Well, now it does. http://www.goldmine-elec-products.com/prodinfo.asp ?number=G19653 $6 for a 12V 900 lumen LED. And thanks to the EBR 1190RX, we know 2000 lumens is the legal DOT limit. So for under $20 in LED's, you have a lot of what you need to cobble together a very bright LED headlight. Yay! I have other projects to finish first, otherwise I'd have some on the way already.   Sparky Posted on Friday, October 18, 2013 - 05:40 pm:        Wow! Not being familiar with lumens, so with 2 of these side by side looking forward, would there be 1800 lumens?   Reepicheep Posted on Friday, October 18, 2013 - 07:06 pm:        Yes. You will need to heat sink them somehow, either a big chunk of aluminum or maybe a fan.   Bluzm2 Posted on Saturday, October 19, 2013 - 12:18 pm:        Bill, That would be an interesting project. A standard H7 bulb puts out around 1500 lumen. It would require 2 of these to get a small gain in output. However with the right reflector and such these would really be neat.   Reepicheep Posted on Saturday, October 19, 2013 - 06:08 pm:        Thats what I was thinking, right before I started thinking about all my other half done projects.
