One tube has a power consumption of 36 Watts (or similar).
So running it for 12 hours uses 432 Watt hours, or 0.432kWh.
Over a (30 day) month, it would use 12.96kWh. In England, on
a standard sort of account, 1kWh costs 8.09 pence (0.0809
pounds) so the total is 1.05 pounds per month.
Convert to dollars and allow for your local electricity charge
as required.
