In the olden days, if shelters used fire as lighting, even if it was in the form of a candle to a torch, you can now enjoy the ease of use of the optical technology invented by Thomas Alpha Edison. ..
In fact, with the evolution of technology, lamps come in a wide variety of technologies, shapes, wattages and more. Of course, the existence of a variety of lighting options aims to maximize all the space in the home, from the living room to the bedroom. However, many people are confused because there are many light options.
So what do you need to pay attention to when choosing a lamp and how can you determine the right light for your home? Check out the description in this article!
Know in advance what types of lights you can use
Currently, there are three types of lamps that are commonly used. Three types of lamps are TL lamps (Fluorescent light), lead (Light emitting diode), And halogen lamps. So what's the difference between these three types of lights?
1. TL lamp (Fluorescent lamp).
TL lamps are also known as pendant lamps, including economically priced lamps and are widely used by people.This type of lamp utilizes NEON gas and coating fluorescence As a luminous body when an electric current is passed. This will take some time for this lamp to fully illuminate. Compared to traditional incandescent lamps, this type of lamp is four times more energy efficient.
2. LED light (Light emitting diode).
Compared to common incandescent lamps, LED lamps can save up to 90% energy. This makes LED lamps the most energy efficient lamps available today. LED lamps also have a long life, reaching 25 years. Not surprisingly, the price is high, but this one lamp is still one of the favorite types of residential lamps. However, keep in mind that LED lights need to be carefully cared for to maintain their durability.
3. Halogen lamp
Halogen lamps work like incandescent lamps, that is, with filamentous filaments. This makes the light quality and color of halogen lamps similar to incandescent lamps. This lamp was created to solve the size problem of relatively large incandescent lamps.This type of light bulb, which is relatively expensive, is usually used as a decorative lamp Desk lamp Or spotlight.
Understand the wattage of the lamp and how to choose the right wattage lamp
Watts are the amount of energy used by a lamp or light bulb. If you choose a low wattage lamp, you can see that the light produced is not brighter than a high wattage lamp. Typically, 1 watt lamp produces 75 lumens.. The lumen itself is an important lighting unit used to calculate the lighting requirements of a room.
Then how do you make sure you are using the right lighting in your room for maximum lighting?
1. Know the lighting standards for each room in your home
First of all, you need to know the standard lighting requirements of the room. Simply put, the lighting standards for a room based on light requirements are:
terrace, Lighting standards: 60 lux
living room, Lighting standards: 120-150 lux
dining room, Lighting standards: 120-250 lux
Workspace, Lighting standards: 120-250 lux
bedroom, Lighting standards: 120-250 lux
BATHROOM, Lighting standards: 250 lux
kitchen, Lighting standards: 250 lux
garage, Lighting standards: 60 lux
2. Calculation of room watt lamp requirements
Once you know the lighting standards, you can start calculating the required wattage and number of lights. However, to do so, be sure to measure the size of the space as well. Once all the data is complete, you can calculate the data using the following formula:
N = E x L x W / ØxLLFxCu xn
information:
N = number of light spots
E = strong lighting (lux), standard home or apartment 100lux --250lux
L = Room length in meters (length)
W = Room width (width) (in meters).
Ø = Total lamp brightness in lumens
LLF = (light loss factor) or light loss or loss factor. Values are typically 0.7-0.8.
Cu = (utilization rate)
n = number of lights at 1 point
3. An example of calculating the need for room lighting
For clarity, let's practice this formula in a case study. Suppose you have a dining room that is 5 meters long and 4 meters wide. How many TL light points do I need to maximize the lighting in my dining room to use a 40 watt TL lamp?
According to the standards we already know, the lighting standards for dining rooms range from 120 to 250 lux. As an example, take the median value of 200 lux. Then you can see that E = 200 lux.
Since the bulb used is a 40 watt TL lamp, we can see that the lumen value or Ø of the lamp is 40 watts x 75 lumens and Ø = 3000 lumens.

To find the coefficient or CU value (Utilization factor), You can use the standard coefficients of direct lighting in brightly colored spaces. This is in the range of 50-65%. You can use the minimum value of 50% or 0.5 for this case study.
The last component is Light loss coefficient (LLF) This is generally 0.7-0.8. The LLF itself is affected by various factors such as the cleanliness of the light source, the type of lamp shade, and the shrinkage of light from the lamp surface. You can use the minimum value of 0.7 for this case study.
Before calculating, note that the value of (n) is 1 because each ramp point uses only one TL ramp.
Now let's apply all the data to the calculation
N = E x L x W / ØxLLFxCu xn
N = 200 LUX x 5 meters x 4 meters / 3000 lumens x 0.7 x 0.5 x 1
N = 4000/1050
N = 3,8
Based on these calculations, it is known in the dining room
It requires 3.8 light points, but of course it is rounded up to 4 TL lamps at 4 different points. Therefore, the wattage required for a dining room is 4 x 40 watts. 160 watts
Choosing the right lamp shape
After knowing the type and wattage of the lamp, another thing that needs to be considered but is considered trivial is the shape of the bulb. The shape of the light bulb is important because it affects the distribution of the light emitted by the light bulb.
Of the different types of light bulb shapes, the rounder the light bulb, the more uniform the light distribution. However, attention should also be paid to the visual presence of the light bulb shape in the room. Activity and space requirements also influence the choice of bulb.
In an activity-centric space, you don't need a fully diffused light bulb.Spiral type or lamp stick We may be able to meet your needs. Shades can be added to the lamp to focus more light on the lamp.
