How Much Screen Time is Too Much?

While most of the discussion on the dangers of technology on children is centered on personal security risks, there have been, for quite a long time, concerns about the health risks posed by screen time. In particular, parents are mostly concerned about their kids potentially messing their sleeping patterns from watching too much TV, or endlessly playing video games. These fears have fortunately been allayed courtesy of a recent study by Oxford University's Internet Institute.  According to the study, screen time does indeed affect children's sleep time but not to a considerable extent. In context, the average sleep time for [...]

Improving Visual Comfort

The amount of light provided by the sun meets the minimum requirements for illuminance, as set by the IES. Besides, it renders daylight harvesting uneconomical, at least quantitatively. This means that measures need to be put in to improve visual comfort. Most people use daylight to illuminate spaces. However, they still install diffusers, louvers, and prismatic lenses to reduce the glare produced by the sun's rays. If you have ever driven at night, you probably know that the glare from an oncoming car’s headlights can be blinding. Surprisingly, this doesn't occur during daytime when your eyes are light-adapted.  However, in [...]

Following Advancements in Lighting Control Technology

The National Association of Lighting Maintenance Companies (NALMCO), in partnership with the Illuminating Engineering Society (IES), oversees and certifies lighting maintenance companies operating within the US. The two organizations form the Joint IES Lighting Maintenance Committee, a body that creates lighting industry standards, including RP-35-15 and the new Certified Lighting Controls Professional (CLCP) certificate.  CLCP certification recognizes expertise in the control, design, and application of networked lighting control systems. A CLCP certified lighting technician acquires comprehensive knowledge in two core aspects of advanced networked intelligent lighting, namely: Troubleshooting, repair, and maintenance of miniature onboard electronics used in achieving precise and [...]

Conserving Energy Levels

Energy conservation, especially in regards to lighting, can be analogically explained using the example of a highway bridge. Basically, it is more practical and economical to lower the river or sea below a giant bridge as opposed to raising the bridge itself.  Similarly, when you need to reduce a lighting load, you ideally target, and adjust both the visual task size and contrast. To effectively measure these parameters, we use the Relative Visual Performance (RVP) index. According to the index, the RVP reading shoots up with an increase in contrast, no matter how slight.  Further, when dealing with 10-point types, [...]

 A Growing Demand for Networked Controls

The National Association of Lighting Management Companies (NALMCO) has always had a mutually beneficial relationship with the International Electrotechnical Commission (IEC) for over 20 years. The two organizations have worked together as part of the IES Lighting Maintenance Committee, coming up with valuable guidelines that touch on lighting maintenance. Following advancements in lighting control technology, NALMCO has launched a new certification that recognizes expertise in this sector. Previously, professionals in lighting control technology did not have certification specific to their trade, hence the Certified Lighting Controls Professional (CLCP) is a fresh break from the past. The knowledge gained from this [...]
