Keep Dell projection systems in service with a replacement lamp matched to the S500 family. BTI 331-1310-BTI is designed for Dell S500, S500wi, and S500 Ultra Short Throw projectors, making it a practical option when the projector chassis, optics, and mounting are still worth preserving. For infrastructure teams, the value is straightforward: replace the failed light source, restore the room, and avoid the cost and disruption of a full projector refresh. That matters in conference rooms and classrooms where the projector is part of a standardized deployment and downtime affects scheduled work. BTI’s replacement approach is especially useful for organizations that maintain older AV assets across multiple sites. Instead of sourcing a new projector and reworking the room, you can keep the original installation intact and return the space to service faster. It is a focused, procurement-friendly part for environments that still depend on Dell S500-series projection.
