Import 4ft Microwave Sensor 18w Led Tube Light — Buy in wholesale FOB from Supplier in China

The 4ft Microwave Sensor 18W LED Tube Light from Greatwall LED Light Co., Ltd. is a presence-activated luminaire built around a 18W LED engine and a microwave motion sensor for automatic on/off control. The unit measures L1198 by 30mm, fitting standard 4ft fluorescent retrofit spaces without modification. Construction pairs an aluminum heat-dissipation chassis with a polycarbonate diffuser, balancing thermal management against mechanical durability. The microwave sensor detects movement through materials such as glass and thin partitions, extending its utility beyond line-of-sight PIR alternatives. Input voltage and driver compatibility should be confirmed with the supplier, as these are not stated in the source data.

The aluminum and polycarbonate material selection reflects standard practice for commercial LED tubes, where aluminum draws heat from the LED board and polycarbonate provides impact resistance and optical diffusion. The 18W rating positions this tube as a direct replacement for legacy 36W fluorescent T8 lamps, with typical efficacy expectations in the range of 100-130 lm/W for this product class depending on LED package and driver efficiency. Microwave sensors at 5.8 GHz are the industry norm for this sensor type, offering detection through obstructions and reduced false triggering from temperature differentials. The 1198mm length corresponds to the nominal 4ft dimension minus end-cap tolerances, a standard that should be verified against the buyer's existing fixture spacing.

Typical applications include corridors, stairwells, warehouses, car parks, and restrooms where occupancy is intermittent and energy savings from automatic switching justify the sensor premium over basic LED tubes. Buyers should confirm the sensor hold time, daylight threshold, and detection range with Greatwall LED Light Co., Ltd., as these parameters determine payback period and user satisfaction. The supplier operates from Guangdong Province, a region with dense LED component and finished-goods manufacturing, which may support shorter customisation cycles than inland alternatives. Packaging, MOQ, and lead time are not specified and must be requested directly.

Greatwall LED Light Co., Ltd. maintains its registered address at Greatwall Industrial Park, Xinxu Town, Hui Yang, Hui Zhou, Guangdong Province, China, 518023. The supplier's trust tier is listed as "harbor". The response rate is shown as 0.00% with an average response time of 0 hours, which indicates no response data is available through the platform signals. No information on factory size, year of establishment, revenue, employee count, or specific client references is present in the source material, and none should be assumed.

The listing presents the company as a manufacturer of LED tube lighting with sensor integration, based in one of China's principal LED production clusters in Guangdong. Buyers should verify factory audit status, ISO certification claims, and whether the microwave sensor module is sourced internally or from a specialised sub-supplier. The absence of response metrics suggests direct contact is essential to gauge communication reliability and technical support capability before committing to volume orders.
