Changing light globes | |||
| Back | ||||
There are 2 light globe types: Make sure that the globe is cool before trying to change. |
BA - Bayonet base ('classic' in Australia) ES - Edison screw base (common in USA) Turn OFF the electricity. Switches are usually pushed UP to turn off in Australia but with interconnect switches, this cannot be relied on. |

Bayonet (BA) Base Globe Removal 1 - push in a small distance 2 - rotate anti-clockwise 3 - lift out To put in a new globe, push in gently and rotate clockwise. When the globe 'drops in' push in and rotate clockwise a small way until it will no longer rotate. WARNING: Corroded bases are sometimes hard to push in and rotate. If this is what you suspect get an experienced person to help. |

Edison Screw (ES) Base Globe Removal 1 - push in softly If it does not push in, start rotating 2 - Screw anti-clockwise 3 - lift out To put in a new globe, push in gently and rotate clockwise until it will no longer rotate. WARNING: Globes with Edison Screw bases may sometimes have poor contacts and will not light. Try rotating a little further so there is positive contact with the bottom contact. |

| Check the globe base type - Bayonet base (BA) or Edison Screw (ES) | ||
| What colour do you want? Natural (blue-ish) or Warm (more like a standard globe) | ||
| What shape to fit existing light fittings? There are both curly short and longer sizes | ||
| How many watts? |
As a rule-of-thumb, new globes use only 1/5th or 20% of the power of a standard globe, for the same amount of light. See table below. |

| These globes usually cost more to buy but last longer. Replacing a 100 watt globe with a 20 watt energy saver & using the globe 5 hours per night, saves around $20 per year in electricity costs in Australia, plus 280 tonnes of carbon dioxide greenhouse gas if generated from coal. (Gas is better - there is only an extra 84 tonnes of CO2 if a standard 100 watt globe is used.) |
