Light Bulb



Broken light bulbs can be harmful. Do not vacuum; pick up broken shards with a damp cloth. Wrap carefully and dispose of cloth and bulb fragments.



This Stuff article says "12 per cent of New Zealand's energy consumption was in lighting ..." A good reason to consider lower-energy lighting options! The electricity used over the lifetime of a single incandescent bulb costs 5 to 10 times the original purchase price of the bulb itself.

"If every New Zealand household installed LED lighting, we'd avoid 82,000 tonnes of greenhouse gas emissions every year - the emissions of almost 34,000 petrol cars." Check out other interesting information and hints with GEN LESS.

Here's a great article from the Intentionally Sustainable people describing the different kinds of light bulbs available and their pros and cons.

Reduce light bulb purchases by:

  • taking advantage of natural lighting where possible by opening curtains and blinds
  • asking your architect or builder if you are retrofitting or building a new house about where best to place windows or skylights to take advantage of natural light
  • installing timers or sensors which will help make your bulbs last longer by only having them on when needed
  • consider where you could cheaply replace outdoor lights with simple outdoor solar lights
  • changing to Energy-Efficient Light bulbs (EFLs) - mercury-free CFL (Compact Fluorescent Light) bulbs, LED or halogen lights



All types of lightbulbs - EFLs (LED, CFL and halogen light bulbs) and fluorescent tubes are collected at Mitre 10 MEGA for recycling. 


Broken light bulbs should be wrapped carefully if going in waste to landfill.
