Small ain't no thing to the engineering geniuses at Lezyne. Not only were they able to jam some serious brightness into the compact Lezyne Femto Light Pair, they kept the lights' stylish appearance up to the company's usual standards, too. The Femtos' durable CNC machined aluminum bodies are weather resistant, dissipate heat to protect the battery, and won't rust no matter how long you leave them outside. The lights' lens double as their onoff button for a super clean, button free look. You can use the lens to cycle through four flash modes and one steady mode, as well. The Composite Matrix back plate can be unscrewed to replace the two CR2032 batteries, and the multi position silicon rubber strap can be moved to angle the headlight up or down. The Femto front light provides 15 lumens of light, while the rear cranks out 7, to make you more visible in traffic. Both the front and rear lights can last up to 60 hours on one pair of batteries. The Lezyne Femto Drive Light Pair comes in the color schemes Blackred, Polishhi gloss, and Blackhi gloss, and each light in the pair ways approximately 22 grams.
