DIY - Lighting – Bedroom Lighting Guidelines
Good bedroom lighting considers a careful mixture of practical and psychological factors. The average bedroom has so many different uses - relaxation, intimacy, study, morning preparation - that covering them all can be tricky.
We associate the bedroom with, among other things, sleep. That usually means no lights at all. That suggests that turning them off should not be a chore. If you’ve been lying in bed reading it can be inconvenient to turn them off, especially if you’ve grown sleepy. A master switch within easy reach is a great idea here.
That nighttime reading can be a strain on the eyes, leading to fatigue and headaches. Banish the problem by installing lights in the proper places with the correct color.
Color? Does that mean you should get pink or blue light bulbs? No. Color, here, means ‘color temperature’. Good reading lights are designed to emulate the range of wavelengths given off by natural sunlight, which is determined in part by the temperature of the sun’s surface. Humans’ eyes evolved to be sharpest under those conditions. Getting bulbs and lamps labeled as close to that will provide comfortable reading conditions.
But sometimes, you just want a pleasant ambiance, not a practical light. That, too, should be taken into consideration when designing the bedroom lighting scheme.
Select and place lamps about a foot higher than where your eyes are, and allow them to reflect light off surfaces. That provides the well-known indirect light effect that gives a subdued atmosphere. Whether for romance or just a quiet time away from distractions, that produces a calming effect that is just right in the bedroom.
Morning time is when most people, both kids and adults, will be up and preparing to meet the day. But, depending on the time of the day and season of the year, the sun doesn’t always cooperate to provide the illumination needed. The orientation of the house plays a role, too, as do any curtains, exterior overhangs and so forth.
To provide a cheery atmosphere that also provides needed light to tie shoes, connect a tricky clasp, brush hair or do any other common task, place lamps appropriately. Here again keep the light above the eyes, but let it shine directly down. Raising it too high creates deep shadows that can hinder makeup application, make clothing color judgment more difficult and so on. Too low and it shines in your eyes, making those tasks harder. Choose a pleasing middle level.
For overall illumination - for entering the room, vacuuming and a hundred other common tasks - a broad ambient lighting scheme is needed. A central fixture with a strong lamp and a diffusing cover is often just the thing. For other bedroom designs supplemental lighting fixtures will be needed. There are often lots of corners, nooks and other areas of a bedroom that can have deep shadows.
For all of the above applications a dimmer switch, or at least multi-level bulbs, can allow for finer control of light and shadow. They can also allow for some small electricity savings if the light stays on for extended periods. A 300-watt halogen bulb can contribute a chunk to the monthly bill. Dimming it when lower illumination is enough slices that down.
Consider all the ways you use your bedroom and light accordingly.
With the return of warmer weather, homeowners often plan home improvement projects and many look for ways to do them with minimal impact on the environment.
