REMOVING A BROKEN BULB
Flow you go about this job depends on how much of the bulb is broken and the type of socket it is fitted to. So be prepared to improvise. Basically, what you have to do is push the cap of the bulb against the spring pins in the lamp holder, rotate it to clear the fixing cups and then pull it free.
1. First, turn off the light switch and the power to the circuit.
Alternatively, cover the broken bulb with a thick polythene bag and tap away the remaining glass, including the centre spindle carrying the filaments. The bag will stop splinters flying into the air.
2. Unscrew the skirt from round the socket to expose enough of the metal cap of the bulb for you to grip in a gloved hand. If this proves awkward, push pliers into the end of the cap to depress and rotate it. Open the jaws a little as you do this so the outside edges make contact with the inside of the cap.
If you are unsure whether a fuse in a plug has blown or the appliance it serves is at fault, you can check the fuse using a metal-cased torch.
1. First check that the torch is working, then hold it upside down and unscrew the bottom cap to expose the base of the batteries.
Put the torch in the on position and hold the fuse so that one end touches the battery and the other the metal casing. If the torch lights (ie, the fuse completes the circuit), you’ll know that the fuse is in working order.
BOWL LIGHT FITTINGS
There are various types of bowl light fittings which fully, or partially, encompass the bulb. 1. Many modern decorative bowl fittings are suspended from a single chain. To release the bowl look for the screws on the side of the metal cup into which the rim is inserted. When done up, these screws locate under the lip of the rim. Undoing them will allow the bowl to drop down. The procedure is trickier than it sounds because you need one hand to support the bowl and the other to turn the screws. So there’s no free hand to steady yourself, say, if you’re working over a stairwell. Therefore, slacken all the screws first with a screwdriver, so you can undo them fully later with your fingers.
If there’s any risk of the bowl slipping free without warning, tape it securely to the fitting to stop it dropping.
Another type of fitting also encloses the bulb, but can be close mounted either to a wall or, more usually, on a ceiling.
2.There are some elaborate fixings which invisibly hold the bowl in place. One type, for example, has a metal backplate which acts as a base for the lampholder. The bowl fits over the plate and then a lever is activated to move catches under the rim to keep it in place.
To remove the bowl, at ceiling level you should be able to see the slightly bent end of the recessed lever. Pull this out towards you. Push the bowl upwards to clear the catches then push the lever round to retract the catches leaving you free to lower the bowl to expose the bulb.
