Sofirn C01S SST-20 4.000K 95CRI / Low-High version available again!

Are there any more coming into stock soon with “BLF” engraved?

Is it just the unanodised version that has “BLF” engraved on it (as opposed to “Sofirn”)?

The original no-ano run had “BLF” printed on it, while the later had “Sofirn” printed on it. I’m fairly sure the BLF print wasn’t, and won’t be continued

Yes, and the later no-ano version was sandblasted, so the BLF edition remains unique. Or is the sandblasted version unique? I’ve read that this finishing was done by accident, not ordered by Sofirn.

Cheers to you both.

I need some guidance. My son still hasn’t learned to check the pockets before putting clothes in the washing machine, and one of my C01Ss took a bath. Now it will only come on on Low. I opened it up and cleaned the contacts, and put in a fresh EBL NiMH cell, but no change. Is there anything I can try to see if I can get the High mode back?

I just tested it again, doing several twist-on, twist-off cycles. It did come on on High once out of a half dozen attempts, which says to me that it might just be moisture causing the problem. I am going to take the head completely off and the cell out and leave it overnight to see if it makes any difference.

Put it a bag of rice like people do with wet cellphones, it will pull moisture. you can use an pair of stockings to hold the rice and put both in gallon zip lock for a few days.

ReFrigerator is low humidity.

What are the changes / improvement (?) of Sofirn C01S from its predecessor C01? The latter is only about US$6, whereas the former is now selling for about US$9 in Sinigapore’s Shopee and Lazada websites.

They are two completely different flashlights.

The C01 is a low power flashlight with 5 mm LED without lens or reflector and a single mode.

The C01S is a high(er) power flashlight, SMD LED, TIR lens, and two to three modes.

Do c01s already have three mode? I thought only c01r got 3 mode.

c01 is one mode, 3200k High CRI 5mm LED, 7 lumen single mode
c01s is two mode low high, no memory, 4000k sst-20
c01r is 3 mode red 660nm

afaik c01 series is discontinued… buy what there is, dont expect another batch…

Might need to get additional c01s. Potted is green and black only right?

The non-ano silver C01S is not in stock for some time

80 PCS Small Magnets, 5x3mm Mini Magnets Round, Tiny Magnets Small Magnets for Crafts, Strong Office Magnets for Whiteboard, Fridge, Home, Kitchen, Office Amazon.com would these be good?

Those are the right size. The strength and quality of the neodymium magnets can vary a good bit from my experience with them.

There is a 5×5 size would that have more sticking power even with the same surface area for sticking?

If you don’t mind that it protrudes about 2mm past the end of the slot of the CO1S

Edit - I would stick with the 5×3mm, even the weak ones had just enough strength to hold the CO1S on a vertical surface.

some of mine

Convoy actually has 5mm diameter x 3mm thick magnets on their Aliexpress store. He advertises them as temporary buttons for flat top batteries, so strength might not have been a priority in sourcing them, but Simon generally sells quality stuff, so I’d personally try his magnets versus a random Amazon seller.

So I’m not the best at physics but that would be the ultimate test right? It would be easier for them to hang upside down?
