Commercial lighting encompasses a lot of different types of lighting. From high bays to low bays, wall packs to flood lights, ceiling fixtures,moncler outlet, garden fixtures, barn lights and more,moncler outlet. Commercial lights cover all lighting fixtures and types that are used for anything other than residential lighting applications.

Before delving into the market of commercial lighting, you should make sure you are aware of some of the common terms that are to be found there. Let's first talk about candlepower. Candlepower refers to the brightness of the light. It is a measure of brightness that is adjusted to the select sensitivity of the human eye.
CRI stands for Color Rendering Index. This is an important factor that determines how surrounding colors will look when bathed in the light bulb's light.
Light is the frequencies of radiation given off by the sun that we are able to pick up with our eyes. An example of radiation that we cannot see with our eyes is ultraviolet and infared radiation.

The light bulb refers to the light source, which is contained within the shaped glass. The lamp is the light bulb and all of the hardware that assists with mounting,rolex submariner replica, positioning and framing the light bulb. However, it should be noted that in some industries,louis vuitton outlet, the light bulb is referred to as a lamp, and the assembly that contains it is called a fixture,timberland boots.

Lumens is a term that is often used but sometimes misunderstood. Let's talk about the human eye for a moment,moncler. The eye is more sensitive to some colors than it is to others. Lumens are a measurement of light, in which the amount of radiation that is present is taken into account and then adjusted to the human eye's selectiveness. A good example is having a room illuminated by an ultraviolet light,www.moncleroutletsky.com. Because we cannot see ultraviolet rays, the lumens measurement would be zero.

Fluorescent lighting is a very popular choice in commercial lighting, because they are incredibly efficient. So while they may be a little more expensive to initially purchase, they make up for the added expense by saving on energy: they use around 80 lumens per watt, which is a big difference from incandescent lights, which often use only 10 to 12 lumens per watt. Better still, fluorescent commercial lighting can have a lifespan of up to 30,000 hours. This number has doubled since only fifteen years ago! While these are definite advantages, some of the disadvantages to using this type of commercial lighting include the large size of the bulbs and lamps, and the higher cost of this type of lighting.
