Panasonic's DS20K2, DW17K2, DZ16K2 and DZ21K2 large-venue projectors, including their U variants, run four lamps together rather than one or two, and the ET-LAD520F (Quad Lamp) is the module fitted to each of those four bays. No wattage or hours figures are published for this part.
With a quad-lamp system, check how many of the four lamps actually need replacing before ordering, since this listing covers one module for one bay rather than a full set. ET-LAD520F (Quad Lamp) is the only code we hold for it. Being a module, each one drops into its bay complete with housing, without needing parts transferred from the old unit.

Common questions
What does a four-lamp, or 'Quad Lamp', system mean for maintenance?
The DS20K2, DW17K2, DZ16K2 and DZ21K2 run four lamps simultaneously, which keeps brightness high and means the projector can typically stay running if one lamp fails. Each bay takes its own ET-LAD520F (Quad Lamp) module, so replacement can be done one lamp at a time.
Do I need to order all four lamps at once?
Not necessarily. This listing is for a single ET-LAD520F module covering one of the four bays, so order as many as the number of lamps you actually need to replace.
Which projectors use this quad-lamp module?
The Panasonic DS20K2, DW17K2, DW17K2U, DZ16K2, DZ16K2U, DZ21K2 and DZ21K2U all share the same ET-LAD520F (Quad Lamp) module across their four lamp bays, so the same part covers any of these seven large-venue models.
Is there a way to tell which of the four lamps has failed?
That's read from the projector's own status or lamp menu, which will typically flag the specific bay. Once identified, the same ET-LAD520F module fits any of the four positions.
Does this arrive as a bare bulb or a complete module?
As a complete module, housing included, ready to fit directly into the relevant lamp bay. There is no bare-bulb option listed for this particular part.
This is a complete module — bulb already seated in its housing, so it drops straight in.
