Leuchtmittel – Fluorescent Lamps
Fluorescent lamps produce light by passing electrical current through a gas, offering significantly better efficiency than incandescent lamps. The range covers linear lamps (T8 tubes G13, T5 tubes G5), compact fluorescent lamps (energy-savers with screw and pin bases) and specialist fluorescent lamps for specific applications. All fluorescent lamps require a ballast (starter for magnetic, or electronic ballast). T8 tubes (G13 base): Diameter 26 mm, lengths 60 cm (18 W), 120 cm (36 W), 150 cm (58 W). Standard in industry, office and school for decades. Colour codes: 827 (warm white), 830, 840 (neutral white), 865 (daylight). T5 tubes (G5 base): Diameter 16 mm, more compact and efficient than T8. Electronic ballast only. Lengths 28 W (115 cm) and 35/54/80 W. Compact fluorescent lamps: Integrated ballast in the base (screw E27/E14, pin G23/G24). Lifespan 8,000–15,000 h. Disposal note: contain mercury – hazardous waste disposal required. Colour code (tri-phosphor system): First digit = CRI class (8xx = CRI 80+, 9xx = CRI 90+). Last two digits = colour temperature (27 = 2,700 K, 30 = 3,000 K, 40 = 4,000 K, 65 = 6,500 K). Applications: office and workshop lighting (T8/T5), refrigeration and deep-freeze (specialist tubes to –25 °C), UV applications (blacklight, disinfection). LED tube retrofit possible – socket adapters and bypass kits available. Expert advice: +49 (0)7666 / 88499-0 | sales@industry-electronics.com | Top manufacturers

Fluorescent Lamps – FAQ
What is the difference between magnetic and electronic ballast?
Magnetic ballast (KVG): lower cost but higher losses and possible 50 Hz flicker. Requires a starter. Electronic ballast (EVG): high-frequency operation (>20 kHz), no flicker, higher efficiency (+25 %), soft start, longer lamp life. Recommendation: electronic ballast for new installations.
How do I read the colour code on fluorescent lamps?
Example ‘840’: 8 = CRI 80+, 40 = 4,000 K neutral white. ‘827’: CRI 80+, warm white 2,700 K. ‘865’: CRI 80+, daylight 6,500 K. Details: .
How do I dispose of fluorescent lamps?
Fluorescent lamps contain mercury and must NOT go in general waste. Free return at electrical retailers or recycling centres. As a trade customer: observe disposal documentation requirements under ElektroG.
