Call me crazy but I ordered 5x2.5mm magnets, the half millimeter leaves the perfect amount of room for a dab of epoxy on the back of the magnet. Place a piece of wax paper over something magnetic and set the light on it (standing upright), that way the magnet will be at the exact right height, then leave it to dry for a few hours at least.

Where did you find 2.5 mm x 5 mm magnets? I’ve only seen them in whole number increments, not fractional.

I guess Simon from Convoy sells them in his store in AliExpress!

It does depend on the magnet though, some stick better than others. I coincidentally bought a batch (3x5mm) that makes the C01 easily stick in all positions.

As I mentioned earlier, not many are able to measure the strength of the magnetism of these magnets, so sellers get away with everything, so in good ol’ chinese tradition everything is indeed what they sell. In Europe we have supermagnete.de, not that more expensive than Fasttech or Banggood, that makes a point of actually selling what they claim, and I have never got bad magnets from them.

I spotted that tip about using wax paper and resting metal on the top so that the magnet sets flush to the end — that’s a really good idea. Wish I’d seen it earlier. Mine sits maybe 0.25 mm below the surface, but the magnet still holds pretty strongly. It’ll only work with it on raw exposed metal (painted will work, but it slips) and it will naturally pivot to put the magnet at 12 o’clock.

The magnets feel very strong, and they’re difficult to separate. So I’m convinced they’re decent quality.

I tried to dissolve the super glue with acetone, but it’s not getting in behind the magnet… so it won’t come out. I expect I’d have to drill into it to break it, then pull the pieces out.

Thanks. I don’t know how much stronger they’ll be compared to the ones I already have. Can you adhere the light to metal with the magnet positioned at 6 o’clock?

If the magnet wasn’t a tight fit there’s no need to drill it, just heat the tube up… Cyanoacrylate releases/breaks down/softens/whatever at higher temperatures.
Depending on the grade it’s strength retention drops to 50% somewhere in the neighbourhood of 80-120*C. Couple hundred degrees celsius should drop it well below 20%. Sure there’s High Temp grades out there as well but I highly doubt you used such a glue.

You should get one of the BLF-edition C01S lights, they should be available one of these days. I expect not as indestructable as the C01 (still very sturdy), but more output, low and high modes, bare aluminium without finish, and a nice BLF marking.

Djozz, thanks for the pointer.
That bare aluminum look :heart_eyes:
I am going to dress up at least one 5mm-C01 head with a bare aluminum SST20-C01-BLF body :sunglasses:
Also great Sofirn adds a BLF marking to give credit to the origin of the design.

You could carefully (gloves, eye protection, outdoors…) give your C01 a bath in lye (drain cleaner / sodium hydroxide / etc) to strip off the anodizing for a bare-aluminum finish. Just apply some petroleum jelly or something to any areas where you don’t want it intruding (threads, in the reflector area, etc) and then just clean it off after the bath.

Yeah, only problem is that I have a tritium vial installed now. That would likely not survive the heat…

Thanks for the suggestion to go with lye for removing the anodization. Already wanted to try out that to remove the anodization in the tritium slot.

We need a similar BLF edition of this fantastic AA light!

It sounds like a good idea. However, a single mode twisty seems less practical for a larger light. Another ui may not differentiate itself. Unsure how this would be implemented.

[Omega_17]

The stock UI of this light is already perfect its just the stock LED that can be greatly improve with a Luminus SST-20 95CRI and maybe a new unique color as a bonus?

[iamlucky13]

I think Omega_17 is suggesting a BLF-edition SP10 V2, not a AA version of the C01.

That could be a high CRI emitter, and possibly a different firmware. Unfortunately, Narsil or Anduril would probably require a different driver, which is more work for Sofirn, and would likely mean 14500 batteries only - no AA support.

It would be a very interesting product, however.

I was going to get another, but the Jetbeam U is only $2 more… beautiful finish, anodizing, and I like the multi-mode. But I’m glad to have one C01.

Do you mean $2 more than the C01s?

I think the cheapest I’ve seen the Jet-u for is $14.

Love my c01 lights, though I wish the beam was a bit narrower. Super excited about the c01s. Have one so far but holding out on more until if/when they release a L-H mode order.

I bought one for $9, and a 2nd one for $10. Usually there’s a coupon floating around. For one I used a $4 off AliExpress coupon. The other was on sale.
