The Gemini Lights Xera LED 850 Lumen 2 Cell Light System is powerful, lightweight, versatile and affordable. With an output of 850 lumens, you can be sure the XERA LED Light System will shine your pants off. The top-of-the-line CREE XM-L emitter is currently the top contender for maximum efficiency and brightness delivered in a small package. The Xera weighs just 52g. It's tiny and extremely powerful. Fit for races and fit for you. The lumens are measured in an integrating sphere (very expensive piece of equipment) in CREE's labs. It's fairly common for manufacturer's to state claimed lumens over their actual output. We believe in honest out-the-front lumens. In light reviews, we're consistently praised for this. No longer do you have to settle for decisions made for you. Set your mode sequence and brightness settings on-the-fly at the touch of a button. Whichever mode, whatever brightness level, it's entirely up to you and we leave it in your hands. And for those wishing not to twiddle with settings, don't worry. Out-of-the-box your light comes with default High, Medium and Low settings for you. The XERA LED light also includes a factory reset function. With the Xera LED Light System, we've left nothing out. Experience night skiing, running and mountain biking all in the dark. Xera is helmet mountable, bar mountable and even includes a comfortable head belt mount. The complete system can be carried on the head leaving no dangling wires to your camelbak. The same essential features from the Gemini ethos exist on the XERA such as battery indication, overheat and overcharge protection. We took care of the complexities so you can have the best, worry-free experience.
