Our Recommended LED Helmet Light for Mountain Bikers
The Gemini Duo LED light set is an adaptable set that can move between your bars, your helmet, or be used with the head strap as a headlight. It is wirelessly remote controlled - ideal for mountain bikers as we can attach the remote in a handy spot on the bars, or if you are already using a larger Gemini light set on your bars (see the Gemini Titan) then one remote can be used to simultaneously control all your lighting.
The Gemini Duo operates with low - medium - high - flash settings, all of which are adjustable (10 levels total) to suit your personal preference and your mountain biking ride time.
Rechargeable Lithium Ion Battery
We prefer to sell the Duo set for mountain bikers with the larger 4 cell battery pack, which will give you up to 13 hours of light on the low setting (300 lumens), on the medium setting you'll get 4 hours and 40 mins of light, and crank it up to full wattage on high (1500 lumens) and you'll get three hours of brilliant light.
The rechargeable lithium ion battery is easily attached with a velcro strap, whether you're using the light on your handlebars, helmet, or on the head strap mount.
