Features: Auto Sensing This bulb is built-in a PIR sensor and a light sensor, it will automatically turn off in the day time and turn on at night when it senses motions. 12W Motion Sensor Bulb The 12W motion sensor bulb uses high-quality SMD lamp beads,high-brightness,no flicker,no eye hurting. Comfortable Light The color rendering index (CRI)of the bulb is over 80, the higher CRI, the more realistic colors appear to the naked eye. Low Consumption High Brightness Very low heat generating, besides saving light power. Energy-saving and environmentally friendly, is conducive to recycling. Low-energy, high-brightness, energy-efficient light bulbs. All-inclusive Lampshade Light bulbs are fully enclosed lampshades that do not accumulate dust and allow mosquitoes to fly into damaged lamp beads and chips, it is durable and beautiful. Integrated Design Integrated smart IC, safer and more stable, no risk of potential safety hazards due to high temperature flammability of sponge rubber.
