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

:smiley: So…. What happened?

Nhami nhami, seems like a decapitated Yuji panna cotta :smiley:

Why you slice it, djozz?

Gave mine a shower last night, passed the waterproof in flying color.

This evening my son (10) gave me this C01 "diffuser cap" as a present.

Happy dad with a great bed side light now.

^ Welterusten! :slight_smile:

Excellent work! I especially love the smiling moon!

Is that his artwork in your new avatar as well?

Stupid question, but it just occurred to me. Do these “strawhat” LEDs work similarly to the Cree/Nichia/etc. with a blue LED covered in phosphor? Or are they something different?

Just received my 5600K version. I also was curious about these Yuji High CRI LED’s. dijozz’s post just about sums it up for me. :wink:

It’s a very nice light for $7.00, (what I paid), though. Kind of reminds me of my ARC AAA I had years ago except the ARC had a bit better build but was expensive for it’s day and of course the Yuji is a much better 5mm LED then ARC could source back in the day.

The tint on my 5600K is very nice. My example also twists on and off very smoothly. All in all, it’s a very nice $7.00 light.

By the way, I plan on installing the 5X3mm magnet and trit in the tail. I just use Duco cement to install the trits. I’ve installed a few trits with it and it works great. It dries crystal clear, is cheap and really holds. I prep the slot with 90% rubbing alcohol, lay the trit in and cover with the Duco.

What I tried was this, I sacrified a second C01 for it:

I wanted a mule with evenly tinted light in all directions for checking an integrating sphere, and indeed up to the very edge of the beam I measure the same spectrum with my spectrometer.

I thought throw increases after dedoming :open_mouth:

what machine you used to do that djozz?

To my eyes those look like sanding marks.

A small band saw, then a disc sander, then sand paper.

After this run of C01’s sell out, Sofirn should make the second version with two modes. (5 lumens / 180 lumens) Is the Yugi LED capable of 100+ lumens?

I think not even 18.

that would be a different light :slight_smile:
available from Olight

Haha! I wondered from the first picture if djozz might have been “de-doming” a 5mm emitter for some reason.

Sorry to hear the first one didn’t survive. Looks like you got more than just the bond wires.

Yes, they work basically the same. However, Yuji specializes entirely in high CRI phosphors.

They also use violet LED’s in some of their products (VTC series), which extends improvements in color rendering to the deep blues and purple range, but reduces efficiency and results in a higher forward voltage. Extension into the violet range is less critical than extension into the red range for viewing skin tones and wood, but can still be important for viewing artwork, for example.

By the way, I’ve generally understood “straw hat” to refer specifically to LED’s with an inverted or dimpled dome, like some straw hats have (example), which provides a very wide beam.

Ya I have the i3t but something like that with high CRI and nice warm tint 3200/4000 would even if the high was around 50-100 lumens. I guess the one thing like that is the reylight, but I’m waiting to see if a new version of the pineapple gets made. I really like lights that can clip to hats. I do have a couple C01’s because they seem cool, especially the warm one, but it’d be nice if they were brighter or two modes.

Thanks for the explanation!

And, of course, you are correct. I had heard that, and somewhere seen “strawhat” applied to the Yujis, so I assumed it applied to all the old-school non-SMT LED packaging, but it doesn’t.

Again, thanks.
