The Key Points To Choose LED Grow Light
Most of the lighting companies on the market claim that their LED Grow Lights with unique structure, spectral design or long warranty period, which can provide the best growth for plant growth. These suppliers will tell you: “We have the best high quality lights!”
But the problem is that any LED Grow Lights manufacturer can’t ensure that their products can get the best growth light in every environment. As we all know,different plants need different spectrum to grow.
First, What is LED Grow Light?
The LED Grow Light is a luminaire containing light-emitting diodes, which provides illumination for growing plants. These lamps are installed on the plant canopy of greenhouse or indoor farm. Commercial LED Grow Lights must be able to withstand harsh environments, usually used in controlled environmental agriculture.
Secondly, How to choose the best suitable commercial LED Grow Light?.
There are many factors need to consider when choosing a commercial LED grow light. First, you must decide what’s plant you want to grow. Before deciding on what to plant, Here still with few points you must think about to choose lights;
1-Effective ( With clear and good effect on plants); Here with 2 main factors: Good spectrum, suitable or higher PPFD uniformity. Generally speaking, the average PPFD for leaf vegetable planting needs 250umol / m2 / s, 150umol / m2 / s for tomato seedling planting, 400-600umol / m2 / s for vegetative growth, and 600-1200umol / m2 / s for flowering and blooming harvest.
For long-term health preservation and flowering period of tomatoes, additional carbon dioxide can be added. The growth stages of cucumber and pepper are basically the same as those of tomato. Adding carbon dioxide can also increase the yield.
Illumination uniformity: it can also be said that PPFD uniformity. The higher the uniformity,Will the better. The uniformity is related to the suspension height. The higher the suspension height, the uniformity of light will be improved, but the light loss will increase.
2- High efficacy and energy saving : The effect of grow light has quickly become one of the main indicators for buyers to evaluate products. The higher the PPE, the better the effect of reducing power consumption. However, this indicator also has its limitations. For example, PPE only considers photons in the par spectrum (excluding wavelengths such as far red light) , Some buyers will take PPE as the only reference index for choosing lights, but we do not recommend doing so. PPE does not include spectrum effects and can’t represent the quality of lights. In practical application, these two aspects are far more important than the power consumption represented by PPE.
Almost all suppliers claim to their light can be to 2.7umol/j, which requires our good analysis and identification. Generally, the reliability of large brand(like Samsung ,Seoul,Philip etc…) will be higher. If it’s not a brand, we need to know the brand of LED diodes (it’s better to have a specific model) and the number of diodes, which can also help identify the reliability of light effect. Generally speaking, under the same brand,the more diodes, the higher of the efficiency.
3- Heat output of Grow Lights :In general, we recommend not to worry about the difference in heat output between LED lamps. However, you should consider the advantages and disadvantages .
In cold weather conditions, some greenhouse owners feel that the heat emitted by HPS lamps is more beneficial. but the lamp is not a reliable heat source because the heat is difficult to control. HPS growth lanterns produce heat in all parts of the greenhouse and affect plant growth in an uncontrolled manner.
Controlling the heat can achieve better product quality. The commercial LED growth lamp is the best choice. But if you want to use the extra heat generated by lamps and lanterns in the cold climate without considering other negative effects, you may need to find more traditional plant growth lights.
4- Safety and reliability: in fact, safety should be put in the first place. Lamps should meet the safety regulations of all countries in the world. In addition to meeting the safety regulations, they also need to be reliable and reliable to ensure long-time operation. LED lamps will also generate heat. Temperature rise is also an important indicator. Too high temperature will seriously affect the service life of plant lamps. Heat dissipation capacity is also an important indicator of plant lamps.
5- Long life: as mentioned above, low temperature rise is a way to ensure long life. Good components, especially power supply, are easy to be damaged. Led Grow Light with brand power supply or Certified driver, such as Meanwell and UL certifited, should be selected as far as possible; There are also LED diodes. We should also choose to major international brands, such as OSRAM Samsung, Seoul and other brand etc.
6- Easy to instal : LED Grow Light is installed above the plant canopy and depends on the distance between your canopy and plant. It is necessary to ensure that the grow lamp can be easily installed and replaced.Usually, it’s smart to know the manufacturer’s installation process before buying. A good manufacturer must also have a well thought out system that is easy to install, replace and expand
7- Warranty & Cost
8- Intelligent control: Like Dasiy Chain system for larger commercial cultivation
