Just add up your amp draw. Each of your lights max draw is 2.45 amps @ 120v, 5k btu a/c is around 5 amps @ 120v, 10k btu is around 10 amps @ 120v, dehum's are generally just under what a/c uses. Add it all up and stay under the breakers rated amps. If your using 220/230/277v amp draws are even less. Watts is converted to amps with the voltage number and a Ohm's law converter. Watts are used in sales propaganda for example,,, 300 watts looks more impressive than 2.455 amps.
Or the old people are stupid 1200 watt hair dryer in reality is more like 10 amps
or the 1500 watt space heater is more like 12 amps. All your devices should have the max amp rating on them. If there not clearly marked they need to be in a
trash can. Electricity is easier to work with than nutrients.
