Plug-in socket lamps

Plug-in socket lamps are common in work and ceiling luminaires, for example. An electronic ballast transforms the supply voltage to suit the lamp. Compared to magnetic ballasts, the advantages of electronic ballasts are flicker-free light, better light efficiency, a longer lamp lifetime and higher energy efficiency. The products are packed in cardboard boxes that clearly present the product information. The colour temperatures are pure white and cool white (3000 K/4000 K).
