What Are Grow Lights?
The name itself symbolizes that grow lights are artificial lights which are designed for uninterrupted growth and nurturing of the plants in the absence or lack of sunlight.
Grow lights either produce a particular range of light or full spectrum light as in sunlight for starting seeds, indoor plants and greenhouses, flowering and vegetative plants, or for all phases of plant’s life.
How Many Types are Available
The technology has successfully tapped the sunlight energy in the form of grow lights. These lights can broadly be classified as follows – Fluorescent grow light, High-Pressure Sodium grows light, Metal Halide grow light, LED Grow Lights, and Incandescent grow light.
Fluorescent grow light
Fluorescent lights come in many variants, the standard version is best suited for vegetable and indoor herbs ( around shelf life of 20,000 hours approximately) while the smaller compact version is used for growing larger plants (around 25,000 shelf life of 10,000 hours approximately).
The biggest disadvantage of the Fluorescent lights is the distance between the light and the plants –at a distance of only 5 inches. Handle with care – being very fragile, you have to be careful while handling fluorescent lights.
LED grow lights are better since they are very handy at a distance of 10’’ to 20’’
Metal Halide grow light
Metal Halide bulbs lights require ballasts, additional circuitry to hold the bulb. Initially manufactured with blue spectrum, these light are now being manufactured having the color temperature as required, ranging from 3000K to 7000K, even 10,000K.
LED grow lights do not require any additional circuitry for support.
High-Pressure Sodium grow light
Ideal for the greenhouse, they produce red visible light along with a minimal amount of other visible light. The red visible light produces considerable heat and requires additional cooling equipment. Also, the generated heat if not controlled, can attract insects and cause damage to plants.
On the other hand, LED grow lights, are cooler as they emit minimal heat; also, they produce light wavelengths suited to the requirements of the growth of the plant.
LED Grow Lights
L.E.D. stands for light emitting diodes, so LED grow lights are the equipment consists of many small optical diodes that emit light. With this construction of LEDs, this equipment can be manufactured to emit any range of light required. For instance, they produce concentrated wavelengths, either red light or blue light, or even a combination of both.
Led grow lights produce less heat and thereby reducing the transpiration of plants, so you don’t have to worry about frequent watering of plants. Moreover, the best LED grow lights are ideal for plants requiring more humidity.
The LED grow light do not require ballasts and have a shelf life of approximately 25,000 hours, much more than its’ other counterparts.
Incandescent grow light
Incandescent bulbs aren’t the grow lights in the true sense, but they can be used for highlighting the indoor plants. These bulbs emit red-yellowish light. Some bulbs which are sold as “grow lights” come with a blue coating, so as to reduce the red light they emit. Obviously, these grow lights produce more heat than light and have a short lifespan.
On the other hand, LED grow lights are much superior in both life expectancy and energy consumption.
History Of LED
LED stands for Light-Emitting-Diode is a source of light when an electric current acting on it. Known since the betimes years of the 20th century, LED technology is constantly evolving.
These early LEDs only emit very weak light and monochromatic; in addition, high. The performance is high. Nowadays, Through many improvements, LEDs have confirmed their position with great capacity lighting, glowing multicolored and high performance. besides the glowing, LEDs are also used in many other fields. For example infrared LEDs in the control equipment, signal lights, decorations and LED grow lights.
An operation of LEDs based on semiconductor technology. In blocks semiconductor diodes, electrons transfer from a high-energy state to a lower energy level and this difference energy emitted into the different types of light. The color of the LED depends on compound semiconductors and characterized by the wavelength of the emitted light.
Semiconductor light-emitting diodes were first known in 1907 by the British experimenter HJ Round at Marconi laboratory he experimented with crystal SiC (silicon and carbon). Later, the Russian scientist Oleg VladimirovichLosev created the first LED. Later, studies have been forgotten due to the lack of practical applications. In 1955, Rubin Braunstein discovered the infrared emission by compounds GaAs (Gallium and Arsenide) and some other compound semiconductors.
1961, two experimenters Bob Biard and Gary Pittman working at Texas Instruments, found that GaAs compound emits infrared rays when electrical current impact and then Bob and Gary are patented infrared light-emitting diodes.
Red-light LEDs was first developed in 1962 by researchers Nick Holonyak Jr. sciences. while he was working at General Electric Company. Then he moved to the University of Illinois where he met the father of radiation-emitting diodes, M. George Craford. George was the one who invented the first yellow LED that emitted the light intensity 10 times compared with the red and orange LED in 1972.
In 1976, T.P. Pearsall has created high-performance LEDs have important implications for the field of optical fiber communication.
The first practical applications of light emitting diodes are that they are widely used for replacement of the incandescent bulb. Diodes are also used in the manufacture of LED 7 bar and later apply in television, radio, telephone, calculator, clock.
Initially, the red LED glow only enough to serve the purpose of observing, the light they emit is not enough to illuminate an area. Then, when LED technology developed, the glowing performance of LED increased significantly. Especially the invention and development of high-power LEDs have met entirely for lighting.
How does it work?
Like other conventional diodes, LED consists of two type semiconductor layers p and n fit together. P-type semiconductor (anode) contains many holes tend to move diffused to n-type semiconductor (cathode), at the same time the p-type semiconductor receives electrons from an n-type semiconductor, As a result, p-type has negatively charged and n-type has positive charged. At the surface of the junction between two semiconductors, electrons are absorbed by holes and tend to go nearer and combine to create neutral atoms. This process releases energy in the form of light photons.
The wavelength of the emitted light depends on the molecular structure of semiconductors. If this wavelength in the range from the infrared to the ultraviolet the infrared, our eyes can perceive that the color of the light.
Why Should You Choose The Best LED Grow Light for your plants
Based on the above discussion, we can summarize the various characteristics of the grow lights as in the table given below.
|Type of Grow Light||Shelf Life (in hours)||Efficiency|
|Led||50.000 – 100.000||40-80%|
|High-Pressure Sodium||10.000 – 24.000||30-40%|
|Metal Halide grow light||6.000 – 20.000||25%|
The above summary shows that LED grows lights are superior and effective to its counterparts having the following qualities.
Light for Every Stage of Plant
LED grow lights produce light which meets the plants’ requirements, at every stage and for every type of plant. You can find LEDs for starting seeds, to LEDs for flowering and vegetative plants, also for greenhouses and indoor.
Longer Shelf Life
LED grow lights’ shelf life is nearly 10 times more than its incandescent and fluorescent counterparts. Although the cost of LED grows light may seem a bit higher, but the fact that the best LED grow lights can be used all year round, the versatility in usage, and shelf life cover up the initial investment in LEDs.
LEDs are cool lights
LEDs do not produce much heat, so there are no requirements of additional circuit for cooling. Only with these grow lights, you can easily touch them with your hands without burning.
Perfect Power Saver
Because LED grows lights are cool, their power consumption is much less than other grow lights. Less power means less money, which means profit.
Unlike fluorescent grow lights, LEDs do not contain mercury, and being energy efficient. Which is ideal for use in remote locations having both, wind or solar power stations.
LEDs come in various structures and designs to easily fit themselves. You can opt for either rectangular panels or circular depending on your needs.
Set Up Your LED Grow Lights
What do you need to set up LED Grow Lights for your plants? You only need a usable hand and a thinkable brain, because set up it is stupid easy!
You don’t need a hood because it has one. Also don’t need ballast, exhaust,… because all of them was set completely in a kit. But there are some things you must know before choose and set up your grow lights:
Back to top of this page, you will see many kinds of LED Grow Lights with many parameters, but you should focus on two important parameters:
Each type of LED has a different power consumption, base on your budget and garden area, you can choose the best for you.
For the first times growing indoor, you cannot estimate the brightness by eyes, you will need a Led PCE-LED 1 to measure how much lighting is enough for your plants. Holding Led PCE-LEDat the top of your plant and drag up or down your grow light base on the number appear on the screen.
30k – 60k Lux is suitable to the growth of many crops; flowering need more light level, about 45k – 75k Lux. Normally, with 400w lamps, the ideal distance from the lamp to the top of the plant is about 60 -70 cm.
The color of LEDs:
There are many colors, but you should focus on two colors: RED and BLUE. Red light is essential for plants to grow and bloom, using the red LED Grow Lights when you want to grow flowers or fruit trees. Blue light harmonic the progression of plants, blue LED Grow Lights suitable for leafy crops such as vegetable.
But too much red light can make your plants become taller and slender so it will easy to break. So I recommended you should mix blue and red Led, the rate between them depends on the purpose of cultivation as described.
Disadvantages Of LED?
Does LED have disadvantages?
The answer is probably not easy to find from the “default” advantages of the characteristics of the LEDs compared to conventional lamps. If anything, many people will think that the disadvantages of LEDs are more expensive than the conventional ones.
In fact, the price of LED lights is high, but when taking into account the long-term benefits, the benefit of power saving, benefit from not having to replace the bulb regularly, so the cost of LEDs is also cheaper.
So, does LEDs have any other disadvantages?
The answer will make many people think about it, and certainly, those who have used LEDs also agree: Disadvantages of LED is that the quality of the LED lamps on the market is too far apart.
This main drawback makes many customers were confused about the quality of LED lights. Users easily to buy substandard products with a poor quality CHIP LED, leading to the decline of LEDs brightness and the lamps emit light unlike the original after a short period of using time (about 2 months).
With a smart user, he will replace it with a good quality LED, but if the user doesn’t know clearly about the cause, he will replace it with a conventional lamp and never use LED lights again.
According to some studies about LEDs, LED lights to save about 90% power consumption compared to incandescent and 50% compared to compact fluorescent light bulbs. LEDs can achieve this efficiency because the power factor of LEDs is approximately 0.97 while the traditionally lights achieving only 0.1 – 0.5.
In addition, the unique cooling system of LED products also helps reduce air conditioning power. This means consumers save up to 2 times when using the LED to replace the traditional lamps.
LED lights with 3200K and 6500K color temperature, so it’s perfectly suited to use LED lights for every space not only for family space. Moreover, LEDs do not flicker when emits light so that they don’t cause damage to the eyes.
The LED products also have anti-glare measures to protect the eyes. And one important thing, the LEDs do not contain toxic substances (mercury, lead, Cadmium…) and LED radiation is safe for users, especially for children.
Energy efficiency of the LED is very high compared to fluorescent, up to 70% (70% of the energy is converted to light). In addition, the flux decline of compact fluorescent light very quickly, while the LED lifetime of 50.000 hours meets the L70 standard, IE after 50.000 hours of usage, the residual flux of the LED is 70% compared to the new LED. Through a few simple numbers of LEDs, we think that consumers can choose the best products for their family and should not be ignored LEDs.
In addition, the replacement of LED is extremely simple to LED tail E27, E40 standard, it can be directly replaced. For tubular LED, there are many replacements LED products depending on the requirements of the LEDs users.
The fact that the cost of LEDs is still high, but users should consider two factors before attention to the product price of LEDs:
- Long-term benefits that LEDs provides: LED life reaches up to 50,000 hours, the equivalent of 12 years (if use the LEDs 12 hours/day). And also, LEDs save the cost of maintenance for the LEDs during the usage time.
- Health benefits that LEDs provides: LEDs do not contain toxic chemicals and harmful radiation, so they are very safe for consumers, especially for children.
In addition to the above advantages, LEDs also bring some economic efficiency and even social performance prominent than other lights.
Some other socially efficient than LED lights to bring:
- LED lights to generate less heat than other lighting devices because they are not using the filament to heat and emit the light, LEDs have a lower working temperature compared to fluorescent lamps, about 13 C degrees to 250 C degrees, but produces more light than other lamps.
- Using LED lights to help to reduce 80% of CO2 emissions, due to the advantages that LEDs have, they will both benefit the health of consumers and environment-friendly
In summary, the disadvantages of LEDs are a minority compared to the benefits that LEDs offer such as environmentally friendly, safe to use, saves electric power, no need maintenance, long lifespan… LED current prices are high, but considering the long-term effects of the use of LEDs is still cheaper than other types of lights.
