When you use either the Ring A19 & PAR38 Smart LED Lightbulbs, you simplify your life. These LED bulbs connect to the Ring app so you can manage your household lighting from anywhere. Because these smart LED lightbulbs are so easy to install, you’ll have your lighting system up and running in no time. Primarily designed for outdoor use, each smart LED light can withstand temperatures as low as -4 degrees Fahrenheit and as high as 104 degrees Fahrenheit. However, they’re also great to use indoors. To connect and oversee these bulbs, you’ll need the Ring Smart Lighting Bridge. And, while some lightbulbs emit a variety of colors, these two produce only white light. It may not be what you need for a hoppin’ party but is super helpful to illuminate unwanted houseguests.
