Most everyday light bulbs are straightforward to replace, but it is still worth taking a calm, safety-first approach. The aim is to change the bulb without damaging the fitting, standing unsafely, or ignoring signs that the problem is really electrical.
If the fitting looks damaged, feels loose, shows scorch marks, smells of burning, buzzes, sparks, gets wet, or trips the electrics, stop and report it to 2let2 instead of trying to fix it yourself.
Before you start
Switch the light off at the wall and give the old bulb time to cool before touching it. If the light is controlled by more than one switch, make sure nobody else turns it back on while you are working.
Use a stable step ladder if the fitting is above comfortable reach. Do not stand on chairs, beds, boxes or worktops. Keep your hands dry and clear the floor around you so you are not twisting or balancing awkwardly.
Check the old bulb and fitting before buying a replacement. Match the cap type, shape and rating shown on the fitting or old bulb. Common fittings include bayonet caps and screw caps, but do not force a bulb if it does not fit easily.
Changing the bulb
Remove the old bulb gently. For a bayonet bulb, press it in slightly and turn it anti-clockwise. For a screw bulb, turn it anti-clockwise until it comes free. Hold the bulb by the base or body, not by fragile glass.
Fit the new bulb without forcing it. Bayonet bulbs should line up with the slots, press in and turn clockwise. Screw bulbs should turn smoothly into place. Once fitted, step down safely before switching the light back on.
Use LED bulbs where suitable. They run cooler, use less energy and usually last longer than older-style bulbs. Keep the packaging or note the bulb type so the next replacement is easier.
When to report it
If the new bulb does not work, try one known working bulb in the same fitting only if it is safe to do so. If neither bulb works, the issue may be the fitting, switch, circuit or appliance rather than the bulb.
Report the issue to 2let2 if the fitting is cracked, loose, discoloured, buzzing, sparking, damp, unusually hot, or if changing the bulb causes the electrics to trip. Do not remove the fitting, open switches, touch exposed wiring or attempt electrical repairs.
For broken bulbs, switch the light off and avoid touching fragments with bare hands. Clear the area carefully, ventilate the room if needed, and report anything stuck in the fitting rather than trying to dig it out.
