If you are new to indoor growing or looking for a led grow light guide to help you choose the best LED grow light, there are several things to consider. When choosing LED grow lights, this buying guide might help you make a better decision.


Many horticultural growers in the modern world could benefit from using LED plant lights if they knew which grow lights would be best for them. However, not many of them know how to pick the best. For a full, comprehensive guide see our below Guide.


First, a simple definition: The acronym LED simply refers to Light Emitting Diode, which is a relatively small bulb of light. To produce adequate amount of light required for a given purpose, the diodes are used in great numbers, and in different colors. The latest generation lights use the more efficient COB (Chip on Board) LED technology. Horticulturalistsgenerally use LED lights for both personal and professional purposes.


The LED bulbs and LED COB modules used in the LED industry have long lives and are very efficient. Available in different colors, they provide an efficient and convenient alternative to natural light for indoor plants.


The lights are necessary to accelerate plant growth and aid in the photosynthesis process. As more people adopt the practice of indoor growth of plants, the use of light emitting diodes also continues to grow. With demand, technology evolves, improving the advantages already apparent in LED lights. Such advantages include the ability of the user to control the provision of light required by the plants. For that reason, it is advisable to choose the best LED grow light that you can find based on the type of plants you grow.


Many growers still do not know a proper method to apply when selecting the LED grow lights. Growers choose LED fixtures because they conserve energy and maximize yields. Here are 5 points to observe when evaluating LED lighting fixture.


1.Choose LED fixtures with adjustable output spectrum.

Given that the LED arrays these days often come with different color LEDs which means the wavelength having a specific effect for plants growth, you need a solution that allows you to manage the light output spectrum according to the plants you grow or seasons. For instance, you can match the colors to flowering season, or to summer time. By varying the light output, you can simulate the seasonal light changes to suit the growing circle of the plant.


2.Select a good heat dissipation performance LED fixtures with high power cooling system.

High power LED grow fixtures need cooling, just like computer CPUs. For that reason, you need a heat sink and a fan. Since the LED fixtures do not radiate any heat, they have a metal pad that provides the way for heat to leave the LED.


3.Look for fixtures that are mounted on a metal core printed circuit board (or MCPCB for short), which is a space-grade technology for electronics that operate at high temperature

The device is better than the normal device circuit board and you will need it for the high levels of power that your LEDs use.


4.Make sure your circuit board is mounted to a sizable heat sink, preferably one with several fins

With more fins, the circuit board is able to spread heat out faster to aid faster cooling. This is important to prevent failures caused by single fins, leading to overheating and  damage to the LED fixture.


5.Consider LED fixtures with constant current driver circuit design .

When buying LED fixtures consider the electronic current circuit that powers your LED lights. The role of the electronic current circuit, or driver circuit as it is professionally known, is to convert AC power to direct current within the proper voltage and current level that the LED fixture can sustain. A proper LED circuit driver should supply a constant supply of direct current and regulate the intensity according to temperature changes.


6.Using the isolated power supply design . 

  • Isolated power supply with high conversion efficiency

  • Isolated power supply is small in size and takes up little space, saving international transportation costs。

  • Low cost 

  • Circuit design is relatively simple。

  • Strong anti-interference ability

  • Easy to achieve lifting pressure conversion

  • Easy to achieve multiple outputs

  • High security

  • After an abnormal power supply, the damage to the load is relatively small

  • Easy to implement wide voltage input range
