Import 300w Led Grow Lights For Indoor Greenhouse — Buy in Bulk from Supplier in China

Twilight Group Co., Ltd. supplies a 300W LED grow light built around 144 individual 3W diodes arranged in a metal shell with constant current power supply, designed for indoor greenhouse deployment across all growth phases. The unit accepts an input voltage of 85-265V, making it compatible with electrical systems in any country without transformer or ballast. Six internal fans manage thermal output, and the rated LED lifespan exceeds 50,000 hours under standard operating conditions. The grow light is offered in multiple spectral ratios (typical configurations include 8:1, 7:2, and 7:1:1 red to blue to orange/white) with specific wavelength availability at 620-630nm and 660nm for red, and 450-460nm and 460-470nm for blue, allowing growers to match emission to crop photomorphogenic requirements.

The diode architecture uses high-power 3W LEDs chips rather than lower-wattage surface-mount alternatives, a construction approach that concentrates photosynthetic photon flux density (PPFD) and reduces fixture count per cultivation area. Spectral tuning targets the McCree curve: red wavelengths drive flowering and fruiting through phytochrome Pr to Pfr conversion, while blue wavelengths support vegetative growth via cryptochrome and phototropin activation. The manufacturer states the fixture can replace a 600W-800W high-pressure sodium (HPS) equivalent while drawing substantially less power, though actual equivalence depends on canopy height, reflectivity, and target daily light integral (DLI). Thermal management relies on active convection through the six-fan array rather than passive heatsink dissipation alone, a design that requires clean intake air and periodic maintenance to prevent dust accumulation on impeller blades.

Target buyers include commercial hydroponic operations, vertical farming ventures, greenhouse retrofit projects, and research institutions requiring controlled-environment agriculture (CEA) lighting. The fixture suits both soil-based and soilless cultivation systems. Standard packaging ships two units per carton with dimensions 560 x 405 x 340mm and gross weight of 19kg per pair. Buyers should confirm with Twilight Group Co., Ltd. whether CE marking documentation is available for their specific import jurisdiction, and whether the quoted spectral ratios are fixed or customisable per order. The supplier's response rate is currently recorded at 0.00, so direct enquiry through multiple channels is advisable before committing to volume procurement.

Twilight Group Co., Ltd. is headquartered at 3rd Floor, Building F, Guancheng Hi-tech, No. 37 Zhenxing Road, Lou Village, Shenzhen 518100, Guangdong Province, China. The supplier holds an 'imported' tier classification and a 'harbor' trust designation within the marketplace system. Their registered response rate is 0.00 with an average response time of zero hours recorded, which indicates no recent engagement through the platform messaging channel. This does not preclude active trading through other communication methods, but buyers should factor this into their due diligence timeline.

The company profile does not disclose year of establishment, production floor space, employee count, annual turnover, specific client references, or third-party audit certifications beyond the CE marking mentioned in product documentation. The address places the supplier in Shenzhen's Nanshan-adjacent technology corridor, a region with dense LED component supply chain access. Buyers seeking verification of manufacturing capability rather than trading-only status should request factory audit reports, original design manufacturing (ODM) references, or video walkthrough documentation before placing substantial orders.
