Tungsten vs. Fluorescent: Lamp Comparison

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:

FeatureTungsten Filament LampFluorescent Tube
Light QualityClose to natural lightNot close to natural light
Color RenderingActual colors can be judgedActual colors cannot be judged
Initial CostLowHigh
LifespanAbout 1000 HoursAbout 4000 Hours
Maintenance CostHighLow
BrightnessMoreCool and pleasant light
Light Output over TimeReduces with timeReduces, but much less
Heat RadiationSignificant heat radiation lossLess radiation due to lower temperature
Lumen Output/WattLessMore (around 40 lumen/watt)
Lumen EfficiencyPoor (especially with colored glass)Depends on the gas used
Stroboscopic EffectNo stroboscopic effectHas 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.
