Broco Plant Grow Light, 25Pcs/Pack 3W Full Spectrum 380nm-840nm Wavelength Led Plant Grow Light Chips Hot(With aluminum substrate)

Features: Our led grow chips are made of high-quality and environmental-friendly material, non-toxic, safe and durable to use. Super brightness, high stability, excellent energy-saving effect and they could work for a long time up to 50000 hours if their working temperature is less than 70℃. Full Spectrum led chips and the wavelength is 380nm~840nm, suitable for all stages of plant growth, so they could make your plants grow thrive in night or even under the dark environment. Aluminum PCB has good features of heat dissipation, when the LED chip is fixed on aluminum layer of aluminum base PCB, the heat from chip can be spread out through aluminum layer rapidly.  Specifications: Condition: 100% Brand New Power: 3W Voltage: 3.2-3.4V Current: 700mAWavelength: 380~840nm Beam Angel: 120 degree Working Temperature: -20~+70℃ Lifespan: 50000HPCB: With 20mm PCB, Without PCB (Optional) Each PCB Diameter: Approx. 2cm / 0.8inch Each Led Chip Size(Dia x L): Approx. 0.8 x 1.5cm / 0.3 x 0.6inch Quantity: 25pcs/pack Weight: Approx. 15g(Without PCB), 40g(With PCB)Package Included: 25 x LED Grow Light Chips Please Note: 1. For eyes safety, please do not look the Lighting chips directly. 2. Because of the heat release of high power LED is large, the heat dissipation of our led chips by aluminum PCB is not enough, so it must be equipped with a cooling device, otherwise the led chips will be weakened or damaged. 3. In order to make sure the led chips could be worked for a long time, we suggest to use constant current power supply and let it work in a temperature below 70℃.
