Seems odd that anyone would critique prints with an incandescent light source.
The design seems OK but I would suggest using Solux lights.
Given the age of these designs, I doubt that Solux lights were widely used, if even available. If you look carefully, you'll see that they used a mix of fluorescent and tungsten light.
Solux bulbs may work fine, but you should also take into account the amount of heat they generate. Black-backed Solux bulbs might help reduce the heat from the rear of the bulbs.
