I received and installed mine today. 3 business days to ship, pretty quick. I wasn't impressed with the overall quality of the product upon receipt. I also found that the lumen ratings were very misleading. Their website states 2000 lumens low beam and 2600 high beam. The box states 2200 lumens low beam and no rating for high beam... but has a total range of 2200-2400 lumens. Not sure which rating is accurate?
Also, what Yoda mentioned about high beam vs low beam difference is exactly what I am experiencing as well. The difference is so small, yet noticeable, but it might as well not even be there.
As far as total light output goes, these are incredible. Very bright... but the downside is that they have crappy distance. It seems that the light isn't focused enough to illuminate what's ahead. It does a good job of lighting up road signs, but I assume that's due to scattered light. These are no doubt an improvement over halogen, but I am still debating whether I should keep these. Hope this helps anybody who is looking into this.
