About LED Grow Lights

About our LED grow lights

We've set the new gold standard for seed starting and indoor growing! Our product development team engineered these energy-efficient, economical and effective LED lights to specifically meet the exacting needs of plants (in contrast to multi-purpose LEDs). They deliver the bright, full-spectrum light plants crave, with an additional spike of blue light to stimulate stronger root growth, enhance photosynthesis, and ensure peak growth. We've made this cutting-edge technology available to home gardeners in our premium LED Grow Light Stands. Enjoy your heartiest and healthiest seedlings, houseplants, orchids and other indoor plants! View our full line of LED and Fluorescent Grow Lights and Stands.

3 ways LEDs are a greener way to grow:

  • They’re great for your plants. High-tech LEDs are calibrated specifically for indoor growing. Plants grow greener.
  • They’re super-efficient. LEDs use half the electricity and last 5x longer than fluorescent bulbs. Saves you some green.
  • They’re earth-friendly. Mercury-free LED tubes won’t shatter like glass, so fewer end up in the landfill. Greener for the earth.

What are LEDs?

LEDs (light-emitting diodes) create light when an electric current — a flow of electrons — passes through a special material called a semiconductor. As the name implies, a semiconductor allows some, but not all, of a current to pass through. Crystals made of pure silicon don’t conduct electricity. But when a small amount of an additional substance such as phosphorus is introduced into the crystal, it upsets the equilibrium of the material and activates the electrons inside. When an electrical current is applied to the crystal, some of this activation energy is released in the form of light. NASA pioneered the use of LEDs for growing plants as a result of their research on the best lighting technology to produce edible crops in space.
