Technical specs

Energy class
The energy class scale on energy labels for light sources has changed since September 1, 2021. You will no longer find energy class with "pluses" on our products, as the scale will now be at the lower end of the scale at the current state of technology. Our light sources are still keeping the same excellent energy efficiency, only the metrics have changed. To keep it simple, just stick to the fact, that the earlier the letter in the alphabet, the more energy efficient the product is.
G
Head type
The shape of the head determines the deflector shape design at the light source. This parameter is important because some luminaries have limited interior space. Also, the head shape determines whether the light will be directed into space or, conversely, more spot-focused.
R50
Socket thread
The socket or thread is the connecting part of the light source with the luminary. There are many types of sockets, but the most commonly used are those with Edison thread E14 and E27, then the bayonet GU10 and pin socket GU5.3 (MR16). Small bulbs use a G9 or G4 socket for a change.
E14
Voltage
The operating bulb voltage at which the bulb shows the specified luminous flux parameter. Conventional light sources are either designed for 230V mains voltage or are low-voltage (e.g. 12V)
220 - 240 V
Power input
Power input is a physical quantity that expresses the amount of energy consumed by an appliance per time unit. The smaller the value, the more economical the product, but also less powerful.
42 W
Economical equivalent
The economical equivalent is simply to compare the consumption of a light source with a conventional tungsten filament bulb with the same luminous flux.
60 W
Version
The parameter defines the light source design. It can be, for example, a miniature, compact or large power bulb.
Reflector
Lifetime
The service life of modern light sources is many times higher compared with tungsten filament light sources. The value expresses the number of hours that the light source is able to emit without appreciable loss of luminous flux.
2000 h
Luminous flux
Luminous flux. It’s denoted by the letter Φ and the unit is lumen (lm). Indicates the light energy that the source emits in 1 second. Thus, it is a form of power. The higher the value, the more light the light source emits.
375 lm
Color rendering index
The Colour Rendering Index (CRI) is an assessment of colour fidelity, when illuminated by a given source versus solar illumination. The Ra unit determines the fidelity of the colour perception to the human eye CRI, which is produced by the light source itself. The value of Ra is given as an integer from 0 to 100. Simply put, imagine the value of CRI Ra = 0 at which we do not recognize any colour, at the value of CRI Ra = 100 it is an ideal light source with a natural colour rendering. The lower the CRI value, the more the colours are faded and unnatural. On the contrary, the higher the number, the more vivid and natural things will look.
99
Beam angle
The radiation angle of a light source is the angle at which the light is emitted into space. However, the light is scattered in space, so it can be seen that even after a certain limit of the angle of radiation, the light is still shining, but it is weak and no longer illuminates anything.
140 °
Number of starts
The parameter approximately defines the maximum possible number of the light source’s light on/off cycles. This is an important lifetime-related parameter.
100000
Color temperature
Colour temperature, in professional terms the temperature of chromaticity, is the expression of the colour of light emitted by a luminary. It is denoted by the letter K - Kelvin. In general, the lower the Kelvin value, the warmer and darker the light is. E.g. the wax candle light is 1,900 Kelvin. In contrast, a fluorescent lamp can have about 6,000K.
2700 K
Colour of light
Warm white, cold white, daytime white. This is a verbal indication of colour temperature (in professional terms, chromaticity temperature). Basically, it can be said that warm white has a light colour of yellow, cold white has a bright white light. Daylight white is already a slightly bluish light. The nomenclature may differ from brand to brand. For easy orientation, we mark our light sources with sun icons of the appropriate colour.
Warm white
Dimmability
Halogen, classic but only some LED lamps can normally be dimmed with common types of dimmers. The dimmability parameter means that the light source can be dimmed with conventional dimmers.
Length
The parameter indicates the diameter of the light source in mm. An important thing, especially if the luminary has limited space inside.
87 mm
Diameter
The parameter indicates the diameter of the light source in mm. An important thing, especially if the luminary has limited space inside or there is a limited diameter shade.
50 mm
