The bulbs are particularly useful for indoor/outdoor lights when you're away from your house on vacation or you are gone overnight-they automatically on/off, enhancing physical security.

• Thanks to the dusk-to-dawn sensor technology, it offers an energy-saving solution.
• This bulb turns on automatically when the ambient brightess is insufficient (at dusk or in the night, brightness＜30 lux), and turns off when the ambient brightness is sufficient (at dawn or in the day, brightness＞30 lux). You don’t need to physically turn the light on and off, and it helps to illuminate the night while avoiding unnecessary waste.
• 5W LED light bulb can replace 10W-40W halogen/incandescent, saving 80% on your electricity bills than traditional halogen/incandescent light bulbs.
• Simple installation, screw it like a general E12/E14 LED bulb, leave the switch on and keeping it on. No need a separate light sensor, additional motion detection or sound control fixtures.
• Perfect for courtyard, hallway, garage, pathway and any other places where need to keep lighting all night.

Note:
-Consider the daylight level when it is used indoor.
-Cut off power before replacing, and just leave the light switch on as the bulb will turn on/off by its own when sensor triggered.

-Make sure that there is a certain distance between two bulbs (more than 5 feet), as too dense light can prevent the bulb from working.
-Not application for recessed fixture as the bulb will stay on when it can't sense daylight, but for open light fixture, enclosed light fixture with clear / frosted cover.
-Do not install it on any kind of dimmer / timer / sensor which will override the bulb sensor.
-Not waterproofing, please use it in a place or with a lighting fixture that can protect the bulb from water.
