I ended up finding one on amazon that is stupid cheap if it actually performs 80% of what it claims. I’m gonna give that a shot. The problem I’m running into is that lumens are so general of a measurement, and that one 500 lumen might might be great and then another 500 lumen light barely lights up the road. Lumens tells you nothing about beam pattern(if there even is one) and people seem to claim whatever they want for lumen output. In any case, I’m a huge fan of the lux measurement, and I think I’ll just fork over the cash for a Busch and Müller if this amazon cheapo doesn’t do the trick. I have a B&M on my touring/commuting bike and my friend has one. I know they make Fantastic lights, and use the lux system and very directed beam patterns, so you actually have an idea of light on the road versus just a blast of light out into the world of some random number of lumens. I’m also not looking to blind oncoming traffic.

It does say it’s rated for 6-80v. I’m thinking the 100lux rating is probably just at 80v. I guess I’ll find out soon.

That’s what I was thinking, regarding the cutoff optics. On the one picture diagram it looks like it might actually have some thought put into it. And I think it’s an aluminum housing too. I’m not expecting much at this price, so it with either meet my expectations or be a very surprisingly decent light. At this price, the best value on the market if the optics are good and it performs half as well as claimed.

Awesome with the switch wiring. I’m definitely using that. Thanks!
