What over 7 months on a keychain looks like Big Smile

This is my general complaint with aluminum. You can get a nice surface treatment on there. It will look pretty when new. The underlying metal will still be aluminum. Let it bounce around a hot pocket with coins, keys, etc. and this is what usually happens. Some people don’t mind but it bugs me. So I try to take steps to avoid the tumbler action with my aluminum lights.

Actually sofirn change SP10 V2 to SP10S by using LH351D 5000K 90CRI, and same UI.

This is great news, need more flashlight models with emitters LH351D !!! I think many will be interested in the LH351D 4000K 90CRI and maybe even 3000K. Good to have a choice. I use TIR – optics in my Sofirn SP10b, maybe a Sofirn will also sell such an option?

Yes, I am want 3000K too. Hope, Sorfin will done it.

Once the C01 is running, the LED just keeps converting electrons in photons with much lower voltages (down to an OCV of 0.2-0.3 Volt), although the output is just much less bright (“moonlight mode”). This means that once you turn off your C01 and the cell voltage has decreased below 0.8V or so, the C01 will not light up again. However, with alkaline cells if you let the cells rest, the voltage of the cells will slowly rise up again. With alkaline cells you can even see this happening when measuring with a DMM. So, wait and after a while you can then turn on your C01 again. No need to keep it on continuously. The same is also true for lithium primaries to some extend, although it takes much more time for the cells to rise up in voltage again.

I guess I should have searched for this before doing my own testing, but here it is. I put a 1.5 ish Volt alkileak cell in a C01 (neutral white output) yesterday. When I got home today, it was much dimmer. After taking the cell out, I measured 0.55V. A bit later I created a setup to measure the voltage and current out of the cell into my C01 with gravity, some props and a bit of tape. After running with this measurement setup for over an hour, the light seems to have stabilized (for now) by drawing about 6.5mA from the cell. The cell voltage is down around 0.3V. When my DVM measuring voltage shuts off the display, the light from the C01 flickers as the lead going to my DVM measuring current touches it, so it slightly disturbs the setup. After one such event the voltage of the cell is up to 0.39V and stable, with still 6.6mA of current. I’ll let it run overnight to see if its still running tomorrow. It been almost 2 hours since I started the test back up, with the cell at 1.0V or less the whole time. Certainly a vampire light if I’ve seen one.

Update 1:
good morning. 9h40m since I started this run, my 5000K C01 is still putting light out. 0.24V on the cell, 4.5mA being delivered, and the brightness is about the same, (slightly brighter) than moonlight on my Manker E01. I never imagined it would run all my sleeping hours on a cell down to 0.4V already.

Update 2:
Nighttime: 25h since the CO1 drained this cell below 0.6V, and started it on again. Still at 5mA level, I have seen the voltage as low as 0.24V, but typically its at 0.35V. Right now its at 0.4V and 5mA. How many more days like this? The light output is brighter than my Manker E01 on moonlight mode, maybe 3-4x lumens. Noticeably brighter.

Amazing.
Thanks for reviving thread with this interesting data. I always run Eneloops/Duraloops in my lights, which is not recommended for this experiment. It could damage the battery.

But I need to find some dead low voltage alkalines laying around the house (that I am ready to throw away) and try this in one of my C01’s.

This is great to know during a power outage that I can use any old dead battery laying around and still have some useful light! Think of how many alkalines we throw away when they decline to about only 1.0 volts!

Vampire!

The lighter the brighter the better.

But first try to sort out the almost-dead batteries from the really-really-dead batteries.
Just in case your family has to survive whatever disaster that’s waiting for you in the pitch dark.

You are a flashaholic if you are forced to come out of the closet, to make room for more flashlights.

It just keeps going, it was still running this morning, 34 hours into this test, which started with a depleted battery. As I mentioned, my setup is a bit rickety, and this morning one of the leads moved a tad and the light went out. Eventually I realized this and tweaked it back into position. It came on and after a few seconds the battery was at 0.75V and delivering 14mA to the light, so presently it fairly bright. And the test keeps going . . .

I was hoping I would see where the light turned back on (if it would on its own). Maybe sometime later during the test.

48 hour update. After the bumbling in my last post, I decided to just put the battery in the light and let it run. It seems like the cell continued to deliver about 5mA at whatever voltage it is. The pic above shows my Thrunite Ti-3 on the left, Sofirn C01 in the middle, and Manker E01 on the right. 48 hours after the battery was spent, the C01 is still brighter than my Manker E01, but not as bright as my Ti-3.

Thanks for posting this. We are on the edge of our seats…..

I know people will laugh at this low level of light, but it is actually plenty to navigate around a dark house without falling or bumping a toe, and has the even more important advantage of not waking a sleeping spouse or baby.

The lighter the brighter the better.

R.I.P. It was still lit when I went to bed, 74 hours, albeit close to the output of the manner e01. Just to clarify, the LED is producting light still, but you can barely see the illumination looking at the LED in a dark room. Its no longer useful. But it would be interesting to see what level of current (and voltage from the cell). I’m away from home, so another day.

Glad some folks are interested, it’s sort of fun to see the realm of possible

I don’t know how many people still want C01 with this new 5mm HCRI led

The 5mm led has two options 3400K and 5800K. The body color of C01 can be Black, Red, Blue, DesertTan, Green, Orange, Bare-Aluminum

Maybe it can be 5000pcs in total.

I’d be interested in another 3400K, but even more interested in some hosts and drivers if you do another batch.

I do not think you can find interest on BLF for another 5000 pieces Barry, it is just way too many, maybe 2000 but not 5000.
But that said, the concept of an unbreakable 1xAAA light with good quality 5mm led for just a few dollars will not easy grow old, they will keep selling for many years, not just via BLF. So a batch of 5000 still sounds good.
I’m in for a couple of desert tan ones in 3400K.

And as a reminder, as said above and in the host thread, it would be nice if a few hundred C01’s will be made as a host: with driver but without led and without potting compound. Is that still a possibility for Sofirn?

I would be in for some of those, my friends have kids that want lights and this is the perfect gift for them to start playing with flashlights!
And I agree with djozz, this is probably a concept of a light that will sell for years, either for “collectors” or “users”!

Fenix has recently ceased production of the E01. It was found in nearly all outdoor shops, maybe Sofirn could step in. HCRI could be marketed as natural light with extremely little power consumption using ubiquitious AAA batteries or something like that. I mean, that’s what it is. Customers just need to know :-).

Smile, you cannot kill them all.

I didn’t expect 5K interests on BLF, 2000pcs is good enough. And I just hope to bring the cost down. More quantity in one batch, lower cost it will be. Then a better price will be possible.

If the whole light with new 5mm HCRI led is ready to made, host with driver but without led will be possible too. And both No potting. Potting cost too much time to do. I believe it will tough even without potting.

Also, I think offer one tint choice will be better than two tints choices. One tint is easier for fast assembling and keep cost low.

It seems 3400K is a better choice? That will be a great comfortable beam for kids.

Apparently Fenix self is the only party that doesn’t regret the demise of the E01. Maybe it was too good. It lasted for ever and ever. But ……… every flashlight nut would buy one for his kids, and later on for his grand kids.

Yes, and I spot one advantage over the C01: There’s an o-ring between reflector compartement and LED. Not sure if it is necessary, but it helps waterproofness when not potted. SWM also had this sealing in the R01A.

Edit: @Barry, 3400K would be nice.

I agree that if one tint is chosen, that the 3400K is probably best. From the old batch, the 3200K sold out earlier than the 5600K, and the warm led sets this light apart better from the millions of ugly cold 5mm-led flashlights still sold everywhere.

Personally I’m fine with no potting in the new batch, my son’s (rough but limited) testing proved that it is pretty unbreakable even without potting. But there are a few potting enthousiasts out there who will argue that it will even be more robust with potting in place. The first batch with Yuji’s is for them then.

On another note, I can confirm from own experience that the warm C01 is perfect for children reading in bed, works very well and they are super-happy with it. Smile

3400k only is perfect but most important is getting thousands directly to Amazon and make those puppies only available with value pricing in groups such as 2 for $10, 5 for $20, 10 for $35 etc.

They only want one, fine $6.50 etc.
I’d love to be able to buy an entire group of all the colors at once.
Thanks!

I’d spent some more on more C01 if they were hard anodized… natural or olive is my personal fav.

Nice idea of offering a complete set of all available colorsI I certainly would buy a few sets, keep one set for this household and let friends and other people interested choose their favourite colour. And yes, 3400 K please.

3400K would be awesome Wink
I find me using it more than the 5?00K one! And it would be nicer for kids too!

And, in case it would be possible to get another anodizing colours, I would be opposed to it Wink
If not, black, red and blue can make me happy Big Smile

Glad to have these news about a “beloved” flashlight! Party
