3M's DX70i projector uses a single lamp, listed under part 78-6969-9994-1, supplied here complete with its housing. At 300 watts and a 2000-hour rated life, this is a full module rather than a bare bulb, so it drops in as a direct swap for the original unit without any transfer of parts between housings.
This same lamp is also stocked separately as a bare bulb under code WDX70i, for anyone who wants to reuse an existing housing rather than replace it. If your old module still turns and mounts correctly, the bare-bulb route can be cheaper; if the housing is cracked or the socket is damaged, order this module instead.

Common questions
Which projector does 78-6969-9994-1 fit?
This lamp module is built for the 3M DX70i. It is the only projector listed against this part code, so if your unit is a DX70i this is the correct complete module, with lamp and housing supplied together.
What is the difference between this and the WDX70i listing?
WDX70i is the same lamp sold as a bare bulb without a housing, for fitting into a module you already own. This listing, 78-6969-9994-1, includes the housing as well, so choose it if your existing module is damaged or missing.
How do I reset the lamp timer after fitting a new module?
Most 3M projectors reset the lamp-hour counter automatically once a new module is detected, or offer a manual reset in the on-screen service or lamp menu. Check your DX70i's user manual for the exact menu path, since firmware versions vary.
Is this a genuine 3M part?
Yes, 78-6969-9994-1 is the manufacturer part code for this lamp module. We list it under the same code 3M uses, along with the WDX70i bare-bulb equivalent, so you can cross-check whichever number appears on your existing unit.
What should I check before fitting the module myself?
Let the projector cool fully, unplug it, and remove the lamp access panel with the projector powered off. Handle the module by its frame rather than the glass, and make sure it clicks fully into its seated position before closing the panel and powering back on.
This is a complete module — bulb already seated in its housing, so it drops straight in.
