What is Gardening Grow LED Lights?
The name itself symbolizes that these are artificial lights which are especially designed for uninterrupted growth and nurturing of the plants in the absence or scarcity of sunlight.
These lights either produce full spectrum light as in sunlight,or produce a particular range of light,suited to their market-for starting seeds, indoor plants and greenhouses, flowering and vegetative plants, or for all phases of plant's life.
Why this light so important to your plants?
Plants need sunlight to carry out a process known as photosynthesis-the process of conversion of carbon-dioxide into compounds, by utilizing the energy for sunlight. In the absence or in the scarcity of light, plants can't synthesize their food, and can't flourish as desired.
Let us now quickly understand about the colors which make up the sunlight. The sunlight is made up various colors which have its own wavelength. For example, the wavelength of blue light lies in the range of 490-450 nm while the red-orange range has the wavelength of 700-570 nm.

Advantages for led Grow Light
1. Bring You High Yield
The traditional grow lights, such as HID and HPS can just bring you 0.5 -0.8 gram per watt, no more than 1 gram. But the led grow light can bring you 1-2.5 gram per watt. It's amazing! LEDs in greenhouses deliver same yield as grow lights, using just 25% of the energy. So as for the energy conservation and environmental protection light source, the planters will consider the led grow light as their first choice.
2. Less Heat
While most grow lights are very warm, as HID, so you would need use the fan to solve this problem in summer. LED grow lights are generally moderate in temperature, and they will not harm a person if he touches them. As such, it is much safer and convenient for owners and their crops, they can be placed very close to the plants to deliver high intensity lights to the surface of the leaves.
3. Low Cost On Everything
Less electricity, save about 60% than HID.
Low amounts of heat, means less money spent on the room's costs of cooling.
Long life-span, no need to replace the bulbs.
No ballast.
No reflector.
