Keep interactive presentation systems in service with a replacement lamp built for compatible Smart Board projectors. This BTI lamp is specified for a broad set of models, including 680i, 680i2, SB660, SB680, UF55, UF55W, ST230i, SBD685, SBD680, SBD660, SB685, and SB680i3. For support teams, that compatibility matters: it simplifies maintenance planning and helps reduce downtime when the original light source reaches end of life. At 55 W, this lamp is intended to restore the brightness needed for readable text, clear graphics, and reliable classroom visibility. It is a practical choice for organizations that want to preserve installed Smart Board projection hardware rather than replace the entire system. That makes it especially useful in schools, training rooms, and meeting spaces where the projector is part of a larger collaboration workflow. BTI’s replacement-lamp approach gives procurement teams a service part that fits the maintenance model of legacy projection deployments. When uptime, budget control, and compatibility all matter, replacing the lamp is often the most efficient path back to full operation. Keep one on hand as a spare, or use it to bring a dimming projector back to spec before it affects instruction or presentations.
