Watts per square foot. The average LED grow light draws about 32 watts to cover 1 sq ft for flowering cannabis. Compare this to a typical HID fixture which rings in at 40 watts per square foot (assuming a 5â x 5â area, or 25 sq ft coverage area). Using an HID in a 4â x 4â will bring the power coverage up to 62.5 watts per sq ft.
Wattage Wattage is the amount of energy the light uses per hour. In the same family of light bulbs (like incandescents) the higher the wattage the brighter the light is. The disadvantage is that you use more energy. So, if a light bulb is 100 watts, you are using 100 watts of energy per hour.n the same family of light bulbs (like incandescents) the higher the wattage the brighter the light is.
