Lamp and housing module

This replacement lamp and housing module is built for 3M projectors that use part number 78-6969-9946-1. It arrives as a complete assembly so the installer does not need to handle a bare bulb. The unit is supplied new and carries a 90 day warranty from the manufacturer.

Direct projector lamp swap

The module replaces the original lamp and housing in a single step without reusing the old cage. The jump is worth it when the existing lamp has reached its rated hours or when brightness has dropped below usable levels. No additional parts are required for the changeover.

3M projector owners needing a ready-to-fit unit

This suits operators who want a guaranteed fit for the listed 3M models and prefer a housed lamp over a bare bulb. Buyers who need a different part code or a bare lamp without housing should look at something else.

Questions about this item

Will the 78-6969-9946-1-A lamp and housing assembly fit inside my 3M projector without modification?

The module is built as a direct-fit lamp and housing for the listed 3M projectors, so it matches the original mounting points and dimensions.

What is the installation step that users most often miss when fitting the 78-6969-9946-1-A?

After sliding the housing into the projector, the retaining screw or latch must be fully secured before the lamp door is closed, otherwise the safety interlock prevents startup.

When will the 78-6969-9946-1-A need to be replaced again?

Replace the lamp module when the projector's lamp-hour counter reaches its limit or when brightness drops noticeably; the unit carries a 90-day warranty from purchase.
