The 456-8759 is a 200 watt module rated for 2000 hours, originally a Dukane part for the Image Pro 8759 but shared across a wider group of rebadged projectors. Ask sold it for the C170, C175 and C185, Infocus used it in the C170, C175, C185, IN32, IN34, LP600, W340 and W360, and Proxima carried it for the C175.
You may also see this lamp listed as SP-LAMP-019 or under Infocus's own code SP-LAMP-023, both of which describe the same 200 watt part we sell as 456-8759. Since Ask, Infocus and Proxima projectors from this era were built on shared designs, matching the model printed on your projector's case is more reliable than matching the brand name alone.
