KTL-T818W1200LR is KENKIO newest independently developed LED Tube. With adjustable delay shut off time and power saving adjustment. Through independent R & D we developed our own passive PIR Sensor utilizing, Japanese Nicera infrared sensor, Fresnel lens, and microcontroller unit (MCU). This internal PIR Sensor have time delayed action, anti-interference, and more accurate sensing capability, detecting distance is 7 metersSelling Point:1) Own Patents, Own Design2) Two Adjuster: one for delaying time, other for lux, no need to change Control Board, no need to change the software to avoid error from software,production, clients also can change it by themself in the future by manual rotation.3) Our delaying time is with 9 levels (from 5 seconds to 60 miniutes), but the max of normal radar tube is 2 miniutes, it is limit4) our end cap can be rotated 180 degree, it is more easy to install different location to detect objective5) our LED Tube already meet the standard of TUV.Two Adjusters as below1. Lux, When user is away from detection zone, light tube will stay on based on the set time.2. TimeLED Tube end cap is rotatable 90 clockwise and counter clockwise
