Tungsten Halogen Lamps
Comparison photograph of two types of tungsten halogen lamps. The larger lamps is rated at 1000 W 240 V mains voltage. It is suitable for luminaires that light large areas as found in television and film studio production. It is characterised by the larger and thicker tungsten filament. The smaller lamp, at 50 W 12 V, is one of the low voltage lamps having a well defined tungsten filament that provides the small filament field and thus a small source that is necessary in precisely aligned optical systems such as microscope lamps, introscopes and projection equipment. The power supply is usually direct current (DC). Both lamps have the standard GX6.35 base with connection pins at a separation of 6.35mm

EDITORS COMMENTS
This print showcases a fascinating comparison between two types of tungsten halogen lamps. The larger lamp, rated at an impressive 1000 W and operating at 240 V mains voltage, is specifically designed to illuminate vast areas commonly found in the production of television and film studios. Its distinguishing feature lies in its larger and thicker tungsten filament, which ensures a powerful light source. On the other hand, the smaller lamp operates at a lower voltage of 50 W and 12 V. This type of low voltage lamp boasts a well-defined tungsten filament that creates a small filament field, making it ideal for precisely aligned optical systems such as microscope lamps, introscopes, and projection equipment. Typically powered by direct current (DC), this compact lamp provides exceptional precision in various applications. Both lamps share the standard GX6.35 base with connection pins separated by 6.35mm—a widely recognized industry standard for compatibility across different lighting fixtures. The intricate details captured in this photograph emphasize the importance of these specialized tungsten halogen lamps within their respective fields—whether it be illuminating expansive studio sets or enabling precise observations through microscopes or projectors. Science Photo Library has beautifully documented these essential components that play crucial roles behind-the-scenes without mentioning any specific commercial use or company affiliation.
