From HPS to LED Growlights

Why You Should Consider Switching from HPS to LED Grow Lights?


If you are a grower who is still using high-pressure sodium (HPS) lights for your indoor or greenhouse cultivation, you may be wondering if it is worth switching to light-emitting diode (LED) grow lights. LED grow lights have become increasingly popular in recent years, as they offer many advantages over HPS lights in terms of energy efficiency, environmental control, crop quality and profitability. In this article, we will explain some of the main reasons why you should consider making the transition from HPS to LED grow lights for your grow operation.

Energy Efficiency


One of the most obvious benefits of LED grow lights is that they consume much less electricity than HPS lights. Studies have shown that implementing LEDs in an operation previously lit by an HPS system reduces lighting energy consumption by between 40-60%1. This means that you can save a lot of money on your electricity bills and reduce your carbon footprint by using LED grow lights. LED grow lights also have a longer lifespan than HPS lights, which means that you do not have to replace them as often and save on maintenance costs.


Environmental Control


Another benefit of LED grow lights is that they produce less heat than HPS lights. HPS lights emit around 80% of their energy as radiated heat, which can raise the temperature of the grow space significantly and require additional cooling and ventilation systems1. LED grow lights, on the other hand, emit only around 10-15% of their energy as heat, which can be easily dissipated by heat sinks or fans2. This means that you can have more control over the temperature and humidity of your grow space and create optimal conditions for your crops. LED grow lights also allow you to adjust the light intensity, duration and spectrum according to the needs and preferences of different crops and stages of growth3. This can enhance the photosynthesis, growth and development of your plants and improve their yield and quality.

Crop Quality


Another benefit of LED grow lights is that they can improve the quality of your crops by influencing their morphology, physiology and biochemistry. LED grow lights can produce a wider range of wavelengths than HPS lights, which can affect the color, shape, size, taste, aroma and nutritional value of your crops4. For example, red light can stimulate flowering and fruiting, blue light can promote vegetative growth and branching, green light can penetrate deeper into the canopy and enhance leaf development, and far-red light can induce flowering and increase biomass5. LED grow lights can also reduce the incidence of pests and diseases by enhancing the plant’s resistance and immunity6. By using LED grow lights, you can produce higher quality crops that can meet the demands and expectations of consumers and markets.



The final benefit of LED grow lights is that they can increase your profitability by reducing your operational costs and increasing your revenues. By using LED grow lights, you can save on electricity, cooling, ventilation, maintenance and pest control costs. You can also increase your revenues by producing more crops per unit area, extending your growing season, increasing your crop quality and diversifying your crop portfolio. According to a study by Medicgrow3, switching from HPS to LED grow lights can increase your return on investment (ROI) by up to 300% in three years.


As you can see, switching from HPS to LED grow lights can have many benefits for your grow operation. You can improve your energy efficiency, environmental control, crop quality and profitability by using LED grow lights. However, before making the transition, you should consider some factors such as the initial investment cost, the compatibility with your existing infrastructure, the optimal light recipe for your crops and the availability of technical support.
