Way to Save Electricity

Lighting Devices

• Turn off the lights when not in use.

• Use the right bulbs in the right places.
• For areas that require a lot of brightness, fluorescent lamps is suitable for indoor lighting and sodium vapor lamps or mercury vapor lamps is suitable for outdoor lighting.
• Use a clear lamp cover if there are no glare problems and always keep it clean
• Consider using a desk lamp for tasks that require a single spot. 
• Unplug lighting devices when not in use for a long time.
• Use a reflector lamp instead of the lamp with opaque plastic cover.

• Use a fluorescent lamp or compact fluorescent lamp or LED lamp instead of incandescent lamps which instructions for use are as follows:
  - 18 watt and 36 watt thin shape fluorescent lamps have the same brightness as 20 watt and 40 watt fluorescent lamps and can be used interchangeably without changing ballast and starter.
  - There are two types of compact fluorescent lamp, built-in ballast type and pin-type. Built-in ballast type can be installed in an existing screw socket to replace incandescent lamp while pin-type requires a ballast and a socket that corresponds to their pin.
  - LED lamps use low electrical energy and provide light equal to fluorescent lamps and fluorescent lamps.

Electric Iron
