After some long time, I finally got my Sofirn C01s last week (considering I believe I was one of the first to order from Sofirn AliExpress and reported here that they are already posted for sale in Ali… in this post [Available again! - BLF special edition light] new Sofirn AAA twisty high CRI 5mm LED - #1442 by d_t_a).
Anyway, my 2 orders actually arrived at the same time (the 1st order was the black C01 initially available, when I ordered them last 11/11/18), then I did another order of the blues and reds.
The C01 blues and reds work properly. They came with stiff pocket clips (OK).
But its the C01 blacks that I at first had trouble with, mainly: the heads are stiff to screw and unscrew… and one of the black C01 I got refused to work (no light) at first.
(side note: the black C01 also came with stiff pocket clip)
I tried finding out what’s the problem wth the black C01 (1st order): sticky white goo keeps on oozing out from the head, and in the case of the 1 sample that refused to work, I cleaned the goo from the head, and also from the body tube (it had flowed to the body tube), and after doing that, it finally worked!
However, my problem is:
those white goo keep on coming out, I have already cleaned 5-10 times (all the black C01s I got — I ordered a few pieces), and when they are clean and leave it for several hours, more goo seeps out from the head. They are sticky (and will also flow to the batteries when I test them)
when I took these pictures, I think it was already my 5th or 6th time wiping off the white goo from the black C01s…
they just keep on coming out — what do I need to do to “fix” them?
They are sticky and flow to the battery tube and the battery (making the battery sticky too)… And after wiping more than the 7th or 8th time, they still keep flowing out.
