according to the google gods ...
Light sources. Metal halide (M-H) has become the lamp source of choice for arena event lighting systems. This lamp source is significantly more efficient than incandescent sources and renders colors more effectively than high pressure sodium (HPS) sources. M-H lamps have a flicker factor of less than 0.1, reducing the undesirable stroboscopic effect, which is particularly noticeable during slow motion replay television broadcast.
M-H lamps are available in color temperature ratings from 3200K to 5600K, and with color rendering indexes as high as 70. M-H lamps may be operated with instant-restrike type systems; however, evidence of superior field experience and a minimum five year warranty is recommended in considering the use of this type of control.

Color Temperature Light Source
1000-2000 K Candlelight
2500-3500 K Tungsten Bulb (household variety)
3000-4000 K Sunrise/Sunset (clear sky)
4000-5000 K Fluorescent Lamps
5000-5500 K Electronic Flash
5000-6500 K Daylight with Clear Sky (sun overhead)
6500-8000 K Moderately Overcast Sky
9000-10000 K Shade or Heavily Overcast Sky
this is a pretty good explanation that doesn't get too geeky.
