I have finally converted to the LED craze. My old light for night riding (very old) was a Niterider 10W Halogen. After reading the various DIY threads here I decided to build my own. I gave my wife the list of components I wanted (2 Cree XR-E with a 1000ma Buck Puck) and Christmas was done.

I drive the system with a 7.2V battery pack from Radio Shack. I keep it in my Camelback. I made my own box and I get 400 lumens out of this little helmet mounted monster.

Thanks for the inspiration! I will post pix when I figure out how to attach them.

As a note, my kids (5 & 9) held the old halogen at night in the back yard, and I fired up the new light. They said "Dad, where did our light go?"

It was awesome!

Too Heavy

I tried it, but the 4 AA batteries did not have enough forward voltage to drive the LED's. But I think I'll put a single on the bars with a 20 degree lens and self contained batteries.

Jim, I was skiing at Mad River 1 week ago (awesome) where is the snow?

I was thinking 2 leds in parallel (rather than series) with a DX driver on each. Should work. I hope so, since that's the circuit and power supply of the helmet light I'm building now. (not self contained and no Altoids tin though)

It's mostly in the rivers now, flowing towards the ocean :( But this happens every December....it will return. The best snow is in March. We average 7' in March at Killington. (I tune skis part time there in the winter, for the free pass ;) )
