ERA 500 Hybrid IP Safety and Installation Manual
To reduce the risk of explosion, replace the lamp before it reaches the limit of its service life. Do not exceed
the lamp’s service life.
Replace the lamp immediately if it is deformed or in any way defective.
For maximum service life:
• Do not power the lamp off until it has warmed up for at least 5 minutes.
• Avoid short lamp power cycles wherever possible – use the fixture’s dimmer if light output is not required
for a short period.
• Before shutting down power completely, douse the lamp but leave power applied for a few minutes so that
cooling fans can prevent any momentary lamp temperature increase caused by heat from surrounding
components.
Lamp replacement
Warning! Read “Lamp safety” on page 5 before replacing the lamp.
Wear safety glasses and gloves when handling lamps. The lamp bulb is integral with the reflector.
Do not try to separate the bulb from the reflector. Install only a lamp that is approved by Martin for
the ERA 500 Hybrid IP or you may cause damage or create a safety hazard.
Replacement lamps are available from Martin (see “Spare parts” on page 26).
The lamp bulb and reflector must be perfectly clean when you install the lamp. Do not touch them 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.
Avoid internal condensation by replacing the lamp in dry conditions (relative humidity <50%) only. If this is
not possible, use the de-humidifying procedure described in “Dehumidifying the fixture” on page 15 after
replacing and adjusting the lamp.
To replace the lamp:
1. If the fixture has been in use, douse the
lamp but leave power applied for at least
30 minutes so that cooling fans continue
to run and reduce fixture temperature
evenly.
2. Disconnect the fixture from power. Make
sure that power cannot be reconnected
while you are working on the fixture.
3. Tilt the head so that the front lens is
pointing towards the control panel side
of the base.
4. See Figure 10. Release the four Torx 20
rear cover screws (arrowed) and lift the
rear cover away from the fixture slightly.
