I don’t think bulbs use a whole lot of energy these days. A 10W LED bulb would cost $14 per year to run constantly (US pricing). An old 60W bulb would be $83 per year in comparison.
Huh, that’s actually more expensive than I’d have thought for a single bulb, even taking into account that you’d probably only be running it for a quarter of the time

Math:
LED bulb power = 10W
Electricity cost in US = $0.161 per kWh
Running 1 bulb 24 hrs a day = 0.24kWh
Price per day = $0.038
Price per year = $14, running 1 bulb constantly
