While comparing tungsten filament lamps with fluorescent tubes, all of the following are the advantages in favor of tungsten filament lamp EXCEPT Longer life.

Tungsten filament lamps and fluorescent tubes are both types of electric lamps used for lighting purposes. Here are some of the differences between them:

1. Energy efficiency: Fluorescent tubes are more energy-efficient than tungsten filament lamps. They convert more of the electricity they use into light and less into heat. This means that they use less electricity to produce the same amount of light as a tungsten filament lamp.

2. Lifespan: Fluorescent tubes have a longer lifespan than tungsten filament lamps. Fluorescent tubes can last up to 20,000 hours, whereas tungsten filament lamps usually last around 1,000 hours.

3. Cost: Tungsten filament lamps are cheaper to purchase than fluorescent tubes.

4. Color temperature: Tungsten filament lamps produce a warm, natural light that is similar to sunlight, while fluorescent tubes can produce a range of colors, from cool white to warm white.

5. Flicker: Tungsten filament lamps can be dimmed without flickering, while some fluorescent tubes can flicker when dimmed.

6. Environmental impact: Fluorescent tubes are more environmentally friendly than tungsten filament lamps because they use less energy and have a longer lifespan, which reduces the need for replacements and disposal of used lamps.
