How many tubes are in the fixture? What is their rated
wattage?

Assuming a 2-tube fixture with each tube rated at 40 Watts,
you'll need about (80 Watts) x (12 hours) = 960 Watt-hours of
energy per day to power up that fixture. The cost depends
the going rate of electricity in your location, at the time
you intend to use the lights.
