flashlight! :thumbsup:
 
Sorry about the sad quality of this picture...

Nice mod!

Any beam-shots? You do know that more light will hit the asperical lens with a Cree.

Sadly no beamshots, and I scavenged the light yesterday for some parts, so I guess its too late to take them:sigh:

But the beam was intense!! With a Cree it would be killing!
 
got a pic of the aspheric lens by it self? this setup intrigues me....:thinking: could one take say take a really large aspheric lens (say 12") and turn a regular handheld searchlight into a long distance thrower?
