Dual Band vs Tri-Band

So what’s the difference between dual band vs tri-band grow lights?

That is a very common question people ask.  The difference between dual-band, tri-band, and five band grow lights.

To help you make your understand the difference you need to first understand the light spectrums for photosynthesis.  The 2 primary light spectrums absorbed by plants are the red and blue lights. Unlike the human eye, which most efficiently absorbs green, yellow and orange, plants most efficiently use narrow wavelengths from the red and blue spectrum, which is why the dual-band led grow lights we sell are the best selling ones.  Our dual band LED grow lights provide the plants with the optimal 8:1 ratio of red to blue lights to match the photosynthetic curves of Chlorophyll A and B, the two primary compounds that drive photosynthesis. This is why our LED grow lights do not include wasted colors such as yellow or orange. This ensures the highest conversion rate of electrical to plant energy, with little to no wasted energy.

Tri-band led grow lights provide an additional color for the plant to appear fuller and greener.  It provides the lights of 7:1:1 ratio, so keep it mind these models do provide 10watt less in red light, which will affect the speed and size of the plant growth.  Both the dual-band and tri-band enhance photosynthesis and saves energy by not generating light in colors that plants do not use.

To summarize, the main difference is the 10 watt powered by 6,000 Kelvin Warm White LED in the Tri-Band model (70W of red spectrum in the Tri-Band vs 80w of red spectrum in the Dual Band model).  Both models are built with the optimal specifications for plant photosynthesis.  95% of the light from these LEDs can be absorbed by plants, compared to only 10% by HPS or MHS. Other models offer poor wavelength settings that are not the exact 660nm Red and 460nm Blue peaks absorbable by plants.
