Commercial Greenhouse Grow Lights

Horticultural lighting poses unique problems.  Many commercial greenhouse grow lights are installed using LED lighting or Sodium Lights (High Pressure Sodium Grow Lights -  HPS). Which one is a better solution is a common question.  LED grow lights are rather new to the horticultural lighting world, where HPS grow lights have been around for quite some time. There are grow forums around the world who can debate a pro and con list that will equal at any length.  So often times, commercial greenhouse grow lights are chosen based on past experience.  The horticultural lighting migration from incandescent to fluorescent to high intensity discharge (HID) halogen, to high-pressure sodium (HPS) to LED has taken time; however, renewed interest in energy conservation and novel production is fueling a rapid growth in LED technology.


Commercial Greenhouse Grow Lights – LED grow lights

LED grow lights are without question the most efficient lighting type available resulting in huge savings on your power bill.  LED grow lights emit very little heat which makes them ideal for indoor growers especially those using vertical farming methods.  LED fixtures are manufactured as a single encased fixture which makes them easy to handle and reduces their size making them ideal for tight spaces.  LED fixtures run higher in price than HPS grow lights, but their reduced operating costs pay back in dividends.  Colder climate greenhouses and grow rooms using LED horticultural lighting may need to supplement the heat source of your indoor area to help maintain desired growing temperatures.


Commercial Greenhouse Grow Lights – HPS grow lights

HPS grow lights produce a massive amount of raw light output.  That is the key to their popularity.  This intensity can produce great crop yields which is ideal when working with very large plants.  But this lighting intensity also has the downside of using more electricity, generates more heat which increases costs for maintaining grow room temperatures with the necessity for added ventilation, and HPS grow bulbs often need replacement every 12-18 months.  All of this adds to higher operation costs using HPS as your horticultural lighting solution.


Commercial Greenhouse Grow Lights - CMH grow lights

When making a comparison to HPS on a watt to watt basis, the CMH grow light has been found to have a more balanced, efficient PAR spectrum than HPS lights.  They also have a more natural CRI (Color Rendering Index) generally rated between 80 to 96 CRI - by comparison, the sun is rated at 100 CRI.  For this reason, the CMH is a better single light solution as a commercial greenhouse grow light.  The ceramic arc tube used in the Cermaic Metal Halide light is a very similar material to the HPS grow light.  For this reason the CMH is often said to be a mix between and MH and HPS light.
