The Lars Rover Power 850 is a USB rechargeable headlight with a powerful lithium-ion battery and a darkness destroying, 850 lumen, CREE LED bulb. Equipped with a power meter on board, so you can see just how much charge you've got, the Lars Rover Power 850 will never leave you in the dark.

Its precision reflector provides superior luminous guidance for up to 10 hours of ride time. The Lars Rover will run for an additional 15 minutes in low power safety mode after the low battery indicator light comes on. The rugged alloy construction is weatherproof and strong enough to handle the abuse of an urban commute.

Supported by the Mission Control III mounting bracket the Lars Rover Power 850 will never come loose or bounce about on rough terrain.

Strong light that lasts all day and all night

Most of my experience with this light is as a daytime safety device to let motorists know I'm sharing the road with them. It's great for that purpose. It runs for 10 hours or more on a single charge in flashing mode, and I've had other riders comment they can see me from a very long distance away. I've used it a bit at dusk and during the night, where it's very bright. It has something like five settings, but it remember the previous setting when you turn it off and goes straight back to that when you turn it back on. Charging time is quite lengthy, but the payoff is very long run time. The quick-release is handy as well. The Lars Rover can also use the quick-release sold with some other brands (like Planet Bike), although the Lars Rover mount is slightly wider. The light doesn't get hot and seems very solidly built. If it fell off my handlebar (like my Planet Bike did on a really bad road), I'm sure it would survive just fine.
