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.
If you were to replace your 60w incandescent bulbs with a 60w LED (or 20w, even), you would end up with way more light than you were expecting. Wattage only measures how much electricity a fixture uses. Since they are so efficient, T5 and LED require much less energy to produce the same amount of light.
