Boat Forum / Cruising / November 2004LED's for running lights?
Any info on this? The 12v single water clear led's are $1.67 and put out 11000 or 3300 mcd, whatever that is, some measure of how bright they are. The viewing angle is 30 or 60 degrees. The attraction is that current draw is almost nothing. I measured .023 amps for a single lamp. Also, I want to make an anchor light with 6 of the 60 degree lamps flashing so fast they look like they are all on- kind of like the moving pictures principle. A 555 timer chip, a capacitor, a current limiting resistor? In theory this would still only drawn the current of one lamp. Is any of this practical? Thanks again, mayteaze. I think your on the right track, I read somewhere that the traffic lights that use LEDs blink them off and on to save energy. To a person looking at them they seem to be on steady, but it is just a trick of the eyes (I think they said that they were off half the time!). There was also an artical in Popular Science about using LEDs for car headlights, the hours to failure was about twice the life of the average car and the fuel saved was said to pay for the lights several times over. I wish I could help you more, I am going to be following this link closely as I think you have a good idea and I want to hear other peoples ideas. Eric > Any info on this?

Over the last few years there has been a breakthrough in LEDs, both in light output and colors. You are going to see them used for everything, and quite soon. I have a book reading light and it is great. They are very bright, use very little power and last forever. Running lights would be great. Bill |
