WebMay 7, 2024 · Fluorescent lamps are about 2 to 4 times as efficient as incandescent lamps at producing light at the wavelengths that are useful to humans. Thus, they run cooler for the same effective light output. The bulbs themselves also last a lot longer—10,000 to 20,000 hours versus 1,000 hours for a typical incandescent. port stephens sheds \u0026 constructionsiron weight calculationA fluorescent lamp, a device with negative differential resistance.
