Yes - this looks to be a great light. However, your test photos appear to confirm that falls far short of a three-watt light. The Dinotte was way brighter -yes?

And I guess the price is good too - considering the battery being on board. But again, what is the "life" if repeated run till failure? This looks like it could be a "need a new one" every year light..... can you replace the battery(s)...?
