Introduction to bulbs and tubes

Light bulbs and tubes are electrical devices designed to produce light using different technologies and physical principles. They are fundamental components in lighting systems, both in residential, industrial and commercial spaces. While spotlights generally refer to incandescent, halogen, fluorescent or LED lamps that offer light in a compact format, tubes are typically linear lamps used to illuminate large areas with an even distribution of light.

These devices have evolved considerably, adapting to the demands of energy efficiency, durability and lighting quality. The choice between spotlights and tubes depends on the type of application, the type of luminaire and the conditions of use, as well as the technology used to generate the light.

Incandescent and Halogen Bulbs

Incandescent light bulbs were the first electric lamps widely used. They work by heating a tungsten filament that emits visible light when it reaches high temperatures. Although they provide a warm and pleasant light, their energy efficiency is low, since most of the energy is lost as heat.

Halogen bulbs are an improved variation of incandescent bulbs. They incorporate a halogen gas that allows the filament to operate at higher temperatures, increasing efficiency and lifespan. Their light is brighter and has better color rendering, but they still generate significant heat.

Fluorescent Lamps and Fluorescent Tubes

Fluorescent lamps work by exciting a gas and a fluorescent coating that converts ultraviolet radiation into visible light. Fluorescent tubes are the most common formats, characterized by their elongated shape and their use in general lighting and large spaces.
