Played with a triple XP-G3 I got from RobertB/CaptRon25 today with a couple of different optics. It was taken from a Wuben T046R with a claimed CRI of 90. Turned out it wasn’t high CRI, but the more interesting thing for me was the tint shift and beam as a triple.
Here’s the results using a heavily frosted Carclo triple optics with pretty much no visible hotspot and very low apparent output. The result is not bad at all.
Here it is with an almost clear, very slightly frosted with a much worse results. Even though the shift direction change near the hotspot is not as apparent, the overall tint is very unpleasant, cool and purple at 7000K and duv of –0.004. It is also very noticeably green towards the spill.
I still think the FW03 should be made with Nichias or at least the choice of optics and its setting must be very carefully optimized.
