what led grow light should i buy?

Published by Cretivity 2021-08-02

As the planting system changes, planting patterns can also be diversified, from land planting to soilless planting, from outdoor planting to indoor planting, but no matter what kind of planting mode, plants cannot do without light. This also brings a lot of difficulties for the growers.


How should I choose plant growth lights? What kind of grow light is needed? What kind of grow lights can I buy?


This article will help you solve the problem-what kind of growth lamp that should be purchased.

Whether you are a novice or an experienced person who knows very well about grow lights. First of all, we must understand clearly what is a grow lights.



The growth light is a kind of lamp that provides light compensation for greenhouse plants in accordance with the natural law of plant growth and the principle of photosynthesis, which can promote growth, prolong flowering, and improve quality. It is usually also called plant supplement light or greenhouse supplement light. For indoor planting, because there is little light, the growing light can provide enough light.


There are many growth lights on the market, the most widely used are fluorescent plant lights, HID (High-Intensity Discharge) growth lights, LED (Light Emitting Diode) plant growth lights. It is very important to understand the type of growth lights, which is very important for you. How to choose to grow lights is very helpful.


The conditions that the growth light must have


1. Plants that suit you

For many people, it is a big question whether buying plant growth lights will help their plants grow. All plants need photosynthesis, but different plants need different light, just like the difference in light intensity required by medicinal plants, vegetables, and succulents. However, due to the development of the form of plant lighting, the current LED plant growth lights on the market are suitable for all planting plants.

CRETIVITY CT series LED growth light is a new type of plant growth light with high molar value and full-spectrum, which can be customized with different LED spectrums according to users.


2. Application environment

Nowadays, with the diversification of planting modes, the use environment of growing lights has also increased. Hydroponic planting, vertical planting, greenhouse planting, small indoor growth space, etc., the application environment of multiple growing lights is another challenge. It needs to adapt to many environments such as damp, dry, dusty, corrosive, etc. So a good growth light can make you use it longer. At present, as the mainstream growth lamp occupying the market in the future, LED growth light is popular because of its wide application environment, one of its many advantages.

CRETIVITY CT series LED growth light is a wide range of application environment LED growth light. It has a unique structure design, convenient and quick installation, IP45 protection level and IP67 driver waterproof level, strong waterproof and dustproof, anti-corrosion coating And profiles, the light bar adopts aviation-grade aluminum profile, which has good durability.


3. Spectrum

In the past, the growth lights were mostly white, blue, and red alone, but this did not produce good plants. At present, the necessary light for planting must be the same as sunlight to be more suitable for plant growth. The full-spectrum LED grow light is currently the best choice, with the white light and UV, IR, the blue and red light that the sun has. This has a vital impact on the growth of non-plants. Different light can promote the growth and development of different parts of the plant. Substances produced under red light make plants grow taller, while substances produced under blue light promote the accumulation of protein and non-carbohydrates and increase plant weight.



Greenlight and red and blue light can harmoniously regulate and adapt to the growth and development of plants. Although the far-red light at 730nm is of little significance to photosynthesis, its intensity and its ratio to the red light at 660nm have effects on crop height, internode length, etc. Importantly, ultraviolet radiation reduces plant leaf area, inhibits hypocotyl elongation, reduces photosynthesis and productivity, makes plants vulnerable to pathogens, but can induce flavonoid synthesis and defense mechanisms.

CRETIVITY LED growth light is a full-spectrum LED plant growth light, with 3000K warm white light and 6500K cold white light, 660nm red light, and combined UV and IR light. It is very suitable for planting medicinal plants and vegetables and flowers.




4. Cost

Different grow lights are different for users to consume and purchase. For commercial growers, the lower the cost, the more profitable it will be.

Only need to consider the service life of the growth lamp (the longer the life, the fewer the number of lamp replacements) and the power consumption (electricity), heat dissipation (whether a fan is needed for heat dissipation because this is another cost).

The durability of the LED grows light is very good. Its service life is more than 50,000 hours, which is 3-4 times that of the ordinary grow light.

The energy consumption of the LED light is also very low. A 640w LED grow light can produce The light intensity of the high-pressure sodium light exceeds 1000w, and the LED plant growth lamp has the characteristics of low heat dissipation.

It can dissipate heat by itself without relying on peripheral equipment to dissipate heat. The ordinary growth lamp emits high heat when it emits light, which also has a direct impact on Plant growth and high heat dissipation will affect the life of the bulb.


5.Understand the surface area

If you plan to grow plants at home, then you may not need a lot of LED to grow lights. However, in the case of a large greenhouse, you need to have multiple units. You need to know the surface area to calculate how much light should be provided.

If the surface area is large, consider buying multiple lamps so that each plant can get enough light. Those directly under the lamp will not have photosynthesis problems because they have enough light. However, those plants far away from a single light may be difficult to grow healthily.


6. Consider PAR

Photosynthetically active radiation or PAR is light that is beneficial to plants. It is a substitute for sunlight used by plants, so they can photosynthesize. LED grow lights can have different PAR values, depending on the manufacturer. Having said that, a higher PAR value does not necessarily mean a better light bulb.

PAR should be evenly distributed among the plants, which is why you need to know the surface area of ​​the garden because those plants directly under the light will receive more PAR, while those farther away will not. The best LED grow lights that you should consider are those that can evenly distribute PAR.


7. Look for lights that provide programmability

Choosing which kind of LED grow light is difficult because many different brands produce a wide range of variants. Each product will have various functions, which may or may not be beneficial to different users.

You may find that the best types are those that provide programmability. 

Programmable LED grows lights are very efficient because you can adjust them to your needs. 

You can set a schedule for when the lights are turned on and off, so you don't have to do this manually. 

Some even allow you to adjust the intensity and spectrum of the light to suit the types of plants you are growing.

Therefore, through the above options, you can make a wise choice according to your budget and needs, but under the current planting mode, in the future plant lighting fixtures, LED plant growth lights will replace all lighting equipment, LED plant growth lights It is almost certainly the future of the horticulture industry. 

Even today, the advantages outweigh the disadvantages, and higher costs are the only serious disadvantage. As prices fall, this shortcoming is quickly disappearing. Good LED plant lights work well, and they can easily surpass any other type of garden lighting on the market today.
