Observing various HPS installations, I've noticed that some lamps turn
their yellow-orange sodium color very early in warmup, whereas other
lamps initially look white like a phosphored mercury or a metal halide
lamp and don't reach their final color until much later in warmup.
I'm just curious what accounts for the difference in behavior. Is it
primarily just dependent on the lamp brand or type, or is it age-related?
