Following up on u/kotarak's excellent work, I thought I'd put my new ColorMunki to work measuring the various configurations of X1S + FFL707MD 4200K with regards to lenses, TIRs, and reflectors. The specific optics make a big difference in the dUV and CCT of the resulting beam! For bare emitter measurements, I put in a slip of white paper to try and minimize the effect of the anodizing on the light. I'm reading the hotspot for all measurements.

Here's the summary of the data:

Optics w/ Lens w/o Lens
Bare 4634K -0.0045 dUV 4652K -0.0045 dUV
Reflector (OP) 4062K -0.0011 dUV 4111K +0.0001 dUV
TIR (pebbled) 4053K -0.0029 dUV 4103K -0.0025 dUV

It seems like the lens makes a much bigger difference when combined with a reflector than with other types of optics. Hopefully you all find this data useful!
