Keep compatible Sony projectors in service with a replacement lamp built for direct-fit restoration. The Battery Technology LMP-C162-BTI is specified for the Sony CS20, CS20A, CX20, CX20A, ES3, ES4, EX3, EX4, and VPL-CS20, making it a practical choice when lamp output has faded and image quality is no longer meeting room standards.

It is about protecting meeting schedules, avoiding last-minute projector swaps, and extending the useful life of installed hardware. This lamp is intended for organizations that want a straightforward replacement path for supported Sony models without changing the projector platform. Choose this lamp when you need a service part that aligns with the original projector family and keeps the display system operational. It is a focused replacement component for environments where presentation reliability matters and downtime has a cost.
