BT40s on the bars and matching Convoy S3 XM-L2 4c torch worked fantastic in the forest last night. Riding mate has the ultimate combo of Exposure 6-pack and Diablo and I wasn’t under lit and didn’t suffer from shadowing when I was in front like I got previously with my warm white SSX2 and torch combo.
My neutral white LEDs were noticeably yellower but were certainly bright enough with fantastic definition and lasted the 4hrs ride no problem. (Only used the lid torch on twisty stuff so a single decent Panny 18650 lasted fine)
BT40s is a great floody bar light, but limited throw so no use on helmet. Build quality is great and it comes with decent battery and charger. Add some Gearbest gopro mounts and the Convoy torch and it’s a great well made set for under £50 delivered.
