When you go to the store to buy a new bulb is faced with the need to decide what type of lamp to choose. There are several types of bulbs, and each has its advantages and disadvantages, but first everyone likes it – how will save your selection.
In Bulgaria and throughout the European Union, production of ordinary incandescent bulbs already in the past. However, they are still found in stores and mass people here are not aware of how much electricity could save if you opt for this type of bulb. Let’s look at the two most widespread species that are found in stores lighting.
When choosing LED light bulbs, it is necessary to compare the data with a luminous flux (lumens number) instead of watts. The more lumens, the more light LED bulb gives. Sometimes you come across a seller who sell LED bulbs obsolete technology, which have a higher consumption (more watts), yet fewer lights (less lumens) than new technology. The customer then has the false impression that buys more powerful bulb. But actually buys something that shines less and consume more power.
Some dealers say luminance LED bulbs compared with an ordinary light bulb. This information is very important, but in many cases it is mildly distorted. It is good to check on him just over a unit of luminous flux – lumen (lm). Ordinary bulb of 25W is 220-230 lumens, 40W has 410 to 430 lumens, 60W is 700-750 lumens. If you would anyone claim that the LED lamp shines as an ordinary 40W light bulb, yet has 300 lumens, he is lying! Equivalent performance LED lamps over incandescent bulbs can easily check the following table:
