1Turn Off The Power
Never attempt to change a light bulb with the power still connected. Remember, safety first!
2Allow The Bulb To Cool
Remember that incandescent light bulbs run very hot, so give them a chance to cool down before you start touching anything. Fortunately, you won't have this problem with LED light bulbs, as they produce very little or no heat.
3Use A Ladder
Generally speaking, light bulbs are found in hard-to-reach locations. This means it's probably a good idea to use a ladder to replace them.
4Remove The Old Bulb
The way you do this will depend on whether your bulb has a bayonet, screw or a push-and-twist fitting. For bayonet mounts, and for GU10-type fittings, hold the bulb lightly but firmly, and gently push upwards whilst turning it anticlockwise until it comes out of the socket. For screw fittings gently twist the bulb anticlockwise until it comes out.
5Insert The Replacement Bulb
Gently but firmly push the bulb into the socket and turn clockwise until you feel it lock into place.
6Dispose Of Your Old Bulb
Always dispose of old light bulbs responsibly.
