Howdy Sealhead,
My Farthing's worth on'Lighting'.
I have multiple light sources at my modeling desk. Six (6) different ones to be exact. But they essentially break down into three (3) categories. Main, Spot, and True.
Your Main light source can be flourescent, halogen, or incandescent. Flourescent provides light with a 'bluish' tone and very little heat, halogen more to the 'whiter' side of the scale with much more heat, and incandescent producing a light on the 'reddish' side of the colour spectrum and about the same amount of heat as the halogen.
When I am cleaning parts I just cut off the sprue I do the majority of my clean-up under the lighted magnifier with a circular flouresecent bulb, thereby avoiding the prolonged heat of the incandescent, then I switch to the incandescent powered magnifier to really see deep within those moulded details and do the finish clean-up.
The only word I will share with you in regards to the Ott-Lite type of lighting is 'Natural'. All the Ott-Lite is doing is producing Sunlight! That is the only 'true' full spectrum light (why I love to model out on the deck during the Spring and Summer. :-)
If your modeling military AFV's, 'true' spectrum lighting is not essential, desired, but not essential. Where it really comes into play is when doing figures, and such. Where a more 'discerning' colour rendition is important.
HTH.
