The Kingbrite Quantum Board LED Grow Light - 240W, Lm301H, 3500K, Double Heat Sink lets you grow what you love all year round. This product ensures that your seedlings and plants receive all the necessary light they require to perform photosynthesis regardless of the season, converting the light they capture into sugars necessary for growth. It features highly-efficient white light quantum LED boards and thanks to its Samsung LM301H white light full-spectrum LEDs it achieves better results for vegetation and flowering of plants. Its LED lights give off less heat and are calibrated to meet the needs of plants grown indoors. The Samsung LM301H's feature white full-spectrum light thanks to Epistar 660nm LEDs. These are optimised to give off more blue (cool) and red (warm) light, which are the ends of the spectrum that the majority of plants utilize (with very little yellow and green light used). That's because red light stimulates plants to flower while blue light stimulates the growth of plant foliage and roots.

As a result of the above, LED lights are better for your plants, better for the environment, and hit your wallet for less in the long-term due to how ultra-energy-efficient they are. All of this means you'll be able to grow plants, ensure leaves grow stronger, or make flowers bright and beautiful. Whatever your requirements, the Kingbrite 240W Quantum Board ensures the optimal indoor growing environment for your plants to thrive.
