Your question: Why are fluorescent light bulbs better than incandescent?

Fluorescent light bulbs are more energy-efficient than incandescent bulbs. … They take time to reach their full brightness and tend to be slightly more expensive than incandescent bulbs but last much longer. There is some concern about the fact that they contain mercury.

What are the advantages of using a fluorescent bulb instead of an incandescent bulb?

Fluorescent lamps also do not produce as much heat as traditional lighting options. They make about 75% less heat compared to an incandescent bulb because they are not using resistance to emit light. That also results in an energy savings, and also helps to keep whatever room they are in at a cooler temperature.

What are the advantages of fluorescent light bulbs?

Fluorescent Light Tube Advantages

  • Energy efficient- so far the best light for interior lighting.
  • Low production cost (of tubes, not of the ballasts)
  • Long life of tubes.
  • Good selection of desired color temperature (cool whites to warm whites)
  • Diffused light (good for general, even lighting, reducing harsh shadows)
