Keep legacy projection systems in service with a replacement lamp built for exact-fit compatibility. The BTI BL-FS220B-BTI is designed for Optoma TW1692, TX7155, and TX7156, while also matching a wider set of supported models across Optoma, 3M, LG, and Vivitek platforms. For IT teams maintaining installed projector fleets, the value is straightforward: replace the lamp, preserve the projector, and avoid a full hardware refresh. That matters when the display system is tied to conference rooms, classrooms, or shared presentation spaces where downtime is visible and costly. This lamp is positioned as a practical service part for organizations that need consistent replacement coverage for aging projection assets. Use it to keep image output available, extend the useful life of existing equipment, and maintain continuity across rooms that were standardized on these projector families. When the projector itself still meets the room’s needs, a verified replacement lamp is the most efficient path back to service. BTI’s compatibility focus makes this part a strong fit for teams that value predictable maintenance and controlled replacement costs.
