Dola Quick calculation: in the spec: battery is 1,8Ah, at in HIGH mode it last for 6 hours, so 1,8Ah*3,7V devided with 6h=1,1W! 1W LED can procuse max 100LM, so the real LM about 110LM :(. Also, Vladm wrote as comment: „not brighter than my stock 100LM light”. Another approach: Anderas wrote it last for 2 hours in high mode, so assuming the battery is really 1.8Ah, it means 3,3W power, so max 330LM light. Math can’t cheat, something is wrong! It looks nice, but it's seems a weak lamp. In my opinion, evening cycling requires 3-7 Watts of real power, which means real 200-600 LM. Would anyone measure the real power (in Watt)?
