What does the IP parameter mean?

The IP protection class is a parameter that characterizes the device casing, informing about the protection provided by the casing against access to hazardous parts, the ingress of foreign solids and the ingress of water. Depending on the degree of IP protection, the device can operate in various environmental conditions.

The first characteristic digit (in accordance with PN-EN 60529: 2003)

0– without protection

3 -protection against spraying water at any angle up to 60 ° from the vertical on all sides
4 - protection against splashes of water from any direction

8 - protection against the effects of continuous immersion in water (the housing is still immersed in water, in conditions agreed between the manufacturer and the user, but stricter than according to number 7)
9 - protection against flooding with strong water jets under pressure (80-100 bar and temperature + 80 ° C) in accordance with DIN 40050

Additional letter (in accordance with PN-EN 60529: 2003)

A - protection against access to dangerous parts with the back of the hand
B - protection against access to dangerous parts with a finger
C - protection against access to dangerous parts with a tool
D - protection against access to hazardous parts by wire

Supplementary letter (in accordance with PN-EN 60529: 2003)

H - high voltage devices
M - testing the harmful effects of water penetration when moving parts of the device (e.g. rotor of a rotating machine) are in motion
S - testing the harmful effects of water penetration when moving parts of the device (e.g. rotor of a rotating machine) are stationary
W - suitable for use in certain weather conditions with additional treatments or protection measures

What does the PF (power factor) parameter mean?

Power factor - is a measure of the use of electricity (active power) by the device in relation to the energy supplied to it (apparent power). It determines what part of the energy taken from the network will be used effectively by a given device. If an element of the circuit has this factor lower than one, then we start dealing with energy that has been consumed but not used (reactive power), which is converted into unfavorable phenomena, e.g. heat emission. The table shows the permissible PF values ​​depending on the electrical power for LED lamps:
Functional parameter Requirement from step 1 onwards unless otherwise stated
Power factor of lamps with built-in control gear
  • P≤2 W: no requirement
  • 2 W & lt; P≤5W: PF & gt; 0.4
  • 5 W & lt; P≤25W: PF & gt; 0.5
  • P & gt; 25W: PF & gt; 0.9

What is luminous efficacy?

This is otherwise the luminous efficiency, i.e. the ratio of the luminous flux to power of the light source, measured in lumens per watt (lm / W). The higher the efficiency, the more lumens generated by 1Watt of power and the light source is more energy-efficient.

What are Lumens?

Lumen [lm] is a unit of luminous flux.

What is luminous flux?

Luminous flux is the total power of visible light emitted from a given light source. The greater the luminous flux, the more light that evokes specific visual impressions and the better illumination of lited area. The luminous flux increases with power of a given source.

What is the colour temperature and which one to choose when purchasing new lighting?

The colour temperature determines the colour of the light emitted by a light source. It is expressed in Kelvin [K] and is a measure of the colour impression of a light source. The lower - below 3000K - the colour is closer to yellow, orange, to red - it is the colour temperature of heat. High colour temperatures above 5000K are close to the blue color, i.e. cool. The universal colour temperature is 4000K.

What bulb power should you choose compared to conventional incandescent bulbs?

Conventional light bulbs were distinguished by the power they generated. For many years of habits, such names have left a permanent mark. Despite the withdrawal of traditional filament bulbs from circulation and replacing them with energy-saving LED sources, we are still looking for equivalents of "old light bulbs" to help us choose the right lighting. Currently, to determine how bright the LED light source will shine, compare the luminous flux it emits. In the table below we have compiled an approximate comparison of LEDOM bulbs and a traditional light bulb. As you can see, the power consumption of LEDOM bulbs is five or even eight times lower than that of a traditional bulb with a similar luminous flux. When selecting the luminous flux, the appropriate color temperature should also be selected.

What bulb power should you choose compared to conventional incandescent bulbs?

There are many types of bulb caps. There are a few of the most popular ones, and they are labeled with letters and numbers. The letter E stands for screw-in handles and comes from the first letter of Thomas Edison's surname, who first patented the bulb, the letters G or GU stand for push-in handles.

E27 - the so-called "Large thread", its diameter is 27mm. It is the most common socket in light bulbs. It gained its popularity through the traditional light bulb, which was used all over the world since the mid-nineteenth century. Bulbs with an E27 base are adapted to a voltage of 230V. LEDOM's offer includes LED bulbs with such a cap.

E14 - the so-called "Small thread", its diameter is 14mm. It is an equally common handle next to the E27. It is a smaller version of the E27 screw cap and was used in traditional reduced wattage bulbs. Most often used in bedside lamps, wall lamps and chandeliers, the so-called "Candle" lamps, where one chandelier had several or a dozen smaller bulbs. Currently also used in LED bulbs, also available in the LEDOM offer. Bulbs with an E14 socket are also suitable for 230V.

GU10 - the handle of such a bulb is mounted by pressing, and then turned by ¼. The number 10 means 10mm spacing between two pins, which are the main connector of the bulb with the power socket. It originated in the fixtures in halogen bulbs, currently one of the most commonly used sockets in LED bulbs. Used for spot lighting, as well as in suspended ceilings. They are also available in the LEDOM offer, adapted to the voltage of 230V.

G4 - The G4 handle is press-fitted. The number 4 means 4mm spacing between two pins, which are the main connector of the bulb with the power socket. Bulbs with this thread are mainly used as decorative lighting. Used in desk lamps, floor lamps or cooker hoods, ovens and furniture. They are also available in the LEDOM offer, operating at 12V, require a transformer (power supply)
