ET-LAD7 is a bare replacement lamp shared across two brands: NEC's LT140, LT84 and LT84G, and Panasonic's PT-L7. NEC has also listed the same part as LT40LP. As a bare lamp, this is the bulb alone, without a housing, intended for projectors whose existing housing is still in good condition.
Because this is a bare lamp, fitting it means opening your existing housing and transferring the new bulb into the same frame, rather than swapping in a complete unit. It fits whether your projector is badged NEC LT140, LT84, LT84G, or Panasonic PT-L7, since all four share this lamp under the codes ET-LAD7 and LT40LP. Handle the bulb by its base and let it cool before removing it.

Common questions
Does the same lamp really fit both an NEC and a Panasonic projector?
Yes. NEC's LT140, LT84 and LT84G and Panasonic's PT-L7 all take this lamp, listed here as ET-LAD7 and also known as LT40LP. It's one of the cases where two brands used the same bulb.
Is ET-LAD7 a bare bulb or does it include a housing?
It's the bare lamp only, with no housing. You transfer the bulb into your projector's existing housing frame rather than fitting a new one, whether that projector is an NEC or a Panasonic model.
What's the difference between ET-LAD7 and LT40LP?
Nothing in terms of the part itself; they're the same lamp under NEC's and the wider trade's different naming. Either code correctly identifies this bulb for the LT140, LT84, LT84G or PT-L7.
Is there a lamp life figure for ET-LAD7?
No figure is published for this part, so we haven't stated one. Your projector's own hour counter, where fitted, is the best guide to when a replacement is due.
Any precautions when fitting a bare lamp like this one?
Let the old lamp cool fully before removing it, and avoid touching the new bulb's glass with bare fingers, since oils from skin can shorten its life. Handle it by the base or ceramic housing edge instead.
