Curiously, the clock was put in as a light_source color when I tried this.
Thought maybe it went to -1 and luckily I used a simple candle scene, lit
externally by that other light, so the flame light should have still been there.

Tried -1 instead of clock and the flame light was still there, just not the same
as with the NaN clock! Found it takes more like -100 to get the equivalent
appearance, extinguishing the flame entirely. Difficult to know exactly but -50
was ever so slightly different on the wick and melted wax edges.

Try and explain that. Why would it equate to approximately -100 for a
light_source? Anyway... going astray I fear.  ;)
