Lighting

Lamps

• Compact fluorescent lamps should replace all tungsten filament lamps.
  
  
• Tungsten spot lights should be replaced with Tungsten halogen lamps.
  
  
• Standard 38mm diameter fluorescent tubes should be replaced with 26mm tubes in switchstart fluorescent fittings.
  
  
• High pressure sodium lighting is preferential in warehouses and factories.
  
  
• Use high frequency ballasts where flurorescent lighting is necessary (this uses 20% less electricity than older types).
  
  

Manual Control

Lighting efficiency can be achieved through:

• Awareness posters
  
  
• Awareness training sessions
  
  
• Leaflets
  
  
• Company policy
  
  
• Including energy management in supervisor's job descriptions.
  
  

Relamping

• Lamps should be changed in groups at specified intervals. They should be changed when their output has decreased by 30% (a light meter can be used to measure this).
  
  

Office Equipment

• Newer equipment is likely to be more efficient - when purchasing new equipment, energy consumption is now often given for many brands - this should be compared.
  
  
• All equipment should be switched off when not in use.
