Import 50w Ufo Led Grow Lights — Buy in Bulk from Supplier in China

The 50w UFO LED grow lights from Ledsun Technology Ltd. deliver a full light spectrum across red, blue and white LED channels within a disc-shaped form factor designed for close-proximity plant canopy deployment. At 50 watts total draw, the unit targets replacement of legacy HID or fluorescent grow lamps in applications where heat management and energy efficiency take priority over maximum photosynthetic photon flux density. The compact geometry suits vertical racks, grow tents and greenhouse benches where headroom is constrained. Ledsun Technology operates from Baoan District, Shenzhen, positioning the supplier within the Guangdong LED manufacturing corridor.

UFO-format fixtures typically integrate an aluminum heatsink body with either passive convection fins or an active cooling fan array to maintain LED junction temperatures below manufacturer limits. Standard 50W class grow LEDs achieve photosynthetic photon efficacy ranging from 1.8 to 2.7 micromoles per joule depending on diode bin quality and driver efficiency. The red and blue channel ratio varies by target crop, with vegetative stages favouring blue-weighted spectra around 400 to 500 nm and flowering stages requiring red dominance near 660 nm peak wavelength. White LEDs broaden the spectral output for human visual assessment and supplementary green light penetration into lower canopy layers. Thermal management design, whether via extruded aluminum or fan-assisted airflow, directly impacts lumen maintenance and spectral stability over operational life.

Buyers range from commercial hydroponic operators and greenhouse managers to home gardening enthusiasts and educational biology departments. The 50W rating suits small to medium coverage areas, with typical flowering footprints of 60 cm x 60 cm to 80 cm x 80 cm at recommended mounting heights. Ledsun Technology carries harbor trust tier status with no response rate data available. The listing does not specify minimum order quantity, unit pricing, lead time or whether the quoted 50W refers to LED draw or total fixture consumption including driver losses. Buyers must confirm these parameters directly with the supplier.

Ledsun Technology Ltd. maintains its registered address at 5F, C8 Building, Gonghe Zone 10th Industrial Village, East 1st Road, Longhua Town, Baoan District, Shenzhen, 518108, Guangdong Province, China. The supplier holds harbor trust tier status on the platform with zero recorded response rate and no average response time data. This absence of engagement metrics indicates buyers should initiate contact through multiple channels and allow ample time for reply rather than expecting rapid turnaround on quotations or technical queries.

The company positions itself within the LED grow light segment, targeting horticultural and indoor gardening markets. Their product description mentions ISO and CE certifications for safety and performance, though no certificate numbers or issuing bodies are provided. No information is given regarding factory floor space, production capacity, R&D staff count, annual revenue, or named OEM or brand clients. The listing also does not state years in operation, whether Ledsun manufactures in-house or sources from upstream factories, or the extent of their quality control processes. Buyers should request a company profile, factory audit report, or third-party verification documents before committing to volume orders.
