This listing is for an energy saving bulb that can be used to replace 118mm halogen stick bulbs. It requires 110 volts which is the usual voltage for outside site lamps (such as the unit shown in the photographs). It will not work with 240 volt lighting.
The bulb is suitable for use with most photocell and PIR units that use 110 volts. This bulb require a clearance of at least 60mm between the axis of the connectors and the front cover of the lamp compartment. It uses 24 Watts of power to produce a similar amount of light to a 100 or 150 watt halogen bulb. Not only will it use considerably less power but it will also last longer than traditional halogen stick bulbs.
UK shipping will be £2.80 for the first bulb purchased plus 1p for each additional bulb purchased at the same time.
This is for 110 volt lighting units (such as the one photographed). It will not work with 240 volt lighting units.
