It’s basically a new version of the Q8WP which koef3 tested here: LED test / review – Osram OSTAR Projection Compact LE UW Q8WP – Black Flat's big brother, very high luminance at higher flux!
CSLPM1.TG is to the Q8WP what the CSLNM1.TG (white flat) is to the black flat.
The boost HX is the CULPM1.TG, they are not two different LEDs, it has a rectangular die just like the CSLPM1.TG and Q8WP.
Just google “KW CULPM1.TG” and it’s one of the first few results, a pdf.
