I have four Solux 4700 K 36deg floods that are about 1-2 years old
with 100-300 hours (or so) on them. The only variation can be hours
of use. I will be ordering a new batch quite soon. If you are still
interested get back to me in 7-10 days and I'll report the newest
findings.
# 1 = 4363 K
# 2 = 4550 K
# 3 = 4307 K
# 4 = 4456 K
They were measured with an i1 Rev D (UV incl) in Emissive-Light mode,
using Robin Myers SpectraShop.
As Robin said earlier, I have never found a bulb to be the actual
stated CCT. All except one.
I just rebuilt my light bleaching set-up and purchased a $120, 250 W,
Metal Halide "Hostile - Blue" lamp (Eye Lighting, Japan) that outputs
6530 K +/- 35, with 16500 Lux, about 20" from the bulbs; less than 1
hour old. As one would expect, it is a bit spiky, but not as bad as
normal Metal Halide lamps. They label it 6500K in the PDF;
