Lamp life
Monitor lamp hours using the resettable LAMP ON TIME counter in the INFORMATION control menu. To
reduce the risk of explosion, replace the lamp when it reaches the limit of its average service life, i.e. when
usage reaches 750 hours. Never exceed the lamp’s average service life by more than 10%. Replace the
lamp immediately if it is deformed or in any way defective.
For maximum service life, avoid powering the lamp off until it has warmed up for at least 5 minutes.
Lamp replacement
Warning! Wear safety glasses and gloves when handling lamps. The clear lamp bulb is integral with
the ceramic lamp base. Do not try to separate the bulb from the base.
Important! The lamp can be a stiff fit in its holder. Twist the lamp base a full 45° clockwise when
installing to ensure that the lamp contacts are fully engaged.
Replacement lamps are available from Martin™ by ordering P/N 97010346.
The clear bulb must be perfectly clean. Do not touch it with your fingers. Clean the lamp with an alcohol
wipe and polish it with a clean, dry lint-free cloth before installing, particularly if you accidentally touch the
bulb.
To replace the lamp:
1. Disconnect the fixture from power and allow it to cool
for at least 30 minutes.
2. Tilt the head so that the text around the lamp access
cover is facing the right way up and the cover is easy
to reach.
3. See Figure 8. Release the Torx 20 cover screw A
and open the cover.
4. See Figure 10. Grasp the ceramic lamp
base, twist it 45° counterclockwise to
release it, then remove the lamp gently from
the fixture.
5. See Figure 10. Hold the replacement lamp
so that the external wire B is facing up
towards the top of the head (towards the
vertical and horizontal alignment screws C
and D) and line up the contacts on the lamp
base with the slots in the lampholder. Slide
the lamp into the fixture until the contacts
are fully engaged in the slots, then twist the
lamp base a full 45° clockwise until it locks
into position with a noticeable click. The
lamp is a stiff fit and trying to strike a lamp
that is not correctly installed can cause
damage that is not covered by the product
warranty, so ensure that the lamp is
correctly locked into position.
