LED luminaires are economical, last longer, emit even light, generate almost no heat, and are easy to install. When choosing such a luminaire, you should pay attention to the technical characteristics, think over how and where it will be mounted, whether the LED luminaire corresponds to the purpose of the room, and how well it goes with the design.
What to look for when choosing a lamp
There are 5 basic parameters to help you choose the right LED fixture for you.
1. Luminous flux power
The luminous flux power must correspond to the purpose of the room and its area. Illumination standards for different rooms are shown in the table:
It should be borne in mind that the norms are taken for ceilings with a height of 2.5-3 meters. If the height of the ceilings is greater, then the base value can be safely multiplied by 1.5-1.7 times.
Using the table, you can calculate the required number of LED lamps for the room. The technical passport usually indicates the value of the luminous flux of the product. For example, the luminous flux of a luminaire is 400 lumens. The number of luminaires is calculated using the formula:
(Room area X Required light level) / Luminous flux
For example, for a 12 m² bedroom you will need 6 LED lights: (12 m² x 200 lux) / 400 lumens = 6 pcs.
2. Color temperature
For residential premises, lamps with a color temperature of 2200-3000 Kelvin are suitable, they give a more comfortable, warm light, corresponding to incandescent lamps. Luminaires with a color temperature of 3400-4500 Kelvin have a brighter white light and are more suitable for commercial premises, i.e. offices. Luminaires with a color temperature of 6500K and above are intended only for technical rooms.
3. Type of LEDs
Most LED luminaires use two types of strips:
- SMD 3528 with a luminous flux of 4-5 lumens,
- SMD 5050 with a luminous flux of 10-14 lumens.
The brightness of the luminaire will depend on the type of LED.
4. Angle of light flux dispersion
There are lamps of diffused and directional light. Luminaires of diffused light are suitable for home, office, industrial and warehouse premises. For spotlighting (illumination of goods in a shop window, streets, and roads) – directional light.
5. Ra color rendering index
This figure should be 80 and above. It determines how natural an object looks to the human eye when illuminated by an LED light.
The main types of LED lamps
Recessed LED luminaires – recessed into ceilings or walls. The most common are square plasterboard ceiling fixtures (Armstrong) and round fixtures (fisheye).
Fun Fact: An old Armstrong office light on conventional lamps can be easily converted into an LED fixture using special conversion kits. The kit consists of LED strips, a power supply, and wires.
How to Choose a LED Ceiling Light
When choosing, you should take into account the type of ceiling on which the lamp is attached. How to Choose LED Stretch Ceiling Light? In this case, the following are suitable:
- suspended (attached with hooks to the main ceiling);
- waybills (attached using special bases, to which power is supplied);
- recessed (the principle of fastening is the same as for surface-mounted luminaires).
For suspended ceilings, choose special plasterboard suspended ceiling fixtures. They can be swivel or non-swivel.
At the stage of repairing and designing a suspended ceiling, you need to think about where you need to place the fixtures. After installation, it will be problematic to change the location of the wiring or pull a new one.
The following fixtures are used for the Armstrong ceiling:
- recessed (mounted instead of a plasterboard square),
- overhead (attached to the ceiling),
- universal (can be built in and fixed to the ceiling),
- suspended (mounted on hooks to the main ceiling).
Some features should be considered when choosing an LED luminaire for rooms with high humidity.
How to choose a LED bathroom light
The algorithm is as simple as in the case of choosing a luminaire for other areas of the apartment:
- The design of the luminaire is important, it must be closed to avoid contact with water.
- Consider the location of the lamp, preferably as far away from the water as possible.
- Use low voltage lamps.
Pay attention to the IP (International Protection) waterproof index. The diagram shows the recommended indicators depending on the proximity of the lamp to the water.
