Leyzene tends to pride themselves on the ultra-design execution of their products, so I was interested w their light offerings. I got one of their XL series lights, mostly because it takes a non-proprietary battery. So if your light starts to dim, throw another in. Most systems require you hustle home quickly if that happens, but I just have to carry a relatively small extra battery in the caddy they provide, and I am set!
All well and good, but a couple of immediate hiccups: the batteries provided must be from a bad batch -one wouldn't take a charge, and the other only a partial (and I metered and charged w various source methods when the first wouldn't take). Bummer, because I called both BC, and sister-site Competitive Cyclist to see if they had the newer versions shown at last year's interbike show. No one could give me a specific answer, but if you look at the copy photo -they are the newer versions (w a spring behind the battery for better performance). The pictures here show a silver and black option, but the silver pic is actually the Super Drive. Okay, batteries suck, 2400 maH too (could be higher capacity for the price, availability!). So I have sent them back, and have yet to receive new ones!!! They were apologetic, yes, but confirming bad batts was like pulling teeth. I had to put one of my own 18650 battery in just to test the light! Anyway, nice beam, button bit hard to push (if on bike this would present a problem) between the modes. I have 502b flashlights that are almost identical in architecture, and the mode switching is MUCH better. The 'Loaded' kit comes with that awesome extra battery, helmet mount, and an extra bar mount w/o cinch bolt -now that's just cutting too many corners. The threading for the cap is so fine, that taking it on and off is a skill all its own. Cross-threading could become a problem if not careful. So, all added up: Leyzene did not live up to its ultra-design self-title. This is its 2nd gen of these lights also!
