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.
How much is it? On average, a LED light bulb can cost anywhere from $3 to $10 per bulb. While most bulbs come in a single pack, there are multi-packs that contain more than two bulbs. This will all depend on the brand. In the end, plan on spending about $8 or less for a high-quality brand name LED bulb. A smart LED light, which allows you to control it from your Wifi, can cost anywhere from $20 to $45. Aside from the typical white color weâre used to seeing from a light bulb, LED lights can also display an array of colors, ranging from purple to red.
