    Seeing them like that, that Sophia LED really makes for a nice light!

    Why no red body C01 colors in aliexpress? The red body is available only in CO1R & CO1S

    True, there is no Red Body C01 w High CRI Sophia 3400k LED

    The Red Body C01 is only available with red LED



    the listing on sofirnlight makes it more clear that the Red Body is only available w 670nm red LED:

    Just ordered a couple more of the Sophia lights and one of the 670`s (mainly out of curiosity how it compares to the CO1R).
    I have some AAA batts to get rid off and though they`re unlikely to leak, I`d hate to have it happen to my only one!

    yes, and it is just as durable as this one, kid tested in 2018, that is not potted:

    Jon, I ordered a few more, color black & green, potted C01's
    Thanks for the info..

    Btw, if you're not promoting for Barry, or Lan. You should be on their payroll

    enjoy your options

    Im not affiliated,

    I think of myself as a Johnny Appleseed of High CRI
    and AAA is a favorite size

    The C01 is part of my masterplan for High CRI Domination of the world. lol

    what is the diffrence between CO1R XPE2 660nm deep red

    vs

    670 nm red led?

    any side by side photos?

    Default Re: Sofirn C01 for 2020

    the two models use different LED technology


    the C01R is more powerful, has more modes, and a cleaner beam
    it uses this sort of LED, and the head of the light has a lens over it:


    the C01 5mm 670nm LED is a simpler technology, only one mode, and there is no additional lens on the front of the head:




    ===



    imo the C01R, on the left, is very nice,
    the three lumen levels from my meter, are in the photo above...

    I do not recommend the C01 670nm, on the right, because it only has one very low level, and the beam has rings and artifacts

    why is the 670nm price above the CO1R?

    I think this C01R has taken a dump, and only after two nights of use lol

    If you look across the contact plate, it appears sunken lower than threads on right side making proper electrical contact impossible.. Twisting mode change can only be achieved now by cranking down hard


    Nice emitter tho, too bad rest of this light is mfgr'd without proper quality control

    prices are different on Ali than on the sofirn site, there is also a difference in shipping cost
    I cant tell you "why", it is simply true as you observed.

    knucklegary, thanks for encouraging my contributions, much appreciated

    I dont see anything obviously wrong with your C01R.. I hope you manage to solve any issue..

    fwiw, the red arrow points to a NON contact point. The light is activated by the paddle, green arrow, contacting a silver ring, shelf, in the body.





    Yours is the second report of needing to twist hard to make contact. I dont know why..


    my guesses are
    1. dielectric grease on the silver ring could interfere with electrical contact. solution, clean with alcohol...

    2. the head is not going deep enough into the body to make contact. possible solutions would be to find ways to increase the reach of the contact paddle, such as a solder blob on the contact paddle, or sanding down the end of the body tube so it does not hit the head before the contact paddle hits the contact ring in the body. Or lifting the driver, with a shim under the part the green arrow points to, so it sits a bit more proud of the head.

    of course those would be fixes you should not have to do

    I encourage you to contact sofirnlight.com, maybe they will send you a replacement.. however, if the issue is a manufacturing error, in cutting the shelf in the body too deep, then the issue will still be there on the replacement.

    I have not received an SST-20 660nm.. mine is XP-E2 660nm.

    fwiw, my driver also sits with one side low, like yours, I dont think that is the issue.. my focus is on the paddle making contact with the ring in the body..

    jon,

    thanks for informing about sofirn website. Its cheaper the C01 sophia & 670nm there than in my country. Price here in philippine peso 359 to 379. In sofirn website its 200pesos to 220pesos

    the C01R price in my country 359pesos its xpe2 660nm. On the sofirn website sst20-dr its 500pesos. But cannot compare different cree.

    Jon, you are correct about the shoulder (shelf) inside body not making proper contact with driver paddles

    I applied machinist Dykem Blue used for high spot indicator when mating metal surfaces.. There is Not enough contact on body shelf. You are correct it is cut too low on my sample C01R.. and probably more made this way came off the machine

    Contacted Sofirn and should get a reply later today

    The real bummer is I ordered another C01R just the other day.. Looks like I got my work cut out for me..

    Btw, the body threads can only be shortened very little before creates other fitment issues

    If the Malkoff posse are taking notes, I'm still in for a drop-in with SST-20 DR 660nm

    Edit: switched DR head to C01S body and problem is eliminated. Obviously a tooling set-up issue after taking a magnifying view of the shelf

    I disagree with my younget self's suggestion to shorten the body
    the older and wiser me says, the lack of potting has allowed the pill to sink into the head too far, as you noted from the tilt

    so, my fix would be to stuff a little .1mm thick shim, I happen to have thermal tape, under the ears, with the goal of lifting the contact point..



    disclaimer, I have not, yet, had reason to take a C01 head apart myself, but I think that contact pad is just press fit in place, shimming it up slightly should not require any unsoldering afaik..

    in my case, the red C01R you see in the photo with the tilted contact pad, still works. I dont have to twist hard.

    I hope you get yours working easily.

    Jon, I thought the same at first, although I took C01R head screwed onto a C01S body, and works okay..

    Well, at least for the time being it works. It could be the head driver "notch" cutting into the shelf where the driver sits low. After a few twists the C01S body might be screwed as well, excuse the pun (:

    Edit: Hope a Sofirn rep Lan is also taking notes for their Engineering Dept..

    agree
    if the notch in the head reaches the shelf before the contact pad on the pill.. no continuity

    the fix will still be to lift the pcb so it sits higher than the notch

    I think this is an unanticipated consequence, from converting to a different driver, which happens to lack the potting hole. So the contact points sit lower than in the potted version.

    Well, it’s a totally different style of light but check out the AA stainless steel from fireflies. Just received one yesterday and it’s definitely built like a take. From the lens to the body to the switch this thing feels like it could take quite a beating.

    I've had a light or two of that style not fire. More times than not the pill was screwed in too far. Backing it out a 1/4 to 1/2 turn. I would unscrew the pill (after getting the glue soft) place a small sliver of gap filler like foil on one side and using E3000 epoxy and reassemble not twisting it back in as far. Let cure overnight.

    If the driver is sitting too low, why don't you remove it and sand the "wings" to make the notch shallower?

    Just google “1.5x6 mm tritium” and you will find several suppliers of the tritium tubes.

    Dang, the tubes cost more than the light did.
