Q: What is the lumen output of your led grow light?

A: Lumens are a physical measure of the light seen by the HUMAN eye. Plants do not see the same light that humans see and therefore lumens are less relevant when it comes to plant lighting. Our LED Grow Lights produce light in the wavelengths that plants need most for photosynthesis and nutrient accumulation. Only a small percentage of the light produce by an HID light is absorbed by plants which means that 80% of the Lumens are wasted. It is the one of the difference between HID light and led grow light.

Q: How do LED grow lights work?

A: Basically, LED grow lights are unique in that they emitting light color that is within the spectrum that is correspondent to optimal plant absorption capabilities (red and blue). Since they are directional, they require no reflectors or ballasts like HID lighting. Additionally, all of the light that they emit is usable so they consume much less energy than the conventional artificial light such as HID, HPS etc.,.

Q: People say that LED growing lights save you money on your power bill. How much?

A: Studies show that the energy efficient LED grow lights typically provide 50%-90% saving over the HID lights when you factor in reduced cooling costs.
