If we include loss of efficiency in the circuit, 1,7h seems perfectly normal for a 2,35Wh 16340, since the LED will draw around 1,00W.
On the other hand, if the LED draws 2W for 200 lumens, the light should only be able to run for 1,15h, at best. That means the brightness will step down at one point.
Maybe.
But it seems to me that the circuit should not have so many losses, otherwise the moonlight was not so long. I just compare with other runtimes of flashlights.
Also i sure here step-down on turbo which is not listed in the specifications.
Any 219 versions of the E02? I even tried all 3 colors, got ” the combination you selected is unavailable” or somesuch.
I wanted to get a couple, but I really don’t want those any of those hateful little G3s. I have to slap on like 3 layers of diffusion film to mask the ugly ugly beams that G3s make in reflector lights.
After some searching I found reference to “Manker upgraded driver, UI, switch…”
The UI has definitely changed, Turbo has moved to the blinky mode group. And it no longer allows you to choose 1,2,3 for each level. Can only configure moonlight level.
OLD:
NEW:
As for driver and switch upgrade, I can find no extra details. But indeed there were many reports of unreliability in 2016 so perhaps the changes were warranted ?
The ‘upgraded version’ is not actually new, it appeared in 2018 best I can tell from wayback.
I received my CW E03H that was 1/2 price on clearance from Manker and it has the new mode sequence listed above - same a the Folomov “wave” mode sequence, which I don’t like.
I prefer the sequence to go to low from turbo, rather than going to high from turbo.
The headband can’t hold the light stable - the light bounces when I walk.
The diffuser does glare down into my eyes and glasses - might be reduced by applying black marker to the bottom edge.
I like the beam pattern.
The CRI appears to be adequate for EDC use.
It seems heavier than a AA headlamp needs to be, but it might survive being ran over by a tank.
I received my E02 and E03. Both seems OK.
E02 came in retail package, E03 has a simple cardboard box.
The E04 clip is a trash. Diffrent than advertised and not fits to the groove well. It tends to pop out. Simply not designed to this light. I wrote the seller asking for a good one.
The E02 clip is original and fits perfectly.
