This article highlights the differences between Tungsten Filament Lamps and Fluorescent Tubes. Let’s dive into a comparison of these two lighting technologies.
Tungsten Filament Lamp vs. Fluorescent Tube Comparison
Here’s a table summarizing the key distinctions:
| Feature | Tungsten Filament Lamp | Fluorescent Tube |
|---|---|---|
| Light Quality | Close to natural light | Not close to natural light |
| Color Rendering | Actual colors can be judged | Actual colors cannot be judged |
| Initial Cost | Low | High |
| Lifespan | About 1000 Hours | About 4000 Hours |
| Maintenance Cost | High | Low |
| Brightness | More | Cool and pleasant light |
| Light Output over Time | Reduces with time | Reduces, but much less |
| Heat Radiation | Significant heat radiation loss | Less radiation due to lower temperature |
| Lumen Output/Watt | Less | More (around 40 lumen/watt) |
| Lumen Efficiency | Poor (especially with colored glass) | Depends on the gas used |
| Stroboscopic Effect | No stroboscopic effect | Has stroboscopic effect |
In simpler terms:
- Color: Tungsten lamps produce light closer to natural sunlight, allowing for accurate color perception. Fluorescent lights can distort colors.
- Cost: Incandescent bulbs are cheaper to buy initially, but fluorescent tubes save you money in the long run.
- Longevity: Fluorescent tubes last significantly longer than tungsten bulbs.
- Efficiency: Fluorescent tubes are much more energy-efficient, producing more light per watt of energy consumed.
- Other factors: Tungsten lamps create heat, while Fluorescent lamps do not.
