Common questions
Is SP-LAMP-009 the same lamp as 31P9870?
Yes, SP-LAMP-009 is one of several alternative codes for this identical bulb. This particular listing supplies it bare; a separate module listing under SP-LAMP-009 includes the housing as well.
Does 31P9870 fit the Toshiba TDP-MT101?
Yes, the Toshiba TDP-MT101 is listed as compatible, alongside the closely related TDP-MT100. Both models share the same lamp requirement despite the different final digit in their model numbers.
Why does Knoll Systems use a different code prefix?
Knoll Systems rebadged this same lamp under its own catalogue naming, printing 'Systems' ahead of codes such as SP-LAMP-009 or TLP-LMT10 in its own documentation. The underlying bulb is unchanged.
What does TLP-LMT10 refer to?
TLP-LMT10 is Toshiba's alternative reference for this same lamp, used for the TDP-MT100 and TDP-MT101 models. If that code is printed on your old bulb, this listing matches it.
How should I dispose of the old lamp once replaced?
Take the old bulb to a suitable electrical or bulb recycling point rather than putting it in general waste, and avoid crushing it, as projector lamps can retain internal pressure even after use.
This is a bare lamp — the bulb only. You reuse the housing already fitted in your projector.
