HP SB21 projector lamp
The HP SB21 takes lamp L1515A . It is available both as a complete module (bulb fitted in its housing) and as a bare bulb for re-using your existing housing.
The code printed on your old lamp or its housing should match one of the codes listed above. HP and third-party suppliers sell the same lamp under several numbers.
The model number is on a label on the base or rear of the projector, and in the on-screen menu under Information. Still unsure? Send a photo of the old lamp and we'll confirm the match.
Which lamp does the HP SB21 take?
The HP SB21 uses L1515A.
Should I buy the bare bulb or the module?
Both are available. The module is the bulb already fitted in its housing and is the quicker swap. The bare bulb is cheaper and re-uses your existing housing, but you move the bulb across yourself.
How long does the SB21 lamp last?
Rated life depends on the lamp mode you run and how the projector is ventilated; the lamp's own page lists the figure where the manufacturer publishes one.
Does the same lamp fit other HP projectors?
We don't list another HP model that shares this lamp.
