Medical News Today published an article on the effect of room lighting on decision making. Invoking crime dramas in which suspects are interrogated under bright lights, the report suggests that people tend to feel emotions more intensely in brighter light. This finding is significant not just for retailers but for anyone who consciously uses light in their spaces for a desired effect.

Medical News Today’s story is based on research conducted by academics from the University of Toronto Scarborough and Northwestern University and published in the Journal of Consumer Psychology. As you can guess, based on the journal that published the research, findings about how people act under different lighting conditions has important implications for how people act as CONSUMERS.

Here’s how the study went: A bunch of test subjects were asked to rate an eclectic mix of things, from the spiciness of chicken wings to the aggressiveness of a fictional character. Subjects were also asked to assess the flavor of two kinds of juice, the emotional tenor of certain words, and the attractiveness of a person. The scientists changed lighting levels as they observed their participants’ reactions to these stimuli. As the scientists suspected, lighting levels had an impact on how the participants felt about the things they were rating.

According to Medical News Today, previous studies have established that “people are more optimistic about the stock market, report higher well-being and are more helpful during sunny days, whereas being exposed to gloomy days for long periods of time can result in depressive feelings.”

But, then, the researchers ask, why do suicide rates peak during late spring and early summer months? This new study complicates the common belief that more light equals more happiness.

The researchers have concluded that brighter light levels do not necessarily make people happier. Instead, brighter light levels intensify both positive AND negative emotions. In the brighter room, during the experiment, participants felt more positive emotions in related to positive words and more negative emotions about negative words. They found people more attractive in the brighter room AND felt the fictional character to be more aggressive.

It isn’t hard to install new electrical outlets, but it’s important to prep your home accordingly. To avoid any strange scenarios, check out the three tips below:

Before adding a new outlet, you’ll need to make sure your breaker panel is turned off. Double-check that your breaker is turned off with a voltage tester. If you don’t have a voltage tester, plug in a lap to the nearest-available socket. Additionally, it’s a good idea to test the new socket directly by plugging the excess length into an electrical application.

Understandably, you may find it difficult to jab through drywall when making room for an outlet. Instead of cutting with a saw, consider using a flat head screwdriver. It’s cheaper, more adaptable and can easily carve through drywall. If you do settle for a saw, make sure you’re not sawing too aggressively. Aggressive sawing can tear a drywall surface’s paper backside—which will reduce the wall’s structural integrity. If your screwdriver-made hole is too small, you can make it bigger with a utility knife.

If you’re working with fabric-insulated wiring, it’ll be a good idea to contact your electrician. Your electrician can recommend various safe connections, making sure you’re not engaging unsafe projects without a grounding wire. Without a grounding wire, it can be difficult to tell which wires are neutral and hot.

Advanced lighting control systems (ALCS) utilize electronic circuits with a programmable logic controller to automatically adjust lighting levels.  Program a number of variables and light requirements to get the lighting just perfect. This helps in providing the right amount of light where and when it is needed, hence improving energy efficiency and savings.

Advanced lighting control systems provide benefits like automatic scheduling and dimming. Turn lights off based on room occupancy and level of daylight. In so doing, the ALCS adjusts the light levels to match the requirements at any particular time. For example, when a room is empty, lights dim or go off completely. This saves on utility costs.

The sensors communicate with the lighting control system through wired or wireless connections. In some applications, sensors are integrated into the lighting control. While the wired network requires hand wiring of all the devices, the wireless communications use radio frequencies. Therefore several benefits exist over the wired network.

Wireless technology eliminates the need for wiring and is, therefore, cheaper, easy to implement and modify. It provides more flexibility while reducing the planning time for the electrical system. Wireless lighting controls are ideal for hard-to-reach lights. These include places where there are non-accessible or hard ceilings, basements, and other expensive or hard-to-wire areas.

The controller automatically adjusts the level of illumination based on one or a combination of the following variables.

The controls utilize room occupancy or proximity sensors to check for activity in the room or target area. If there is no activity, the controls automatically switch off or dim the lights. The system will then turn the lights to full brightness when room occupancy sensors detect someone within a defined space.

Different lighting levels are required based on the activity. In some applications such as warehouses, there is no need to keep all the lights on when areas are not in use. The lighting control systems will either turn off or dim most of the lights. Some advanced systems provide just enough light in the open spaces. Yet, more light becomes available near shelves where a worker might be picking up or replacing items.

Additional light is required during office hours when people are working. However, this isn’t necessary during the lunch break, or when offices are being cleaned. A combination of controls may be used here. Take advantage of daylight, dim or completely turning off the lights when more natural light filters into the room.

The programmable controls can be used to switch individual or groups of lights depending on time of day. These programs run 7 days a week. Consequently, there’s a separate schedule for weekdays, weekends, and holidays. In an office setup, a timer ensures that all lights, apart from security lights, are turned off at night, during the weekends and on holidays.

Instead of using the lamp at its maximum rating when new, the controls dim the light in certain cases. This reduces the normal wear and tear. As the lamp ages, its level of illumination will decrease. However, instead of the light level going down, the control will decrease the dimming level and maintain the required level of light.

So instead of powering the light at 100% and wasting energy with excess light that is not required, the controller ensures light is powered at a lower percentage. This ensures that required light is provided, but at a lower power consumption.

Factors considered when implementing a lighting system include the need for flexibility, facility size, floor plans, facility use, daylight hours, and building codes. Other considerations include the cost-effectiveness of the system, the ease of use, visual performance and comfort.

In addition to controlling the lights, the advanced lighting control systems help in determining the occupancy patterns. Moreover, the operating status of part or whole sections and the entire system’s performance is monitored. This provides business owners with an opportunity to evaluate the effectiveness of the installation and make adjustments.
