Explux LED Light Sensor Bulbs with E26 Base, 40W Equivalent, Daylight White, Detects Light In Enclosed Fixtures, and Features a Light-Off

[Detects even sealed fixtures] Using next-generation motion sensor technology, the bulb can detect motion even when it's in a sealed fixture. [Light-off notification function] After automatically turning on for approximately 112 seconds, if no motion is detected during that time, it will enter "Light-off notification mode (approximately 50% dimming)" for approximately 8 seconds. [High brightness] Despite the same size as a standard 40-watt bulb, it delivers a high luminous flux of 600 lux, more than 30% brighter than a standard 40-watt bulb. [Automatic light detection] The built-in brightness sensor prevents unnecessary lighting and saves energy during the day. If the area around the lamp is bright (approximately 30 lx or brighter), the brightness sensor will activate and the bulb will not turn on. [Auto-on/Auto-off] If motion is detected, the bulb will turn on at dusk or at night at a dim light of less than approximately 30 lux. Continuous movement within the range will keep the light on. If you leave the range, the bulb will automatically turn off after a 120-second countdown. When using multiple products at the same time, the installation distance between the products must be at least 1.5m.
