Really would prefer something with a better color temperature, about 3500K that cuts through fog and has a decent CRI. I like useful tools, not so much about the show off toys.
It seems to me that the important "heart" of the module, the heatsinked phosphor blend, is hard to find.
However, high-CRI blends are common on LEDs we have today. We'd be limited to reflection-based LEP, but perhaps a DIY using an LED purely as a heatsinked target could be a possibility. However, just like within the LED, the overdriving of the phosphor could have unintended consequences even if it is adequately heatsinked.
The LED must be heatsinked while keeping electrically isolated from the heatsink. If used as an LEP target, no such need. Remember back in the day, when people were filing Cree XR bases super thin to minimize the ceramic in the thermal path?
All goes out the window if someone can find some premade sapphire windows with good high cri phosphor
