Most of the LED conversions usually couldn't compete with a good H4 upgrade. They use them on the Hummers and MRAPs over here, they look bright from the outside loking in, but I haven't sat in one at night yet so it's hard to see how good the pattern would be for driving. I'd like to see a side-by-side comparison, but kinda cool though. Wonder how spendy they are?
Expect the output to be on par with this 10" Ridgid light, however it may be less due the type of lens not being as clear as this bar. For $400, I would just get a Ridgid bar that you could transfer to any other truck down the road.
