XP-L2 makes more lumens, but has terribly ugly tint unless it’s behind a pretty strong diffuser. So it works well in a light bulb, but not in a flashlight.
The XP-L2 5D4 from Simon, albeit behind a 45dg TIR, is very rosy and one of the prettiest emitters I’ve seen. It makes the FD2 SST-20 4000K 95CRI look like crap and even my rosy mixed 3500K E21A looks less good than the 5D4.
However Simon doesn’t want to buy a new 1000pcs batch because he believes long term storage causes leds to rust :person_facepalming:
Same story with SST-20. It emits most of its green spectrum to the side, so the forward-facing part of a mule looks really nice. The beam only looks bad when focused.
So I took the optics out of my 18-LED soda can lights and the result looks much nicer now. But the only time I need that type of beam is while shooting photos indoors at night. It’s great for getting a global illumination effect via ceiling bounce.
