The Semigrow ES Series LED grow light is well constructed, very lightweight, easy to use, and very silent. This is because it doesn’t come with fans and built-in heat sinks.it has more colour and wavelengths lights, which include 3500k, 5000k, 660nm and 730nm. 

These make up a sunlight spectrum with all colours included. So your plants will get everything that they want in natural lighting and produce the best yields possible. Quantum board LED is a newer alternative to the more expensive COB grow lights. The quantum board is a large circuit board in which a string of LEDs are connected forming “intelligent spectrum string” resulting in a broader spectrum and bigger plants.
