I bought the Auxito 20,000 lumen version. Fit was perfect. The headlight brightness is amazing now. Its a wider and longer beam. I can see much further down the road and light is absolutely white in color with no unusual blue tinting or anything. So far, so good. It comes with a 1-year warranty so if it blows in the next year, I'll get it replaced. Another rider here in my area has had these on his bike now for a while and he said the durability is good.
