I have a 12w HID, and also about 30 watts of halogen light.
The HID is fine.
The halogen light is MUCH better.
Either one is well out of the LED league. LED's are, today, nice for flashy's, but are not at parity with other solutions. I'm not sure why this is at issue. It's pretty obvious, once you get on the trail. I had an LED guy stop me just last night (the brightest one I'd ever seen - El500?) and ask, what is your light? I WANT one.
