NOTE: You can order new lamp housings from www.infocus.com (in select 
areas), your retailer or your dealer. Use only a replacement lamp with the 
same type and rating as the original lamp. 
The part number is SP-LAMP-027.1

WARNINGS: 
 To avoid burns, allow the projector to cool for at least 45 minutes before 
you replace the lamp.
 Do not drop the lamp module. The glass may shatter and cause injury. 
Do not touch the glass lamp screen. Fingerprints can obscure projection 
sharpness.
 Be extremely careful when removing the lamp housing. In the unlikely 
event that the bulb ruptures, small glass fragments may be generated. 
The lamp housing is designed to contain these fragments, but use cau-
tion when removing the lamp housing. Before replacing the lamp, clean 
the lamp compartment and dispose of cleaning materials. Wash hands 
after lamp replacement. This product has a lamp which contains a very 
small amount of mercury. Dispose of it as required by local, state or fed-
eral ordinances and regulations. For more information see
