I learned about the FL1 certification. Cool stuff.
That being said, I'm still not shelling out $250 for lights. I'm still running my Amazon cheapie set that I paid about $50 for combined. One bar light, and one helmet light. Do they have verified lumens? No. Are they bright enough to safely light the trail? Yes. Are they water proof? Mostly. Lost one of 3 (2 bike set up). Do they last for hours? Actually, they do.
I've been on numerous group rides with folks that have paid a lot for lights and frankly, I can't tell the difference between a $200 bar light and my $25 bar light. The technology is pretty developed these days and while the name brand lights might give you a couple more options or a display, in the end, they both throw light. Is the name brand better? Maybe. Is it 4 or 5 times better? No.
