Reliable ref. lighting is a wonderful thing to have and while it can
give you great results in comparing to display it may not be good for
real world conditions where vieing color and brightness are typ
different.  Being able to also view results in lower [different] K and
lux setting could be of benefit depending on the audience you print
for and materials used.

I calibrate my LCD monitor to a gamma 0f 2.2 and 5000K. 

For print viewing and evaluation I use a D50 standard light 
source: "...SoLux 4700K is the light that best simulates the D50 
standard..." This is a quote from the solix site. (what else would 
they say?)

I researched lighting extensively and arrived at this conclusion as 
the best compromise for me. My prints are usually viewed by tungsten 
or florescent light, and look good in daylight.

Take a look at the solux site: http://www.solux.net/cgi-
bin/tlistore/infopages/index.html.

I started using their bulbs almost two years ago and I am still using 
the original bulbs even though I bought spares.  Their light fixtures 
can be a bit pricy but they have a couple of inexpensive versions, 
one of which I use.

I also calibrate my printer with SpyderPrint3 which does a great job. 
i calibrate my monitor with an Eyeone2 and have an older Spyder2 for 
backup.

Good luck,

DavidL

Thanks for the Solux pointer. I'll give them a try.

It wasn't clear to me: do each of the fixtures have a transformer in 
them or is the track driven by 12v?

tnx

Each of the lamp fixtures have a transformer built-in that takes the 115/120
voltage down to 12V.  The fixtures I recommend are their standard utility
all black.  One is a desk type articulated model and the other is a clip on.
I Paid $100 for the desk type including the bulb.  Track lighting was
overkill for me.  I would consider track lighting for a gallery display
setting.

Our "proofing wall" will probably need to be about 2ft by 3ft to 
accomodate a couple of large prints at a time for comparison.

How large a print are you able to proof with your single 50w light?

tnx

I proof 13 X 19" prints (HP B9180 & 8750) and I have two lights, the other
one is a European design Solux that I use as a desk lamp as well.  If you
want to go wider then I would suggest that you build a track light array.  I
just looked at the Solux site and noted that they sell the components to
allow you to build a track system to your own spec.  If you have a very high
ceiling, you might want to take a look at their dual wall mount light setup.
I imagine you could have a series of wall mount lights.  You also might
consider which of the 4700K bulbs you want because they come in different
angles of coverage. My bulbs are 36deg. Since both my lamps are articulated
I can raise or lower to get the desired coverage. Their web page is
solux.net.
