Gemini Lights Duo 2200 Multisport

I use this for road biking and replaced a Garmin Varia 800 (which I hated because it was dim and has miserable battery life) with this light. I put the battery for this light in a small bar bag, so I don’t have to deal with strapping it to the frame. This thing is BRIGHT! On full power, 2200 lumens feels like daylight when riding down hills. On mid power, it’s significantly brighter than the Garmin was at full power and lasts, well, I haven’t been able to ride in the dark long enough to even significantly drain the battery yet. The remote switch is brilliant (as you’ll definitely want to dim this thing when other bikers and even cars pass you). All told, this exceeds my expectations in pretty much every way. It’s well worth the money.
