Instructions for Use and Precautions:

  • Avoid applying heavy pressure to the fixture, otherwise, it will affect the stability of the product.
  • Do not look directly at the light when the fixture is working. The glare of the fixture may harm your eyes.
  • Please use the product within the specified input voltage range according to the specification.
  • Non-professionals must not disassemble the product.
  • After opening the package, please check carefully whether the item is complete. If there is any damage, please contact the supplier immediately and do not use it yourself.
  • Please take care to ensure that it is effective to prevent rainwater from entering the wiring, so as to avoid damage to the fixture of cause a safely accident.
  • It is strictly forbidden to operate with electricity during installation. The installation must be carried out by professionals or under the guidance of professionals.
  • The lamp will heat up during use. It should not be wrapped with flammable or explosive materials or close to the lamp, causing unnecessary accidents or damage to the lamp. Do not use any part of the body to directly touch the lamp to avoid burns.
  • Before the lamp is removed and replaced, it must be powered off and disassembled under the guidance of a professional.


  • Apply to plant factory and growth chambers
  • Suitable for full-cycle planting of cannabis, effectively shortening the plant growth cycle


  • Full-spectrum, high-quality LED chips, the spectrum can be adjusted as needed
  • Generally applicable, saves 40% less energy than traditional HPS lamps
  • Modular design, the lamp shell is made of high purity aluminum alloy, solid structure and excellent in heat radiation
  • Surface oxidation treatment, stainless steel fasteners, strong corrosion resistance
  • PC lampshades, higher transmittance. better strength
  • Simple in appearance, thin and light, collapsible, simple, and various installation modes

Compared to regular open HPS/MH solutions 645W LED grow lights can achieve 30-40% less HVAC capacity.
