Light Emitted for Plant Growth
Do the LED grow lights look dim to you?  It's all in your perception.  Much of the light emitted from
your LED Grow Master lighting is nearly invisible to the human eye.
Human Vision     
Humans see colors in the yellow-green spectrum (white
light) many times better than in the blue and red
spectrum that plants prefer.   Nearly 60% of the light
emitted by your new grow light bars is nearly invisible to
the human eye.  You are only seeing the densest part of
the cone.  Most of the light you see is coming from the
small amount of green and blue in each cluster which
your eyes perceive as bright.

Figure 1, What you see...
Your new grow light bar emits a soft mix of colors,
without the harsh "white light" pollution typical with
most lights.

Figure 2, What your plants see...
Plants are bathed in artificial sunlight, without clouds,
rain, wind.  Did you know your new grow light bar
emits light which typically does not attract bugs to
your plants?
Plant Vision
Plants, can barely see (use) yellow-green light, which
is also perceived by the human eye as "white" light.   
Instead, plants prefer light which is rich in red and
blue light.  Your grow light bar is a perfect mix of red,
blue, and other colors that plants need for health,
taste, and smell.
