Interesting. I wonder what bin my ROT66 has, because whatever it has it is cooler and less green than the SST20s in my Copper E07.

Maybe my ROT66 has the FB4 and E07 has FC4, and the cooler CCT just looks rosier naturally.

Original ROT66 was 20 or 25 degree optics right? These new otpics don’t look that much larger than the original ROT66, will be interesting to compare beams. They definitely fill up the head much more efficiently than the 9 of the original.
