“If there is one single positive change that pet bird owners can make, it is returning the bird to a regularly recurring photoperiod. Whether in the wild or captivity, most birds demonstrate a remarkable periodicity to their days. Restoration of a regular recurring day and night cycle usually results in a happier and healthier companion bird. Birds have in their brains a finely tuned, light sensitive pineal gland. This gland is likely the mechanism by which birds set their circadian rhythm.”
Each bird species is different and benefits from its own particular photoperiod. A safe starting point is 10 hours on; however, the best course of action is to conduct online research or ask your avian vet about the best photoperiod for your bird.
The most important thing to know about EM waves is - as their wavelength changes, their effect on living organisms also changes.
For example, you can see in the image below that the longest waves are radio waves and quite harmless. As the wavelengths get shorter, they become harmful radiation.
Most EM waves are man-made; however, this article is about how artificial light compares to sunlight, so we will discuss EM waves that the sun produces. These EM waves have a wavelength between 100 and 1,200 nanometers.
The longest wavelengths that the sun produces are Infrared waves, otherwise referred to as heat. The shortest wavelengths are UVC, which are 100% filtered out by the Earth’s atmosphere.
Ultraviolet waves between 280 and 400 nanometers are further broken down into categories A and B because the effects they have on living organisms are very different.
Within the visible spectrum, each wavelength is a different color. Light works by bouncing off of objects and into our eyes. When a light that contains wavelengths in the red spectrum bounces off of a red shirt, our eyes see red. If the light does not contain red wavelengths the shirt appears as a different color to our eye. That color depends on the wavelengths present in the light.
Therefore, a light with more wavelengths present is likely to make an object look more natural.
There are a limited number of colors in the visible light spectrum, but when they’re mixed, they produce different colors—much like mixing paint. Scientists estimate that the human eye can see over a million colors, which can be made by mixing various wavelengths of color. If a light were to contain an equal amount of every wavelength, the result would be white light. However, light rarely contains every wavelength, and it’s the mix of wavelengths present that determine the final color. Final color is measured by the Kelvin Scale (K).
When you purchase a light in the store, somewhere on the package will be the light color followed by the temperature in K. A regular household light, for example, is typically a yellowish light at about 3500K. The reason why light is measured in Kelvin rather than nanometers is because it represents the final color, not the individual wavelengths it contains.
The important thing to remember is that the K rating of a light is its final color and does not represent which wavelengths are present in the light to make the final color.
The color of light can be measured by an instrument called an optical spectroscope, which produces a report, called a spectrograph, as shown below. Sometimes a light will have a spectrograph on its packaging.
The written parameters of the report can be confusing, but if you look close you can see that this light is around 6,500K with a CRI of 94.
For the purpose of this article, the graph on the left contains more valuable information. It is a quick glimpse of which wavelengths (colors) are present in the light and at what intensity they are. As we learned above, in the graphic with the red shirt and blue shorts, the more wavelengths that are present, the more natural objects will appear to our eye.
For a fun reference, here is a spectrograph of the sun at noon on a cloudless day. The difference is pretty clear.
Mark Schack presents seminars on bird lighting at avian events around the country. Though without formal education in avian health, Mark is a mechanical engineer and lifetime hobbyist of breeding pet birds. Frustrated by the lack of availability of good lighting, he decided to build his own. The above information was gathered during Mark’s attempt to build “the perfect light” and through continued study of the subject.
