What are LEDs? HPS?
Light-emitting diodes (LEDs) are a type of light source that uses solid-state semiconductor chips to produce light when an electric current flows through them. This allows them to produce more photons (light) while using less electricity than older HID technologies, such as high-pressure sodium (HPS) lights or ceramic metal-halide (CMH) lights.
What is a High-Pressure Sodium Light (HPS)? High-pressure sodium vapor (HPS) lights, similar to LPS lights, are a specific type of gas-discharge light (also known as a high-intensity discharge, HID, or arc light). The principal difference between low and high-pressure sodium lights is the operating pressure inside the lamp.
In this article, we will discuss these 2 types of light for plants growing. The question you may want to know.
Is LED more efficient than HPS? Does LED grow lights yield more? Are they equivalent? How do we conduct the ultimate grow light review? Why do more growers begin to use LED?
About the spectrum
Unlike the single fixed(Dual) spectrum produced by HID (HPS), LEDs come in a variety of colors allowing them to be mixed and matched to create a spectrum of light optimized for plant growth. This results in higher yields as light is being delivered to the plant in a form that is easier for them to use in photosynthesis.
Full Spectrum is light that covers the electromagnetic spectrum from infrared to near-ultraviolet or all wavelengths that are useful to plant or animal life; in particular, sunlight is considered full spectrum, even though the solar spectral distribution reaches Earth changes with time of day, latitude, and atmospheric conditions.
Advantages of LED Grow Lights
1, Energy saving
LEDs use far less energy to produce the same amount of light when compared to HPS or CMH. According to market research, LED lights consume 90 percent less power than HPS grow lights. You have less load on your amperage and electric breakers at home because led grow lights enhance the energy efficiency of your indoor garden. Then you can save on electricity bills.
2, Longer Lifespan
In comparison to HPS lights, LED lights have a longer lifespan. With time, HPS bulbs may become dimmer(become black) and lose efficiency, once the issue appeared, need to replace the whole light. For our led grow light, can last 50,000 hours before its light output is significantly reduced, if there is some issue with led, you can only replace the broken one. So in the long run, LEDs are the more cost-effective lighting solution.
3, Produces Less Heat
Another benefit of LED grow light is that they produce less heat than HID’s. HPS, not only make it less efficient but also creates a number of issues and limitations for indoor grower, causing additional costs for the fixtures to control the temperature.
4, Can Hang Closer to Plants
Since LED grow lights produce less heat, they can be placed closer to the canopy of your plants. HPS/CMH grow lights can burn plants if placed too close to the canopy due to the large amount of heat they produce.
That means you can grow vertically on racks. Multi-level grow operations enable cultivators to grow more plants in less space, reducing their expenses.
Our new SE series with Led Bar design makes good use of this advantage, perfect for vertical rack growth.
