King Brite 480W LM301H QUANTUM...

Allow your plants to thrive in the most optimal indoor growing environment with the Kingbrite 480W J Series Quantum Board. It features a 480W quantum board, Samsung and Epistar LEDs, a Mean Well power supply, larger heatsink, and a dimmer switch.

Keep your flowers growing at a steady rate with the Kingbrite 480W J-Series Quantum Board Grow Light. LED grow lights are the latest way to grow your seedlings and plants, regardless of the season. The J-Series Quantum Board ensures that your seedlings and plants will receive all the necessary light they require to perform photosynthesis regardless of the season, converting the light they capture into sugars necessary for growth.

By using a combination of Samsung LM301H and Epistar 660nm, IR 730nm and UV 395nm LEDs, Kingbrite has created a quantum LED board that can collectively produce the full spectrum white light that is essential for plant photosynthesis, vegetation growth, and the flowering of plants indoors. They’re optimized to give off more blue (cool, stimulates foliage and root growth) and red (warm, stimulates flowering) light, which are the ends of the light spectrum that most plants utilize during the growth cycle. This combination results in a product that is cost effective in the long run while providing quality lighting, reliability and peace of mind to those starting out on their growing journey.

The Kingbrite 480W J-Series Quantum Board Grow Light is powered by 2x Mean Well HLG-240H-48B power supplies and the lights are kept passively cooled by a 4mm thick aluminium heatsink. It also features a dimmer switch so you can easily adjust the brightness of your LEDs depending on your current work environment and requirements. A mounting kit with hang wires are also included with an adjustable cable to slightly adjust the height for the perfect coverage.

The Kingbrite 480W J-Series Quantum Board Grow Light is optimised for growing a variety of plants indoors, ensuring leaves grow stronger or flowers become bright and beautiful. Whatever your requirements, this product provides the optimal indoor growing environment for your plants to thrive.
