About thirty percent of their life almost every person spends in the workplace and quality quality lighting is very important to him. After all, the work becomes much easier and more enjoyable when the environment promotes it.

In this article we solve the issue of office lighting with led lamps. Try as informative as possible to answer the most popular questions. Give your tips and recommendations on how to save money and to choose really high-quality product that will meet all your requirements.


To properly arrange the lighting in the room must know the rules of the level of light in the room. Based on the rules you can find out how many lamps you need to install how to install them. Knowing the quantity of lighting points, you can roughly calculate the amount in which you all will be fine.

Calculate the number of luminaires is more accurate if the room has a simple square or rectangle. If the form is a custom form then you should divide it into areas of simple shapes and calculate them separately for greater accuracy.

It is customary to measure the level of illumination unit Lux or abbreviated as LK. A luminous flux which can give out light bulb is measured in Lumens abbreviated as LM.

The calculation consists of several parts

The whole calculation is concluded in a simple formula LM=A B P.

Where As the normal lighting for the premises, the value is taken from the table №1.B the area of the premises or area for which calculation is done. With the correction factor for altitude. For standard premises with height up to 2.7 m value is equal to one. At a height of 2.7-3 figure will be 1.2 at a height of 3 to 3.5 meters the value will be 1.5 when ceiling height is 3.5-4.5, the value will be equal to two.

Table 1 Knowing the type of area and the height of the walls, you can proceed to calculations. Let's take for example the office area of 150 square meters and a height of 2.7 meters. For office General lighting 300 LX norm. At the height of the walls of 2.7 meter correction factor will be 1.2. Substitute all values into the formula LM=150 1.2 300=54000 LM. Now look in the table No. 2.

Table No. 2 Using the bulb at 12 Volts which can emit 1100 Lumens we need 54000 divided by the amount of luminous flux of the lamp. It turns out 540001100=49.09 pieces. You can round up to 50 pieces. As you can see, everything is very simple and count all this will not be easy for you.

However, lamps with high power will not be able to provide uniformity of lighting. Better to use more ceiling lamps so they can be placed evenly on the ceiling. Recessed lights have a small-angle scattering therefore, the increase in number compensates for this deficiency.

Led office lighting can be divided into four groups

Let's look more closely describe each of these groups. Let's start with the purpose of led lamps

There are false ceiling or recessed. Emit light vertically toward the floor. Typically used for General lighting throughout the room.
Outdoor often embedded but you can find the invoices but they are less convenient. Have a luminous flux is the same as the ceiling is only pointing up.

Types of lamps for office

Often this wall lamp invoice. The study of the ways light can be quite varied but most often light spreads on the surface of the walls of the hemisphere or in all directions at once.

Designer lamp can accommodate a combination of different fixtures and have a variety of functions including the ability to adjust the glow. Apply when the standard lamps are not suitable or when solving design tasks.

Classifying according to size and shape it is possible to allocate the following items

The method of installation is divided into two types, overhead and recessed. Each of them has their own good and designed to be installed in any part of the premises. Invoices are used as ceiling, walls and floor. Embedded in the main set the ceiling structure and the floor.

Using the overhead or flush led lights in large office buildings can save a substantial amount on electricity. Led lights use 50-70% less electricity than their outdated counterparts. To save on electricity you can add the lack of maintenance often services require big financial expenses. The life of the LEDs can be up to 10 times longer than fluorescent lamps.

To choose the right quality and the right led lamp for your office should know exactly how much you need bulbs what type of light they have to emit a method of mounting and the type of surface on which they are installed.
If you have a fairly large office to cover it in several heavy duty lamps will not work. It is better to use a large number of low power lamps which will emit light evenly over the entire area of the office.

For work areas it is better to install the led lamps with directional light. Overhead lights well will serve for illumination of passageways and billboards with ads or important information. For illumination of areas with low frequency of operation so it is better to use a low power overhead lamp.

When you select should pay particular attention to the dimensions of lamps as ceiling Armstrong bulb required a specific size. By purchasing a lamp more or less than the required size, you will spend money for nothing or will incur additional cost of installation of such devices.

As led office lighting is quite expensive many people will decide to save money and buy cheaper models but this way, you can come across many pitfalls. To reduce the price of led devices the manufacturers use materials of rather low quality namely LEDs themselves.

For example, LEDs are very sensitive to the environment they must be absolutely protected from dust and moisture in the air.

Due to the high degree of protection, they are not subject to any other influences. But using cheap materials for protection promotes rapid damage to the diode and deterioration of its work. Lamp with low price I often start to emit a lower light level after a certain period of time and very often this change is quite noticeable to the naked eye.

Branded products from well-known manufacturers can cost several times more expensive but their quality is much higher. They are of course as cheap models can lose their brightness, this change will be soon and imperceptibly to the human eye. In addition, there is guarantee which in most cases gives you 100% assurance that you will get a refund or will replace the product if it is defective.

For quality and comfortable lighting in the office should go to its arrangement with complete seriousness. You should carefully choose the type of lighting to calculate the number of required fixtures based on the required level of lighting for your specific room.

Consider what lighting is best to use the overhead or flush. And when choosing a manufacturer is to spend the extra money and choose the quality than to regret buying a cheap analogue which can be very low quality.
