However, the road/gravel version runs two spots, one flood, the trail two floods, one spot. ![]() therefore, more efficient cooling.īoth systems use CREE diodes and carry two-year warranties. An internal heat sink (or thermal core) permits weight savings, while also reducing thermal junctions. The casings are 3D printed in house, which allows rapid changes in production run. However, I'm assured they've a ten-year lifespan, which works out seriously cheap, in the longer term. First up, unlike something like Exposure Revo MK1 dynano light (one that I've run for seven years and am extremely fond of) these are completely sealed, in the fit n' forget sense. ![]() Hold onto your bars, there's no corners cut when it comes to materials and technology.
