I like the tint on my new Sofrin sp40 (warm 3000k?) better than the Skillhunt H04 (nuetral white 5k?). Still trying to figure out the UI on the Sofrin.

The Convoy S2 is not as warm as my old Yinding bikelight so I think I will only use it as a backup. The S2 is a great light for the price but I have not tested it on the bike, It also has a bit less flood than the Sofrin so it would be better as a headlight than bar mounted IMO. Your setup with the Convoy on the helmet and SP40 on the bars is exactly what I would do with those two lights.

I will probably use the Sofrin SP40 on my head as it throws a bit more than the Skillhunt HO4 which has the TIR refactor lens. I Should have got the smooth lense for more throw, oh well, my old Skillhunt HO3 was my fav EDC before I left in the middle of a highway).

My next test will be to see which lights work best for hitting singletrack on the fatbike, not sure which one works best in the snow. I used the Yindig for the last three years and have no complaints but do not always need the runtime of a heavy 4x18650 setup and want to try some new budget 1X18650 lights.

Thermal stepdown on the compact headlights limits the usefullness of them for long downhills, I need a steady 750 lumins on both the bars and helmet for that. Winter riding extends the usefullness of the turbo/high modes on these little lights.

What I would like is a bluetooth remote control on the bars that cycles through the modes on the bar and helmet lights and also shows battery life.
