This bare bulb, code ET-LAD7700LW, is the long-life option for Panasonic's D7700 and DW7000/DW7700 projectors, listed here across ten Long Life variants including the PT-D7700C-K, PT-DW7000EK and PT-LW7700. It supplies the burner only, for fitting into a housing that is already in place and working.
These D7700 and DW7000/7700 models were also sold in dual-lamp and single-lamp configurations under related codes, so it is worth confirming that Long Life specifically is what's printed on your existing lamp before ordering — the wrong variant from the same family will not seat or run correctly even though the projector looks identical.

Common questions
What does 'Long Life' mean for this lamp?
It marks this as the extended-life variant of the lamp fitted to Panasonic's D7700 and DW7000/DW7700 projectors, distinct from the dual-lamp and single-lamp codes sold for the same chassis, so it's worth matching the exact designation on your old lamp.
How is this different from the dual-lamp or single-lamp version for the same projector?
Panasonic sold these D7700 and DW7000/7700 models in several lamp configurations, including dual and single-lamp setups, each under its own code. This listing, ET-LAD7700LW, is specifically the Long Life bare bulb, so check which designation is printed on your unit.
Is this the bulb only or does it come with housing?
This is a bare lamp: the burner and base connector, without the surrounding cage. It's intended for a Long Life housing that's still in working order and simply needs a fresh bulb fitted.
Which Panasonic projectors take the ET-LAD7700LW?
It's listed against ten Long Life variants of the D7700 and DW7000/DW7700 range, including the PT-D7700C-K, PT-DW7000EK, PT-DW7700K, PT-DW7700L, PT-L7700 and PT-LW7700, among others sharing the same lamp bay.
How should I handle the bulb once it's out of the box?
Keep the ET-LAD7700LW by its base rather than the glass, and let the projector cool down fully before opening the lamp compartment, since fingerprints on the envelope or fitting it while warm can shorten how long it runs.
This is a bare lamp — the bulb only. You reuse the housing already fitted in your projector.
