BW02 is the designation for a Lux batwing emitter using the newer "EOS" phosphor application process. PWAJ is the binning: P=flux bin, WA= white tint bin, J=Vf bin. See AB21 for secret decoder ring.
Thanks Idle! hadn't seen that one. b2p, most of the modders are using Lambertian/high dome emitters, not batwings, with T (not P) flux, emitters and WO tint if we can get it. J ain't too bad for a Vf.
