LED outdoor lights cost less than $2 per year

How much does the electricity cost for low voltage outdoor lights? Here is an easy answer, plus a way to calculate the exact cost of your own outdoor lights.
Here’s a rule of thumb: LED outdoor lights cost $2/year to run from dusk to dawn every night. Yes, that’s all! That’s based on 7W LED landscape lights running an average of 10 hours per evening.
So if you have 10 lights on your landscape, a good guess is they cost $20 per year if you run them from dusk to dawn every night. If you only run them from dusk to midnight, they’d cost even less.
