This recent article by Electrical Construction & Maintenance (EC&M) Magazine argues that the concept of quality in design and manufacture has returned to the lighting industry with the introduction of LED lighting systems after the trailing years of incandescent/fluorescent lighting where the only thing that mattered was how long the bulb lasted.

The quality of materials is a key differentiator in LED light manufacture as LED installations “often represent a substantial long-term investment in improved, value-added illumination and savings in energy…”

However, the quality of materials in use across the industry varies, and subpar bulb performance is still a problem.

Light Quality: Back in Style

After its meaning eroded in yesteryear’s lighting, quality of design and build is becoming an essential part of the LED bulb-selection equation, expanding the distance between competing suppliers in the process.
