LEDs and other neat gadgets of all types

PostAuthor: Matthew » Fri Jun 18, 2010 5:38 pm

On another site guy talking about using these to make driving lights and headlights for bikes.

http://www.dealextreme.com/details.dx/s ... r.87047508

"This is a 900 lumen led. Actual output is less but its rated at 900lm. I have made multiple drive lights and bike lights out of this P7 using available circuit boards on the site. A 35 watt 5K HID bulb puts out 3500 lumens or less depending on the temperature and quality. One of these is near comparable to a stock headlight. My drive light was in fact brighter than my friends ford explorers headlights.

You could use this to do just about anything and only needs a inch dia. for a reflector (larger is more efficient) . Will need a good heat sink, can run them at partial power, and only 10 watts."

So if you could get three of these, and work them into a head light, and 2 driving lights, you could have a nice bright setup and draw less than the current system? How hard would it be to make this work in the current headlight? This could be a really awesome forum project, great find!

You wouldn't have high/low beam with using the LEDs for a headlight.

You could use 2-4 and use 1 or 2 for low and 2 or 4 for highbeams or make the highbeam switch work driving lights.
