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.
Now choosing lights: A typical well built LED downlight provide 80-110 Lumens per watt, letâs consider 100 lumens. So we need total of 20W LED light to get 2000 lumens and 150 Lux for our sample bed room. That means number of LED lights = 20w( total light)/5W(single light) = 4. If you consider florescent tube or CFLs, they provide 60 lumens per watt, but in all directions. So you need more than 35W to get sufficient lighting.
