Fully shielded light fixtures come in a wide array of choices and can be used in different lighting situations. It is ideal for both commercial and residential properties. The good thing about fully shielded lights is that the light is directed to the ground so it reduces light pollution. Moreover, it is designed with various technologies like sensors, timers, and dimmers.<\/p>\n\n\n

What Are Fully Shielded Light Fixtures For?<\/h2>\n
Fully shielded light fixtures are designed to help reduce light nuisance and pollution. It helps prevent light trespass and glare which can be a problem for neighboring properties.<\/strong> Unshielded lighting fixtures emit light that travels further and can cause a problem to the neighbors. Take note that glare can cause discomfort or even temporary blindness. Furthermore, a fully shielded light fixture helps reduce sky glow.<\/p>\n Fully shielded light fixtures are ideal because they are dark sky friendly. It is designed so that light is directed to the ground.<\/strong> A fully shielded light fixture features a light source that is recessed from the bottom of the fixture. It has an opaque top and sides. Aside from making sure that the light is only directed into the ground, it prevents light from escaping upward or outward. We have also written this article that discusses what is considered light pollution<\/a>. Check out the article for more information about the topic.<\/p>\n Good exterior lighting should have the right color, brightness, and shielding. When shopping for exterior lighting, make sure that you check if it is dark sky friendly.<\/strong> There is a wide array of fully shielded lighting fixtures sold on the market. Compare one product to another so that you can make the best choice.<\/p>\n The full cutoff is often used to refer to fully shielded lighting fixtures. On the other hand, take note that both are not equivalent. For starters, fully shielded lights do not give off light upwards, but they do not have any limitation when it comes to the intensity in the region between 80 and 90 degrees.<\/strong> Moreover, light fixtures that fall under the IESNA definitions of cutoff, full cutoff, semi cutoff, and non cutoff can be considered as a fully shielded light<\/p>\n The full cutoff is used to describe light fixtures that do not have direct uplight. On the other hand, the Illuminating Engineering Society of North America or IESNA requires light fixtures to comply with the glare requirement.<\/p>\n The four classifications of cutoff lighting are full cutoff, cutoff, semi cutoff, and noncutoff.<\/strong> Let us learn more about each classification below.<\/p>\n The full cutoff is a classification of cutoff lighting with a luminous intensity of zero at or above an angle of 90 degrees above nadir. Moreover, it has a luminous intensity that does not exceed ten percent of the luminous flux of the lamp in the lights at or above a vertical angle of 80 degrees above nadir.<\/p>\n Semicutoff has a luminous intensity that does not exceed five percent of the luminous flux of lamps at or above an angle of 90 degrees above nadir. It has a luminous intensity that does not exceed twenty percent of the luminous flux of lamps at or above a vertical angle of 80 degrees above nadir.<\/p>\n This cutoff lighting classification has a luminous intensity that does not numerically exceed 2.5 percent of the luminous flux of lamps at or above an angle of 90 degrees above nadir. Aside from that, it has a luminous intensity that does not exceed ten percent of the luminous flux of the lamps at or above a vertical angle of 80 degrees above nadir.<\/p>\n For this cutoff lighting classification, there is a candela limitation in the zone above the maximum candela.<\/p>\n To have dark sky lighting, you need to use shielded lights, install LED lighting, and reduce light waste by using motion sensors, timers, and dimmers.<\/strong> The Dark-Sky movement is led by the International Dark-Sky Association or IDA. They aim to lessen the damage caused by light pollution. Below are some of the ways that you can implement dark sky lighting into your outdoor property.<\/p>\n One way to have dark sky lighting for your property is by using shielded lights. Make sure to choose dark Sky outdoor lighting fixtures that are designed to point the light toward the ground. Shielded lights do not only reduce light pollution by preventing light to travel above, it also reduce glare and provides better vision at night.<\/p>\n Another way to have dark sky lighting is to choose lights that have timers, dimmers, and sensors. These features reduce light waste by turning it on only when it is needed. This is ideal because it also helps reduce energy waste and can also lower your energy bills.<\/p>\n Another way to have dark sky lighting is to choose LEDs or Light Emitting Diodes<\/a>. They are more environmentally friendly as compared to other types of lighting because they are energy efficient. As a result, it lowers energy waste.<\/p>\n Parrot175 shared the video below on YouTube. It is a documentary of dark sky lighting.
