[1900k edition is in!] WTS: 1900k-5800k 5mm LED 95+ CRI

[SKV89]

I would love to participate but don’t know how to use these emitters. Do they require soldering? Also which flashlight host can these go into?

[rngwn]

^soldering is required. You will find LED similar to these on keychain lights, or some other flashlights discussed earlier in this thread.

There is also an interest list by Djozz for C01 host, but I’m not sure if its ever going to happen.

… these emitters. Do they require soldering? Also which flashlight host can these go into?

Which not?

There have been some mentions here:

• “Power Beam” bike light reviewed by me @ FastTech.
• Fenix E01 (Dsoto 87 review).
• Sofirn C01.
• Mateminco BL-01 (cheap LR41 sources here).
• FastTech Mini LED flashlight.
• Hand crank dynamo flashlight (alternative source).
• “Red Cross” Blackout Buddy and Clipray plus Coghlans dynamo.

I pulled 3 random LEDs from the 2nd batch for spot-check.

Here’s the light (appearance) test on 5500k WB and 2800k WB

Received the package of 100.
There will not be a proper review until next tuesday (I will have enough forum chat time but there will be no hands-on cave time possible).

Quick first impression of one random led from the package:
*plenty bright
*very pleasant tint to look at
*very smooth broad beam (60 degrees from specs seem correct)
*edge of the beam a bit warmer than the rest (found it not disturbing)
*at ~20mA, middle of hotspot: 3325K, duv –0.0039, CRI=97.4, R9=88.

Summary so far: great led

Wow! Sofirn should get some of these.

[Barkuti]

Many will be waiting for the review djozz. Thanks.

Any 7x emitter honeycomb arrangement host or flashlight out there for these? Hexagonal/honeycomb is the most dense arrangement, I wonder why it doesn't seems to be widely used.

[rngwn]

How about this as a host? It’s 0.5w though, so I don’t know if my LEDs would survive that.

GREAT! :+1:

I’m really looking forward to seeing the results of your testing.

Re-posting this old Yuji mod just for ideas:

My first LED swap which didn’t require solder. In fact I only used a screwdriver, wire cutters, and tweezers:

I recently ordered some batteries from Shockli’s aliexpress store and they threw in some freebies with my order. One was this cheapo keychain light. It has a 5mm straw hat LED that is press to activate and has a tiny switch to “lock” it on.

I bent and trimmed the legs of my Yuji 95 CRI 3200K LED

We have light!

I just now am realizing it had 2 stacked CR2016 batteries so I am probably giving this thing way too much voltage? Maybe a 2032 battery would have been more appropriate, who knows. I guess if it dies i’m out 55 cents…

If you still have stock I woukd be interested in 1 pack as well. See the PM.

The CR2016 cells are 1.5V nominal, so two of them would be 3V, which is fine for a white LED.
