Ballasts (363 companies)
Ballasts are power supplies or transformers for fluorescent lamps. Learn more about Ballasts

Fluorescent Lamps (348 companies)
Fluorescent lamps are high-efficiency lamps that use electrical discharge through low-pressure mercury vapor to produce ultraviolet (UV) energy, which is then transformed into visible light.

Halogen Lamps (190 companies)
Halogen lamps are high pressure incandescent lamps containing halogen gases such as iodine or bromine, which allow the filaments to be operated at higher temperatures and higher efficacies.

Heat Lamps (29 companies)
Heat lamps are also known as infrared emitters, infrared bulbs, infrared tubes, or infrared lamps. Heat lamps differ from illuminating lamps in their low filament temperature, resulting in much less light and more infrared radiation.
