[Available again! - BLF special edition light] new Sofirn AAA twisty high CRI 5mm LED

My stash of C01 just came in.

Uh-ooh, what is that white stuff?!

Well, some will like this a lot but not me who wants a host for other leds.

(To be viewed in 3D when crossing your eyes)
Hard solid potting! Great tough lights but not for modding. I guess I have a lot of lights to give away now :neutral_face:

Btw, I measured 7 lumen output, the beam is rather nice (not perfect but the Yuji version was not perfect either) and the tint is lovely (3300K, right on the BBL, 98CRI, R9=89)

I guess I will be begging for a host version after all, but I’m afraid all 5000 are done already :frowning:

Oh, sound wonderful for those searching for a LED cockroach :-D. And 7lm in 3400K is better than the Yuji with 6lm in 3200K I guess.

Since those are said to be not potted this is a bit strange but nice, so a real cockroach :-).

Crap.

Is it signed BLF C01?

Arrived yesterday - as you can see, no potting - bad luck djozz

Wow, Sofirn made it a lottery! :open_mouth:
I have a couple of orange ones too, will check.

The o-ring situation…
Hammering out de potting with a bolt on top of the led required a lot of force, but it worked. And the o-ring is a confirmative.

But also no o-ring! Well, glad I haven’t ordered them yet (10 were planned).

yes potted, yes O ring:
(I added the arrow and text)

Not Potted:

Does it have an O ring?

Additional info.

*All lights are labeled Sofirn C01
*I ordered 10x black, 8x green, 8x orange.
*All black and all green have potting.
*All orange have no potting (jay)
*I checked a potted black one and a non-potted orange one, both have o-rings in place around the led.

Edit: looks like your post was edited before I clicked quote lol.
I think he is referring to this image, which I am also not really able to definitively see an o ring in

I received my 3 C01 Red lights yesterday, all were potted. Beam is not super great, but I’m a big 5mm fan and I like the single mode. Will likely try sanding the emitter on one at some point and get comparison shots if no one has yet. My regular C01 lights should arrive today (1 of each color), I will report back about potting when they’re in.

(I added bolding about O rings)
thanks for the great info!

anyone have desert tan and blue 2020 C01? do they look potted or not?

same questions for the C01S and C01R… potted or not?

My C01R looks like it is Not Potted:

I really like the green ano, a nice deep olive. Here illuminated with 4500K 9080 219b :

Sorry, had to take my glasses off to see clearly - what I received as follows :

2 - orange - no potting does have o ring

1 - green - potted

1 - brown - no potting does have o ring

1 - blue - no potting does have o ring

1 red 670nm RED - potted

Is it just a simple 5mm inner diameter o-ring that would be needed after removing the potting material?

EDIT: Nevermind… I think they all have o-rings… brain is just a little foggy at the moment.

shirnask, thanks for the potting and O ring info, very helpful
Im satisfied that it appears All C01 have O rings around the 5mm LED

Oh, weird that they potted some of them but not the others!
Wonder if the factory didn’t get the memo when they manufactured certain colours.

maybe

or, I speculate

factory staff says: Boss, were running out of potting compound.

Boss says: those guys on BLF are really cheap… Im not buying another barrel of potting compound, too expensive, and too much labor. Finish the rest without potting…

factory staff says: Yes Boss :slight_smile:

and
factory staff says: Boss, the red 5mm LED has beam artifacts

Boss says: those guys on BLF are really cheap… Im not buying another bag of LEDs, too expensive, too much labor. Finish the rest with the LEDs you have.

factory staff says: Yes Boss!

One more here to confirm the above list, my colors are potted the same

Already did a first mod, one I was having in mind since the desire for a host version. Simplest travel nightlight ever for my son, for which application 7 lumen is too bright.

I used a 2300K 95 CRI led from rngwn (I cherrypicked one that was duv –0.0017) , which is shorter than the stock led so probably a littlebit light is lost in the head (looks like not much). And I changed the 220 (22 Ohm) resistor for a 221 (220 Ohm) resistor. The battery current went down from 70mA to 10mA (good for runtime) and the light went down from 7 lumen to 0.7 lumen (some of that reduction is caused by going from a 3400K led to a 2300K led). At 10mA, a AAA alkaline has about 2700mAh so that should be about 270 hours runtime (as opposed to about 40 hours for the stock light).

Scotchbrite vs stock

C01 670nm

Genius move by Sofirn in my opinion to pot some of the lights - what a fun surprise. I had ordered one potted color and one not-potted color already (plus two C01S).

Just ordered two more not-potted and planning to adjust output like djozz. What size resistor is used?
