Socket

The type of base used in the lamp.

The base is the contact part of the lamp, which is fixed in the socket and is responsible for fixation, electrical connection and the possibility of safe removal. Thus, the type of base directly determines compatibility with a particular cartridge. However, in addition to this, there is also such a parameter as the base of the base. It determines primarily the contact configuration used on a particular base. And in our paragraph it is written as the second value.

In lamps for different purposes (see above), the set of bases used is very different. So, for the head light the following options are used: D1S, D1R, D2S, D2R, D3S , D3R, D4S, D4R, H1, H2, H3, H4, H7, H8, H9, H10, H11, H13, H15, H16, H27W /1, H27W/2, HB1, HB3, HB4, HB5, HIR2, HS1, M5, R2. For markers and other similar lights, in particular, C5W, C10W, C15W, H21W, H6W, P21W, PY21W, P21/4W, P21/5W, P27/7W, PR21W, R5W, R10W, T4W, W5W, WY5W, W16W are used , W21W, WY21W, W21/5W.

If desired, you can find a detailed explanation of each designation in special sources.

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.

Lifespan B3

Guaranteed lamp life according to B3 standard. In fact, this is the longest time that the lamp can continuously work with a 97% guarantee (it is impossible to provide a 100% guarantee in principle). This parameter is measured as follows: a test batch of lamps is used until 3% of them fail, the resulting time is indicated in the characteristics.

Other things being equal, longer-lasting lamps naturally cost more, but longer service life compensates for this disadvantage. Separately, we note that you should not confuse the guaranteed service life with the manufacturer's warranty — the conditions and warranty period may be different even for lamps with the same B3.

Increased brightness

The level of increased brightness provided by the lamp. This indicator is used by some manufacturers for marketing purposes: it describes how brighter a given model is than some "standard lamps". At the same time, the standards for comparison may be different, and impressive figures (in some models reaching 140%, that is, almost 2.5 times) are not always reliable — that is, a high-brightness lamp will not necessarily be just that much brighter than the “normal” model of the same type and power.
