Incandescent Lamp Testing

Incandescent lamps, commonly known as tungsten lamps, are electric light sources that heat the filament to an incandescent state and use thermal radiation to emit visible light. The periphery of the incandescent bulb is made of glass, which keeps the filament under a vacuum or a low-pressure inert gas (such as a halogen lamp) to prevent the filament from oxidizing at high temperatures.

Incandescent lamp testing is done to determine the performance and quality of the lamp. The testing can provide valuable information such as light output, power consumption, lifespan, color temperature and more. By testing these lamps, manufacturers can assure customers of their product's quality, safety, and performance, which boosts consumer confidence and product credibility.

STEMart provides comprehensive and reliable incandescent lamp testing services to evaluate the performance characteristics of incandescent bulbs, and ensure that the lamps meet or exceed industry standards and consumer expectations.
