Thanks. It’s interesting about the shadows when using a bar light with the helmet light. I’ve noticed that too. Makes a big difference in in depth perception and judging the roughness of the terrain. My setup is currently: 2300 lumen (Wiz XP3 on the helmet) and I occasionally use a bar light, 850 lm USB style light (L&M Urban 850). The latter has limited battery life at full blast (1.5 hr). Wondering if more light on the bar would be better. So far it’s a decent setup.
