This morning, I made a series of color measurements on Solux
50W/35degrees/4700K bulbs using a variable AC and DC voltage generator. The
results are as follows (chromaticity measured with a Minolta ChromaMeter I):
AC
------------------------
V x y CCT
--- ---- ---- ------
12 .363 .372 4478
12.5 .359 .369 4597
13 .356 .367 4675
14 .348 .362 4929
DC
------------------------
V x y CCT
--- ---- ---- ------
12 .349 .365 4905
14 .335 .353 5399
I was trying to test the manufacturer's claim of 4700 K.
Is anyone using these bulbs for museums or art gallery? And what kind of
special power supply do you have to use to drive these bulbs?
I am interested in putting together an affordable viewing environment for my
graphic design students who need to prepare artwork for printing on offset
presses.
