Indoor Light Pollution

My last blog entry pointed out how traditional outdoor lighting is poorly designed and creates significant light pollution. The culprit is the traditional incandescent light bulb, which emits light in all directions. The CFL bulb copied the incandescent bulb and also emits light in all directions. The result is a lot of wasted light. Why are millions of lampshades sold every year? If the light bulbs were emitting light only in the desired directions, then lampshades would be irrelevant. Other light fixtures that use traditional incandescent and CFL bulbs are providing more light into your eyes than illuminating the floor and walls.

LEDs are designed to shine with tighter directionality. The majority of indoor lighting applications – down-lighting; lamps; sconces; track lighting; ceiling lights; wall-mounted lights – need to emit light over less than 180 degrees. Thus LEDs area better match for most indoor lighting applications. LEDs are more efficient and create less indoor light pollution.

Mr. Beams makes a number of energy efficient LED lights. The motion sensor battery powered Ceiling Light has a bright LED that emits at a 120-degree angle. This tight beam is perfect for lighting closets, sheds, crawl spaces, attics and porches without creating light pollution. The Mr. Beams motion sensor Ceiling Light mounts easily in minutes without an electrician because it is battery powered. It operates for about $1 per year.

The Stick Anywhere Night Light prevents light pollution in your hallways, stairs and bedrooms. Instead of lighting up all night and interfering with your sleep – as most night lights do - the Mr. Beams motion sensor Stick Anywhere Night Light stays dark until it detects movement. At that time it provides the perfect amount of light to prevent falls, but not so much light that it disturbs your sleep mode.

That is the definition of the perfect indoor light: it is on only when you need it and it lights up only what you need illuminated for safety and security. The Mr. Beams battery operated LED lights provide light only when it is needed and only where it is needed. These LED motion sensor lights come in four designs: Spotlight; Ceiling Light; Stair Light; and Wall Light.
