You'll find that you have some view if the light. but you may not know all of them.

general light - provides the overall brightness for your lighting of room. It's essential for daily life as it simply enables us to see. Dimmer controls give flexibility to general lighting by allowing us to create different levels of general light, as opposed to just on or off. such as fluorescent lighting and incandescent lamps. Fluorescent lamps includs Compact fluorescent lamps (CFLs) and Fluorescent tube and circline lamps which use 25%–35% of the energy used by incandescent lamps to provide the same amount of illumination. They general last about 10 times longer just about7,000–24,000 hours.

The light produced by a fluorescent tube is s a gas-discharge lamp that uses electricity to excite mercury vapor. The excited mercury atoms produce short-wave ultraviolet light that then causes a phosphor to fluoresce, producing visible light.

Electronic ballasts outperform standard and improved electromagnetic ballasts by operating at a very high frequency that eliminates flicker and noise. Electronic ballasts also are more energy-efficient. Special ballasts are needed to allow dimming of fluorescent lamps.

Task lighting - used for a specific purpose, such as a light on your desk for reading ,flashlight,or lamp next to your bed. Task lights general provide a strong localized light. They should be positioned carefully to avoid casting shadows over a working area and to avoid causing glare to make the vision more clear.

Accent Lighting -is used to highlight objects and add depth and dimension to an environment.to create a focal point within a room by highlighting a particular item or feature Recessed adjustable fixtures, track lights, portable uplights and directional landscape lights are all in this category.

Ambient-is gentle fill light. It softens shadows on people's faces and fills the volume of a space with a warm glow, as from a roaring fire. Levels of ambient light are most frequently considered relative to additional lighting used as fill light, in which case the ambient light is normally treated as the key light. In some cases, ambient light may be used as a fill, in which case additional lighting provides the stronger light source, for example in bounce flash photography. The relative intensity of ambient light and fill light is known as the lighting ratio, an important factor in calculating contrast in the finished image.

led lights- is an electronic light source. Luminescence from an electrically stimulated crystal had been observed as early as 1907. The LED was introduced as a practical electronic component in 1962. compareed with the general light,led lamp is more Efficiency,LEDs produce more light per watt than incandescent bulbs,and more color provied ,LEDs can emit light of an intended color without the use of color filters that traditional lighting methods require. This is more efficient and can lower initial costs. About 20% of the average household's electric bill goes toward lighting cost, the U.S. Department of Energy estimates, and CFLs and potentially LEDs can help reduce that energy usage. To produce the same light as a 60-watt incandescent bulb, a CFL uses less than 25% of the electricity and an LED bulb potentially as little as 10%.
