Task lighting Task lighting is used to provide a localized light source for a specific tasks. Some popular task lighting sources include desk lamps, kitchen or bathroom pendants and lights in refrigerators and other appliances. The type of lighting is designed to be used only when the task is being performed. When it is not needed, it can be turned off to conserve energy and extend the life of the bulb. Lighting a small space to perform a specific task; reading, cooking, eating.
Lighting Technologies The traditional light source in the home is the incandescent bulb. Invented more than 100 years ago, this technology is reliable, but is quite inefficient, and bulbs have a short lifespan. Compact fluorescent bulbs are more efficient, and last much longer than other bulbs. These bulbs work with most types of indoor light fixtures, but are not very effective when used with dimmable fixtures.light fixtures The newest type of lighting technology used in the home is the LED bulb. These bulbs are highly efficient and long-lasting, and newer models can be used in dimming applications.
Incandescent Light Light bulb most people use. Burns about 700-1000 hours.
Fluorescent Lighting Lasts up to ten times longer than an incandescent bulb. Use less electricity and produce no damaging heat. Not as homey and comfortable.
Halogen Lighting Lamp is kept brighter than incandescent bulbs. Light is more similar to that of sunlight. Bulbs burn whiter than incandescent bulbs.
Tungsten-Halogen Lamps A type of incandescent lamp. Encloses the tungsten filament in a quartz capsule filled with halogen gas. Halogen gas combines with the vaporized tungsten and redeposits it on the filament. More efficient. Lasts longer (up to 6,000 hrs.)
LEDs-Light Emitting Diodes Lower energy consumption. Longer lifetime (50,000 to 100,000 hrs). Smaller size. Faster switching. Greater durability and reliability. Cycling. Dimming.
