Mark, can you please post a pic for us, showing what is this “routing the strap”? My next zebra is H600w IV, just waiting to come back in stock.
You told it everywhere. But what you want to say?
That mk4 have no issues? It have. ZL reply
“1) We are aware of the high current through the spring, and that’s the exactly why we switched to multiple pins in our flashlight products. High output headlamp models will move to the pin design in the future. Different spring materials or bypass won’t help much because some of our customers will still insist on using their low quality high resistance protected batteries.
2) We are aware of the ringing/oscillating in the Mk 4 18650 lights. We’ll try to fine tune the PID parameters (and possibly setting up a new calibration process) in future. “
Yes those issues usually have small effect on users.
But it must be fixed, isn't it?
I am looking at the H600Fc, but does anyone know if Zebralight has addressed/fixed the oscillating PID and the issue with the spring in the tailcap mentioned in this thread?
Any news?I recently got the H600Fd Mk IV after a bit of a backorder wait and so far I'm not favorably impressed. My light dims itself down significantly from high after 25 minutes from a fully charged battery. It doesn't like to operate on high when the battery is under 4 volts and dims almost immediately. I have a previous model in the series and it doesn't present with that issue so I wonder if the higher output is a setback. Coorespondances with the manufacturer seems to circle back to "cool it down" but if that is a requirement of use then it's not a useful tool to me. Sending it back for diagnosis.
Thanks for the tip but I'm stumpedStefano, the H604c is high CRI and warmest LED. That combination = hottest led per lumen produced. So isn't this behavior what one would expect between those lights?
Yes, I have tried both the reset and to raise the PID.Sorry, just read that you did attempt a pid adjustment.
Without any change from pid, its function could be bad.
Either programming or components.
From an old post but wondering if anyone has a link for a better holder (Armytek?) than the silicone holder that ZL ships with it's lights? I'm looking to upgrade to a H604c from my old ZL (can't even remember the model... long discontinued) and I never loved the silicone holder as it would slip if I was running or bouncing around.ank - it's not terrible, but the Armytek plastic holder fits perfectly and I would recommend it over ZL's without hesitation.
Zebralight wrote to me to clean the contacts, if this does not solve the problem send to China for repair.
I cleaned the contacts, waited a day or two to be sure of drying and repeated the test.
Everything remained as before, the H604c drops in brightness too soon compared to the H604d
After a few days I was about to pack the headlamp for shipping, even though the hot version was marked with an orange string (to recognize it) I wanted to check that it was the "c" version with the PID problem.
I realized that it no longer works, it does not turn on, it is the first Zebralight that "dies
I also hope it's just a bad specimen.Maybe you just got the rare "bad" one? I hope so (for my sake) as I'm getting ready to order the same one you have...
