Voltage

Operating voltage of the auto lamp.

In different types of equipment, the voltage of on-board networks is also different. Therefore, car lamps for passenger cars are designed for a voltage of 12 V, and car lamps for trucks(and other similar equipment, such as buses) are designed for 24 V. However, there are also more specific options:

12/24 V. Lamps with the possibility of use in both types of on-board networks - both passenger cars and trucks. This versatility is found mainly among LED models, as well as in some types of xenon (see “Type”): these types of lamps are equipped with control circuits that can automatically adjust to the on-board network voltage.

— 85 V. Value found in models with xenon operating principle (see “Type”). In this case, we mean the voltage supplied to the lamp from the ignition unit (see below); the ignition unit itself is connected to the on-board network and is usually designed for 12 V. Data on the operating voltage of the lamp itself may be needed if you need to select a separate ignition unit for it.

- 40 V. Another option for increased voltage in xenon lamps; the meaning is completely similar to the 85 V described above, but is much less common.

Brightness

Luminous flux produced by a car lamp; for dual-mode models like bi-xenon (see “Type”), the value at maximum brightness is indicated.

This parameter characterizes the actual brightness and efficiency of the lamp; it can be used to directly evaluate and compare different models, regardless of their type and power consumption (but only at the same color temperature - see below for more details). The brightest are headlight lamps (see “Purpose”), in them this indicator can exceed 4000 lm and vary noticeably from model to model. Therefore, when choosing such a lamp, you should pay special attention to the characteristics of the luminous flux. It should be borne in mind that too bright headlights are just as undesirable as too dim ones: high brightness creates not only the risk of dazzling for oncoming cars, but also discomfort for the driver himself. Optimal luminous flux values can be indicated in the documents for the car or for the headlight itself; if such data is not available, you can turn to other special sources.

As for other types of lamps, in models for auxiliary lighting the luminous flux is up to 800 lm, and in lamps for the instrument panel - up to 55 lm. Moreover, in both cases, the brightness is selected by the manufacturer taking into account the specific specialization and location of the lamp, so in such models this parameter is not a key one.
