Feature: 1. 1. Different from others, this led grow light added Yellow LED, is beneficial to the synthesis of photosynthetic pigments, promoting energy transmit, improving plant growth quality. It also has universal Blue, Red, IR, UV, White light. Blue and red led are an essential light for all plant growth. Expensive IR UV led can promote plants to defenses mechanisms. 2. 2. The higher light intensity, less lumen depreciation, better lumens and Higher PAR values than ordinary LED chips. The LM301B is the highest light output and full-cycle LED for grow light at present, create more than 40% higher yields with less energy compared with other red blue LED lights. 3. 3. Full Spectrum. Led grow light Full spectrum design, it has universal Blue, Red, IR, UV, White light. Blue and red led are an essential light for all plant growth. Expensive IR UV led can promote plants to defenses mechanisms, promoting plant healthy growth 4. 4. Cooling fans and heat sink constitute an efficient cooling system, keep the environment cool and quiet, plant growth light is safer and has a longer service life. 5. 5. V vander life don't use the led spotlight reflector because the led reflector is not heat‑resistant.
