The main lamp supplied has a rated average life of 50 hours; however the actual life of the lamp will
depend on the intensity setting normally used. The highest setting is an over-run setting which
increases light output but will reduce lamp life to about 20 hours. Conversely, running the lamp at the
next lowest setting will produce a lamp life of about 60 hours. It is strongly recommended that the
lamp be replaced as a routine maintenance task, to reduce the possibility of failure during surgery.

1.
Always use protective gloves while replacing the lamp as lamp temperatures may be sufficiently
high to burn skin should it come into contact with the quartz capsule. Where possible, allow the
lamp to cool before replacing it. Ensure that the new lamp is free of grease or finger prints
before replacement. Any such marks should be removed with a solvent such as ethanol to avoid
reducing lamp life.
2.
First grip the lamp module located beneath the cable gland on the side of the lamphouse. Pull
the lamp module out to reveal the lamp.
3.
Grip the lamp at the side of the gold section where the rectangular cut-out is located, and pull
the lamp out of the lamp module.
Do not attempt to pull the lamp out by gripping the
quartz capsule.
4.
Push the new lamp into the lamp module so that the lamp flange sits flush on the front of the
gold tube section. Replace the lamp module in the socket in the lamphouse, so that the pins
‘click’ into place. Correct lamp replacement using this method is essential for ensuring good
illumination.
