What are the different types of bulb?

The light light is an electric lighting that uses extreme heat to produce artificial light. This type of bulb has been widely used for more than a century to light houses and whole cities. There are different types of bulb and each differ in the amount of energy desired and emitted. When the power switch is on in the room, the electric current flows inside the bulb and flows through the thin wire fiber inside. This fiber is often made of tungsten, which is metal resistant to high temperatures that causes bright lighting. The government is usually covered with a thin glass bulb that keeps oxygen outside and protects tungsten. They are made of special glass that retain the heat that Might is lost in standard bulbs. This allows tungsten to use less power when heating and usually gives the lamp a longer life. One disadvantage of halogen bulbs is that they are often more expensive than standard.

Light reflector is commonly used in the show show, for example on theater stages or film studios. These bulbs are easy to move or direct and light light on specific areas can shine. Spotlights is often used to highlight the exact place on the stage, while headlights and downloading produce lights of different intensities and sizes to fill space. These lights can be used inside and out.

Glow light can also include thermal lamps that require a lot of energy and are commonly used as a heat source. These lights are often installed on farms to keep the animals warm in winter. Farmers usually put them in chicken teams or houses where birds encourage to lay more eggs.

There are other types of modifications that can be made in bulbs for specific purposes. Lamp manufacturers sometimes consult a color spectrum to apply different shades to the bulbs. Most standard lamps emit bright light that often appears to be yellowthat and do not fit the whole room evenly. To repair this problem, the interior of some bulbs is covered with blue and green diffuse layer, which brightens light and allows it to illuminate more space. To reduce eye stress, bulbs are designed for reading or similar activities often larger than diameter and have a white inner coating that produces softer light.
