Yes you can! We actually recommend that you use an LED bulb with your Smart Security Light or Toucan Smart Socket, but you can also use a standard compact fluorescent bulb, or any incandescent bulb up to 40W (for the Toucan Smart Socket) or up to 100W (for Kuna and Maximus Smart Security Lights).
We recommend a bulb with a maximum of 800 lumens or less to minimize glare. Our tests show the best results from a standard A-15 LED or CFL light bulb, 450 lumens.
