Re: amps to watts Oh ya, they'd work great for that. Some of the rock crawling buggies have down lights. |

Most new high output LEDs are 1 watt, 3 watt, or 10 watt, with 100 watt on the way. The older LEDs are 1/2 watt. Thats probably what it has. Light output will be low. The stock PIAA lights, may be brighter. Check the lumen output. Just for comparison a good LED flashlight, with 2 AA batteries, puts out 100 to 300 lumens, at 1 meter. The Rigid Industries LED lights, I think are using 3 watt LEDs. Their Dually Light, puts out roughly 1300 lumens, with 4 LEDs. 1300/4 = 325 So they are getting about 300+ lumens per LED. There are a few watts use in the LED driver circuit and some of the power is changed to heat. Thats why they need cooling fins. LEDs are not on all the time. The control circuit, turns the LED on and off many times a second. The faster they can do this, the more light output they can get. This technology is what drives up the price. High output = high price. I hope this isn't to confusing and I know it can be. Just try to find the most output, to dollars, as you can. |

Re: amps to watts Power= intensity x electromotive force Or In laymans terms Wattage = amps x volts Or divide amps or volts by watts to get the other |

amps to watts I found a small cheap set od LED lights that would be great replacements for the stock lights. The problem is they only offer the amp draw and candle power, no wattage spec. Is there a way to convert the amp draw to wattage? The specs say the draw is .074 amps. |
