LED or energy-saving lamps what you should buy

Now, going to a specialized electrical shop, just look at first. And general consumer can be quite a logical question, which is better to buy a home: energy-saving or LED bulbs. In this article I will make a comparison of the lamps according to various indicators and draw conclusions about their benefits.

How much energy they consume

We begin our comparison with the most important indicator, because we are with you decided to save, and this means that we need the most effective option.

On average, the fluorescent lamps consume only 20% of the power consumption of standard incandescent light bulbs.

LED lamps consume 10% of the standard consumption of incandescent lamps.

And it turns out that if we compare our competitors, the LED light turns effectively doubled with identical brightness glow.

Light flow

In terms of light output of fluorescent lighting products can not boast of stability and quality. They are not quite correct transmit spectrum of different shades of light. In this regard, the LED is the clear leader in terms of reliability and quality.

Here is the comparative table of the considered samples:

Heating during operation

The normal operating temperature of the gas discharge bulb is a figure of 50 to 60 degrees Celsius. This temperature is not able to burn the skin or trigger ignition, but in the case of failure of the lamp control unit, the temperature may increase by several orders of magnitude.

LED heats up even less due to the use of semiconductor technology. At first glance it seems that there diodes win, but in fact the temperature of the discharge lamp does not go beyond permissible limits and therefore they can be used in absolutely any fixtures. So on this indicator draw.

health safety

In the bulb of a discharge lamp is present up to 5 milligrams of mercury, which automatically makes these lamps are quite dangerous in case, if the bulb is broken. It is because of the presence of mercury can not be a failed energy-saving lamp just throw in the trash. It must be attributed to a special collection point.

LED bulb is completely safe and if onaya broken beyond repair, you will easily be able to throw it with other waste in the trash.

flicker

The cheapest "enegrosberegaykah", which does not use a quality starter knob, a glimmer of light is carried out with the power frequency. And let the human eye does not notice this effect, but it is not absolutely positively can affect the general psycho-physical state of the body. The expensive models, this problem of course not.

But in the LED lamps, even the cheapest samples, such a problem does not exist.

efficiency

The ratio of the luminous flux outputted to the consumed power is efficiency. Discharge lamps, of course, more efficient than conventional light bulbs Illich, but also their efficiency rate varies around 30% in the numbers.

LED lamps also give in terms of efficiency index 80%, which means their efficiency in this regard.

Life time

This option is also very important and often very controversial. If you believe these statements of producers, the LEDs are ready to serve up to 50 000 hours, and energy-saving lamps burn through up to 15 000 hours.

It seems to be a difference in the face, but this only applies to high-quality products from trusted manufacturers.

But due to the fact that the diode, there is such a thing as the aging of the crystal, in the Chinese light bulbs, these should just flooded our counters, manufacturers deliberately overstate the current flowing through the diode in order to increase the light output at the same time not worrying about withdrawal heat. Low-quality diode lamps burn out very often. And it may seem that the LED products are very poor quality. In order not to be disappointed in it choose the right products.

Working in extreme conditions

Inclusion of gas-discharge light bulb is as follows: the current flowing in a spiral, heats the surrounding mercury vapor discharge the same start to emit ultraviolet rays. Thanks to them, begins to glow phosphor distributed over the walls of the flask.

Therefore, at normal ambient temperature of the discharge lamp is switched on with a delay of 1 second (the time required to heat the gas). If the temperature outside is low or has a negative value, the volatility of mercury gas is drastically reduced, and requires much more time for heating thereof. When severe frosts these bulbs generally can not catch fire.

Again, the diodes have a very wide range of temperatures and the lack of such a problem.

Price

And here we come to the most important criterion, according to which, despite all the obvious advantages and disadvantages, will be guided by the buyer. It should be recognized that quality diode lamps more expensive energy-saving.

conclusions

As you can see, almost all parameters LED bulbs outperform "energoesberegaek", but the latter still has a trump card, namely the price. But, despite the higher cost, I would recommend it to acquire quality LED lighting devices, as in the long term they will be still more profitable to all others. Thanks for attention.
