Fluorescent lamps

A fluorescent lamp is a low-pressure mercury discharge lamp used as a light source. It consists of a fluorescent body, the basis of which is most often a long glass tube with incandescent electrodes, filled with mercury vapor and argon. A glow discharge occurs in them, which, however, shines mainly in the invisible ultraviolet region. This radiation falls on the walls of the tube, which are usually covered with a phosphor. This substance absorbs ultraviolet radiation and itself shines in the visible region. The fluorescent lamp thus shines.

For a gas discharge, the higher the current, the smaller the voltage drop across the discharge. Therefore, the current through the fluorescent lamp connected in the circuit must be limited in a suitable way, e.g. by a series resistor, a choke (in AC circuits) or an electronic ballast . The main part of the fluorescent lamp consists of a fluorescent tube containing mercury vapor and argon, and at both ends there are bases with metal electrodes.

We offer many types for different purposes

• White with different color temperatures . Typical color rendering is sometimes referred to by the abbreviated names Daylight, Cool white..
• Germicidal – usually without a phosphor, as a source of ultraviolet radiation for various purposes, especially for the destruction of microorganisms, bacteria, fungi, yeasts and viruses
• Full Spectrum - For plant cultivation - for growth and flowering, providing the right light conditions for plants

Advantages of fluorescent lamps

• Longer lifespan than classic tungsten bulbs, but shorter than LED light sources.
• Relatively high energy efficiency… 20% or more.
• Fluorescent lamps heat up significantly less than incandescent lamps.
