Interior designers are often called upon to give input about lighting in residential environments. In trying to tackle a lighting dilemma, many fixtures get specified in living areas, kitchens and baths that waste energy and do not get light where it is needed most. These ineffective specifications are often repeated as homeowners are unsure of lighting solutions and tricks of the trade. But sometimes, knowing what not to do can help make you look like a pro. Below is a list of common lighting mistakes, so that you can avoid them from the get-go, and attain the perfect lighting for your home.
Kitchen Mistake 1: Installing recessed downlights everywhere. This is one of the most common errors that lighting design professionals see. Builder spec versions of can lights can be very inexpensive, and people often assume that laying them out in a regular grid gets light everywhere. Unfortunately, this is not so. With an array of cans, we might waste nearly half our watts and still have a space that feels like a cave because the walls are dark. The kitchen should have the perfect amount of layered light over the island, as general overhead light and for task lighting under cabinets.
Kitchen Mistake 2. Forgetting task lights in the kitchen. There are many better ways to light the counter, and one of them is to use fluorescent (T5), xenon or LED task lights under the upper cabinets. If your kitchen design lacks upper cabinets over some work surfaces, don't worry. This is a situation where wall-mounted or ceiling recessed adjustable fixtures with the right lamp make all the difference. Adding several low voltage halogen fixtures with a narrow flood beam distribution and focusing them on the task area will do the trick. Remember to choose your fluorescent or LED color temperature wisely.
Kitchen Mistake 3. Neglecting to control different types of light separately. For maximum efficiency and flexibility, each type of light should be controlled separately, and any incandescent or halogen light, or dimmable LED's should be dimmed. Controlling multiple sources can be achieved by multiple light switches, but there are many more sophisticated ways to achieve control. From a simple programmable wallbox system for single room control with preset scenes, to wireless controls that generate their own power and can be reprogrammed from a laptop or phone, controlling the lighting yields energy savings combined with the right amount and type of light for different times and uses.
Bathroom Mistake: Using downlights over the vanity without adding lights on the side. Standing directly under a downlight, without any light at the sides of the face, creates exaggerated and unflattering shadows. In the bathroom, using a downlight over the sink is fine to accent the expensive polished nickel faucet you've specified, but it's insufficient for tasks like shaving, tweezing, and applying makeup. For this, we need light at the sides of the mirror at eye level to minimize shadows and provide even distribution. This can be achieved with sconces flanking the mirror.Mirror sconces and overhead cans on a dimmer create the right effect.
Hallway Mistake 1: Using incandescent or halogen sources without dimming. While we are all finding ways to retrofit lighting with more efficient, longer lived light sources than incandescent, it is still a viable and important part of lighting in a residence, provided it is dimmable. By dimming, we decrease energy and heat output, and we lengthen lamp life. Hallways should have dimmable wall washers and overhead lighting creates a mood while lighting a pathway.
Hallway Mistake 2: Forgetting to incorporate ambient, task AND accent lighting. Lighting designers understand that all well-designed spaces incorporate different types of light. Ambient light is general lighting for walking around, conversing, and identifying objects. Task lighting provides higher, more concentrated lighting for tasks such as chopping vegetables, shaving, or reading. Accent light is used to highlight artwork or architectural features, such as the beautiful glass tile you’ve specified in the bath or the ceramic collection your client will showcase in open shelves in the kitchen. Combining all three types of light gives greater functionality, interest, and likelihood that you will have sufficient lighting. Hallways should highlight show pieces, read a book and illuminate a hallway. You simply know it when lighting is done right.
Ceiling Mistake: Putting recessed downlights in a high ceiling for ambient light. This results in a lot of wasted light and a very dark space. Light originating at high ceilings needs to have a very focused, tight beam spread with enough center beam candle power, such as that from a ceramic metal halide or high wattage halogen source. Better yet, using wall-mounted or pendant sources to reflect light off a light, matte ceiling surface often provides much better illumination than punching a lot of holes for recessed downlights.
Lighting Fixtures Mistakes In General: Decorating with light. Lighting designers think about light as an actual dimension, imagining the distribution and output from each fixture, as well as the quality of the light and color. Decorating with light fixtures, or choosing fixtures based on how they look rather than their light output, performance, and distribution often results in a waste of energy and less than optimal light output. For assistance with architectural light fixture choices, consider hiring a professional lighting designer who can transform your space through light, while providing adequate task lighting and often saving energy.
