The electrician should advise on the load limits of both the track and the fuse or breaker to which the track will be connected, but depending on what else is connected to the same load limiter you may have substantial leeway.
Benny,
I have the Solux 4 head 'Color Proofing Light Kit.' (
http://www.solux.net/cgi-bin/tlistore/colorproofkit.html )
The instructions stated that for 8' ceilings the fixture should be 24" out from the wall. For your ceiling height you should be able to "do the math" to get it right for the height of your desired "viewing area."
I had my electrician put the track on its own breaker in the panel, just to be safe. I also installed a remote operated light switch from Lutron so that I can turn the lights on and off while sitting right at the computer. I, too, have magnetic panels on the wall to the left of my workstation, and use magnetic "tacks" to hold the print to be evaluated in its correct position. The panel came from Diamond Life:

Addenda: Be aware that when you first fire them up (the kit cited above) that they stink to high heaven as the paint on the fixtures "heat cures" (or whatever it is doing!). My poor electrician thought he was lighting my house on fire for all the "burnt smell" that occurred! Never saw anyone go up the scuttle hole ladder that fast to check out the wiring above! The smell went away after about half an hour.
If you'd like a photo of the setup, shoot me a PM.
