Incandescent lamp, with its cheap price has a drawback, it comes from only 5% of light the rest is heat. Accordingly, this lamp consumes the electricity for heat.
New generation lamps, consuming electricity produces 90% of the light.
Definition of fluorescent light
Fluorescent lamp, also called, fluorescent lighting, are glass tubes, sealed at both ends, coated inside with a thin layer of phosphor. The lamp is filled with inert gas – argon at very low pressure. Inside the lamp holds a small amount of mercury, which when heated is converted into mercury vapor.
Fluorescent lamps are a type of incandescent lamp, but with a few improvements. The principle of the glow in them is based on heating a tungsten element, an electric discharge in mixtures of inert gases and mercury vapor contained in a glass bulb, causing radiation in the ultraviolet spectrum (i.e. invisible to humans). This radiation is absorbed by a special composition, which is coated inside the bulb, which causes the glow that the human eye can perceive. The composition, which causes the luminescence is called a phosphor, is a mixture of different substances based on phosphorus. It has various colors, not only white.
The service life of energy-saving lamps 15000 hours, which is 15 times higher than ordinary incandescent lamp, energy consumption is 90% less than conventional lamps.
This lamp shine is 5 times brighter than normal because the lamp power of 20 watts gives as much light as 100 watt incandescent lamp.
But is this the lamp 5 times more expensive. Even so, it will pay for itself quickly due to the low energy consumption and durability. If you put all the energy-saving lamps in the apartment, on the electricity bill you will see how much less the expense.
Energy saving lamps emit much less heat and could, therefore, not afraid to put in nightlights and sconces. Because these lamps always write the maximum power of filament lamp, if you put in sconces more powerful bulb to get more light, the lamp will not withstand overheating and melted. Including the wires are not designed for more powerful bulb.
The size of energy-saving lamps and more when choosing it is necessary to consider whether it will fit in your lamp. There are two main forms of energy-saving lamps “U” shaped and spiral, they Shine the same, but the second one is a little more expensive because the manufacturing process is more complicated.
Light color energy-saving lamps. The temperature of the glow-2700K soft white light. 4200К daylight. 6400К cool white light. The higher the temperature of the illumination light closer to blue, to red below. Therefore before purchase it is better to determine what color of light is more pleasant for you.
Power energy-saving lamps. Lamps are from 3 and up to 85 watts given the fact that energy-saving lamps illuminate 5 times more powerful, where you put 100 watt standard bulb have put energy saving 20 watts.
When you buy energy-saving lamps pay attention to the box, it says the settings. For example: lamp ESS-02A 15W E14 6400K – means that we bulb 15 watt, with a small E14 cap and a color temperature of 6400К that will give a cool white glow.
Incandescent lamp — a light source which emits the luminous flux as a result of the heat filament made of metal (tungsten).
The filament inside a glass vessel filled with inert gas (krypton, nitrogen, argon). The principle of the incandescent lamp is based on the phenomenon of heating of the conductor during the passage through it of an electric current. The tungsten filament when connected to the power source heated to a high temperature, resulting in emits light. The luminous flux emitted by the filament, close to natural daylight, therefore, does not cause discomfort during prolonged use.
