I have one and it is not the total answer or a 100% certainty that its
readings will always under all situations be 100% spot on; or that even if
it does give you the correct filtration, that you will be able to find
combinations of filters that give that exact reading or do not have other
side effects in terms of the required f-stops that need to be added to
account for lost light or increases in the length of exposure.  It is only a
useful or helpful tool and not an answer. <<


I used one several times a week for about 5 years, mostly in industrial
locations with mixed lighting. I got to know it well and found it to be
accurate and consistent.

The use of a colour meter is certainly more accurate and faster than mixing
and matching flourescent bulbs, not to mention that you could almost buy one
for the cost of 40 rolls of film and processing. If you filter the light
source then exposure considerations aren't an issue. And the high CRI
fluorescent tubes are easy to fine tune with the colour meter.

Even though it may not be 100% spot on, it'll get your quite close with a
minimum of time, hassle, and expense, and that's the reason I suggested it.
