1) Which light beam has the higher color temperature?
Lime Green - Lime green has a wavelength in angstrom units of approximately 5,000,000. Magenta would have a wavelength of about 7,000,000. This is a scale of one ten-millionth of a millimeter - in other words on the negative side of one. Lime green thus is -5,000,000mm and Magenta is -7,000,000mm. Lime green has the brighter color temperature. In lighting, what seems cooler - blue=ice, red=fire, is actually the reverse when it's a part of a beam of light.
2) A double purchase fly system requires half as much or twice as much hand line travel for the same amount of (pipe) travel - over (that required by) a single purchase system?
Twice as much - A double purchase system uses mechanical advantage to make up for a shorter amount of distance the arbor can travel, but requires twice as much rope to move the arbor.
3) Cyc Lights using RSC or more commonly known as recessed single contact/double ended lamps, should not be used vertically, Why?
A normal RSC lamp is base horizontal +/- 15 degrees and any other burning position will leave the filament unsupported.
Here is verbatum from a GE catalog:
"EHZ G.E. #43704 300w Frosted Notes: Burn Horz ±4°"
"EHM G.E. #43703 300w Clear Notes: Burn Horz ±4°"
"FDN G.E. #23734 500w Frosted Notes: Burn Horz ±4°"
"FCZ G.E. #23703 500w Frosted Notes: Burn Horz"
"FCL G.E. #23731 500w Clear Notes: Burn Horz ±4°"
"FDF G.E. #23735 500w Clear Notes: Burn Horz ±4°"
"FHM G.E. #23792 1,000w Frosted Notes: Burn Horz. ±4°"
"FCM G.E. #23797 1,000w Clear Notes: Burn Horz ±4°"
