Maintaining the R-LS-1
Replacing the Bulb in the R-LS-1
Before you replace the bulb in the R-LS-1, you must first remove the R-LS-1 from the rack it is installed in. See
the Removing the R-LS-1 from a Rack section before continuing.
Follow the steps below to replace the bulb in the R-LS-1:
1. Obtain the appropriate replacement bulb. The LS-1-B is a 900-hour bulb, and the LS-1-LL-B is a 10,000-
hour bulb.
2. Turn off the R-LS-1 and remove the power input from the rear of the lamp. Allow the lamp to cool.
3. Make a note the location of the four Phillips screws on the bottom of the R-LS-1. You must return these
screws to this exact position when reconnecting the R-LS-1.
4. Loosen the four Phillips screws on the bottom of the R-LS-1. These screws hold the blue anodized bulb
housing in place on the R-LS-1 card.
5. Slide the R-LS-1 in place on the card until the recessed silver Allen screw is visible under the blue
anodized bulb housing on the bottom of the R-LS-1 card.
6. Use the Allen wrench included with the R-LS-1 to loosen the small silver screw. It is not necessary to
remove this screw completely.
7. Slide the silver lamp tube out of the blue anodized bulb housing.
8. Detach the black wire from the silver bulb and dispose of the old bulb.
9. Plug the new bulb into the socket on the black wire.
10. Slide the silver bulb into the bulb housing on the front of the R-LS-1. Ensure that it is fully inserted.
11. Tighten the setscrew on the bottom of the R-LS-1.
12. Tighten the four Phillips screws on the bottom of the R-LS-1
You have now properly replaced the bulb in the R-LS-1.
