Its a tough one to call, for me anyway. I would put it around 5000-5200k , but again its tough! Against white walls(not recommended as serves no purpose other than to find blemishes that are lost outdoors). Outside, greens etc, be it wooded areas or garden, the PDT really does shine imo..............colours look good. Used in artificial cool light, the tint can look a little green(common by product of de-dome xp-g2), so for outdoor use , its at its best. The beam is quite a bit tighter, the broad flood is compacted into a tighter beam compared to the standard D4 pattern. Its still a usable beam close up though..........
Hard to say if you would be happy, i am not a total tint snob but do appreciate a nice "tint". So a fan here of 219b and 219c, like a little rosy or warm, also like a pure white(or clean white) of the 219c 5000k. Nichia 219c 5000k is hard to beat, if you want a little warmth the xpl HI 4000k is fantastic. Just adds that little bit of warmth to pump up colours slightly without looking too artificial. The xp-g2 4000k is also nice!
Maybe your closest is the xpl HI 4k, other side would be the xpl HI 5000k..............The 219c 5000k has the highest CRI if that is an important factor. Trouble is they are all good/nice in their own way, thats why people tend to get more than one. For me, cool 5000k in day(work), 4k in the evening. I can use either way round, 4k all day and night, 5k all day and night. Just my preferences are 5k day, 4k night.
Really subjective...........
