Also depends on what type of ballast it is. When I had amagnetic ballast it was always very, very hot. I now use an e-ballast that is no where near as hot.

Magnetic ballasts operate with an output (the elec. going to the lamps) of about 60 Hz. Electronic ballasts operate at over 25 kHz. People may notice the flicker of magnetic ballasts, but not of the electronic ballasts. Electronic ballasts usually run cooler than magnetic ballasts. Ballast factor - the lumen output of the lamp and ballast combination compared to the rated output of the lamp on an ANSI reference ballast. Wattage consumed by the combination is approx. proportional to the ballast factor.
---Magnetic ballasts - .94 to .95
---Electronic ballast - .65 to 1.28
Note: lamp life may be reduced with ballast factors greater than 1.18.
