HUIERLAI Radar Motion Sensor A19 LED Bulbs - 27W, 3375LM, 250W Eq, AC85-265V, Dusk-to-Dawn Outdoor Light (2 Pack)

Effortless outdoor illumination with radar sensing

The HUIERLAI Radar Motion Sensor A19 bulbs blend modern sensing technology with reliable brightness. When power is first applied, the bulb stays on for 3 seconds, then settles into normal operation. In daylight, the light remains off; when ambient light falls below about 6 lux, the sensor activates on movement and keeps the light on as long as motion is detected.

After motion stops, the bulb automatically turns off about 30 seconds later, helping save energy while still enhancing safety around porches, entryways, or garages. The 2-pack is designed for easy replacement in standard E26/E27 sockets and is suitable for outdoor use in covered areas with AC85-265V operating voltage.

What you gain with HUIERLAI radar motion sensor bulbs

• Broad radar-based detection that works through typical obstructions, offering a wider sensing range than many PIR options.
• Automatic dusk-to-dawn operation: lights activate only in low-light conditions (below 6 lux) for energy efficiency.
• Bright 3375 lumens from a 27W LED bulb, delivering strong, uniform illumination to improve visibility.
• 360-degree detection with a robust range of 16.4–23 feet depending on installation height, providing broad coverage.
• Automatic ON when movement is detected at night and OFF after 30 seconds of inactivity.
• Long lifespan and warranty: up to roughly 35,000 hours of service with a 3-year unlimited warranty.

Tips for best results and installation

• Keep the power on at all times; avoid using with touch, infrared, or voice controls for optimal performance.
• Place the fixture at a height or angle that maximizes motion detection while minimizing false triggers from nearby branches or fences.
