4' T8 shop light pulling too many watts?

[ConstantGreen]

I have several 4 foot shop lights from home depot that take two T8 fluorescent bulbs. The bulbs I'm using are 32w daylight. So each light should be drawing about 64 watts. However, when I plug them into a watt meter they read 190 watts! How is that even possible? Is the meter wrong? Any ideas?

Could be a bad ballast. Or a surge on startup by the ballast. What are you getting that read from? Are they the old magnetic ballast?

Thank you for helping, I'm stumped.

It's the Lithonia 1242ZG. "Standard with residential HPF (High Power Factor) electronic ballast (120 volt, 60Hz)"

I'm getting the reading from an AmWatt appliance load tester. Goes from 0 to 190w and stays flickering +-1 from there. I've measured 3 ballasts, all are giving this high reading.

Okay, the meter I was using must be bad. I sometimes forget I have an APC 1300. I plugged the light into the meter and the meter into the APC 1300. Got a much more accurate readout from the APC, about 50w; yet 175 on the AmWatt. Still confused what's causing the difference tho.
