[argyllcms] OT: Viewing light?

So, I might wind up with more art reproduction work. Still family and friends to start, but a job worth doing....
I'd like to have a good reference light source to match what I see on the display to the original.
There doesn't seem to be any consensus on the 'Net. SoLux gets rave reviews, but they're a very low color temperature and a very high operating temperature...and I'm in the middle of the Arizona desert. All the multi-thousand dollar light booths use fluorescent D50 and D65 sources, but they're spiky -- and $$$$!
I've been taking prints to the window or outside to make sure they're okay, and that works great...but it won't work for side-by-side tweaking. 

Any suggestions?
I've half a mind to buy just the replacement bulb for one of the $$$$ booths, a generic dimmable fixture, some cheap plywood, and a can of neutral gray paint. Surely there can't be that much more to it than that, can there?
And, once I get a solution, whatever it is, can I calibrate and profile the display to match the light source? (I've got an i1 Pro.) 

Cheers,

b&
