The roof soffit on the back deck overhangs the wall by about five feet or so. We installed a row of 4" recess baffle cans and a ceiling fan. We kept the recess cans symmetrical along the ceiling and because of that, I was worried that when the fan was rotating, it would give a strobe light effect with the cans right next to it. To remedy this, we put the outside four cans on one switch and the inside two cans on another switch. The fan is switched independently.
