Even at the household level for a long time
did not meet the traditional incandescent lamp. They are replaced by
fluorescent or LED counterparts that surpass outdated light sources for a
variety of indicators. In Russia, the process of updating light fixtures began
only a few years ago, but still cannot talk about an effort to give users the
usual devices. In part, this attitude can be justified, and the high cost of
more technologically advanced products, and spread rumors about their health
risks. But, as practice shows, in the aggregate performance of modern lighting
it is the best solution. It remains only to determine the order, what better
light - LED or energy-saving? Both appeared on the market relatively recently,
but today most consumers there is no clear understanding of the properties of
this product.
It depends on the brightness of the beam, but
also power consumption. The special features of LED devices include power
reduction effect on energy consumption. In such models, the figure has a
broader range, but in standard designs it is in the range from 4.5 to 15W. The
advantages possessed by the lamps for LED light bulbs (e.g. E27 LED Bulb 220V) can be attributed to the ability to control the light
beam settings with the expectation to minimize electricity consumption. The
brightness of the light is measured in lumens and the ratio of this figure with
the power can be called one of the most profitable in the Led-models. Thus, the
light bulb 15 W corresponds to the brightness of 136 lumens, and the models of
25 W - 249 lm.
Another essential characteristic - it is
light temperature measured in kelvins (K). LED models (e.g. 240V LED lamps)
are quite varied and in this parameter. For example, there are options to 3300
K, which provide the so-called warm light. The standard is considered an
indicator of 4000 K. It is a natural, or the light of day - the best option if
you want to provide coverage at home with the natural properties of the eye
perception. Less common "cold" light corresponds to the index of 5000
K. It is usually used in special cases, such as in the workplace.
