Replacing Lamps - X-Rite SpectraLight III Operation Manual

Replacing Lamps

Replace burned out lamps immediately in order to maintain the overall performance standards of the fixture. We
recommend replacing lamps in complete sets. For example, if one daylight lamp burns out, replace both of them. Refer to
"Parts List" later in this document.
Simulated Daylight
Allow time for the daylight filters or incandescent lamps to cool before handling them. Always
use lens paper or equivalent when handling the lamps. Skin oils interfere with their performance.
1. Turn off the Main Power Switch before proceeding.
2. For booth installations, remove the front panel.
3. Release the front diffuser latch. Lower the front of the diffuser to its opened position (vertical).
4. Unscrew the quarter-turn fastener (see Figure 14.) and lower the diffuser. Slide the filter packs sideways to remove
them.
Note: Take special care to remove the filter packs. Improper handling during removal or replacement may result in
breakage.
5. Push one end of the lamp into the spring loaded socket with pressure to release the other end from its socket.
6. Lift the lamp clear of both sockets and discard in an appropriate receptacle.
7. Using a piece of lens paper (or equivalent) placed between your thumb and forefinger; insert the replacement lamp
into the sockets. Refer to Figure 15.
8. After the lamp has been replaced, replace the filter packs and secure them in place.
9. Reset the lamp time meter using the procedure "Resetting the Lamp Time Meter" on the following pages.
