To Light or NOT to light?

When moving in or remodeling, homeowners are wise to focus on the power of light to illuminate rooms, add decorative panache and color, pare energy consumption and improve safety.

Key Takeaways: Make lighting a priority rather than an afterthought in your renovation and redecorating plans.

• LED innovation has expanded considerably over the years, offering an affordable and energy efficient option for lighting.

• Add lighting in multiple layers for greatest functionality, aesthetics and mood making.

So much of the time, plans to decorate or fix up a home focus on big fun projects such as kitchens, bathrooms, paint palettes and furnishings. Other projects, like lighting, are often an afterthought.

Choosing where to cut holes for recessed ceiling cans or install light switches in walls may seem ho-hum and boring, “but these decisions and others should be part of any plan because there’s so much new lighting technology to take advantage of,” Case says. Technology isn’t the only reason to keep lighting at the forefront of design plans. Thoughtful light decisions made early on can both help save money and time and limit mistakes. For example, adding recessing cans to a ceiling after it’s been painted might require rewiring and repainting. Getting Started “Start thinking about your lighting design as early as you consider your overall vision for your home,” designer Avraham Mor, CEO of Chicago-area Morlights, advises. “Lighting has one of the most significant impacts on how your spaces come to life.”

Do Your Homework and Make a Plan Like many industries, the lighting space has changed to accommodate new technology, energy needs, and styles. Do a bit of research on what’s available. Consider your design preferences and how far you want to move into the technology space when it comes to lighting. Remember to also consider how much natural light a space gets, Mor says. Learn About LEDs

Even though they’re not new, the buzzword in the industry is still LEDs. The light emitting diodes are responsible for many improvements, including energy efficiency. In today’s market, they come in a range of colors and can be programmable. In many cases, they can be controlled from an app on a phone or by voice command. “LEDs have been around for years but became more popular in late 2009 to 2010, when they replaced compact fluorescents,” Lauck says, adding, “Each year, they’re more sophisticated and better quality.” Among their pros:

• They consume less energy. In fact, they’re so energy-efficient that the Department of Energy announced plans this past April to phase incandescent and halogen bulbs out of production and sale in the U.S. before a ban takes effect next year.

• They cost less. After initially emerging as a pricey option, many LEDs cost about $1.50, down from $80 apiece in 2008, says Nathan Kipnis, a Chicago and Boulder, Colo.–based architect and expert on sustainability.

• They last longer. Lauck says he used to replace a porch light monthly and now expects its LED replacement to last 10 years. Joseph A. Rey-Barreau, lighting designer and associate professor at the University of Kentucky, says LEDs typically last from 10,000 to 50,000 hours of light. For maximum longevity, he says, “don’t skimp on quality.”

• They’re smaller. Let’s face it: Sometimes lightbulbs are a bit of an eyesore. A ceiling with recessed cans can have apertures of one inch in diameter—versus the standard five or six inches from years back—so it minimizes the look of holes in a ceiling, Rey-Barreau says. They also come in narrow, less visible “ropes” for all sorts of architectural applications, Lauck says.

Visit a Retail Showroom Nothing compares to viewing lighting options in person. If you’re uninterested in a big-box store, some have a lighting lab, which demonstrates products in vignettes that simulate rooms.

Even if a homeowner can’t visit a lab, experts at most showrooms are trained to demonstrate options. They can help most if homeowners bring specifics, such as a floor plan or rough sketch of the room in question. It’s even better if the measurements and placement of doors, windows (since natural light affects how artificial light looks) and furniture are sketched in, says Shawn Carstensen of Wolberg Lighting Design & Electrical Supply in Kingston, N.Y. “I’ll ask what the function of the room is, how they want it to look, and what type of light they may want to see—a wide beam or crisp focus,” he says.

Develop a Lighting Plan With a pro on board, a homeowner can have a lighting plan drawn up. “It’s less expensive to work from a plan rather than piecemeal and have someone come back multiple times or have to correct mistakes,” Lauck says.

When preparing a plan, architect Nicole Semple, principal with Chicago-based Kuklinski + Rappe, says she and colleagues focus on using LEDs, automation, dimming, and mixing light layers for maximum effect.

Case includes lighting suggestions in her plans and elevation drawings and then has her contractor or electrician fine-tune them based on the fixtures and bulbs that will work best in each room.

A homeowner’s age and physical challenges may also come into play. “If they are getting older and have poorer eyesight, they may want different lighting to illuminate a path to a bathroom at night or into a kitchen to grab a glass of water,” Lauck says. Wheelchair users may want switches at 48 inches above a floor rather than at 52 inches. And then there are other decisions such as the choice of fixtures, baffles, lenses, and housings (the protective covers for cans) and the number of switches.

Considerations for The Project Once the learning and planning is complete, it's time to get the project started. There are still a few considerations to make in order to ensure you create the look and ambiance you want.

Hire a Pro Even if a homeowner opts not to work with a retail store’s lighting professional, hiring an expert is a good idea.

An electrician is necessary as well, as most electricians will check if they need to upgrade an electrical panel for more light. They’re also knowledgeable about the National Electrical Code and local building codes.

A homeowner should ask upfront about charges. Some showrooms may provide a consultation for free or for a fee that’s refunded with merchandise bought, says Rey-Barreau. An independent designer may charge by the hour or by the project. Some interior designers and architects include lighting ideas in their services.

The Rule of Three The best plans feature a mix of three layers of light that work together to make rooms function and look great, says Rey-Barreau. “Some rooms may have more layers to offer the chance for a more custom look,” he says.

• Overall or general lighting illuminates a room and helps it come alive. If the room lacks natural light, artificial light becomes more important.

• Task lighting illuminates where work is performed—a computer screen in a home office, a mirror in a bathroom, or at a kitchen countertop, Lauck says.

• Ambient creates a specific mood—bright and perky, soft and romantic, or fun and colorful.

Color and Intensity Homeowners may think of wattage equivalents first when choosing lighting, but that term refers to the energy a bulb puts forth. The Kelvin scale measures the temperature of the light and is important since light colors aren’t all white, off-white, or yellow. They should be matched to function and mood.

For other moods, you might desire a bluer light, from 4000 K to 6000 K, Lauck says. The good news is that you can find a LED for any color of the rainbow.

When It’s All Said and Done Even if you haven’t made lighting a priority, it’s not too late to add or change it. “It’s just harder and more costly to make changes as a project gets to later phases,” Grubb says—or after it’s done.

Bear in mind the goal of achieving balance with lighting. If too many lights are on at once, the light can wash out important design elements and distort colors, Mor says.
