The Conventional Incandescent Bulb

The Conventional Incandescent Bulb

It will soon disappear from stores, if not energy efficient. However, it has some advantages!

Advantages of conventional incandescent bulb:

  • A warm light for relaxation;
  • A continuous spectrum, so comfort for the visual system;
  • Instant start;
  • The ability to be used with a dimmer without damage;
  • It is silent, without oscillation or growl;
  • It contains no toxic or hazardous material;
  • It is found in a wide range of sizes, shapes and powers;
  • It heats! This is an advantage and a disadvantage winter summer.

Disadvantages of conventional incandescent bulb:

  • Its short life last from 1000 to 1200 hours. This partly explains its imminent demise. Its price is low (about $ 2 for a bulb base), but we must buy regularly.
  • Its fragility: it resents vibrations, surges, and high ignition / extinction regime.
  • 90% of the power is dissipated as heat (see above): it is therefore objectively ineffective, which is another reason for its demise.
