I have been hearing a lot more SP hub complaints lately though.
Did some night riding last night to test out the LS905. The beam pattern is noisier than the Cyo with some funny artifacts around the perimeter and some noticeable banding. But overall the pattern seems better and the cutoff even tighter.
The standlight was weirdly inconsistent - I think it might not run in “auto” mode. But I have seen reports of it being weird with the Renak hub which is also lower powered so I wonder if the problem is the 1.5W hub.
It occurred to me that it might be possible to mod the light, swapping out the switch and rewiring it to make it an on/off switch. There’s a logo on the back of the light that I suspect hides a screw hole. But honestly I don’t know if it’s worth the bother when the IQ-X isn’t that much more money.
