I try to convince people to buy the brightest lights they can possibly buy...and more than one of each There is absolutely nothing wrong with halogen. If it is brighter than LED and cheaper what's wrong with it? I'm not here to push technology just because "it's sexy". If technology is useful, I'll embrace it. SIS, STI shifters, threadless headsets, external bearings, suspension forks, etc. I've tried and found to be an worthwhile improvement over the existing technologies.

I've tried LED (several times) and I'm less than impressed. The light is has the wrong color rendition, I have no use or need for flashing, different power levels, etc. If I'm going to carry the light, I want it to be on...full...for as long as I need it. If I need less light (or longer run time), I can turn one of the lamps off or add a lower wattage bulb. I won't buy a commercial system because you pay through the nose for a light that doesn't have the output of an "outdated" halogen system. A Niterider Trail Rat puts out what most commercial LEDs do and way better than many for less money. My DIY halogen puts out more light than anything else I've seen...including most car lights.

I've even tried the P7 (it doesn't have 900 lumens output). Nice light if you only need it for about an hour on high. But I can get the same output as the high beam for a similar price with halogen and get 2 to 3 hrs run time. And, like many LED, it's too directional. I've had too many people pull out in front of me while running LED of various kinds for my taste. The second time it happened, I checked the light for myself and for anything outside of a fairly narrow band, the light is dark to the side.

I'll continue to push halogen, not because I'm a luddite but because I consider it to be the best bang for the buck currently available.
