Three common misunderstandings when purchasing LED plant lights

When you purchasing LED plant lights, you would heard that LED plant growth lights are energy-saving, environmentally friendly, long life span, high efficiency etc. This is an indisputable fact, however some performance was exaggerated, the three common misunderstandings when purchasing LED plant lights are as below:

(1) The life span of LED plant growing lights is equal to the working time of LED plant growing lights

At present, most LED lighting fixture manufacturers can achieve the life span of LED plant lights for more than 50,000 hours. This life is the theory life that the lamps can be used. There is no indication of the factors of light decay and technical replacement.
The light decay of LED plant growth lamps includes many aspects. On the one hand, the lamp chip itself, any illuminating lamp brightness will decrease after working for a long time.
On the other hand, accessories, including wires, cob panels, lenses, cover etc., will age after a long time, even if it is replaced with new LED chips, it is impossible to achieve the best plant lighting effect as before.
Talking about the technical replacement of lamps, who knows what will happen after ten years? Every year, new products will be launched, and the performance will definitely be better than before. At this time, should you buy new ones or not? Perhaps one day LED plant lights will be replaced by the next generation of other emerging light sources. Should you buy new ones or not then?

(2) The higher the power, the greater the brightness, the better the effect

Power refers to the power consumption of LED plant growth light in a given time, and it has no direct relationship with LED plant growth light supplement effect. If a regular LED plant growth lamp produced by a manufacturer is irradiated with a small pot of aloe vera, the same luminous area and illumination angle, 24w LED plant lights hanging at 50cm height can meet their growth needs, why you need a 100W LED plant growth lamp placed at 100cm height? The key factor we should pay attention to is workmanship, quality and effectiveness.
Brightness is the definition of light perception by human eyes. The perception of light by plants is calculated according to illumination lux, it is not the brighter that the human eye feels, the better effect of plant LED light will be. We’d better choose different LED chip ratios according to different stages of plant growth, to achieve the optimal growth during plants’ different stage.

(3) LED plant growth lamp is a cold light source that will not burn plants

LED plant lights are cold light sources, which are relative to other plant growth lights. All products related to electricity will generate heat. At present, there is no photoelectric conversion source that can achieve 100% photoelectric conversion, more or less a part of electricity will be converted into heat, it is same for LED plant lights too.
A low power LED plant growth lamp can illuminate the plant at a very close distance, especially for the stage of germination. However, if the LED plant growing lamp is attached to the plant, the heat of the LED plant growth lamp radiated to the plant for a long time will also burn the plant, needless to say the high power LED plant lights, just look at the cooling fan behind the high power LED plant lights, you will understand.

Therefore, the first thing we need to do when purchasing LED plant growth lamps is from the perspective of plant growth needs, and determine a plant lamp that is really suitable for the growth of your own plants. When using the lamp, pay attention to the illumination distance, the interval between the lamps, and the lamp working hours etc.

Full spectrum LED plant growing light function and advantages

What is a full spectrum LED plant growing light ?

The full spectrum LED plant growing lamp is a complementary light source for plant growth developed by simulating the solar spectrum. The visible light in the spectrum with reasonable portion from the 385NM blue light to the 780NM red light, and the light curve simulates the shape of the solar spectrum. The color temperature similar with daylight color at 10:00 in the morning, with strong color rendering ability and small color temperature drift, high light efficiency, high luminious flux, can fully meet the requirements of greenhouse plant lighting.

Full spectrum LED plant growing light function

The full spectrum LED plant growth lamp was artificial light source with full spectrum developed based on the principle of plant growth and simulating the ratio of solar spectrum, with wide radiation range and brightness of more than 100 lumen per watt, which truly meets the requirements of green and energy-save lighting.
It can used as a supplemental light for agricultural greenhouses, light can be enhanced at any time of the day to help plants with photosynthesis. Especially in the winter months, you can extend the effective lighting time. Whether at dusk or at night, the illumination required by plants can be effectively extended and scientifically controlled without affected by any environmental changes.

Full spectrum LED plant growth light advantages

The full spectrum LED plant growth light was developed according to the wavelength range of sunlight required for plant growth and the required illumination. The rational usage of this light can not only help breeding and growing under conditions that are not suitable for plant growth, but also accelerate crops breeding and shortening the growth cycle of crops, eliminating the occurrence of pests and diseases.

How to choose good LED plant growing lamp manufacturer in China?

Relatively speaking, the LED plant growing lamp industry is still a blue ocean industry, but with the rapid development of the LED plant growing lamp industry in recent years, there are more and more LED plant manufacturers appeared.
Due to the high technical requirements, most LED plant lamp manufacturers can be regarded as regular manufacturers, but there are still some bad companies in this industry, please be careful when purchasing LED plant lights, otherwise you can not get what you have paid for.
Regarding the choice of LED plant lamp manufacturers, here are a few suggestions:
(1) Look at the operating years of LED plant lights manufacturers, you can ask the supplier to provide you the business license copy, they should operating for at least three years; or you can ask your ship agent or friend in China to call them, and you can judge depends on their communication feeback.
(2) See if the manufacturers has their own workshops, many LED plant lamp traders are playing the game of factory direct sales, actually they even don’t know what are their products like. Actually regular manufacturers usually have their own official website, the corresponding sales channel on B2B platform such as alibaba.com, made-in-china.com, globalsources.com; then just ask customer service some question related to the products, regular manufacturers are generally given more professional answer.
(3) See if the LED plant lamp manufacturer has at least one relevant certification (such as CCC certification, CE certification, FCC certification, ROHS certification, SAA certification, UL certification, ETL certification etc) to ensure product quality is qualified;
(4) You should know some related knowledge about LED plant growing lamp, such as LED chip, structure, power supply, lens, reflector, cob, SMD … so as to make better judgments when encountering problems;
(5) Defining the specified demand for LED plant lights, and requesting LED plant lamp manufacturers to customize related products according to your requirements.
Based on the above five points to analyze a LED plant growing lamp manufacturer, if they can pass it, then at least it can be proved that this is a regular LED plant lamp manufacturer, and the rest is the connection between the LED plant lamp manufacturer’s products and your needs!

Main components inside a complete LED plant growing light

LED plant growing lamp as a special light source for plant lighting, although its production process has been relatively mature, but its price is still high, there are home usage LED plant lights cost below 30$, the price is not too high; there are also a few high power commercial LED plant lights which cost several hundred dollars, what are the hidden parts inside the lamp? Let’s take a look at what components are included in a complete LED plant growing light in this article.

(1) LED plant light lighting source (LED chip)
It is the most core components of LED plant growing lamp which emit spectrum for plants. The quality of LED chip also determines the quality of LED plant growth lamps. At present, LED plant lamp chips used in China are mainly imported from abroad.

(2) LED plant light power supply (adapter)
LED plant light chip needs low-voltage direct current to emit light, and whether it is commercial electricity or household electricity, it is AC. The plant growth lamp power supply is a device which reduces the high voltage and converts AC power into DC power, then the DC power will be assigned to each LED chip.

(3) LED plant light cooling device (fan, heat sink etc)
The luminous efficiency of LED plant lamp chip is related to temperature. It decreases with the increase of temperature in the normal temperature range, and temperature also has an effect on the light decay and life span of the lamp. The function of the cooling device is to ensure the efficient and long-lasting operation of the LED plant growing lamp.

(4) LED plant light cover (glass cover, acrylic cover etc)
The main function of the LED plant light cover is dustproof and protecting the light. The glass cover and the acrylic cover are common covers used for LED plant light in the market. The glass cover has good light transmission, is not easy to be deformed, is heavy and fragile, and the acrylic cover is light in weight, non-fragile, variability and unfavorable to environmental protection.

(5) LED plant light lens / reflector cup
The role of the lens and the reflector cup is to use the physics theory of light to change the trajectory of the light to achieve the concentrating effect, and to ensure the efficient usage of light emitted by the LED plant lamp. The lens changes its propagation trajectory by the refraction of light, and the reflector changes the trajectory of the light by the reflection of the light.

(6) LED plant light housing (plastic housing, metal housing etc)
The main function of the plant growth light housing is to protect the LED plant lamp from damage during transportation, installation and usage, or protect the operation staff from electric shock, and also increase the additional value of the lamp, there are mainly metal (stainless steel, aluminum, aluminum alloy etc) housing and plastic housing in the market, in which the metal housing is used at a high rate.

(7) LED plant light internal plastic link device
Covering bare wires, mainly for insulation purpose, preventing electricity leakage from affecting the safety of users, and secondly, fixing the components inside the lamps.

(8) LED plant light aluminum pcb board
The LED plant lamp chip is directly connected to the aluminum pcb board, and the main purpose of the aluminum PCB board is fix the LED chips and dissipates heat.

(9) LED plant light smart control device
Some LED plant growth lights need intelligent control. For example, they are used in LED plant light tents, LED plant lamp factories where need timer, or simulate the phenomenon of natural sunrise and sunset light. It is necessary to add smart control devices inside the lamps to achieve remote control.
