I have a Midland ER210 emergency radio flashlight combo that has this pictured LED in it. Interestingly it is dual color red/white (discovered by accident when I reversed polarity to it) the red portion is not used in the radio at all. no combination of button presses or holding turns it on. as interesting as this LED is. I would like to replace it with a warm white LED. the LED seems to have pads protruding out of the sides. it is seeming to be around 3mm maybe 3 and a half. if the replacement LED could have decent CRI and decent brightness that would be preferable.
it will not let me embed more than one picture in a single post so now I have to create multiple posts in order to share all the images. I am not doing a collage right now.
Here is the last image with the red LEDs operating. there seems to be two separate red LEDs. If anyone could identify this chip, i would like to obtain more of them.
The typical LED would be the Nichia 519a: 519A LED , high CRI R9080 - Convoy flashlight
Reflowing isn’t that hard if you haven’t done it yet.
It is easier when you buy the led on a PCB because then it already has some solder on the contacts.

Awesome. they are rather cheap as well. I ordered 1800k, 2500k, 3000k and a 5700k to play with. I ordered the 5700k just for giggles. I will likely use it somewhere. I wish to see what it looks like.

The only Led im aware that has this aberration is XPG3

True.

UPDATE!:
I have finally recieved the LEDs after many days of wait. Here is the results:
I went with the 2500K lamp. 1800K was really orangish. And 3000k was okay but i wanted warmer. Light quality is excellent. Obviously rhis flash light does not drive the diode to full potential but I dont want max brightness out of it. I want decent color and long living battery. It lasts a really long time. and pushes something like 200-300 lumens.
