Can any LED light be used as a grow light？

First of all, we can introduce the grow light for you.

A grow light or plant light is an artificial light source, generally an electric light, designed to stimulate plant growth by emitting an electromagnetic spectrum appropriate for photosynthesis. Grow lights are used in applications where there is either no naturally occurring light, or where supplemental light is required. For example, in the winter months when the available hours of daylight may be insufficient for the desired plant growth, lights are used to extend the time the plants receive light. If plants do not receive enough light, they will grow long and spindly.

Grow lights either attempt to provide a light spectrum similar to that of the sun, or to provide a spectrum that is more tailored to the needs of the plants being cultivated. Outdoor conditions are mimicked with varying color, temperatures and spectral outputs from the grow light, as well as varying the lumen output (intensity) of the lamps. Depending on the type of plant being cultivated, the stage of cultivation (e.g. the germination/vegetative phase or the flowering/fruiting phase), and the photoperiod required by the plants, specific ranges of spectrum, luminous efficacy and color temperature are desirable for use with specific plants and time periods.

–From WIKIPEDIA

As plants need spectrum, while the LED light (LED plant grow light) just design for it. As we all know, the red and blue spectrum play the most important role on plants growing. And other spectrums like yellow, white, IR and UV also can make the plants grow faster and better.

There is an almost endless list of benefits to using LED plant grow light.

Space Saving Design

Where other types of grow lights require a lot of space and will often require a lot of equipment to run, LED grow lights free up your space. The relatively small grow lamps will make it possible to move more freely throughout the grow room, since you will not have to worry about extra equipment and cooling systems that usually take up so much of the available room. The more freely you can access your plants, the better care you will be able to provide. The LED grow lights can be used in greenhouse, vertical farm, hydroponics and horticulture. Same space, while you can grow more fruits and vegetables.

Low Running Temperature

The temperature of your grow room is incredibly important. Without the right attention paid to how hot your grow room is getting, you will run the risk of losing entire crops. Even with the right attention, it can often require extensive cooling systems to keep your room cool. LED grow lights have an advantage in that they run at a temperature that is simply warm to the touch, rather than approaching 400 or even 500 degrees.

Power Efficient, Save Money for You

Traditional forms of lighting your indoor grow can be very powerful, but unfortunately they aren’t very power efficient. That is why LED grow lights are preferred. They have the power to produce a great deal of light without having to draw much power. it can save more energy for you, means you can save much more money.

Long Lifespan

When you use the best LED grow lights, you will have the chance to grow for years without having to replace your lighting system. Most LED lights are rated at somewhere between 50,000 and 100,000 hours of use. For comparison, many other grow lights tend to last for around 20,000 hours before needing to be replaced.

In summary, LED lights be used as a grow light. And you can get much benefits when you start using them.
