Yes it sure is! I’m glad I got one. Quick question, how many watts are lost on a preheat ballast? IIRC, rapid start ballasts lose about 10-15 watts.

NO MORE ELECTRONIC BALLASTS!!!!!!!!!!!!

MAGNETIC BALLASTS FOR EVER!!!!!!!!!!!!!!!

SAY NO TO BULB AND MAGNETIC BALLAST BANS!!!!!

I think it depends more on the ballast itself and less on its starting method. A simple choke ballast should have less loss than a brick magnetic ballast of any starting type. It can also vary depending on line voltage, sine wave, frequency and even the design itself as well as how good the lamps its running are. I'd assume that a brick shaped preheat ballast should have slightly less losses since there isn't any cathode heating coils adding a few watts. Some RS ballasts under the power kut label can turn off the heating voltage to cut down on those extra watts.

I could be wrong somewhere so maybe get a few more opinions from members to be sure
