Dusk to Dawn A19 LED Light Bulbs Outdoor, Automatic On/Off, 60W Equivalent, Warm White 3000K, Energy Efficient 9.5W, 850 Lumen, E26 Base, 4-Pack, HQ-H009

[Dusk to Dawn Auto On/Off] No app or manual control/settings are required. Featuring advanced photocell sensors, these light-sensing bulbs are easy to use in exterior lighting fixtures. Keep the power switch on, and the bulbs will automatically illuminate at dusk and turn off at dawn while adjusting to the surrounding brightness.
Note: These bulbs are non-dimmable. [Energy-Efficient] An advanced smart driver chip automatically reduces energy consumption by 50% after 6 hours of operation while maintaining 70% brightness for the remainder of the night, when less light may be needed. [Work with Frosted Shade and Recessed Fixtures] New-generation sensing technology works with frosted shades, fully enclosed fixtures, and recessed luminaires. With 360-degree light sensing, the sunlight-sensing angle is as wide as the light-emitting angle, so there is no need to worry about the sensing direction when installing the bulb. These bulbs are very easy to install and work well in a recessed luminaire. [Work in Shady Areas] Advanced photocell sensing technology detects faint light even on cloudy days. The bulb will not remain on during rainy days or in shady areas like some other brands' dusk-to-dawn bulbs. [Support Close Arrangement] These A19 light-sensing bulbs can distinguish between their own light and other light sources, making them suitable for situations where two or more bulbs are closely arranged, such as multi-socket post lights and ceiling lights. This helps prevent the bulbs from interfering with each other. This function is exclusive to these dusk-to-dawn bulbs.

The bulbs do not work with bulbs from other brands
