Red LED's are Orange !!

Fact is that the ZebraLight H502pr is NOT "deep red"; in fact it is even less "red" than the other red LEDs. The grating setup gives a heavy indication that my eyes are right.

Communicating with ZL seems to indicate that ZL will not confirm my suspicion, and seems to blame the driver.

Mine looks deep red , it makes my other red Astro lights look orange.

Little point posting pictures of deep-red LEDs. The longest wavelength your monitor can produce is approximately 610nm, which is the red primary pixel colour. See this diagram — the "sail shape" is what the eye can perceive, and the white triangle is the sRGB standard to which most camera outputs and monitors are calibrated, colours that can be made by mixing different amounts of the red, green and blue primaries. The red primary is the right-hand vertex of the white triangle. Obviously, the colours in the diagram are only indications, as your monitor cannot display anything outside the white triangle.
