Signal bulbs
Signaling bulbs are intended, among others, for: for special signaling tasks in industry and mining, therefore they are adapted to work in difficult conditions in which other light sources may malfunction. The signal bulbs in the EL12 range feature a reinforced light system design, making them extremely resistant to vibrations. This is especially important when they are used as auxiliary bulbs in motor vehicles and as signaling in machines and switchboards. Such bulbs are also characterized by greater durability compared to standard lighting. They will prove themselves in harsh industrial working conditions - including places where other light sources cannot be used due to elevated temperatures or increased humidity. Signaling bulbs in the EL12 offer differ due to the shape of the lampshade, so they can be easily matched to the mounting location (e.g. a tubular bulb is intended for use wherever there is little space for mounting). Other important parameters that are worth paying attention to when buying include: bulb length (given in millimeters), power (given in watts or lumens), luminous flux (given in lumens), durability (specified in working hours) . There are also markings on the packaging of light bulbs that define the so-called energy efficiency class. It is the ratio of the efficiency to the current consumption of the bulb. According to the European Union directive, any lighting fixture with a power greater than 30 lumens must have such a label. The classes are marked with the letters A, B, C, D and E, respectively, where A means the highest efficiency, which is mainly characterized by LED bulbs. The others are energy classes characterized by a lower ratio of efficiency to energy consumed. They include e.g. halogen lamps, xenon lamps or traditional incandescent bulbs.
