What is the commercial led grow lights
Commercial plant lamps are used exclusively to illuminate plants, providing the red and blue wavelengths of light that plants need for photosynthesis. The effective wavelength of photosynthesis is the wavelength of red and blue light, other colors of light plants do not absorb, so only to provide plant photosynthesis effective light can maximize the use of energy to meet plant growth needs. In the sunshine can not meet the indoor, greenhouse, plant factory use. It is also used when additional light is needed to stimulate plant growth and regulate the state and timing of flowering.

What lights do commercial growers use
There are fluorescent lamps, HID lamps and commercial grow lights available in the market. It is recommended to choose greenhouse grow lights for any purpose. This is mainly because, compared to traditional plant lamps, led plant lamp has the following advantages: high light efficiency (energy saving), broad-spectrum coverage (easy to get monochrome or full spectrum), light intensity spectrum adjustable, long life, less heat (can be short-range lighting, saving planting space), lamps and lanterns form diversity (can meet the needs of different application scenarios), the use of high security.
For example, in our growing experiment, it took 45 days for vegetables to mature in the natural environment, and it took 30 days to grow into a 45 day effect using LED fill lights.

Another example: At present, there are many HID lamps used in greenhouses, but HID lamps are not as efficient as powerful led grow light. Although HID lamps are much cheaper, power consumption is the biggest cost of supplementary lighting. According to the comparison of 600W LEDs and 1000 WHPS (HPS is a kind of HID lamp), the light quantum number of the two kinds of lamps is almost the same, but the electricity cost can save about 1400 dollars a year, and the life of a qualified LED lamp is 50000h, the high-pressure sodium lamp has a life span of only 3000h.

In addition, before purchasing the plant fill lamp, we need to understand some of the lamp parameters, including Lamp Power (related to filling light effect, energy consumption cost), spectrum (affect fill light effect), style, size, lamp material, weight and light source type (related to lamp life), etc.
Can you recommend some good brands/models of hydroponics led grow lightss?
At present, ECO FARM Lamps and lanterns products have the following advantages, you can choose the plant light of the first choice.

More professional spectrum, which means better variety quality, shorter planting cycle, higher yield, more active ingredient content, and more energy-saving;
High light efficiency
Efficient heat dissipation
Good Optical uniformity, no glare;
High optical efficiency;
Good protection.
