get a multimeter, one with a clamp. and select 1 wire and run it through the clamp, select A or amps. it will measure the amps.
then take the leads on the meter and probe the wall, make sure its set to voltage AC or V with squiggly line next to it. that will give you voltage.
take those 2 numbers and multiply them together, that will give you wattage.
then determine how long you will have it turned on for.
wattage X hours a day X days in a month (X is times). then divide that huge number by a thousand to get kilowatts
then find out what you get charged for kilowatt of power, like 13 cents a KW. multiply price number by the device kilowatt number to get your monthly power usage.

Or just buy a damned KilloWatt and plug whatever you want into it then plug it into the wall and it tells you exactly how much wattage it's pulling.
No way that will do 15 square feet. With blurple LED, you need 50+ watts per square foot for flowering, about half for veg.

By the way i learned the same way you did after i bought the "1000" watt led light everyone on here schooled me on what it actually is so I'll be adding another one right next to it for my next grow..but with that said u did veg and flower 4 plants with it pretty decent size

So if it's actual draw is around 330 watts, every 3 hours your consuming a kilowatt hour. In So Cal we pay around .15 kw hour. 18 hours / day is 6 kw hours @ .15 = ninety cents a day. Don't forget to add in your fan wattage, in a tent you will need ventilation.
