Thanks for the link, Pete!

Interesting that he says 550-600 foot candles, so really bright. RCA literature for color studio design suggested 400 ft-c or so for TK-41s IIRC, but obviously that could increase if you set the key light for 400 and then added fill.

This leads me a little off-topic:
In our little table-top HD studio at Zenith in the early 90s, we used HID lamps and 400 foot-candles for the early Saticon HD cameras to get the minimum noise and lag, running the camera at minimum gain setting. It was a tightrope walk between low noise and the possibility of comet-tailing on shiny objects as the tiny cathodes on the HD Saticons were pushed to the limit during highlights to try to eliminate comet tails.

And a little further off-topic: one of the most fun parts of my job was visiting toy/souvenir shops in airports while on business travel to buy mechanical toys to put moving things in front of our camera. We had a small LGB train set, an even smaller Disney carnival set with characters on battery powered carnival rides, and a toy with little penquins that were carried to the top of a slide and then slid down to the base again; plus some small flags that could be made to wave with an out-of-scene fan, and a fancy-dressed collectible doll that provided some skin tones. All of the toys eventually failed except the LGB train, which was sold to an employee as lab surplus.
