Benefits of LED

The benefits of LED products versus traditional light source products include:

  • Long life
  • Consistency of light quality
  • Low power consumption
  • Low Maintenance - slow failure rather than sudden outage
  • Low voltage - better for hazzardous areas
  • Easier control on coloured lighting
  • Robust/durable - physically, shock and vibration resistant
  • No IR or UV emitted
  • Environmentally greener
  • Controlability - instant light with dimming and frequent switching capability
  • Absence of toxic substance - no mercury
  • Easy to recycle

When choosing the right LED, issues to consider include:

  • Lumen per watt (energy efficacy)
  • Cost per lumen
  • Colour quality, CRI
  • Colour consistency , binning
  • Lens choice
  • Thermal issues
  • Manufacturing issues
  • Reliability (not just LED also for example solder joints)
