White Led grow lights provide a full spectrum of light designed to mimic natural light, providing plants a balanced spectrum of red, blue and green. White LED grow lights are designed to emit similar amounts of red and blue light with the added green light to appear white, with a high efficiency result.
It has been shown that many plants will grow normally if given both red and blue light. However, studies indicate that while red and blue light provides the most cost-efficient method of providing light for growth but plant growth is improved with lighting supplemented with green.
NASA has tested LED grow lights for their high efficiency in growing food in space for extraterrestrial colonization. Findings have shown that plants are affected by light in the red, green and blue portions of the visible light spectrum.
We find many LED lamps suppliers use arbitrary numbers that suggest their belief of what the power of the HID lamp being replaced might be. We use the true input or draw that each lamp uses so you can compare apples to apples. Determination of true PPF values is the best means of comparison.
What are some of the benefits of using LED Grow Lights?
See the Blog about PPF to understand the application to Grow Lights.
Charts describe the amount of light energy PAR/PPF at 12" and 24" off the the plant canopy for the 640 Watt lamp.
A IP67 rating means the unit can be dropped into a body of water up to a meter deep for half an hour, and is resistant to dust.
