The advent of technology has resulted in the use of LED (Light Emitting Diode) grow lights in indoor agriculture and horticulture. LED grow lights have become popular and are gaining wider acceptance than the traditionally used Incandescent grow lights, Fluorescent grow lights & High-pressure sodium lamps. A lot of research has gone into the development of led grow lights.
Plants need only certain colors of spectrum light for about 14 to 16 hours a day to boost its growth. Red light is in the range of 640 nanometers and blue light in the range of 450 nanometers have the greatest effects on chlorophyll production, which plays a significant role in photosynthesis. Red and infrared light makes plants grow tall and thin. Reduction of red and blue light results in improper growth. Orange light has a considerable role in photosynthesis. Other colors of the spectrum are needed only in negligible amounts. It is this feature of led grow lights with specific colors that has resulted in increased acceptance. Red & blue LED lights in the ratio of 2:1 have always been the most effective. Also try driveway lighting, solar patio lights and led deck lights.
High Power PAR38 All Blue 42 SMD LED Grow Light with Standard Screw Base for Cloning and Vegging 110 240 Volt, 1313buLed grow lights have longer life compared to traditional grow lights. They do not have filaments unlike incandescent lamps. Some LED lights come with a shelf life of more than 100,000 hours. Unlike incandescent lamps which produce too much heat, LED grow lights produce light or no heat that has a greater impact on air conditioning costs. LED lights are known to save 55 to 60% of power consumption. They come in as low as 15 or 28 watt diodes. They are cheap in price compared to the other options. Most LED lights are priced at a range of $100 to $2000. Also, there exists a wide variety of LED lights for one to from. LED lights do not require ballast, so they can be easily fit in most houses. This is a great advantage compared to fluorescent lights which require big ballast set ups. The maintenance costs are very low compared to traditional lights.
Led grow lights are being used in Hydroponics, a technique of growing plants in a liquid mixture of nutrients where natural sunlight is not available. Hydroponics using LED grow lights is effective because the lights work on a low voltage that allows them to last long for several years without burning out. Wide angle projection of light ensures uniform leaf formation and coverage. LED lights are available in different colors, of which red and blue lights are highly effective. There are also LED lights that can trigger required colors at different stages of plant growth. Most people use smaller LED lights as they offer higher intensity than the bigger LED lights.
Many companies are manufacturing LED grow lights these days. One such pioneer is Pro-source. Before buying a LED light for your garden, it would be better to consult with a specialist regarding the size and type of the LED lights that you should buy.
