The scattering angle is in the range from 60 to 340°. LEDs enclosed in bulbs are characterized by a narrow beam of light. The so-called corn bulbs spread light around themselves.
The nominal voltage indicates the supply netherlands email list 6 million contact leads current that the lamp requires – 12, 24, 110 or 220 V.
If you decide to replace your old light bulbs with more modern and economical lighting, then first calculate the required power of the light sources.
A simple formula allows us to determine this
How to calculate 1 lx (illuminance = 1 lm (luminous flux of the lamp) x 1 m² (room area).
According to the current building codes and regulations SNiP, the degree of illumination of the room is established depending on its purpose. We divide this ready coefficient by the square of the room and get the result with the data of the luminous flux. To achieve it, the necessary bulbs are selected.
Expert advice: mathematical calculations why do you need to use videos in your marketing strategy? do not take into account certain
nuances regarding the preferences of residents, zoning of the premises or the purpose of lighting – auxiliary or main. This can lead to significant differences, for example, light is needed to illuminate a room or create some kind of designer image using lighting. The difference also concerns one’s own attitude to comfort: some people like dim light, while others need to ensure a rich light flow.
Also, lighting fixture manufacturers offer
Various designs that differ in the number of lampshades and direction vector.
To sum up, we can say that LED lamps are simple and have virtually no disadvantages:
with their help you can significantly reduce household and utility costs;
they provide high-quality mobile lead lighting;
are safe and durable products, and also erase any boundaries for creative imagination.

5. The number of poles is another important selection criterion. For a single-phase 220-volt network, it is recommended to select a two-pole single-phase circuit breaker for the input.
