Instruction
1
Measure the area where you want to install lighting.
2
Number of lamps per 1 sqm of the area depends in the first place, from the power lamp. If the bulbs in the lamps have a capacity of about 35 watts, you need to install one lamp per 1.5 sq. m. There is a rule that distributes the lamps: each 1 sq. m. area shall be illuminated 20 watts.
3
If spotlights are to be installed as a Supplement to the main lighting, such as chandelier, it is possible to reduce their number or place in a specific zone for illumination.
4
The minimum distance between the point lights should be about 30 cm And the angle from wall to the lamp is about 20 cm.
Note
In stores you can find numerous types of spotlights. They differ in the direction of the flow of light and the type of dispersion. There are spotlights, equipped with a rotating mechanism, thanks to which you can easily adjust the light direction. You can also find lamps with lamp placed outside. They usually have an external canopy that allows to increase the angle of light leakage. These lamps will need less, as they are able to cover a more extensive area of premises.
Useful advice
Position the fixtures using various options. The most popular way is located in two or more rows of the perimeter of the ceiling. You can position lights in the shape of a circle.

When covering a square room take the advice of designers and position spotlights in the corners of an isosceles Pentagon.

For uniform illumination of the room use the chess position.

Advice 2: How to change a light bulb in a spot lamp

Anything eternal does not happen. So light bulbs have a service life and then burn out. And if the owner, and often the hostess, a good idea of how to change a light bulb in a conventional ceiling chandelier, if necessary, replace the bulb in a spot lamp often there is some confusion: what we need to do this otherwise.

Advice 4: How to calculate the lamp power

For proper illumination of rooms, corridors or free-standing object, such as aquarium, you need to determine the appropriate type of lamp: number, location and capacity of the installed lamps. There are a few rules, doing that, just to perform this task.
How to calculate the lamp power
You will need
  • roulette, sheet of paper, pen, calculator
Instruction
1
For the General calculation of the lamps use the following formula: P=pS/N, p –power, the specific lighting, measured in Watts per square meter (the average is 20 Watts per square meter), S is the area of the premises, for which this lamp is calculated in square meters and N is the number of lamps.
2
Example: calculate the room measure the length and width of the room. The results obtained (for example, 3.3 meters long and 4.5 meters wide) between multiply and get the area of this room (3,3 × 4,4 = 14,85 square meters). This figure multiply by 20 and divide by the expected number of bulbs in lamps. For example, take the 3 lamps on 2 lamps in each. In this case, 14,85 multiply by 20 and divide by 6 (3×2=6). Get the result, which means that in this case, you have 6 lamps at 49.5 Watts.
3
Can vary the wattage in each lamp, dividing the room into several zones with different lighting. The total power of all lamps in the room should not be less than 297 Watts.
4
In some cases it is necessary to take into account the specifics of the premises, which make the calculation of the total power of the installed lamps. In this case, do the calculation, substituting the value of the coefficient p in the table below:property Type|incandescent Lamp|Halogen lamp|fluorescent svyatetsky room..............30-85....................70-85....................15-22
Living room.....................15-35....................25-35....................7-10
Bedroom......................10-25....................15-17....................4-7
Corridor......................10-20....................10-13....................3-5
Kitchen........................15-40....................30-37....................6-10
Bathroom...............15-30....................22-27....................6-9
Storage room, garage..............12-15....................11-14....................3-5Здесь, to calculate, for example, lighting in the kitchen (area 3 meters square) with the use of fluorescent lamps, take the coefficient of p (average 9) from table, multiply by the kitchen area and if you will be trehrozhkovye lamp, divide by three: 9×3/3 = 9 Watts in each of the three installed in the lamp bulb.

Advice 5: How to calculate the amount of siding for wall cladding

In order to properly calculate the amount of siding for the cladding of walls, first you need to find out what criteria needs to be the choice of material. Only then is it possible to start the calculation.
How to calculate the amount of siding for wall cladding
Due to the ease of operation and affordable price, the lining is one of the most popular finishing materials. In addition, it is quite versatile, its applications are endless: clapboard sheathe as baths and balconies.

Calculate how much you will need siding for wall cladding, is quite simple. Knowing the area is easy to calculate how many slats you'll need. However, there is one caveat: the lining is sold in cubic yards, not in pieces or linear metres. Therefore, it is necessary to do some calculations.

Selection of quality material



To more precisely calculate how many slats you'll need, you need to choose a good sturdy strap. Should pay attention to the direction of the cut, it must coincide with the direction of growth of the tree. You also need to pay attention to the location of the annual rings. They must go beyond boards, this parameter directly affects the strength.

When choosing finishing material, every person, first of all, think about aesthetic appearance. To leather lining the surface looked decent, you need to choose straps with smooth edges, taking into account the humidity of wood, which must not exceed 17%. Otherwise, the Board can be fragile and break during processing. You should also pay attention to the valid for a given tree species the number of knots.

The correct lining will allow you not only to enjoy the beautiful decoration, but also to calculate, what quantity of material you need.

Calculate the amount of lining



In order to calculate the amount of lining required, you need to calculate the area, multiply this perimeter by the height and given the door and window openings. Next you need to calculate the area of one rack, by multiplying its length by the height, and knowing the thickness, it is possible to obtain the volume of one plank. To obtain the necessary number of strips, you need the area of the space divided by the area of one plank. And knowing the volume of one of the boards and number of boards, it is easy to calculate how many cubic metres of lining will be needed for decoration.

You should choose the lining, strap length which is a multiple of the height of the room, it will minimize waste. But in any case, the volume should be multiplied by 0.15, because no matter how you try to reduce waste, they will still be. 10-15% of the total volume is the norm, calculated for ideal performance.
