Putting foil on those box fan blades will help with light reflection as well as air circulation. The fan blades with foil are spinning and reflecting as the light shines, so it is almost like they are blowing light onto the fans. I've heard people say that foil on the blades increases yield up to 70%. I do it to all my fans.
