Is this worth the effort? I just recently bought a cheap china HID and am toying with modding it with an aspheric lense to focus the beam... Id want to be able to go from a large beam or even flood to a throw beam.

I think this would be an awesome MOD as I don't think anyone has tried it yet. Because the aspheric lens would gather and focus the light, I think you would get some incredible lux ratings out of doing it. I would encourage you to do it just because I haven't seen anyone else do it.
As others have said, it would be an interesting project. However, you have to keep in mind that the radiation pattern from an HID is totally different than a LED, so the appropriate reflectors and lenses to use are likely different as well.
Again, it's not to say that an appropriate lens couldn't further focus the light from a given HID. But the usual aspheric that's put in front of a bare LED will almost certainly not give you the results you want.
Yea thats the concern I have I guess I could hover my 50mm aspheric over the lense to gain a basic idea of what might be possible. Also wondering if using a reflector combo would be better in this case rather then bare Aspheric. I dont have alot of exp with this stuff but do know a great deal about lenses and mirrors as I build telescopes. In any even should be fun playing around with it.
Was just thinking about this, it will work because I have projector lense HID headlights on my wifes car and they throw the light very well. I guess at this point I'm now looking for a lense lol
