From the school physics course, it is known: the intensity of light is measured in lumens. The problem, however, is that the lamp packaging usually only lists the wattage in watts.
This is interesting: weak light can cause mental disorders, building codes state: the average illumination of an apartment should not be lower than 150 lumens per square meter.
Choose LED bulbs
LED bulbs are the most expensive but last the longest.
The second problem is which lamp to choose. Indeed, in every store, there are a great many of them.
Today there are three main types of lamps:
- Incandescent lamps
- Luminescent or halogen – they are also called energy-saving
Pros: they cost no more than 20-30 rubles.
Cons: rarely work for more than one year. Moreover, these devices get very hot and can suddenly burst.
They cost more; the price can go up to one hundred rubles.
Pros: they serve three or even six times longer than usual.
Cons: an inert gas is pumped into the bulb of this lamp, which may contain mercury vapor. This means that the used lamp cannot be thrown into a regular waste container; such devices are collected in special containers.
Pros: the period of their work can exceed ten years. They do not heat up, and it is not scary to dispose of them in a container with solid waste.
Cons: the most expensive, from a hundred rubles and more.
Match the light for each room
It is better to choose warm light for the bedroom.
When choosing a light bulb, you should pay attention not only to its type and cost but also to such an indicator as to the “temperature of light.”
– You have probably noticed that some lamps emit colder, white light or warmer, yellow light. On the packaging of modern lamps, you can find the inscriptions: warm, neutral, or cold. This is how manufacturers show us what shade the device will shine with.
Please note: for the bedroom and nursery, he recommends choosing lamps with the inscription “warm.” This creates a cozy atmosphere, and the details of the interior acquire a soothing “blurred” contours. But in the living room, hallway and bathroom, you can use a harder “cold” light. Small objects are clearly visible in their bright colors; it is convenient to read, shave, and do needlework.
