If you don’t mind LEDs already installed in quad TIR host, AFAIK both of Convoy’s S21D and M21H have 219b sw45k. The ones in his S21D have Duv around -0.0090 to -0.0100.
S21D runs very hot on Turbo (ok other mode, read caution here), but M21H is ok heat wise. Knowing this wonderful sw45k LED is extinct, I’ve bought 2 of each host, all fantastic.
