Light Pollution

Q: What is light pollution?

A: Pollution can be anything. Something that one can avoid, something that doesn’t do you good. So light pollution is a kind of pollution, if it interferes with things that you want or need to see. For example, why don’t you see stars at night in a city, when you see millions of stars when you go to the desert or the mountains? The reason is all the light pollution that exists in a city.

Q: So does all artificial light count as light pollution?

A: One can get carried away. Lighting allows us to see. That’s important. But when lighting inhibits your ability to see efficiently, then that is light pollution.

If you want to see the stars, and at the same time you also want to have lighting around you, you want the lighting around you not to be pointing directly at your eyes. When there is zero light, your eyes are at their most relaxed state; the aperture of the eyes is the most open. As light comes toward your eyes, the aperture starts to close.

A typical example is when you’re driving in the evening as the sun is setting: You put down the car’s visor to block the light coming from the sun. Even at nighttime, when cars are coming from the other direction, it inhibits your ability to see the road, because your eyes can’t accept so much light.

Q: Where’s the line between useful artificial light and light pollution?

A: Artificial is light that we control. Much of it is light pollution, though not all of it, because the very fact that it’s artificial light means that we – or some of us – considered it useful enough to create it. We have lots of artificial light all around us: at work, at home, in our offices and schools, on our streets and roads, in our shopping environments.

Q: How much light is enough?

A: The right amount of light is sufficient lighting on the objects that you want to see, and as little as possible coming into your eyes. It’s just what’s comfortable for you. That’s a personal matter. But of course it’s complicated, because one person’s useful or necessary artificial light is another person’s light pollution.

What’s the right color of LED Lighting for YOUR household?

We asked over 40-Year LED Expert, Pervaiz Lodhie, “What’s the right color of LED Lighting for someone’s household?” He answered!

Almost every household has been affected by recent dramatic advances in lighting technology. In recent years, LED lighting has become so affordable that it’s now becoming popular for household uses. Many people are not well informed about how best to use it in their home. Fortunately, you don’t need to take an interior design course to be able to make some basic decisions that will make your rooms more attractive and comfortable.

You can use LED lighting to enhance your home’s décor in ways that were not possible in the era of traditional incandescent home lighting. The color of LED light can range from “Halogen warm”, “Warm White”, “Natural or Daylight White”, “Pure White” to “Cool White”.  Old-fashioned filament or incandescent bulbs never came in any color but warm. The greater a light bulb’s wattage, the more it shifts toward what is known as daylight white. Lower wattages like 15W and 25W are warmer. With traditional incandescent lighting you couldn’t control the warmth or tone of the light, except by choosing which wattage of bulb to purchase.

A majority of respondents to a recent LEDtronics poll said that they prefer a warm white (generally ranging from about 2700 to about 3000 Kelvin Temperature) rather than a cooler white. It’s important to think through how you use and present the different rooms in your home. Generally, warmer colors are softer on the eyes. On the other hand, human vision is more efficient in brighter light.

If a room has a lot of woodwork, or if your floors are stained or carpeted in warm colors like beige or brown tones, then you need warm light. Warm light enhances warm colors like red, orange, yellow and brown. If your curtains are warm colors, then warm light will show them off to best effect.

On the other hand, if the predominant colors in a room are cooler contemporary colors such as gray, black, or blue, or if you have white walls, then LED lighting in a pure white is best. If you have those colors – or a lot of chrome and silver – in your home, then warm light will not do justice to their beauty. What you see is not an object itself but the reflection of light off of that object, so warm light will not enhance the beauty of cool-colored objects. Thus for whites, grays, silvers, and blues, you want a pure white light to enhance them. If you put a warm light on a shade of blue, then you will be trying to shift it in an unflattering way.

All colors have multiple shades and levels of warmth, so the ideal light will vary for each shade. In addition, every room has multiple objects that reflect light differently depending on their colors. If a room has a basic light that’s warm, but certain objects in it (such as paintings) contain blues or other cool colors, then you will want specific color spot lighting that focuses only on the painting, without interfering with the room’s overall warm lighting.

Curtains are important to a room’s overall décor and thus to its lighting needs. So are walls. If the ceiling and walls contains a lot of architectural features, then you will want light that enhances those features. If you have a beautiful rug, but you light everything in the room to the same level of intensity, then the light will not present the rug to its best effect. If you have both warm and cool color combinations, what is known as “daylight white” (about 4000 Kelvin) is best.

On the other hand, if you have a garage or general storage room, you want to see everything in it. A garage needs cool white or daylight white, since the human eye sees better in cooler colors. Your peripheral vision is much better in natural white light, and your vision is more efficient when it perceives light to be brighter. Thus LED tube lights and LED CFLs (compact fluorescent lights) in natural daylight white are ideal for your garage, laundry room, or storeroom.

You can greatly enhance the feeling of your rooms by selecting the right color of LED bulbs, and by pointing the lighting in the right directions. You’ll make the most of your room’s décor, and you’ll make the room itself come alive.
