The Diablo Mk4, the new update to the Exposure Diablo Mk3, gives new meaning to the concept of “head light.” This helmet mounted light, which was just announced, casts up to 1,100 lumens anywhere you turn your head.
It comes with a USB charger so it can juiced up from an AC outlet or from a computer port. It looks to feature the same weatherproof construction of the previous model and can easily mount to most helmets. On full blast this one will offer about an hour’s run-time, which could be great for commuters. On a lower settting it can obviously go the distance. But for those who want to cast a lot of light for a long time, such as a 24-hour race or something, there is even an optional 3-cell external battery that can offer up to eight hours of run time.
