Lately I’ve used my first 100 of these hi CRI 5mm 3400K LED’s from rngwn:
2300k/3400k/5000k/5800k 5mm LED 95+ CRI
Already started on the second 100 pack, I have more on the way and also some of the 2300K to try.
They come out to about 16 cents a piece delivered at quantity 100 and I have found all kinds of use to turn craptastic 5mm LED lights wonderful. It doesn’t cost much to spread a little hi CRI goodness 10 lumens at a time. A 60 degree floody beam, warm white, tolerant being over driven. Most recent was some old useless solar path lights I found in the garage.
