i read a study somewhere and when they tested different mh lights and ballasts most used huge ammounts of energy when starting up and while running,electronic ballasts ran at proper levels but i dont think the starting up was any better,im thinking of buying a kill-a-watt so i can test things myself and know for shure instead of just guessing all the time.
i have no proof myself but i would shure assume any mh light system is gonna use a heck of alot more power than a t5 of similar wattage

watts is a measure of power so there is no way 100w of mh could be more than 100w of T5... 100w is 100w of power, and yes there is a surge of power when a coil and core ballast is first turned on but its only for a very short time and wont increase your overall power consumption noticibly as it only lasts a fraction of a second.
a kilo watt meter wont show you a startup spike a sits too fast to see, you can make your own wattmeter with 2 multi meters by attaching a ammeter in series with the ballast and a voltmeter in parallel then multiply the values together gives you watts
Amps X Volts = Watts.
