VEG & BLOOM SWITCH TMLAPY Full Spectrum 1500w LED Grow Light have VEG and BLOOM switch that can be set accordingly to the plant in different stages. The VEG switch is used when the plants are in the germination stage or seedling stage. The BLOOM switch implements more red wavelengths which is most suitable for plants in the flowering and fruiting stages. We recommend that VEG and BLOOM used together in the flowering and fruiting stage for the best results. COB TECHNOLOGY LEDS - COB with higher brightness, smaller thermal resistance, less light attenuation and longer life. Our COB itself is a full spectrum design with high PPFD value which can promote faster and better plant growth. FULL SPECTRUM The COB LED itself is a full spectrum lamp integrated design bead. We did lots of experimentation to ensure that this full spectrum design promotes plant growth. It includes universal Blue Red IR and white light provide everything plant desire in the natural sunlight. COB TECHNOLOGY LEDS COB with higher brightness, smaller thermal resistance, less light attenuation and longer life. Our COB itself is a full spectrum design with high PPFD value which can promote faster and better plant growth. Suitable for all Stages of Plant Growth Germination Stage -For Germination Stage : 32" -45" above the plants, we recommend lighting for 14-18 hours a day. Growing Stage -For Vegetative Stage : 30"-42" above the plants, we recommend lighting for 12-14 hours a day. Flowering Stage -For Flowering Stage: 28" -38" above the plants, we recommend lighting for 9-12 hours a day. Fruiting stage -For Fruiting stage: 28" -38" above the plants, we recommend lighting for 7-8 hours a day. Read more FULL SPECTRUM The actual power is 310 watts! The best hanging height at 20"-36", The core coverage area is 5.3*4.6ft at height around 32". It is more scientifically designed to be more energy-efficient than HPS and MH. Attention -Indoor use only, not water-proof. -The working environment: 20~40℃,45%RH~90%RH. -Stop using light when fans are off. -This led full spectrum grow light include IR LEDs, they look dim, they are not faulty LEDs. -Extremely bright, do not look directly when the light is working.
