Homemade LED light bar

I have about $235 invested in it and yes, there are different optics. I went with 4 spot and the two outside lights are elliptical optics. I would just go with all spot since it is 24° FWHM and that is plenty.

 

if you want to make another one... let me know.

 

subbd for a later use - I like the project!

 

I thought I would give an update. The lightbar is still going strong. You never know when you make something for the first time...

 

I definitely want to do this!

 

If you do it right, which you have, you should trust yoir work

 

I had three year old twins "helping" me at times. It was a fun project though, when these die the next bar is gonna go BIG! Technology will be even better in a year or two so... I just like that the output is high and amps are low.

 

Subbed! BTW OP what's the Capacitor for going into the driver?

 

It absorbs voltage spikes & drops. LEDs don't like them at all. Also stores energy for startup. Depending on power wire lenght, there might be enough of a voltage drop to damage the driver. It's more of a "just in case" thing, plus they are real cheap and the manufacture recommend them so I went with them. Ran the lights for about two hours this past weekend(truck was sitting still) and the cooling fins hardly got warm. I would go with smaller fins next time. Hope this helps...

Don't know about the Zombie light switch....at that lumen it should be a Vampire switch! Blade would kill to have a similiar setup.

 

lol nice man been there done this tho lol i built high power led floods for my carp boat.

 

Were gonna be doing this too for my car club at college and we are planing on building a 40+ inch bar! We are planning on using it for night racing on the ice up in northern wisconsin.

would it be possible to use this driver to power multiple leds? Since it is rated to 5 amps constant current, I would like to run one of these for every 4 or 5 leds. Any feedback such as how to wire them would help. Thanks

 

This is so awesome Homemade LED light bar. Thanks for sharing.
