There are many benefits from LED lighting

There are many benefits from LED lighting.  They require less equipment to operate than both HPS lights and MH lights.  Unlike these traditional lamps, the LED needs no ballast, fans or reflectors to operate at optimal levels.  LED bulbs also last longer, up to five to eight years longer than HPS lights. 

HPS lights are also a good choice for plant lighting.  Although they run hot and do not last as long as LEDs, they also have a lower initial cost than many LED Outdoor lighting, and come in blue, red and full color spectrums.

It has been suggested that perhaps a combination of both LED and 1000 HPS lights could produce optimal results.  The 1000 HPS lights would bring heat as a byproduct of the lighting, warming the growing space without the need for the additional purchase of heaters.  The LEDs can add additional blue light as needed.
