Lighting is one of those things that modern, 21^st-century residents and professionals simply take for granted. Just flip a switch, and you're able to see and complete whatever task you have in front of you, regardless of whether there are no windows in the room, or if it's 10 o'clock at night. But lighting, despite being an older, fairly stable technology, continues to evolve and so have people's needs for new solutions. The type of lighting a child needs to do his or her homework at night is very different from the kind of lighting a staged play needs to ensure an audience can see the action. That's why lighting experts, with varying certifications, exist.

While lighting doesn't require a degree or a license the way medical or electrical expertise does, certain kinds of lighting needs will require someone with a recognized level of knowledge, experience, and quality track record. For these needs, several lighting certifications have arisen to promote the knowledge and skill set of specific lighting requirements. Let’s go into eight of those certifications now, and see what they mean for you and your lighting needs.

Without light, we cannot see, and since so many of our daily activities are inherently tied to our ability to perceive shape, form, color and depth, the technology that creates light has become central to our lives.

Lighting has made much advancement over the decades, regarding the technology to create it, the science of understanding it, and the design sensibility to install and display it for maximum effectiveness. However, there can often be more to the creation and installation of light in a building than just installing wiring, switches and then turning on the lights. Lighting designers are playing an increasingly important role in lighting needs for both commercial and pedestrian areas, and there are several good reasons you should consult them for your space.

To say that energy efficiency is important in the context of a data center is something of an understatement. The Federal Energy Management Program that was created under the Office of Energy Efficiency and Renewable Energy, for example, outlines recommendations for ways that data centers can reduce energy consumption by between 20% and 40% just by applying best management energy-efficiency measures and strategies.
