I would hazard a guess at 219c. Cleverly they just put 219 on the case! Last couple I had from Flashaholics are 219c. Sure they have confirmed it as well. Sportac did not inform them afaik either. They are nice P, just not the rosy we get from the 219b. More toward yellow side to my eyes, nothing like the xpl2 yellow though.
Although not nichia, the neutral xhp35 HI is nice, slight golden to the "tint". In ways it's like an m61 on steroids, around 4000k.
Could ask flashalolics if they can see for any old stock, also worth dropping illumination gear a message to see if they can get their hands on 219b. Never know! Shipping is fast and a reasonable $15. I bet their xpg2 4000k sportac is a winner. I have the EDC+ with the said, it's very easy/nice on the eye(think Malkoff neutral 4k in a triple).
