Grow Lights: LEDs vs. High Pressure Sodium Lights
Jul 18, 2019
When it comes to indoor horticulture operations, there are three big things a grower always must get right if they are to succeed and they are water, soil, and light. While every plant requires all three of these to grow and thrive, each plant is different when it comes to how much and what type of each. Here at Titan LED Solutions, what we try to help our horticulture clients with is finding the right type of lighting for their operation and the best system to deliver that type of lighting, and answer all their questions involved in that process. One of the most frequent questions we get is on the difference between LEDs and high pressure sodium lights.
Understanding Grow Lights: LEDs vs. High-Pressure Sodium Lights
First off, for those new-coming growers, grow lights are defined as any artificial light source that either supplements natural light or replaces it altogether in order to enable plants to photosynthesize. Traditionally, high pressure sodium lights have always been the go-to light source when it comes to growing plants. In fact, five and ten years ago there would be no debate among growers that high pressure sodium lights are the best choice for horticulture operations.
But that was ten years ago.
In recent years, the significant advantages of LEDs combined with their decreasing costs (early LEDs and LED systems tended to be too cost-prohibitive for those curious but not sold on the technology) have made them a premier choice in the plant growing world. LED grow lights nicely combine precision spectral outputs and thermal management in order to convert nearly all of its consumed power into light energy that stimulates plant growth. In other words, LEDs can produce significantly greater plant yields while simultaneously consuming less energy and costing less money in their lifetimes. Today’s best LED grow lights are capable of operating at half the cost of their rival high pressure sodium lights. They also are much cooler, giving off less heat and thereby saving growers in secondary electricity costs.
There is also the lifespan to consider. If you are just getting started with a grow operation, then experimenting with different light set-ups will be a natural part of your new business. However, there is also the long-term costs to consider and if you already have a grow operation but aren’t sure whether it’s time to make the switch, then you too should be thinking how long you want your next lighting system to last. A high pressure sodium light will last, on average, about 10,000 hours, which would imply that if you left these lights on for 12 hours a day, you could expect to have them operating for at least two years. In contrast, a rival LED with the same light output will have a lifespan of between 50,000 and 100,000 hours — or 11 to 22 years. That makes it a serious lifetime investment for your business!
