Big Ass Fans’ Powerfoil X LED-equipped industrial ceiling fan delivers as much light as a 400W metal halide, covering the entire diameter of the fan while using less than 175W. Its tempered glass lens is designed to provide excellent optical properties which minimize glare. The light ties directly into an existing lighting grid for simple control. The fan generates huge volumes of gentle air movement using small (1-2 hp) motors, making it an energy-efficient way to cool large areas. The integration of the LED eliminates any need to rearrange lighting grids to avoid a shadowing effect that may occur with very large (8-ft to 24-ft diameter) ceiling fans. The fan directs the light where it’s needed most — beneath it, where people are working.
