Practical advice on commercial lighting from LED retrofits to lighting design.

Are you currently retrofitting to LEDs and left with some old lamps? Do you just pile them up in the back of your building?

Hopefully not.

As we move forward in the ever-changing world of lighting, staying educated and sensitive to the environmental impact of energy consumption and use of lighting has been more important than ever before. When you purchase lighting, you may not just be thinking about replacing the lamp that is in the socket, but also thinking about how the new product will impact energy, as well as the environment.

When reading a lighting label or cut sheet for a lighting product, lumen count may seem to be the main metric for measuring the potential of a lighting product to produce brightness. But this metric doesn't tell you everything. A high volume of lumens does not automatically equal brightness in your space. There are several other factors that will impact the end result.

Let's back up before we go too much further and briefly define lumens.
