What does nM (nanometers) or wavelength mean with respect to the color of LEDs? This chart will give you a basic idea. Note that color rendering in browsers is different one to the other and the ability of your monitor to produce color. Intended for a basic idea and is by no means exact.
This page was originally created a number of years ago for our customers designing their own LED products. At times, a particular color was needed for design purposes or a particular wavelength for research purposes. Peak wavelength is an important specification found on all discreet LED data sheets. This is still a very pertinent topic. However, over the years, we've had many questions from customers about color in and of itself. What color is beneficial to use in given applications? Therefore, the information on this page has been expanded.
First for the purposes of developers and research, the wavelength chart:
And about those other color questions:
White LED sources are measured in Kelvin and not in nanometers. The lower the Kelvin temperature, the warmer a white LED light source appears to the eye. Most of our LED light bulbs and fixtures are available in Kelvin temperatures ranging from a very warm, almost candle-like 2700K on up to a crisp white 6000K. Which of these you should choose depends on a number of factors. What is the other lighting in the room like? Do you still have a lot of warm white incandescent light sources? Then you would opt toward the warmer Kelvin temperatures in your LED lighting. Do you have perhaps fluorescent lighting? Then the 5000K cool white would blend in better with those. You might also consider the color scheme of the room you are decorating. Warm tones such as dark wood, reds, oranges, and tones of brown and beige blend better with lower Kelvin temperatures. Blues, greens and rooms with perhaps a lot of stainless steel look better with mid to high Kelvin temperatures. It's always best to measure twice and cut once, so if you 're considering relamping, try one of each Kelvin and see what is most pleasing to your eye in the environment where you will be using the light sources.
Colored LED lighting has become more and more popular. Color is not only a necessary part of a business environment to draw attention and add interest, but it is increasingly used in homes to create ambiance. Flexible LED strip paired with our creative crown molding for example, can add either a dramatic or a subtle effect. A bit about colors and using them effectively:
Black: Black is timeless. It can also be formal. Think in terms of a black tie event. Black can fit into almost any design. It can add contrast and can also make other colors stand out. Black goes with everything.
White: White is also timeless and goes with anything. It reflects a lot of light, so the ambiance will be pure and clean, bright and simple.
Red: Amore, the color of love, red is emotional and stimulating. As you know, we use red in our stop lights and traffic signals because it definitely attracts attention. So make sure any red elements in a room are perfect because that's the first thing they eye will be drawn to.
Blue: The color of the sky - it's peaceful and tranquil. It's a great color choice for bedrooms because of its soothing effects. Using blue in a work space promotes tranquility and can increase productivity. It's been said that blue decreases the appetite, so it may not be a good choice for restaurants or dining rooms.
Green: Green speaks of nature: dew sprinkled grass and the smell of a freshly mowed lawn. It's a very easy color on the eye and is also associated with safety. Green is a very good choice for bedrooms, sitting rooms, waiting rooms or anywhere you want people to feel relaxed and safe.
Yellow: The color of caution yet it can also appear sunny and cheerful. It's the most difficult color for the eyes to process and studies show that people lose their temper more easily in yellow rooms than in rooms of other colors. Think of using yellow as an accent and not as the main color of a room or work space.
Orange: Orange bespeaks of the tropics. It has the features of red and yellow - energy plus cheerfulness. It's a color that stimulates mental activity so is great for an office or work space.
Brown: The color of the earth brings us to our roots. Yet an over-use of brown can actually make people feel sad. So blend those warm wood tones with happier, uplifting colors.
When all is said and done, ask yourself what colors make you feel good. Don't make your paint choices from one of those tiny chips at the paint store. Buy a sample size can and paint a good size square on a prominent wall. The color on the chip can look very different than it will in your actual room. And as to colored LED lighting, try a small piece before ordering to accent light an entire room or building. In the long run, you will be glad you did.
