First, the working principle of LED As the name implies, a light-emitting diode (LED) is a semiconductor device that emits light of a specific wavelength (color). Like other semiconductor chips, the semiconductor chip of the LED (the actual light-emitting unit of the LED) is also packaged in plastic or ceramic. Of course, there can be one in a package or multiple chips. When the LED is in forward conduction (open), the electrons recombine with the holes while releasing energy in the form of photons (as shown in Figure 1.1.1). This effect is often referred to as electroluminescence. Figure 1 When the LED is excited, the electrons and holes recombine, and at the same time, the energy is released in the form of photons of a specific wavelength (color). LED technology , a commonly used term in lighting applications, is called solid state lighting (SSL). This is because the principle of illumination is distinguished from incandescent lamps (luminescence is achieved by thermal radiation in the visible spectrum), and the technique referred to by solid-state illumination is achieved by solid state electroluminescence. How white LEDs work The most common method is to use a single color LED (mostly a blue LED with indium gallium arsenide process) to achieve white light with different colors of phosphors. The corresponding LED is called a fluorescent white LED. High brightness LED (HB LED) is excited. Part of the blue light is converted to yellow light by the fluorescent layer, and the other part passes directly through the fluorescent layer in a blue light manner. Eventually, the mixture of blue and yellow light forms white light.

Phlizon COB series Grow Light emits all the wavelengths of light which can be fully absorbed by the plants to create.
Best full Spectrum designed to perfectly match large areas of indoor plants, especially for Medical Plant.
COB + Dual-chip,most efficient spectrum,high PPFD.Two cooling fans with double ball(import from Japan) and big aluminum heat sink to protect the grow lights from high temperature,good cooling,long lifespan.Photosynthesis and promote healthy growth budding and flowering.
1000w/2000w /3000w COB LED Grow Light, it will give you more options when your plants need different strength of illumination.
Grow Lights are a great choice for growers who are dealing with hot HPS lights and want to change to something that's going to run cooler. Although Led Grow Lights do produce heat,the smaller models might not bring up the temperature of your grow space.Even the more powerful models of LED Grow Lights that produce a lot of heat still have built-in cooling systems to help prevent the heat from beaming directly down onto your plants.

WHAT MAKE UP AN EXCELLENT LED GROW LIGHT ?
1.PPFD Value : PPFD is Photosynthetic Photon Flux Density. When you choose a plant light, you should compare the PPFD values of different plant lights. The larger the value, the better the growth of the plant.
2.Actual Power: Because the actual power of the plant light always varies with different conditions, all Amazon sellers use the rated power to describe the power of the product because the rated power is constant. When you pick a LED grow light, the rated power of the plant light is a reference, and more importantly is the actual power.
3.Core Coverage: In addition to the above two, when you choose a plant light, you also need to compare the cover area of different plant lights, of course, the size of the core coverage area. In general, in germination stage, you can hang the plant light higher and the cover area is larger. In flowering stage you can hang the plant light lower and the cover area is smaller because the plant needs more light at this stage. You have to compare different coverage areas to choose the plant light that suits you.
