LED lighting
A LED lighting is a light-emitting diode (LED) product that is assembled into a lamp (or light bulb) for use in lighting fixtures. LED lamps have a lifespan and electrical efficiency that is several times better than incandescent lamps (an electric light which produces light with a filament wire heated to a high temperature by an electric current passing through it, until it glows), and significantly better than most florescent lamps, with some chips able to emit more than 100 lumens per watt.
Like incandescent lamps and unlike most fluorescent lamps (e.g. tubes and CFL), LED lights come to full brightness without need for a warm-up time; the life of fluorescent lighting is also reduced by frequent switching on and off. Initial cost of LED is usually higher. Degradation of LED dye and packaging materials reduces light output to some extent over time.
- Florescent lighting
A florescent lighting is a low pressure mercury-vapor gas-discharge lamp (lamps that uses an electric arc through vaporized mercury to produce light) that uses florescence to produce visible light. An electric current in the gas excites mercury vapor which produces short-wave ultraviolet light that then causes a phosphor coating on the inside of the bulb to fluoresce, producing visible light. A fluorescent lamp converts electrical energy into useful light much more efficiently than incandescent lamps. The luminous efficacy of a fluorescent light bulb can exceed 100 lumens per watt, several times the efficacy of an incandescent bulb with comparable light output.
- Landscape lighting
Landscape lighting, or garden lighting, refers to the use of outdoor illumination of private gardens and public landscapes; for the enhancement and purposes of safety, nighttime aesthetics, accessibility, security, recreation and sports, and social and event uses.
With the combination of energy costs from energy demands, increasing availability of sustainable design methods, global warming considerations, and aesthetic and safety concerns in garden and landscape design the methods and equipment of outdoor illumination have been evolving. The increasing use of solar power, low voltage fixtures, energy efficient lamp bulbs-xenon bulbs-fiber optics, and creative lighting design are examples of innovation in the field.
- Under cabinet lighting
Under-cabinet lighting is typically added under a cabinet, shelf, or similar surface in order to produce localized lighting on a work surface. Under-cabinet lighting can also double as a night light. There are three types of under-cabinet lighting available for residential use in the USA: incandescent, fluorescent, or LED. The type of lamp dictates the lamp’s style and performance, such as amount of lighting it emits, the light’s color, the life of the lamp, and energy use.
+ Incandescent lamps are easily found and are inexpensive to buy and are easy to replace. However, they have the shortest life and use the most energy.
+ Fluorescent lamps have good light color, color rendering, turn on instantly, and do not flicker. They have high efficacy, long life, and bright, uniform lighting, However, some fluorescent fixture designs are not small or narrow enough to be concealed without modifying cabinet trip molding.
+ LEDs can last longer than 10 years and do not typically burn out. However, LEDs generate heat and are susceptible to high temperatures.- Security lighting
Some examples of security lighting include floodlights and low pressure sodium vapor lights. Most lights intended to be left on all night are high-intensity discharge lamps as these have good energy efficiency, thus reducing the cost of running a lamp for such long periods.Other lights may be activated by sensors such as passive infrared sensors (PIRs), turning on only when a person (or other mammal) approaches. PIR activated lamps will usually be incandescent bulbs so that they can activate instantly; energy saving is less important since they will not be on all the time. PIR sensor activation can increase both the deterrent effect (since the intruder knows that he has been detected) and the detection effect (since a person will be attracted to the sudden increase in light). Some PIR units can be set up to sound a chime as well as turn on the light. Most modern units have a photocell so that they only turn on when it is dark.
