Used CTT/DAX projection lamp in good condition. Inside top of bulb has sooty deposit, however this doesn't seem to affect it's operation (see photos)
This was removed from a working projector and carefully stored. Tested and is in good working condition, however we do not guarantee the length of life left in the bulb. No returns. [TGP21]
Tip: To extend lamp life, run the projector's cooling fan for 5-10 minutes after the bulb is turned "off". Do not bump or shake the projector while the bulb is lighted.
