Common questions
What is DMS800LK?
DMS800LK is an alternative code for the same lamp and module as 78-6969-9880-2. If your old lamp carries either label, this listing is the correct replacement for your 3M Digital Media System projector.
Does this listing include the housing, or is it a bare bulb?
This is a full lamp with module. The bulb is already fitted inside its housing, so you replace the entire unit as one piece rather than swapping just the bulb inside your existing cage.
Which Digital Media System models does this lamp fit?
It covers the 3M Digital Media System 800, 810, 815, 865 and 878. These models share very similar names, so check your projector's exact number before ordering to be sure you order the right one.
What are the wattage and rated hours for this lamp?
This lamp is rated at 230W with a 2000-hour lamp life. As with any projector bulb, actual life depends on usage patterns and operating conditions, so treat the figure as a guide.
How do I know it's time to replace this lamp?
Look out for a dimmer or discoloured picture, an on-screen lamp warning, or the projector failing to power on properly. These signs typically appear as the lamp approaches the end of its rated 2000-hour life.
