Review on LEZYNE Hecto Drive 500XL Bike Headlight – Powerful 500 Lumens Daytime Flash, Long 20H Runtime, USB Rechargeable, 8 Modes, Compact & Durable LED Front Bicycle Light by Sameer Hilton

I like the small design, but I was concerned about a lithium battery product that does not clearly indicate the battery power. His price suggests he should work and work, as he says. It's not cheap. I have charged and run this on several trips. I typically use the lowest settings on most bike lights to reduce glare to other riders. The lowest setting (20 hours) is acceptable but not ideal. Regardless, I can't get close to 20 hours of use, half of it. On the second lowest setting, which is minimal but good for me, I drained the battery again in about an hour - not nearly as listed online. I'm sorry, Lesine, but I have to go back.
