Lamp Replacement - Martin MAC 250 Wash User Manual

Lamp replacement

Lamp life will vary. The rated life of a lamp is the average operating life before lamp failure in the
manufacturer's test cycle. To reduce the risk of lamp explosion that will almost certainly damage the fixture,
replace the lamp when it reaches the limit of its rated life. Never exceed a long-life lamp's rated life (3000
hours for the Philips MSD 250/2) by more than 10 percent.
For maximum lamp life, avoid excessive strikes and always allow the lamp to burn for at least 5 minutes
before dousing it.
Replace the lamp when:
• it strikes with difficulty or not at all, is visibly deformed or is in any other way defective
• hours of use reach the manufacturer's "replace before" limit. See Table 3.

Danger! Intense heat. Avoid contact by persons and materials. The exterior of the fixture can get
very hot – up to 160° C (320° F). When replacing the lamp, disconnect the fixture from AC
power and allow it to cool for at least 45 minutes before proceeding. Protect eyes and
hands with safety goggles and gloves.
1. Locate the lamp access cover at the back of the fixture head and remove the two Phillips screws.
2. Pull out the lamp socket.
3. If changing the lamp, remove the old lamp from the socket.
4. Holding the new lamp by its ceramic base (do not touch the glass), align the small pins on the lamp with
the small holes in the socket and insert the lamp squarely. Make sure that the 4 small projections on the
base contact the face of the socket.
5. Clean the glass bulb with the cloth supplied with the lamp, particularly if your fingers touched the glass.
A clean, lint-free cloth wetted with alcohol may also be used.
6. Insert the lamp into the fixture with as little twist in the lamp wires as possible.
