DT00331 supplies the bulb only for the same twenty projectors covered by the housed module version of this lamp, spanning Hitachi's CP-S310 and CP-X320 series, 3M's MP8647 and MP8720, Boxlight, Dukane, Elmo, Liesegang and Viewsonic models. It runs at 160 watts with a 2,000-hour rating.
The same lamp is also sold complete with a new housing under the code 78-6969-9260-7, along with the further alternative numbers RLC-160-03A and ZU0270044010. Choose this bare option only if the cage inside your projector is undamaged, since nothing here replaces the housing, reflector or lens.

Common questions
How is this different from the 78-6969-9260-7 listing?
They are the same lamp, but 78-6969-9260-7 is the complete module with a new housing, while DT00331 here is the bulb on its own. Choose the bare bulb if your current housing is still in good condition.
Which Elmo model uses DT00331?
The Elmo EDP-X20 takes this lamp, sharing it with a wider family of Hitachi CP-S310 and CP-X320 series projectors built on the same optical platform during this period.
Do I need any special tools to fit a bare bulb?
Usually just a small screwdriver for the housing's retaining screws. Let the projector cool, open the existing cage, remove the old bulb, and seat the new DT00331 bulb the same way before closing everything back up.
What does RLC-160-03A refer to?
It is an alternative code for this same DT00331 lamp, alongside 78-6969-9260-7 and ZU0270044010. Different resellers have used different numbering for the identical bulb over the years.
Is it risky to touch the glass on a new bulb?
Yes, skin oils can create hot spots on the glass once the lamp is running, shortening its life. Hold the new DT00331 bulb by its base or ceramic housing rather than the glass envelope when fitting it.
This is a bare lamp — the bulb only. You reuse the housing already fitted in your projector.
