Although time doesn't let me read all the info on your link, from a photographer's point of view much of what was said was correct, but some wasn't. The talk about 5000k being ideal for photography is only that because sunlight is generally just a bit cooler at 5500K--not much of a difference. There is also mention of 3000K being used for what is commonly known as photofloods. The lights that he might be referring to were actually 3400K with Kodak's Kodachrome Type A being the only film made in recent history--now obsolete. Typical photography 'hot' lights were in the 3200K range in either a tungsten or quartz varieties. They are still in common use, fairly cheap and durable. When it comes to a Kelvin rating on fluorescent tubes--technically there isn't a rating but there are great differences in the color rendering. The newer compact bulbs are generally better for viewing and photography purposes.
Again from a photographer's standpoint the typical overhead valance is a real 'bugger' to deal with. Let me explain, it's typical to have the valance drop down at the edge of the layout. This causes the front elements in the layout to often be in shadow as the lighting is coming down in a 12 o'clock noon pattern--typically the worst time in the day for lighting. So when guys like us come in we see all these dark shadows up front; we try and light the area, but the valence is now in the way. This is compounded if the layout is double decked. I recently worked on such a layout where the trees and buildings were only a couple of inches from the fluorescent tubes. If you us the laws of physics, you will figure out that the lighting on the top of a building might be 10x what the lighting might be on the 'ground' thus making the layout very uneven. General rule thumb, if your going to do a valance, put it out front by a foot or two--probably just about above the typical viewer. It's generally okay to have lights in the back of the layout also, but keep some up front. My layout is lit by fluorescent tubes most of the time, but I do have track lighting with floods and spots that I use to put emphasis in key areas. I hope they make replacement LED's that are inexpensive (I view the CFL's as a temporary solution), because the heat is certainly a factor.
