This 600mm (2ft) 9W T8 LED Tube with a Radar Motion Detection is perfect for replacing fluorescent tubes of up to 20W. Its SMD3014 light source offers a 900 lumen brightness within a 160º beam angle. It comes in a translucent cover that diffuses the light and reduces glare. It also has a 30,000 hour working life. Thanks to its radar sensor, this 600mm (2ft) 9W T8 LED Tube with Radar Motion Detection turns On when it detects movement within a 180º beam angle and at a distance of 8 metres. The tube turns Off when it detects no movement within its radius, and once approximately 30 or 40 seconds have passed. The radar sensor offers high precision, range and can be used inside closed luminaires. Enjoy the most efficient lighting with this 600mm (2ft) 9W T8 LED Tube with Radar Motion Detection / Turns OFF, available here at LEDKIA, our online lighting shop. The 85V-265V AC Multi-Voltage refers to peaks and drops. The tubes cannot continuously function at these voltages. *T8 LED Tube Install
