The last time I bought a light for my bike was around 2003. It was clunky, and the battery was unbelievably finicky. The charging process required a master’s degree in physics. All of this, and the thing barely put out any light.
So much to my surprise, then, when I clicked on a Sigma Karma Evo light, I could see for miles and miles and miles. Well, that’s just a lie. I could, however, see much further than I thought possible from the seat of my bike.
We received this light when I was too busy to get out on a night time bike ride. Then I finally got the chance to use it, but it was in a box for a month. So I thought I would top off the charge, and was frustrated that the indicator light wouldn’t come on. Checking the troubling shooting info, I figured out that it was too full to be charged. The battery hadn’t lost any charge, even after four weeks.
A strong battery is great, but the light’s performance is obviously the real deal maker-or-breaker. This incredibly light unit puts out an amazing beam, offering up to 320 lumens from its small, watertight, aluminum housing. Sigma includes a helmet mount, battery, and charger in the set. That’s already enough to impress, but consider its burn time of four to twenty four hours, and it should seal the deal.
