Suggestions on your favorite 5mm LED diodes, preferably with a Vf of ~3V? I’ve been on the hunt for some high CRI diodes for projects, and wanted to pick up some Yujis, only to discover they are completely out of stock and do not plan on making any more going forward.
Generally THT components are outdated and no longer actively developed, hence why all the new high CRI LEDs are surface mount. It might be cheaper to buy an adapter PCB to run a modern high CRI power LED or even a Sunlike (violet pumped) at the same currents your THT LEDs would’ve run at

Are we talking “5mm” as in T-1¾ bipin LEDs, or as in 5050 chip LEDs?
Old skool plastic diodes. Those Yuji were “The Thing” back around the time of the Sofirn C01 lights, a couple of people were modding the Fenix E10(?) AAA lights that had cold white 5mm LED.
I’ve found it almost impossible to get high CRI 5mm LEDs for reasonable prices the last few times I’ve looked. I have a few crappy multi 5mm emitter lights hanging around that would be fun (but pretty pointless) to upgrade.

Pointless, but surprisingly fun. It’s nice to just pop replacements in, and usually doesn’t even require soldering. I just like the idea of a low lumen light, and plan on upgrading a bunch of fauxtons and giving them away.

Yup this was my original plan, along with one of those “72 LED work lamp” plastic brick shaped things which takes 4AAs, the LEDs are just soldered on a simple PCB so fairly easy to change. Alas, it appears the best LEDs are even less available.
You could make a small PCB that adapts a Nichia E17 to a THT footprint.

You could go look on ebay or craigslist etc. for older cheap photography lights, they often had 5mm LEDs inside before they went to SMD.

You’d be surprised to learn how many Photon Freedoms I modded with both the 3200k and 5600k Yujis.

That’s the plan. I just wanna get a bunch of fauxtons fixed up with better LEDs and fresh batteries and hand them out like candy. Teachers or parents of kids around the school without a light? Here you go. Homeless person around town? Fresh socks, nonperishable food, and a light. Neighbors that can’t seem to see the lock of their front door and are bringing out their phones for illumination? Have a light. They’re cheap enough that I don’t feel bad giving them away, and small enough that most people won’t have any qualms about carrying them.
