AWSOME someone else uses car window light reflectors like me. They have excellent heat diffusion, I use them for my DIY reflector hoods.
Those are sweet looking. Nice and compact, excellent internode development.
BTW check out the last page of my log to see my CFL DIY setup 248W/18K Lumens.

If your mechanically inclined then I'll tell you this....
If you carefully W/plyers screw off the metal screw cap on the bulb, you'll find that 2 wires stick out about an inch. They connect to the ballast and can be wired directly. also I'll note that although there is a positive and negative wire, It doesn't really matter which way you do it. Just be sure to get wire caps for all your connections.
