The '(Single Lamp)' tag on the part number confirms this is for the single-lamp configuration of the D4000 chassis. No wattage or lamp-life figures have been published for this part.\u003c\/p\u003e\u003cp\u003eWe list two alternative codes for this lamp, ET-LAD40 (Single Lamp) and ET-LAD40A (Single Lamp), so check your old lamp's label against either if you are confirming a match. As a module, it replaces the housing along with the bulb, fitting the bay as one piece. Confirm the '(Single Lamp)' designation applies to your unit before ordering.\u003c\/p\u003e\u003ch3\u003eAt a glance\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e — Projector Lamp with Module\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSKU\u003c\/strong\u003e — LA-09869\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility\u003c\/strong\u003e — 3 projector models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCommon questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat's the difference between ET-LAD40 and ET-LAD40A?\u003c\/strong\u003e\u003cbr\u003eBoth appear in our records as references for the same lamp fitted to the PT-D4000 and PT-D4000E.
