This was a gamble: but it turns out great! I wanted fundamental color LEDs, not the blue ones with a phosphor color layer. The images on the advertisement looked ok, but the working voltage of 3.0-3.3V hinted at blue LEDs. But no, these are fundamental 560nm LEDs and the working voltage is 2.2-2.6V as expected for this color. Recommended!
