When designing spaces, the first goal is to define the space and primary use of that space. “In an office setting, lighting should encourage alertness and productivity,” says Rebecca Hadley, manager of Eaton’s SOURCE lighting education center.
“It’s also beneficial to incorporate controls that allow for changes throughout the workday. Ideally, you’d have the ability to adjust the intensity of your lighting. Industry research also suggests indoor light should mimic the color of light we experience outside, which follows an arc from cool light in the morning, to white light at midday, to warm light in the evening.”
Though lighting at home is mainly tied to user preference, research shows there are steps everyone can take to create a calm, pleasing environment.
“At night, lower light levels and warmer color temperatures – those that fall in the 2,700 to 3,000 Kelvin range – emulate the outside environment’s evening light and help us get ready for sleep by reducing our blood pressure and creating a restful feel,” said Hadley. “If you’re cooking or entertaining guests in the evening, you may find that higher light levels and color temperatures are beneficial. However, people generally tend to prefer warmer light at home.”
Flexibility is one natural benefit of smart lighting design. New advancements in Lighting Controls have made lighting for mood easier than ever.
“Studies show that wall color can affect heart rate and irritability levels, but you can adjust your light more readily than the paint on your walls,” said Hadley. “For example, you can use high-intensity light to complete a craft activity at the kitchen table; an hour later, you can serve dinner to your family at that same table beneath a warmer, lower-intensity light.”
Newer LEDs with integrated controls and the ability to dim to warmer color temperatures are becoming popular in the hospitality industry because of their ability to affect the customer experience. For example, many restaurants lower their light levels between lunch and dinner as a subtle way of encouraging their patrons to linger over meals. “Warmer light and lower light levels have been shown to slow heart rate and create a relaxing state,” Hadley said. “As a result, customers might be inspired to enjoy appetizers and cocktails rather than rushing through to the main course.” Conversely, some restaurants might put brighter light in an area where they want to turn tables quickly.
When it comes to designing for mood, advanced controls have the most room to develop. Controls will become more personalized in environments ranging from the home to offices, hospitality settings and health care facilities. Controls that were once accessed via a wall switch are already making the jump to app-based technology. And as LED technology improves at lightning speed, adaptability – and energy savings – will only continue to grow.
David Hakimi is a lighting consultant and co-founder of Alcon Lighting. The UCLA graduate works to achieve energy-efficient lighting, enabling architects, designers and lighting engineers to upgrade from outmoded lighting. David takes particular pride in Alcon’s design, energy and building knowledge, tracing his and Alcon’s commitment to quality, innovation, accountability and value to lessons learned from his father, a Southern California lighting salesman and consultant for more than two decades. Passionate about protecting the environment, David is especially adept in assuring that each client and customer meets both rapidly-changing building codes and project goals.
If the work of lighting design was just left to services engineers to meet regulation-determined illuminance criteria per application, then interior and exterior architectural spaces would become soulless environments. Using qualitative measurements, architects and lighting designers can make sure the architectural intention and aesthetic character of a space is not compromised.
The science of measuring light, photometry, specifically applies to light in a space. Photometrics gauges how humans perceive light — its coverage area, where light cuts off and the intensity of light in relation to distance from the light source. In practical terms, photometrics shows whether a lighting plan meets the qualitative and quantitative lighting requirements for a project.
Products can demand attention with the help of proper lighting. This means an open floor plan with tactical attention to lighting fixture placement, brightness, color temperature, and CRI. The ability of LED Lighting to meet these technical requirements is what makes it the #1 choice of lighting designers and architects.
For the versatile, upscale look, designers often recommend trimless recessed lighting. The term trimless recessed refers to recessed lighting which contains no visible trim ring. The installation of trimless recessed lighting is more involved. Here are tips we believe will help ensure a clean, professional installation.
It is a truth universally acknowledged that store dressing rooms are every woman’s worst nightmare. The number one complaint voiced by women and men everywhere is that the lighting is harsh, glaring and reminiscent of the dentist’s chair or perhaps a police interrogation room (“No, officer, I did not realize that pairing Converse with Versace was a crime against fashion”).
