I apologize for going off topic but,
Could someone please enlighten me what is a WJ/3A tint? Or some other neutral/warm white tints? The only neutral white I have is a Quark with XP-E Q3-5A. Maybe if someone could use the XP-E Q3-5A as a benchmark and explain to me where those other tints fall in terms of warmness I would appreciate very much. What are the difference also between the Q3-5A and Q3-5B? And Q3 versus Q4? I am going nuts trying to understand.
I hope this will help, I started a thread because I was confused by the Cree model numbers. there is some great info in there, hope it helps.

I will give your question a shot, but I am very new to flashlights. The Q3, Q4, R2, R5 etc refers to the flux bin (efficiency of the LED, how much light is emitted at a certain power) see this chart

the second part WC, WD, WH or 3A, 5A, 5B refers to the color that is emitted. Anything that starts with a letter is on the cool side, anything that start with a number is on the neutral to warm side.
link to the warm color chart the Cree cool white chart was not in this thread but take a look at it for color charts for other manufactures
link. The cool white chart for Cree is in the PDF that Uplight linked to above.
