So, I no longer turn off the lamp when I leave the house. It still feels weird though and my parents are probably turning over in their graves. Do you always turn off LED bulbs when you leave a room or the house?
7 watts x 24 hours x 365 days = 61320 watts per year
61320 watts === 61.320 kilowatts per year
61.320 kilowatts x $0.15 per kw = $9.20 per year (if on 24 hours)

Same math for 12 hours = $4.60 per year

I use $0.15 per kw because I also include base fees and other fees. Take total bill and divide by total kw for that number.
