Eiki 5811118436-SEK 310W Replacement Projector Lamp

The 5811118436-SEK is the Eiki replacement projection lamp for the EK-402U, EK-401W, EIP-4600W, EK-400X, and EIP-X5500. It is a 310-watt UHP lamp module that brings a dimmed projector back to its rated output.

Using the specified lamp keeps the picture bright and evenly lit and avoids the color shift a mismatched bulb can introduce. Keeping one on the shelf means a quick swap the moment the on-screen lamp warning appears.
