USB Grow Lights

Blue and red color spectrums are the two most beneficial color wavelengths to assist with cultivating healthy plants. This 18 Watt USB Indoor Plants LED Grow Light was designed to maximize the amount of quality light absorbed by growing plants.

  • Input Voltage: DC 5V
  • LED Quantity: 36 pcs(24 Red & 12 Blue)

  • Timing Function: 3h, 9h, 12h
  • 3 Lighting Modes: Deep Red Light, Dark Blue Light, Red & Blue Mixed Mode 
  • Deep Red LED (630nm): Plants are particularly partial to large doses of red light. Red wavelength allows to create a plant hormone that prevents the breakdown of chlorophyll, in turn, keeps plants lush and green longer. Plants that receive large doses of red light will be able to grow strong during the flowering stage
  • Dark Blue LED (460nm): Dark blue wavelengths are important during the vegging stage of the plant growth cycle that will grow healthy side stems and stay shorter/grow wider. The blue light will diminish the auxin, a plant hormone which can cause plants to grow tall and spindly, with the Dual Band LED panel growers can ensure plants receive enough blue light all year round.

In addition to maximizing the growth of plants, the  18 Watt USB Indoor Plants LED Grow Light has been engineered for greater energy efficiency. The 50,000+ hour lifetime offers years of quality usage without having to change over bulbs.
