I am doing some repair and replacment of some LED landscape lighting for a community assoc. and they are putting in new lights to replace the broken plastic ones so i get to keep all the broken fixtures, gutted the LED part out and already figured where to connect for 12V DC since they are normally 12V A/C. they are pretty bright. need to cut down the hugh heat sink and figure out how to make them water resistant, maybe some sort of coating, thinking on making a set of rock lights or some lights for the front of the truck, maybe a light for the interior. will post up pics when i make some stuff. here are a few pics of the light.

here is the light complete.

here it is, I think its 18W total.



they are bright, maybe not enough for driving lights but will work for maybe backup lights and rock lights.

 

That's an awesome deal you got yourself! Wonder what the Lumen rating on those things are? They look super bright!

 

good deal..

 

nice i bet them where pretty expensive new

 

Might want to check how the driver circuit is set up for those. There is a difference in something that will work on 12 volts (AC or DC) and something that will work in a vehicle, where you can get voltages of 14 volts or so. I had an LED light in my truck that is 12 VDC but when I run it with the engine on, it started burning out individual LEDs, due to pulling too much current. It is normally powered from an AC adapter and with no load, that puts out 12 volts or more, but under load, the voltage drops down to limit the current. I need to add a current-limiting resistor to let it work right with the alternator charging. If your light has a constant current driver, it may be OK as long as you don't exceed it's max. voltage rating.

 

yea i was thinking of that, when i had it hooked to a land scape power source I found that the DC voltage after the rectifier was 15v so 12-14 should be ok. i was powering it off the power supply at 13.8v for the pics. i guess if they burn out wilol have to figure something out. I am gona look for some coating for the circuit board to make it water tight.
