Got word back that the at the end of battery life, the headlamp getting really really hot and then just shutting off and not stepping down at the end was a defective headlamp.
All of the batteries are brand new.
I'd say thinking about it. It's probably not too big a deal of it dimming down as it's still bright enough and I get longer run time. The run time on high is 3 hours.
Something else I noticed. Is when the battery is about dead. The light is supposed to step...
Why would Zebralight say H1 will run for 2 hours if it's going to step down in 45 seconds? Sounds like false advertising. They should put H1 will run for 45 seconds then step down, etc.
I did read there being a problem with these new H600 models early in their release that they ended up having...
I'm going to have to test it again. I had the light sitting off on a table while I did other things. And I didn't notice a drop in output before it shut off. Just noticed it shut off suddenly. But I'll test it again a few times. Will probably partially charge a battery to test so I don't have to...
2-3 seconds. Then it starts stepping down. I counted around 11 steps. It steps down when in H1 870 or H2 560. So the light won't run in 870 or 560. So I'd say max lumens the light will run is around 400 or so.
Batteries I'm using are unprotected Panasonic NCR18650B. And protected Orbtronic...
Are there instructions somewhere on how to replace the lens on these?
I was looking at getting an H603d flood, and I've read the quad LED's on that can shine a cross artifact when looking at walls, etc. And so I thought if I found that to be annoying that I might could put a frosted lens on it.
I just got the Zebralight H600Fd III.
Here's the output on High:
High: H1 870 Lm (PID, approx 2 hr) or H2 560 Lm (PID, approx 2.5 hrs) / 255 Lm (3.9 hrs) / 117 Lm (11 hrs)
When I first turn the light on High. When in H1 870 or H2 560. After a few seconds, the light starts stepping down...
I was comparing the "new" 3500 10A 18650 with the 3400 that is commonly used. Was keeping an eye out for the 3600, but that never got back in stock. I'm guessing the 3600 is similar to the 3400.
My understanding is the new 3500 has a safer chemistry and the commonly used 3400 type 18650.
