Just did a real runtime test on 0.3% mode. It’s something that is hard to extrapolate from current measurements because the current is so low. And it’s annoying to test with a 5Ah cell because of the run duration. Anyway, it started its low battery flash this afternoon and it’s been running since the 22nd.
Runtime: 3 weeks, 4 days
LED: 2700k
Cell: Samsung 50e - I see between 4850 and 4950 mAh from these with low loads.
I have no complaints considering how practical three moonlight level high-cri emitters are. This really is a no-frills workhorse light.
