It is a continuous spectrum of an incandescent lamp

Which is better - an ordinary bulb or energy saving.

First of all, we note that the principle of operation of virtually all known lamps is similar - at the two electrodes is the thread on which an electric current is supplied and there is light.Only a standard incandescent bulb - glow emanates from the filament.The inner surface of the bulb "housekeeper" is covered with a thin layer of phosphor material, providing light by ultraviolet radiation generated by mercury vapor.

first light bulb Edison produced from coal filament of bamboo, and it burned for about 40 hours.In our century, this can not be surprised, and replace outdated come the new electric lights - power-saving and LED lamps.Like which one is better - a fair and urgent question for those who appreciate comfort and economy.

main advantages of energy-saving light bulbs:

• durability - a life of such bulbs is around 10 thousand hours of continuous operation as opposed to incandescent lamps, whose life - 1 thousand..hours.This means that if you turn on the lights on 50 hours a week (statistics), the housekeeper will last for 4-5 years, and replace the usual pass through a 4 - 5 months;
• luminous brightness of incandescent lamp depends on the properties of the filaments and the magnitude of the applied voltage, and the "housekeeper" shines through phosphor pleasant soft light;
• efficiency (efficiency): incandescent lamps it is not more than 5%, and the remaining 95% goes to heating the bulb.Housekeeper not have this drawback;
• energy savings: thanks to his property is not heated during the energy-saving emission spends on lighting electrician unlike conventional lamps.

Argued that the beam of light energy-efficient light bulbs eyes hurt.This is because it was once used in organizations daytime fluorescent light bulbs, which are required to include an electromagnetic actuator with a small frequency, and this influenced the surge of light.In today's high-quality housekeeper this starter with electromagnetic replaced by an electronic, and it practically does not pulsate, and the light from a lamp will not affect your vision.

Industry produces both small and large energy-saving lamps.Power from such lamps may reach up to 1000 watts.If you choose an energy-saving lamp, you should pay attention to its labeling, for example, on the lamp from the manufacturer «maxus» says: 13W E27 6400K, which means that it has a cool white light (6400K), the average diameter of the cap 27mm, and the power of such a lamp 13W.With regard to the light emitted is worth noting that there is a choice Mezhuyev warm white, daylight and cold.Experts do not recommend to buy housekeeper kitchen lighting the cold white light, as they may distort the kind of food.And it is not necessary to install "housekeeper" in places where light include brief (e.g., a restroom), instead of saving in this case are obtained even greater costs.In such a lamp ignition requires a little more starting current than rated, but if you turn it on for a long time, it does not consume a lot of electricity.

should be attributed to shortcomings of housekeepers:

• primarily the cost, but there are also quite high-quality Chinese variants;
• content in a flask of mercury droplets.Mercury is a poison, and therefore restore a lamp, without compromising the health, can not be.

about the pros and cons of energy-saving lamps can talk for a long time.Everyone has to decide for themselves the question.But scientific progress does not stand still, and the replacement of the housekeeper had already come LED bulbs, but they are ten times more expensive.
