Rating of the best lux meters for 2024

Quite often in practice, there are cases when it is necessary to measure the level of illumination of a room or determine the brightness of the lights. In this case, a light meter will come to the rescue. With its help, you can easily identify places with a lack of light, and then eliminate them.

How it works

Today, such devices have different designs and functionality, which are constantly being modified and improved. You can also often find devices that can measure not only the level of illumination, but also other parameters of light, such as brightness or ripple. Still, the main working component of such a device, regardless of its functionality, is a photocell. It is a sensor where photons transfer their light energy to electrons, which leads to the formation of an electric current. The amount of current will depend on the light level. Also, to get an accurate reading, each light meter has an indicator. If the device is mechanical, then this indicator begins to act on the arrow, it rotates, and according to these indicators, you can get the exact value. There are also digital lux meters. Here, the received analog signal is converted using a converter, and then the readings are displayed on the display.

Types of light meters

• By design.

First of all, this device for measuring illumination can be classified according to design features. These devices come with a remote or built-in sensor, which can also be called a monoblock.

The first option is convenient to use in hard-to-reach places, since the connection to the sensor is carried out using a wire. In a monoblock, such a sensor is fixed to the body, which does not make it possible to take measurements in places with limited access, but is suitable for obtaining quick results. Also, this version of luxometers can have a removable sensor, which increases the measurement capabilities.

• Mechanism or number

As mentioned above, indicators for devices can be mechanical or digital. In terms of accuracy, devices with an indicator in the form of an arrow are inferior to digital devices. Even more mechanical devices, although it is quite convenient to use them.

• Functional

Lux meters can be classified according to their functionality. The simplest and most budgetary options are household devices. They can only measure the level of illumination, their indicators are not very accurate, but the measurement is quite fast. There are more expensive home appliances available. They have internal memory, and the result is the average of several measurements.

Professional models are used to obtain accurate results. Their main difference from household luxmeters is the presence of light filters.These filters are able to bring the sensor sensitivity closer to that of the human eye. Thanks to this, the indicator of light metering is improved, as well as various shades. If such a device is installed outdoors, then in addition it has an absorbing filter. The error of such models is about 1%. Professional models can have additional sensors in their design, with which you can measure the brightness of luminous objects or objects.

There is a luxmeter-heart rate monitor. Besides its main function, it is able to measure the flicker factor of various devices. For example, TV screens, smartphones or monitors. But there is also a universal device that can determine the level of illumination, brightness and flicker. This option will have the highest cost among all the light meter options.

Terms of use

To take readings of the light level with a mechanical light meter, it must be placed on a horizontal surface. It will be necessary to install a special nozzle on the photocell. Each of the nozzles has its own coefficient of attenuation of the light flux. After that, you need to press the button and take the readings. If the reading with the nozzle is less than 30 Lx, then the measurement should be repeated without the nozzle. Before starting work, make sure that the pointer of the device is at zero. Otherwise, using a corrector and a screwdriver, it should be brought to the zero position. No shadow should fall on the photocell, otherwise the result will not be correct. Devices with electromagnetic radiation can affect the measurement error, so it is advisable to turn them off before measurements and, if possible, remove them.

It is easier and more convenient to use an electronic device. To do this, you just need to turn on the device and select the appropriate function. After that, the device itself will choose the required coefficient and measure it. The results will be displayed.

Note that natural and artificial light readings must be taken separately. There should be no movement during the reading as this will affect the result.

After the results have been taken, they are recorded and calculations are performed. The calculation result should be checked against the permissible standards.

Criterias of choice

Before buying such a device, you should decide with what type of lighting you will carry out measuring work. Each light meter has its own measurement range and spectral sensitivity. And based on this, each model has its own purpose. For example, one option is suitable for working with sunlight, and the other is suitable for neon lamps. But you can pick up a universal device that has a switch. Thanks to this, it will be possible to work with different light sources.

The size of the device plays an important role when choosing a product. The compact size will be more convenient to use, and it does not need a lot of space during storage. To make the operation comfortable, it will be more convenient if the parting does not work from the mains. In this case, you will not need to look for an outlet or, if necessary, use an extension cord. In addition, wires can interfere with work.

There are luxmeters, the functionality of which allows, in addition to the main measurement of the illumination level, to carry out additional measurements. For example, temperature, noise level or pressure. The cost of this option will exceed the price of a household appliance. But if you need these indicators, then it will be cheaper and more practical to combine them into one device.

If you decide to purchase an electronic lux meter, pay attention to the size of its screen. The larger the display, the more convenient it will be to take readings. To work in the dark, you will need a backlight. It is preferable if the device will have an internal memory to store the results. This will enable comparative analysis.

The cost of such measuring devices can vary from 1000 rubles and go up to several tens of thousands.If you take measurements less often and only work with lighting, you should not take the expensive option. Such devices have extensive functionality, which may not be useful to you, but this will significantly increase their price.
