Most likely not a blue emitting LED but rather a white light LED with a blue cover....not even close to the same thing

White LEDs are usually blue LEDs with a broad spectrum phosphor, although some are red, green and blue LEDs in the same package.

Yep.. That's what I was going to say.

Oh that White LEDs (Phosphor coated Blue LEDS) and Lithium batteries had been around in my mine and cave exploration days.

Sometimes we would stay underground for a week or more, and the logistics of having light would have been so much easier.
