Advertising and advertorials in all mediums including, technical magazines, newspapers, radio and TV, are creating the impression that LEDs are the cure for energy shortages, pollution and global warming. They will apparently miraculously eliminate the need for hundreds of additional power stations by 2020.

 

LEDs are a significant and evolving technology, in which great strides are rapidly being taken. However, LED light sources, ranging from LED lamps of various shapes and configurations, and LED fixtures, are not the answer for all lighting applications and requirements. Yet often, despite the simple arithmetic calculations which would refute the argument for LEDs - based on cost versus benefit, LEDs are installed. It seems that LED light sources are as much about fashion as about science.

 

Take note

  • In any lighting installation, it is important to be aware of the necessary light levels.
  • LED light sources have a place, but be sure to understand that place.
  • Environmental issues are best solved by an holistic, carefully considered approach, rather than seeing one or other specific technology as a panacea.
