Direct replacement lamp

The DynamicLamps ASK Proxima 420004500 Ushio module restores brightness to compatible ASK Proxima projectors. It fits models such as the C3255, C3305 and S3307 series without modification. Installers simply swap the old module and reset the lamp timer. The part number 420004500 matches the original manufacturer reference.

Cool running operation

The Ushio lamp operates at the thermal profile specified for the listed projectors. Fan noise remains at the level designed by the projector maker. Power draw matches the original module so the projector’s supply is not stressed. No extra cooling or voltage changes are required.

Drop-in fit for listed models

The module slides into the existing lamp cage of every model listed in the compatibility table. It frees the user from sourcing bare bulbs or separate housings. Projectors not listed — such as newer 4K or laser units — are not supported. The part replaces 10118002 and 737534549704 references directly.

Questions about this item

How do I install the lamp module and which step is often missed?

Power off the projector, unplug it, let it cool, remove the lamp cover, slide out the old module, insert the new 420004500 unit until it clicks, replace the cover, then reset the lamp timer in the menu.

What maintenance or replacement will this lamp need later?

The Ushio lamp inside the module is a consumable; when brightness drops or the projector signals end of life, replace the entire 420004500 module again.

What limit appears first during extended use of this lamp?

Light output gradually declines over the rated hours; the projector will warn you when the 420004500 module reaches its usable limit.
