Efficacy is the single most important spec of a grow light

Focusing on efficacy value without context is completely misleading. It's like paying attention to the 0-60 seconds of a sports car. While the car's ability to go from 0 to 60 in under 4 seconds is impressive, you might want to know if it can turn corners without crashing into walls or exploding before you buy.

White LED companies focus on efficiency values because white LED diodes generally have better efficiency than other diodes. Since white LED diodes are available and readily available in every conceivable industry, it makes sense that manufacturers would be willing to use them. After all, it's much simpler and cheaper to use off-the-shelf diodes than to make new ones with target spectra, which may be better for your factory. So white LED manufacturers use these off-the-shelf diodes and add some far-red diodes to make the lamps perform better during flowering.

As we reported last week, white light includes a lot of green and yellow light that plants can only make limited use of, most of which is reflected off their surfaces and converted into heat. This makes white leds very inefficient. But by focusing on the efficacy value of these white diodes, they have turned a cost-saving business decision into a marketing tool.

When judging a growth light, you cannot point to one characteristic as the most important. Several factors affect the viability of growing light, of which the spectrum and the intensity of the spectrum are the most important. Any company that leads you to a number in black and white is trying to divert your attention from the other defective parts of their panel. We have crafted a perfect mix of spectra to ensure that no energy is wasted in parts of the spectrum that plants will not use to grow and thrive.
