PS. I have one in my barn that is on 24/7. It uses 9 watts. Just a
dim light for my horses to see where they are at night. That uses 216
watts per day...

You mean 9 watts of power x 24 hours = 216 Wh, ie 0.216 kWh of energy.

(one of these days I am going to put a light sensor on that thing
so it turns off during the day).

A motion detector with incandescent bulbs might use less energy.
