Which statement is FALSE?

The statement about incandescent lamps maintaining their output better than halogen lamps is indeed false. Halogen lamps are a type of incandescent lamp that has been modified to include a halogen gas, which allows these lamps to operate at higher temperatures and improves their luminous efficacy. As a result, halogen lamps can maintain their light output more consistently over time when compared to standard incandescent lamps.

In incandescent lamps, the output tends to decrease more significantly as the tungsten filament ages, leading to reduced efficiency and light output. Conversely, halogen technology helps to minimize the degradation of light output, making them a more reliable choice for maintaining consistent brightness throughout their lifespan.

The other statements accurately reflect the characteristics of incandescent and halogen lamps. Both types indeed utilize tungsten filaments, and halogen lamps are more efficient than traditional incandescent lamps, with efficiencies commonly exceeding 30 lumens per watt (LPW).
