Sofirn C8F host. 21700 C8F Available

Hi

I have ordered a couple of Sofirn 21700 cells to try and see if they help.

Still getting nowhere with the lock ups though :frowning:

Thanks again all for taking the time to reply.

Enjoy your weekend

Did you successfully figure out how to switch from ramping to one of the other modes?

I’m still not sure how it’s done. Lol

You never explained what the lock ups where doing. Does it just stop responding or does it not register all of the clicks properly? Do you think your switch may not be making good contact or does it seem more like something in the software that is hanging up?

Ordered 2x hosts on 8/29 and it looks like maybe it was finally shipped today but the tracking is pretty vague.

I just stuck an 18650 battery in to check performance in comparison to the 21700 and measured 420 lux for the 18650 against 460 lux for the 21700. The 18650 was a decent Klarus high current one.

So there is a bit of difference. Both batteries were fully charged.

Hi,

With the light on and in ramping mode try clicking the side button 4 times on quick succession - the light should blink 2 times indicating that it has switched back in to Group 1.

Regarding lock ups I’m not sure if it is the side switch not responding or the light just “crashes” but for example when clicking between levels (not groups) I have had the light go Low > click > Medium > click > High > click > Low > click > Medium > click - nothing still in Medium > click - still nothing, still in Medium > click and hold - sometimes the light stays on other times it goes off. Then I pull the battery to start again.

Hopefully, the new cells might help shrugs - fingers crossed :slight_smile:

Thanks again,

Moley

Hmmm, I don’t think the battery is going to have any effect on the switch.

It’s possible the switch may not be making good contact internally or the rubber cover is not centered. I’m not really sure. You could try unscrewing the bezel on the switch and removing the rubber cover then push on the metal switch directly and see if it still does it.

There is another way to test it by bypassing the switch, but I don’t know how familiar you are with electronics.

Hi Jason,

I know what you mean about the batteries but you never know.

I don’t really want to start pulling the light apart as it kinda works at the moment and I would probably kill it completely if I were to start fiddling too much :slight_smile:

Given the number of Sofirn lights that I already have that work absolutely fine and the bargain price that they are, to get one that is a bit faulty isn’t really the end of the world I guess - just a little disappointing.

All the best,

Moley

You can still contact Sofirn about a warranty. They may ask you to make a video showing the problem. Some companies do that. See what they say. You shouldn’t just accept a faulty light.


Door to door 8/25 - 9/22. Magnifique!

If you get it in September, that’ll be pretty good.

Once it gets the “processed through…” part, it’s pretty much incommunicado ’til you’ll get the “arrived ISC Los Angeles” email or whatever. Could be a week, could be three.

What do you think Sofirn could actually do? Pretty much nothing. You can call your local post office if you want.

My packages from China typically take two to three weeks. Occasionally it may take up to 2 months. Once it gets to the US it moves pretty fast.

Thank you Lightbringer and JasonWW. That both answers my question, and gives me confidence that this advanced technology will be in my possession soon enough. :beer: :+1:

Exactly. My new 21700 host is on the way to Mars via Theiranus and will probably be here sometime next millenium. :wink:

My friend in Dubai sent me a package today that will be here Wednesday. Go figure.

:smiley: Thanks to Dale

Like he said, once it hits “snailmail” it moves pretty fast, but it’s the barge coasting across the ocean that takes most of the time. That, and sitting on the docks in a cargo container, being packed/unpacked, etc.

I once ordered 2 lights from Sofirn within a day or so. First one must’ve just caught the tail end of the still-got-room barge and I got that pretty quickly, but the second one missed the boat, literally, and took a month or more.

“Regular shipments” across the ocean are pretty much “whenever the barge gets filled”. Neither Sofirn nor the USPS have any control over that. Talk to Maersk or whoever. :smiley:

Very helpful feedback :+1: :smiley:

@Sofirn any plane for single led 21700 c8 ? If so please re-design the head the old c8 style is boring.

They probably want to see if this new battery size sells well.

Do you like the 21700 and think it’s here to stay?

I could be wrong don’t think this stuff is going by sea. It may be sitting around waiting for an air container that has an extra few cubic inches at a reduced rate though. Or getting routed through various countries in order to arbitrage international post agreements.

Thank you eas :smiley: :+1:
