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.
A Cree LED Lighting product, like the LR6 TM downlight, can replace a 65 watt light while using only 10.5 watts. In its 50,000 hour lifetime it will consume about 525 kilowatt-hours, costing about $63. During that time, it will never need to be replaced. The Cost of Incandescent Lamps. A typical 65 watt light lasts for 2,000 hours. To match the light output and longevity of a Cree LED Lighting downlight, traditional lighting would consume 3,250 kilowatt-hours, and need to be replaced about 25 times, costing over $465. It's a simple story...saving over $400 in electric and relamping costs, for every downlight you replace.
