How switching the LED will save you money

Several years ago, the debate between the benefits of using HPS lights (high pressure sodium) lights or LED (light emitting diode) lights for climate controlled environments may have fallen slightly in favour of HPS, due to ease, familiarity and the low cost profile of HPS. A lot has changed in the last few years, and LED lights have become the clear choice to produce exceptional crops – for a myriad of reasons. 

Read on to learn more about how switching to LED lighting can not only increase your crop yields, and produce healthier plants, but ultimately save you money and increase your organizational energy efficiency.

HPS lights vs. LED lights

While HPS lights can produce intense light, aiding in healthy crop production, this light intensity produces a large amount of heat, requiring ventilation and exhaust in your grow room, especially in the summer months, and increasing your electricity consumption and costs. While many Canadian growers appreciate the increased heat production in the winter months, this heat can be inconsistent and unstable; indoor climate settings should be automated and controlled by reliable and precise HVAC systems year-round.

LED lights have surpassed HPS lights in climate controlled environments. Quite simply, LED lights are brighter, they last longer, and produce less heat. The average quality LED light can provide over 50,000 hours of light for your grow, losing only a fraction of intensity over their lifespan, compared to HPS lights. As a real-world example, our LED lights have an L90 (or Q90) rating of 36,000 to 60,000 hours, which means that the light output will only fall below 90% after the 36,000 to 60,000 hour point in their lifespan. Comparably, most HPS bulbs will dip below 90% output after only 10,000 hours.

HPS lights have become antiquated technology when it comes to choosing lighting for climate controlled facilities; they contain many consumable components that break down easily, and the bulbs can degrade quickly, in turn, affecting your crop yields. 

The graph below shows the rapid decline in traditional HPS light intensity, when compared to LED lights, over the same period of time.

While switching to LED lighting may seem like an increased financial investment, the Gold Leaf Technologies team can provide expert rebate advice, helping you make the move to LED lighting at low or no-cost. We also offer a lease to own model, enabling cost amortization over several years, allowing you to make the updates with little upfront out of pocket expense. Finally, the return on investment when upgrading to LEDs is significant when you factor in saving on energy costs and maintenance over the lifetime of the LED lights.

LED lights are superior to HPS lights in many ways, notably around the longer lifespan and the decrease in heat generation, allowing you to substantially reduce your HVAC and ventilation costs, particularly in the summer months. Plus, you’ll continue to see the benefits of switching your grow to LED, such as:

  • LED lights last 50,000 hours, or more, giving you up to 10 years of light when used under normal operating conditions, helping you produce healthy plants under consistent lighting conditions.
  • LED lights require less ongoing maintenance than HPS lights, which traditionally require annual cleaning or replacement. Many LED lights can actually be sprayed directly, or submerged to clean.
  • You can save on energy, reflectors, ballasts, bulbs, labour and provide more consistent light to your crops.
  • LEDs offer consistent and reliable light, year over year, compared to HPS which begin to degrade quickly after installation. And when your light levels start to drop, so does your crop health and crop yields.
  • There are abundant rebate programs available to Canadians to help you upgrade your lighting, with minimal out of pocket, or explore our lease to own options.
