How to choose the right LED lamp?

Key parameters to consider when choosing a lamp.
High-quality lighting is the key to health and well-being. Light affects biorhythms: it promotes the production of hormones that are responsible for activity and performance during the day and relaxation in the evening.

In winter, when there is the shortage of natural light, you can regulate these processes using artificial lighting. During the day, turn on bright lamps to invigorate and work more efficiently. In the evening, on the contrary, dim the lights, creating a relaxing environment for rest and preparation for sleep.
Improper lighting can significantly reduce performance, make a person irritable, cause depression, insomnia, and other disorders. Therefore, it is so important to choose a lamp deliberately.
Power and luminous flux
Power is the amount of energy consumed by the lamp per hour, measured in watts. For indoor LED lamps, typically 3-12 watts.

Luminous flux (in lumens – lm) is a measure of the brightness of the lamp. With the same lamp wattage, the luminous flux may vary.

The optimal luminous flux for a workplace or reading (table lamp) is 500-700 lm.

One lamp with a luminous flux of 700 lm will be sufficient to light the surface of a dining table, situated up to 1-1.2 sq. M. below the lamp. We recommend hanging several lamps over a long table.

Decorative lighting (table lamps, wall lamps) - 400-600 lm.
Supply voltage and frequency
There are two main voltage and frequency standards most common in the world:
American - 100-127 volts 60 hertz;
European - 220-240 volts 50 hertz.

The package indicates the mains voltage range at which the lamp will work. The wider it is, the more likely the light bulb will cope and not burn out in case of voltage change in the mains.
Our lamps work in both voltage standards.

Color temperature
The color temperature of a lamp is the color tone of the light, measured in Kelvin (K). In life, we deal with a range from 1500 to 9000 K. According to this, light can be divided into three groups:
1500-3500 K

Candlelight (1500K), incandescent lamp (2200-2800K), sunset light (3400K). Warm light has a calming effect on a person, as it is associated with the end of the day, sunset.
These lamps are recommended for use in bedrooms, over dining room sets, for floor lamps, and wherever it is necessary to create a cozy atmosphere.
4000-5500 K
The light that simulates daylight (5000 K - sun at noon). Creates a working mood, used for general lighting (chandelier or spots), workplace, kitchen, office.
over 6000 K
With a short exposure, such lighting increases efficiency and concentration of attention, with prolonged exposure it causes fatigue and depression.
Cold light is often used in rooms, where a person spends a small amount of time, or in workplaces, where increased accuracy is required: a nail salon, a jewelry workshop, an operating room. It is unacceptable to use lamps with cold lights in children's rooms.
Color temperature not only creates a mood but also allows you to emphasize the color of the walls and affects the overall perception of the interior.

Walls in warm colors will look brighter with warm light bulbs. Finishing in cold colors, on the contrary, will look more effective in the rays of cold light. Neutral color temperature will not affect the color perception of the environment.
It is necessary to use lamps with different color temperatures in the same room with caution. The light in the room must remain harmonious.
For residential premises, it is better to choose lamps with neutral or warm light from 2700 to 4000 K.
Color rendering index (CRI)
The light from some lamps dims the colors of objects. Sometimes colors are difficult to distinguish. Eyes get tired quickly, the atmosphere in the room becomes uncomfortable and annoying.
It's all about the color rendering index (CRI or RA). It is the ability of a light bulb to authentically display the colors of the objects it illuminates. Values range from 1 to 100, where 100 is the best color rendering. For residential premises, this figure should be at least 80.
To check the color quality, look at your hand under the light of a lamp. If the hand becomes gray, then the lamp has a low color rendering index.
Ripple factor
This is the intensity of the lamp flickering. The visible pulsation of light causes discomfort and fatigue.
Lamps with a ripple factor above 10% are not worth buying.

The exact level of ripple can be determined by special devices, but even with the help of an ordinary smartphone camera, you can check it.
Point your phone's camera at the glowing lamp, as shown in the video below. A high-quality lamp with a low ripple coefficient will give a clear picture, without streaks of light and shadow.

Other parameters
Above are the main parameters that determine the choice of lamp. There are also specific characteristics that do not affect the quality of the light but are necessary in some situations. For example, IP or degree of protection against moisture and dust or dimmability. This parameter is relevant to learn if you plan to use the lamp in wet rooms or outdoors. IP 00 is the minimum protection class, IP 68 is the maximum protection against moisture and dust.

Dimming makes it possible to optimize the brightness of the lamp. Not all LED bulbs are dimmable and may create unpleasant ripples. This is due to how LEDs work. If multiple lamps need to be dimmed, smart lamps can be a good alternative.
Lighting affects our well-being, as well as the perception of surrounding objects. Therefore, buying a lamp should be approached deliberately: choose products from trusted manufacturers and be sure to study the information on the package:
Luminous flux.
For local lighting over a dining table or workplace - 600-700 lm, for decorative lighting (wall lamps, table lamps) - 400-600 lm.
Color temperature.
For a cozy atmosphere in residential premises - warm light 2700-3500 K.
For the work surface or office, general lighting in the children's and living rooms, or in the kitchen - neutral light 4000 K.
For work areas with high-precision activity - cold light over 6000 K. Do not use cold light bulbs in the children's rooms.
Color rendering index (CRI or Ra).
CRI for residential and office premises should be above 80, for children's rooms it is recommended to be above 90.
Ripple factor.
Should be no more than 10%. Check at the manufacturer's website.
