Using the Filter Slot on the LS-1
The 3 mm slot between the lamp and the fiber coupler can be used to hold filters or light blocks. You can place a
filter in the filter slot, but you must heed the following warnings:
•
Filters must be 3 mm thick or less
•
Filters should not be plastic, as they may melt from the heat generated by the lamp
•
Filters should not be flammable materials, as they may ignite due to the lamp heat
•
Filters cannot be clamped in place, as there is no filter locking mechanism built into the lamp
Maintaining the LS-1
Replacing the Bulb in the LS-1
Follow the steps below to replace the bulb in the 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 LS-1 and remove the power input from the rear of the lamp. Allow the lamp to cool.
3. Use the included Allen wrench to loosen the setscrew on the bottom of the lamp. You do not need to
remove the setscrew.
This screw holds the bulb in place inside the LS-1.
4. Remove the two black hex bolts (located on either side of the silver On/Off switch) using a 3/32” Allen
wrench (not included). Keep these bolts nearby.
5. Separate the two halves of the LS-1 by gently pulling them apart. Ensure that you the wires of the LS-1
are not caught and that the unit separates easily.
6. Carefully remove the silver bulb from the housing in the front of the LS-1.
7. Detach the black wire from the silver bulb and dispose of the old bulb.
8. Plug the new bulb into the socket on the black wire.
9. Slide the silver bulb into the bulb housing on the front of the LS-1. Ensure that it is fully inserted.
10. Tighten the setscrew gently on the bottom of the LS-1.
11. Re-attach the two sides of the LS-1, ensuring that the lamp is fully connected.
Note: If you cannot fully reconnect the LS-1 due to the installed filter, you may need to gently move the
black capacitor in the rear half of the LS-1 out of the way until the halves properly connect.
12. Re-insert the two hex bolts and tighten.
You have now replaced the bulb in the LS-1.
