I already bought two of them to try out, though those results have me thinking of increasing the order immediately.

I’m going to put one in the Olight WM2 I reviewed a while back and then sell it for more than I could ask for a stock one. I can think of several other 3V lights where a 519A might be overdriven where this is very appropriate.

High CRI, warm white thrower LED. I can’t think of any good thrower LEDs like this, they were all CRI 70 at best and 6500k (old SFT-40, W1, W2).

The Nichia 519A and 719A are high CRI, but they can’t be driven as hard as the SFT-40.
