As is often the case, after attending an engaging and informative continuing education class, I am compelled to share at least a fraction of the energy that I experienced today. When a class is good, it is energizing. This was a most illuminating lighting course!

We know that as interior designers that light plays a significant role in creating a scene. Whether task lighting, ambient lighting, spot lighting or washes of color – light plays an important role. What’s so exciting and compelling is the technology that is so rapidly changing the possibilities!

The profound change is a result of the perfected application of Light Emitting Diodes – LED lighting. Lynne Wilkinson takes the complexity of physics and speaks in plain language with a humorous and entertaining delivery distilling that which is incredibly complex into digestible information.

Here’s a link to Philips for more information:

So today I want to impart a tiny bit of the exciting content of this day. If a child asked you – “what is light?” How might you answer that?  Um…well…it’s uh…Electromagnetic radiation. Duh! After clearing that hurdle, we settled into distinguishing the technology between incandescent and fluorescent and a number of other lighting sources.  We discussed temperature Kelvin, luminescence, illumination and the atomic composition of protons, neutrons and electrons that are involved. So how is this interesting to YOU?

Well…inasmuch as we in the field have kept step with much  of this terminology throughout our careers, and the sci-fi interpretations of the possibilities – the future is HERE! If you just look at I-Phones being only 10 years old, yes, 2007 – we’ve come a long way baby!! Nearly anything you can imagine already exists! And if it doesn’t yet, the brains in the incubators are racing to discover and invent the next iteration of these amazing possibilities!! Look at these cool dots and dashes dramatically streaking across a living room ceiling!

 

You probably know that LEDs are energy efficient. Have you noticed how dramatically their price has come down in the last, say, three years? They used to be $50 and now they are under $10..  They burn for 50,000 hours…but as they diminish, the quality of their light changes – they will burn long after the accuracy of their illumination has changed. Do you care?

So many health issues are still being discovered with regard to the effectiveness of lighting. Circadian rhythms – how your body is biologically on a timer. How it needs rest and waking hours. What interferes with the natural melatonin in your system that can affect your health. Dark is for sleep. Blue light versus red light can interfere with your good sleep? Here’s a hint – don’t leave computer screens or cell phones on in your bedroom – get rid  of the clocks and other light-emitting devices when you are trying to sleep. AVOID the cool colors – blue especially.

To take this to a higher level of interaction, artificial lighting can be “tuned.” We know it can be dimmed and change color – but tuning is the technology of changing the temperature and related color to compliment the activity in the space. Your living room can be tuned to track the time of day to compliment warm early morning, bright cool mid day, dimming down to the warmth of an evening glow. Do you care? Maybe not today – but to better organize and track a busy day, this can be soothing to compliment your morning coffee…energize you into a more productive mode as the day progresses and calm you as the day closes. It might be handy if you lived in Scandinavia where the days are shorter and the desire to create a sense of daylight’s progression is real.

In an operating room – do you want your surgeon to see well into your body parts? By tuning the room in zones, you can place certain colors of light over the surgery to better illuminate and contrast the focal point or dim the light to read monitors better (as in many endoscopic procedures where they go in with a camera and don’t even see the action except on the monitors which are better read with a darkened surrounding quality of light or lack thereof), or brighten other areas where medical implements, keyboards, etc need brighter light to do the job. The understanding and ability to control these various light levels, colors and luminescence is becoming very apparent. Might ultimately be invaluable.

Back to interior design applications and concerns – the idea is to create effective, appropriate light and not see the source. I have always said this especially in the realm of landscape lighting – yes outside. I never use the “runway lights,” rather I chose to conceal the light source and have it spill, wash, spot and filter without giving away the source of the light.  It is more subtle, effective, natural, soft, and pleasing. So in a kitchen, don’t let the under-counter lights be spotty, reflected on any adjacent dark or shiny surface, use smaller aperture ceiling fixtures (cans), hockey pucks in cabinets create shadows…with all the new LED tapes, fixtures and diffusers these faux pas are very avoidable.

As recently as 18 months ago we were remodeling a bar and wanted to use LED tape the full-length beneath the long countertop  – but the cost was significant. Today, that cost is a fraction of what it was. So I might be re-visiting that bar detail!!!

So many lights can be field modified cut and shaped. With the perfection of Organic LEDs, seemingly limitless possibilities exist. Imagine your laptop being so pliable that you can roll it into a tight tube and pack it effortlessly without fear of cracking or breaking. Light-weight and completely flexible. They exist.

Imagine an entire wall in your home that is a touch screen that can be installed as easily as wallpaper. Yes, pliable and paper thin, glued onto the wall and operate as a computer – all your news and information at your fingertips at a scale that commands the room. Smart surfaces – they exist.

Back to now – smart homes can do so much from an app on your phone and lighting is a huge part of that control. You already know that you can turn you lights on and off from your phone on a beach in Tahiti. But did you know that your phone can be as small as a lipstick tube or small flashlight and have a retractable screen of flexible OLED – easy to hold, pack, carry and with a simple tug, click or push of a button reveal a thin full screen? It exists.

Architecture and interior design benefit greatly from this technology, but are probably the last to be jumping on the bandwagon. This technology is introduced in so many other aspects of our world before it gets to mere offices and residences. Fabric panel walls that have lights IN the fabric and can be controlled for color and movement, resin furniture glowing from inside that can be used outside in all-weather, stair treads that sparkle with glass embedded into them and coffee tables that have pressure sensitivity that when you touch them they respond. So many of these creative applications are already very cost-effective and remarkably accessible.

Here is more about glowing furniture from Marceladick:

Glowing ceiling layers that once were inconvenient to replace lamps (bulbs) often were left dark rather than scale the heights to maintain. Now the long lasting light sources produce their glow for many years.

Fashion is also enhanced with the advent of these light sources in the actual fabrics. Models sporting luminous layers, glowing translucence, sparkling luminescence adding elements to clothing imagined. Think about draperies!

Let There Be Light for the New Year!!

Short days and longs nights…Do you find that your interior is dull, lifeless and even feels a bit cavernous after dark? As the sun  sets and the lamps come on, the effects can be horrible, adequate or sensational.

Poor lighting can have remarkable subliminal effects on mood, energy, and attitude. The subtle signs of poor lighting such as dark corners, shadows on faces, difficulty reading and dull colors are all important factors that contribute to an uncomfortable interior in these short days of long, dark nights.

Lighting has multiple reasons for being—three primary ones—to see, yes, ambient light. But to do tasks (reading, sewing, playing games), and accent lighting to illuminate artwork and other interior features. Mood lighting such as candlelight (once the primary light source – now an effect in most cases) is a lesser but effective  lighting tool.  Good lighting makes amazing differences.

Beware of down-lights. Lights that shine down from the ceiling. Although a very effective and common lighting tool, they must be balanced with good ambient light.  I have often used this example of sitting in a restaurant across from your date and their face is painted with ghoulish dark shadows under their eyes, beneath their nose, and accentuating all the folds of their features. It is the opposite of a kid putting a flashlight under their chin shining upward creating similarly haunting effects. Creepy. Certainly not flattering.

The same unpleasant effects happen in the home. It’s such a common malady of ineffective lighting that most people assume it is a necessary evil of short days. It’s sad—no, really it’s SAD—Seasonal Affective Disorder! To treat the serious effects of this syndrome there are many studies and inventive solutions, but for most of us, the less arresting effects of poor lighting can be greatly improved and our lives enhanced.

To begin this process of evaluating your lighting an improving it right away, start with the lamps—the light bulbs! We have so many choices these days including the familiar incandescent, compact fluorescent, and the newer LED with excellent color choices and low energy usage.  We could talk about the “temperature” of light sources measured in Kelvin, but we won’t—only that it runs a spectrum of warm to cool.

Walk around your home and look specifically at the color that glows from the various light sources. Does it look yellow? Does it look white? Does it look blue-ish? Recognizing these distinctions from warm to cool is the start.

Where are the shadows? Are the corners dark and recessive? And, when you combine these two, do you find, for example, dark areas and yellow glowing sources? Sometimes that soft, warm yellow is preferred while other scenes are made more intentionally crisp with cooler light.

Experiment with different lamps in your fixtures – light bulbs in your table lamps and recessed cans, hallway sconces and bathroom fixtures. It’s a fun experiment and very illuminating – yes, the pun was intended.

Are your lamp shades opaque or translucent? Do the shades themselves cast a color? Do they block the light or allow it through? Do they throw the light up and down or up, down and out? This is another detail of which to take note.

If you have dated recessed fluorescent tube units – common in kitchens for example – they are often housed in a box either recessed or surface-mounted on the ceiling. Take a look at the plastic lenses – are they discolored and yellow? This aging process can dramatically affect the quality of light that is emitted. So if you are not ready to replace these fixtures with more effective modern lighting statements, try replacing the lenses.

A similar installation is that of skylights which have fluorescent lamps up inside the wells with that same plastic lens over the opening to the skylight. The original idea was to have the natural light pass through during the day and artificial light take over after hours. The lens  was to intentionally conceal the unattractive fluorescent tubes, but it sacrificed the depth of the framed well. A quick update is to remove the lenses and fluorescents and expose the well of the skylight adding dimension to the room and eliminating the unattractive lens that conceals the dimensional cavity. Recessed can fixtures around the skylight in the surrounding ceiling are the most common solution to this transition from old to new, a cable can be strung, pendants can be hung, but if budget constraints prohibit that investment at this time, you might investigate the power source up inside the skylight well and replace the fluorescent fixture with an inexpensive, adjustable, surface-mounted spotlight – perhaps with two heads to provide light from that same source while opening the skylight well without the unnecessary lens.

The dark pockets around your rooms can be improved with up-lights in corners and up under plants. Inexpensive fixtures are available at any lighting store or big box home improvement stores. Place one of these up-lights (remember to select the color “temperature” that pleases you the most) and see what that additional pop in the corner does to open your space. When up-lights are used beneath plants to shoot upward and cast shadows onto the walls and ceilings can create drama and exotic interest at night. This is true both indoors and out.

Torchiere floor lamps are those that face upward. Like a torch, they send the light toward the ceiling – another effective splash of light in an otherwise dark space in the room.

Colors are radically affected by the color of light that shines upon them. Therefore, an interior color scheme can be horribly tweaked to not resemble at all the actual colors chosen and combined to create the scene, when artificially illuminated after dark. Contrarily, colors can be rendered with great brilliance and accuracy when illuminated with the right combination of lighting. (although daylight contributes in these two examples).

By the same token we can have great fun and “paint” with light creating a color scheme entirely with colored lamps washing the walls, and interior elements just for the art and exercise of doing so, but I digress.

In summary, look around your rooms after dark and look for opportunities to make changes that will dramatically affect the comfort level – the results will be startling!!! If planning new construction or remodel – have plenty of light in key places throughout the space. Think dimmers so you can control the amount of light. Let there be light in this Happy New Year!
