Keep legacy EIKI projection systems in service with a direct replacement lamp built for the PLC-XT20, PLC-XT25, and PLC-XT21. When a projector still meets the room’s needs, replacing the lamp is the fastest way to recover brightness and preserve the installed hardware investment. This BTI lamp is designed for organizations that need a practical, cost-controlled path back to usable image quality. It supports maintenance planning for classrooms, conference rooms, and fixed installations where downtime is more expensive than the part itself. By matching the original lamp requirement, it helps reduce the risk of compatibility issues that can come with generic substitutes. For IT and AV teams managing aging projection fleets, this is the kind of replacement that extends the life of a known-good system without forcing a full refresh. It is a focused purchase: replace the wear item, restore the image, and keep the room available for the next meeting or lesson.
