LED grow lights; are more expensive, why are so many people buying LED grow lights today? When you choose high-quality grow lights, your plants will grow better, your electricity bills won't climb, and LED grow lights are better suited to our environment than other types of lighting.
LED lights are solely utilized for supplying brightness inside a commercial or residential sphere. In the meantime, LED grow lights are more conducive to the growth of plants.
How does Led grow lights work?
LED grow lights are luminaires utilizing LED chips in a modern and efficient way to produce light for growing plants.
LED grow lights come in many shapes and sizes but as the most essential units of LED grow lights LED chips to have most of the effect on the quality of the light, i.e. spectrum (colors) and photon flux (“brightness”) produced. Since LED grow light manufacturers can choose the LEDs they use in their lamps, it is important to understand which kind of LED grow light best fits the specific application. One of the advantages of LED grow lights compared to traditional lighting solutions is the ability to match the light to the needs of plants.
2. What is the effect of LED grow lights on plants?
The United States Department of Agriculture (USDA) has determined that artificial lighting accounts for up to one-third of the total cost of indoor plant cultivation. LED lighting produces better quality illumination than traditional grow light systems with less than half of the electrical energy input. Those cost savings can be reallocated to other aspects of a facility’s operations to improve plant growth and yield.
--- Color variations of the LED grow lights are directly connected to the intended purpose.
Adding other colors to the spectrum, such as green, far-red, and deep blue aids this process by giving plants more information about their environment and overall resulting in higher quality plants (quicker growth, more secondary metabolite accumulation, etc). A spectrum that contains all colors is called a full spectrum and mostly resembles sunlight. If it has high proportions of green, the light will appear white to human eyes, and while not a crucial factor for plant growth, it does make the workaround of these lights easier and makes a visual inspection of the plants possible.
--- LED lighting systems can be configured to provide optimum photosynthetic photon flux density.
Photosynthetic flux density (PPFD) refers to the total amount of light that actually arrives at a plant surface. Higher PPFD levels generally translate into better plant quality and higher indoor crop yields. Because LED lighting systems operate at lower physical temperatures than traditional indoor lighting, LED fixtures can be placed closer to plant surfaces to generate those higher PPFD levels.
--- LED lighting produces larger plants and better crop yields.
Indoor cultivation that utilizes LED lighting is superior to crop production that relies on older artificial lighting sources, and in some ways, it may produce more bountiful harvests than outdoor cultivation which is subject to inconsistent amounts of sunshine and variations in weather patterns.
--- LED lighting is durable.
LED grow light system will generate high-quality light for more than 50,000 hours of use. LED lights are resistant to vibrations, shock, and impact from external objects. Their durability makes them ideal for exposure to weather, wind, and rain. They are even strong enough to be a good choice when there is a concern of vandalism, traffic-related impact, or on construction sites
3. What are the advantages of Led grow lights?
LED is worthy of your attention, and here’s the reason:
---Saving Energy - Low Power
LED grow lights are more efficient than traditional lighting systems, consuming 60% less energy to give the same level of light. They emit less heat and provide more usable light than traditional lighting systems. This is because an LED diode does not burn anything to produce light. Due to their reduced energy use and heat production, LED grow lights lower energy bills considerably.
LED grow lights do not give off a lot of heat. This is unlike HID lighting systems that produce temperatures approaching 400 or more degrees. LED grow lights do not give off a lot of heat. This is unlike HID lighting systems that produce LED light and does not much affect the operating temperature in a greenhouse or grow room.
---Recycle & Environment Friendly
LED grow lights are 100% recyclable. Unlike HID lights, they do not contain toxic substances like mercury. To ensure this, all quality LEDs are certified by RoHS.
On the other hand, LEDs do not contain mercury and are considered safe. This is mostly true—they do not contain mercury, but they are not completely metal-free. A 2010 study by the University of California Irvine, found very high levels of lead in low-intensity red LEDs and high levels of copper, nickel, and silver in other colors of LEDs, except for in low-intensity yellow. LEDs are solid-state lighting and the diodes are typically very small so do not risk breaking. Yet, if the diodes end up in the environment and break down, the metals can leach.
LED grow lights can be used 24 hours a day with little effect on temperature. The use of LED lights enables you to change the daylight hours and the amount of red wavelength light at the exact right time to maximize the plant growth rate.
The best-LED plant lights in the marketing produce a balanced full spectrum of light. Spectral manipulation is from the ability to independently control each panel's spectrum. This is a feature unique to LED grow lights. Traditional grow bulbs beam a single spectrum that cannot be manipulated. Many LED grow lights contain an array of colors, typically reds, blues, and whites, that can be turned on or off in any combination depending on the plant’s growth stage or variety/strain.
Most of these lights connect to a WiFi network in which the grower can use a remote to set up the SDS options. Some lights use a smartphone app to control the fixture’s SDS, while other brands have their own remote or controller.
LED grow lights have a lifespan of over 50,000 hours, some manufacturers use LEDs that last up to 100,000 hours or more. which is much longer than traditional lighting systems This is equivalent to almost 10 years of use (at 50,000 hours) or almost 20 years of use (at 100,000 hours), respectively. Compare this to MH bulbs which last an average of 10,000 hours or HPS bulbs which have a lifespan of 16,000 hours or so.
---Easy to Install
At a minimum, small to medium-sized grows only require an LED fixture and ventilation/air circulation. Simply plug in the light, hang it up, and ensure adequate airflow and stable temperatures. Growers don’t have to set up a ballast, hang the reflector, and worry as much about the grow space overheating due to the hot temperatures exuded by an HID bulb.
Return on investment - ROI; there are many factors to consider for ROI that is not related to the direct monetary savings of electricity. Return on investments will vary significantly for growers depending on if they are a small closet grow, a medium-sized home grow, or a large commercial farm.
