Maintain projection uptime with a replacement lamp built for a defined set of Optoma projector models. BTI BL-FP190E-BTI is the practical choice when you need to bring an installed system back online without replacing the entire projector. It is designed for compatibility with BR323, BR326, DH1008, DH1009, DS340E, DS345, DS346, and DX342 models. For IT and facilities teams, lamp replacement is often the most efficient way to preserve existing AV investments. This part supports that strategy by targeting the projector models already in the field, helping reduce compatibility uncertainty and keeping maintenance work predictable. Use it to restore presentation readiness in meeting rooms, training spaces, and classrooms where downtime is not an option. By replacing the light source instead of the full unit, you protect capital budgets while extending the useful life of installed Optoma hardware. It is a focused replacement part for organizations that value continuity, controlled spend, and straightforward maintenance planning.
