How to choose LED bulbs?
First briefly about the disadvantages of saving tubular lamps.
Apart from environmental (intensive manufacturing, mercury content), mainly produce flashing light on its harmfulness to human body, there are many studies that are constantly spochybňovány.
It’s hard to explain to the elderly that produce very annoying high-frequency noise. Sound spectrum energy saving lamps, most people do not hear or perceive. There are, but also those who hear the annoying “whiz.” Another criterion is the greater consumption and current and decreasing luminosity. Often saving lamp tube type not live these hours, or the number of switching shown on the packaging. In contrast, LED energy-saving bulbs have many advantages which we summarize in the following points:
LED bulbs consump less energy
Whereas conventional energy-saving bulbs have been favorable compared to fiber consumption light bulbs, this is not an essential criterion. Yet it can properly selected according to manufacturers and suppliers calculate considerable financial savings.
Most worthwhile investment when switching from incandescent bulbs to LED bulbs. The next best option is to fit the LED light bulb in a new or renovated building. The principal advantage is:
LED bulbs shine even throughout the life
Here it is advisable to test in practice the use of LED light bulbs at the desk or PC. After several hours of sitting at work or on the book, you’ll know the difference. Your eyes are less tired. Compared to classical saving bulb flashing again get into the feeling that you had when using halogen bulbs or conventional fiber.
LED bulbs can also replace all tubular bulbs
Successfully can the LED technology used in some lamps, a whole range of tubular fluorescent lamps, the collagen, reflectors and photo flashes. On the market are LED bulbs H7, H8, sufitky, LED bulbs for tail lights of cars. It is necessary to warn customers against buying these nehomologovaných LED bulbs which are not approved for motor vehicles traveling on public roads. Superbly such compensation in the form of LED bulbs fit into the interior of vehicles such as different lighting or signaling elements where it is still used the vehicle manufacturer.
On the packaging we can look up information about what your old bulbs equivalent new product is responsible, but in practice this procedure did not work.
Let us follow the lumens, the parameter of light intensity. One must remember what values correspond to a 60W incandescent bulbs.
If we keep this process at home then we will not be embarrassed, because LED bulb does not light so far, he shone like the original, classic. Suitable equivalents to this value will be in the majority of the LED lamps 72 corresponds to about Wat bulb. Thus, if the manufacturer gave truthful information. See below:
Ledbulbbay Lumen light intensity incandescent bulbs 60W value corresponds 800L light intensity incandescent bulbs 100W value corresponds 1100L Another value is the “feels-like temperature of light” All types of LED bulbs can be purchased according to the manufacturers mostly in color cool white (about 6500K) or warm white (about 3000K) . It is good to feel and suitability warm yellow or cool white test on two samples of LED bulbs. Cool bluish tinge of some LED bulbs is not suitable for a longer stay and lighting at work. Conversely find application for example in outdoor lighting. The last parameter in the selection should be an indication of consumption Watts. It’s an important figure but it should not be the first or even the only parameter selection. Totally “out of place” is to follow the number of LEDs. More tell their technical sophistication. Conventional LEDs already known from electrical outlets Tesla-deployment to the lamp base will be the first attempt to manufacture energy-saving LED bulbs, but the market is no longer justified. Yet it is abundantly found in many a hypper Market.
