LED lamps provide good coverage of areas of approximately 15 m².It turns out that for any of the rooms in the dwelling of a typical layout a 100-watt bulb is enough. Let's see what its LED-analogue is.
Marking
- The letter "E" is a socle class, that is, this sample is mounted by screwing it into the socket.
- "27" - thread characteristic( diameter, pitch).In this case, it is understood that such a lamp is for a traditional cartridge, which is used in most lighting fixtures( chandeliers, wall and street lamps and a number of others).
Specifications
Let's dwell only on the main ones that are interesting( and understandable) to the ordinary buyer.
Power
In this case, we need exactly 100 watts. The designations of LED products are indicated by the European standard. Without going into details, it is worth noting that "translation" is easy to do if you apply a factor of 6( this is the average value).
There can be no exact translation. Why?
Firstly, practice shows that not all LED-devices actually shine with such brightness, which should be based on the power declared by the manufacturer. And this is mainly characterized by Chinese products. For example, a lamp is purchased for 16W, and it shines at 75 watts.
Secondly, in part, depending on the version, the light flux is "eaten up" by the balloon( its matte coating).
Third, from what calculation is this value indicated on the package, with or without a bulb?
Color temperature
This parameter is indicated by numbers followed by the letter "K".In fact, this is a shade that gives a certain specificity of room lighting.
- If you need to choose the most accurate analogue of the usual incandescent lamps( yellowish light), then you should focus on the indicator of 2,700 K.
- Fans of "warm" white light should purchase samples for 2 800 - 3 200.
- Up to 5 000 K - usual daylight.
- More than 5,000 - white, but "cold".For residential premises is not recommended, as the constant presence in such a room in some people causes internal discomfort.
When choosing an LED lamp, you should consider in which room it will be installed. Many finishing materials( for example, tiles) reflect light very well. If the tile is colored, it is not known what effect will be achieved with the help of the LED-product. White fluorescent lamps are considered neutral.
Radiator
It can be ceramic or plastic. But in any case, somewhere should be viewed metal. Only it provides high-quality removal of heat from the balloon. Without this, the lamp will not last long, especially if it is installed in a living room - overheating( and failure) is ensured.
Practical tips
- Buy LED-device only in the store, and not from the tray in the market. And immediately check not only for serviceability, but also for the intensity of the glow.
- Often found information that the analogue of "hundred" are LED lamps for 10W( 800 lumens).This is too much "stretch", because given the inevitable losses, it can not completely replace the traditional one by 100 watts.
- Do not blindly trust the seller's recommendations. Firstly, very few of them are really professional. Such people make big money in a different way. Secondly, the personal interest in the volume of sales forces to dissemble even the most shy.
