Buying tips

  • Match the control’s stated voltage and load rating to the circuit and total connected load; LED compatibility is model-specific.
  • A socket adapter needs an accessible socket and room for the bulb; it is not a replacement for a hardwired photocell.
  • Outdoor controls need the maker’s weather rating and a sensor position shielded from the fixture’s own light.
  • De-energize the circuit and use a qualified electrician for hardwired work, uncertain wiring, or multi-voltage installations.
