Our house has a "smart switch" on the porch, and it's smarter than me. I couldn't figure out how to program it to turn on in the dark and turn off in the daylight (the sensor is on a pole in the yard). Plug them into outlets, just leave the switch on and forget it. Bright daylight spectral light (may be a little bluish for some people who prefer soft white light of 2700K, which is equivalent to 5000K).
