Default LED rock lights

So, I've been interested in doing this for a long time and I finally got some stuff together. Here is a shot at my first "real deal" rock light. It puts out 168 lumens (a little brighter than the standard XJ reverse lights I think) and only consumes 3 watts. The housing is aluminum and it is water tight and pretty much indestructable. You need a $20 unit to convert the power to run up to 6 of them. I'll post more pics up soon. I'm going to set up a website soon and see if I can sell some of these things for about $15-$20 each. The only other place that sells anything like this right now is roundeyes, but theirs are not nearly as bright as these. I'm also making 2 more mounting options as well. Let me know what you think. I can get them in different colors as well and controlers that have dimming and strobe effects too.



Side view


control unit with wiring harness and dimmer


Flush mount to be mounted on the back side (of a bumper or rocker or whatever) with a 1/2" hole drilled for the light to pass through.


I tried to get the exposure on these close to what it looked like to me

3' from the door


8' from the door (this one looks a little dim on the computer)

$15 each for anyone on GL4x4 and $20 for anyone else is what I'm thinking. I'd like to see what some colored ones look like on a nice bike too.

I'd like to see a couple more pics. I may be in for a couple for the jeep. I have the bike too(in my avatar). I have a bunch of red leds I've been meaning to put under my fairings to make it glow red. I would bet I'd have to put a bunch on though to get a uniform glow. leds are just to direct in the direction the light goes.

on that same note, how much of an area do they light up, or would a guy need like 10 under the jeep? Also, your first post says you need a $20 unit to control them. So that is on top of the 15 a piece?

They run on 3.7v and draw 1 amp, so you need an led driver to give them the right current from you battery.

Yeah, the unit will run 6 of these lights max. As for brightness, I'll get some pics tonight.

Also, I would suggest buying one of them and powering it with 2 aa batteries. This will give you a good idea of how many you will want. If you decide that you don't want to buy any, just let me know and I'll give you a full refund.

turned out great! I will be in for some for sure. How big is the converter box and do you have a source for them? I'm glad to see they got to you by the weekend too.

Here's the driver http://www.luxeonstar.com/buckpuck-1...-mount-p-7.php and you also need a $5 wiring harness. It's very very small (0.78x 0.78x 0.43 and weighs just 0.3oz) so you'll be able to put it anywhere. PM me if you want some.

First time I've ever heard of a driver. Most people just use a resistor. There are resitor calculators on the net that let you input the source voltage, led voltage, current wanted through each LED, how many in the circuit, and are they parallel or series. A LOT cheaper than running a driver, that way you just need a switch to run them, and a resistor for each circuit. Back when I did my Nylint (remember them?) I also found some cicuit board mount led's that had a 105 degree angle/

leds are very sensative to voltage, so if you have 12-14v input there is a fluctuation that could burn out the diode. this driver is more efficient too, and has overload protection. General Lee can fill you in more.

Cree 7090 3W Q4 LEDs. For about 5 dollars more, you can get 228 lumens, and in a while I'm going to play with their 12w 900 lumen diode. That's as bright as a 35w hella h3 bulb, but draws 1/3 the power and lasts 50 times as long.

Those will be about $35 each, but I still have to play with those to see how much heat sink they need. Those will each need a driver as well unless someone comes out with a bigger driver. I'll let you know when I get one of those designs made though.
