7W COB with 6 degree lens. 540 Lumens. Runs off 4x 18650 2.4AH cells for approx 5 hours runtime (700ma buck).
Should work nicely with a spotty helmet light

Great light. I haven't seen those chips before.
What driver/battery pack are you using?
Looks like a nice fit for a Hammond case.Posted 1 year ago # -
7w COB/lens/heat sink from LED-TECH.DE along with a 700ma buck from the same place.
Battery pack is 4 18650s with a 4 cell holder but anything 12v+ will do.
