Accent light: Such light is typically four times the intensity of an area's general (ambient) light and focuses attention on a specific object or room fixture. Quite often, halogen lights are used to provide a bright-white glow to an object. In some cases, the accent light can be equipped with a focusing lens in order to target a specific feature of a fixture or object. Display light: This light is typically of low voltage and is used in the display of small keepsakes, figurines, dinnerware, etc. In this case, xenon or halogen lights which range from 3W to 20W are typically used.
The proper name for color temperature is The Correlated Color Temperature (CCT). The CCT is described in degrees Kelvin (starting at absolute zero). It is backwards in a way, because when a color of a light source has a high temperature associated with it, it is considered to be a cool color, and if it has a low temperature it is a warm color. Lighting sources with a CCT rating below 3200 K are usually considered "warm", while those with a CCT above 4000 K are usually considered "cool" in appearance. Using a light with a high Correlated Color Temperature will give a greater perception of brightness in the space than lower ones. When calculating a color temperature (CCT) we take the light we are looking at, and compare it to a Blackbody standard base line color model that has radiant power at all wavelengths of light, and where our color falls according to the base model will tell us what our color temperature is. Even at a given Correlated Color Temperature, color can vary. To avoid such variation, the EPA recommends you purchase bulbs from the same manufacturer at the same time. The color temperature rating is listed on the product packaging.
The small size, long life and cool operation of the LED lends itself very well to boat lighting. Since they can operate for several years, run cool, and are very small in size, LEDs can be fully sealed or potted within a housing, making them impervious to water and air and thus extremely resistant to corrosion. Additionally, the solid state design of an LED navigation light makes it extremely durable. An LED equipped navigation light can withstand abuse and conditions that would normally make short work of an incandescent navigation light. Vibrations, pounding waves, rain squalls, and even minor impacts with docks will be shrugged off by quality made LED lights. About the best that can be expected from an incandescent nav light under those conditions is an expectation of servicing and replacement on a regular basis.
