Choosing the Best LED Grow Lights
What is the definition of ray?
Ray means each of the lines in which light and heat seem to stream from the sun or a body which is luminous or pass through an opening which is often small.
What is the definition of direct rays?
A direct ray is when the Sun's light hits the specified part of Earth that you are observing at an exact angle of 900. This means that the Sun's rays are perpendicular to the Earth; Direct rays compared to indirect rays are one of the factors for the occurrence of seasons on Earth.
The sun's rays the most direct
At the equator at the equinoxes, and at some point between the two tropic latitudes (Cancer or Capricorn) the rest of the year.
The sun's rays are least direct
Anywhere on Earth around the time of sunrise and sunset and the Earth's polar regions, throughout the year in general.
With this in mind
Choosing an LED Grow light has many factors that you will want to take into consideration.
- The Visible Light Spectrum Color Wavelength (nm)
- Red 625 - 740
- Orange 590 - 625
- Yellow 565 - 590
- Green 520 - 565
- Cyan 500 - 520
- Blue 435 - 500
- Violet 380 - 435
Plants use and absorb an array of colors from 400nm to 700nm in order to carry out photosynthesis and other developmental processes. Many LED Lights only use 2-3 of the primary colors needed for photosynthesis and plant growth. LED Grow Lights that features a complete 12-band spectrum that provides your plants every lighting component needed for robust and complete growth, throughout all stages of their life cycle.
Now another important consideration in choosing an LED grow light is the power of the diode chip set. Single watt LEDs are weak and don't have enough intensity to penetrate the canopy, where as the other end of the range, new 10-watt chip sets are unstable, and heat generated from a large diode can be difficult to manage. For this reason, a three-watt diode is considered the practical one to use.
Here is a LED Grow light details to help chose the LED light you want.
