I'm not an electrician but I can tell you that a 15 amp circuit at 120 volts can handle about 1440 watts with a safety margin already built in. That Mars LED is rated at about 135 watts so you really need two of them to light your space. Add your light wattage to the wattage of the other devices and as long as you're under 1440 total watts, you'll be ok on one 15 amp circuit.
It's always good to use a surge protector for your expensive fixtures and electronics.

Add up all of your watts that are actually used, the led isn’t 300w. Divide watts by volts or use a calculator online, https://www.inchcalculator.com/watts-to-amps-calculator/
You can use a kil-a-watt meter to find actual power draw. But an estimate going by what the manufacturer says input power will be is ok.
Look in your breaker box to find out what your circuit can handle, 15amp is the lowest a normal outlet is. You can run 1440w like @SheeshM said constantly.
I would use a timer that can handle 15 amps (Autopilot Analog on Amazon). If you need an extension cord make sure it handles your amp draw, most will. I might use a surge protector strip also.
