❮ Edge-X Lighting ​Technology Overview
​Asymmetrical
Comparing Q-Wall to conventional asymmetric systems.
Here's an example of how well Q-Wall can wall wash compared to conventional asymmetric systems. The luminaire on the far right is powered with a Q-Wall optical engine and conventional asymmetric systems of both fluorescent or LED are on the left. The preferred solution is Q-Wall with it's wall uniform and reach in vertical illumination reach.
​By simply substituting LEDs into conventional optical arrangements, no appreciable improvement has been made from past lighting technologies. In fact, as is seen in LED Fixture D, sometimes the results can be worse due to how much brighter LEDs are now compared to older light sources.

QuarkStar Q-Stax
With just a single row of lighter fixtures outfitted with our Q-Stax optical engine, uniform illumination from top to bottom of shelving is achievable. Q-Stax also features walkway illumination matching the shelving for consistent experience.

​Conventional Stack Lighting​
Conventional stack lighting commonly producing unwanted hot spots are near the top and low lighting conditions near the bottom shelving.
