Hi guys. I've very new to building your own light but want to out of cost of the ones on the market which are too expensive for me. I own a temp. adjustable iron, wick solder remover, solder pump, and solder. I have soldered my own cut & resolder new fans for my computer and power supply fans.

My knowledge on electrical is simple. Battery + wire + bulb = light. I can do the assembly work once someone has worked out the kit items and the math. I don't digest the details when reading a book I tend to be a hands on and 1 to 1 learning person.

I have seen some CREE and Luxeon LED's before and am looking for the brigtest setup. I own a NiteHawk AL-X right now. I am looking to build a small, yet bright LED helmet light. I have heard something about the Luxeon V LED's having the 'donut' issue. I'm looking to build a 5 degree spot helmet mount with a 100% and 10% power mode. Does anyone know if there are any 5W LED's without the donut issue?

I want to make this light powered by 4xAA batteries so I have the flexiblity to get batteries when I'm out in the field or touring then get screwed and have to look for a power cord to charge some power pack up.

Thanks.
