DESCRIPTION OF STANDARDISED TECHNICAL PARAMETERS

• APPROVAL – the most important thing to look for when choosing automotive bulbs and lamps is the approval certificate that allows the product to be used safely on the road.
• VOLTAGE U – it refers to the maximum voltage (expressed in volts (V)) that, when applied continuously to the bulb or lamp, will not cause damage to the product while providing optimum lighting performance over its lifetime.
• POWER CONSUMPTION P – it refers to the power consumption (expressed in watts (W)) of the bulb or lamp required by relevant standards to produce the correct amount of light of a given colour. Low quality bulbs often exceed current power consumption standards, causing damage to the car’s electrical system.
• LIFETIME B3 – it is the time (in hours) at which 3% of the tested bulbs or lamps have failed.
• LIFETIME Tc – it is the time (in hours) at which 63.2% of the tested bulbs or lamps have failed.
• LUMENS – it refers to the luminous flux of light expressed in lumens (lm). It determines the power of light in relation to the visual sensation of the human eye that a given model of bulb or lamp produces. It characterises the sensitivity of the human eye. This does not mean that light with twice the luminous flux will be perceived as twice as bright by the human eye.
• COLOUR TEMPERATURE Tb – this is an objective measure of the colour impression of a given light source (expressed in degrees of Kelvin (K)).
  - Warm white (~ 2900 – 3300 K)
  - Daylight white (~ 4000 – 4500 K)
  - Cold white (~ 5000 – 6500 K)
• MOUNTING TYPE – it determines the unique type of bulb or lamp attachment. The parameter represents the correct position of the bulb in relation to the reflective parts of the lamp for its correct installation.
