Common questions
Why do Infocus and Proxima both list a DP-8400X?
These two brands sold what appears to be the same projector design under their own names, and both share the 456-8935 lamp as a result. It is a common pattern in this era of business projector.
What is SP-LAMP-015?
SP-LAMP-015 is an alternative code for the identical 456-8935 bare lamp, used in some Infocus and Proxima documentation. It describes the same bulb as DT00591 and PRJ-RLC-011.
Is this lamp supplied with a housing?
No, this is a bare bulb, sold without a housing or cage. It is intended to be fitted inside the housing already built into your Hitachi, 3M, Dukane, Infocus, Liesegang, Proxima or Viewsonic projector.
How long should a 310-watt lamp like this last?
It carries a 2,000-hour rating at its full 310-watt output. Because it runs hotter than many lower-wattage lamps, keeping the projector's vents clear of dust can help it reach that expected life.
What is the safest way to remove the old bulb?
Switch off and unplug the projector and let it cool for at least thirty minutes, since a 310-watt lamp holds significant heat after use. Then handle the old bulb by its base rather than the glass.
This is a bare lamp — the bulb only. You reuse the housing already fitted in your projector.
