Which tubelight is better, LED or regular fluorescent?

  • Fluorescent lights contain mercury, a toxic substance that poses a waste disposal problem when the light is turned off. A limited quantity of hazardous mercury is released as a gas by broken bulbs, while the remainder is trapped in the glass itself.
  • Fluorescent lights are omnidirectional, which means light is emitted at a 360-degree angle. This is a significant system inefficiency because at least half of the light must be reflected and redirected to the desired location. It also means that more light fixture accessories are needed to reflect or focus the bulb’s luminous output (thus increasing unit costs).
  • Compared to other lighting technologies, LEDs have an extraordinarily long lifespan (including fluorescent lights). 
  • In comparison to other commercially available lighting technologies, LEDs are particularly energy-efficient.
