Check out IPF. I have a pair and I find them very nice. Especially for the price.

 

I live in deer/elk country...not a matter of if but when there going to get hit..., So i run the cheepie farm tractor lights 130 watts (about 15bucks each) when I paint them black you couldnt tell there not any of the big name lights and when there turned on at night my truck side by side anything other than light force cant tell the differance....

 

IPF 968 ...much better than the hella 500's.. a few bucks more obviously but not much. they give a driving and spread pattern

I'm running a set of KC Slimlite with the "driving light" set up. They are awesome. Give me a nearly perfect rectangular beam that lights up the fire roads great. With them lined up with my highs, I keep the lows on and can see everything. I love it.

My only gripe is the lights took me a week to install them because the relay was wired wrong. Caused me to blow fuses as soon as I flipped the switch.

 

I've got some Hella 500s with 100w bulbs, they are ok. Nothing to write home about imo.

My cousin has some Deltas on his TJ, they are really bright.

 

I am really digging the lightforces but for now i will settle with hella500s till the time comes where i NEED the better light source.
