Review on ETpower® Bicycle Waterproof HeadLight Lighting by Kyle Merriman

$20.99 free shipping, 2 days (main post) This light is amazing! I just used it for a 24 hour mountain bike relay race. The pattern is perfect for trail/single track - I used the brightest setting for trail and the lowest setting for dual track. I wasn't able to calculate the battery life but my laps were 1.5 hours and it never died. * charges between the circles. I was able to mount "mods" onto a helmet with some Headstrap. You may need to add an elastic band to the mount to give it some support. I like it as a light helmet - not too heavy. Just put the battery in the camelback shirt pocket. Also works great on handlebars, but may require a bungee for better protection from off-road traffic. Even if they last me a season, it's worth it. Sorry American lamp makers, but these Chinese lanterns outperform those of us on a budget.
