1 One Foot: an Ollie where the front foot is kicked forward over the nose of the board. 2  Ollie North: Another name for the ollie one foot.  Boned Ollie: an ollie where the board is dipped down and the legs are practically horizontal, like a Melon Grab but without the skateboarder actually grabbing the skateboard.
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 23 watt LED for instance, can produce the same amount of light (or lumens) as a 100 watt incandescent â and the technology is only getting better! Why LED Lighting (Lumens) Will Eventually Replace (Watts) As improvements in energy and power evolve, wattage will become irrelevant when trying to determine the brightness of a light. Wattage never did a good job predicting the exact brightness of a light to begin with. It was just a guess based off of the power usage.
