Maintain projection performance with a replacement lamp engineered for compatible Boxlight, Christie, Eiki, and InFocus systems. The Battery Technology POA-LMP47-BTI gives IT and AV teams a practical path to restore image output when the original lamp reaches end of life. Instead of retiring a working projector, this replacement helps extend the service life of installed hardware and protect prior capital investment. For classrooms, conference rooms, and shared meeting spaces, lamp replacement is often the difference between a projector that stays in rotation and one that creates downtime. This model is intended for organizations that need a direct-fit replacement strategy with predictable maintenance planning. It supports a lower total cost of ownership than full projector replacement while keeping the installed base productive. Use it when brightness has faded, startup reliability has declined, or scheduled maintenance calls for a lamp swap. For teams managing multiple rooms, having the correct replacement lamp on hand reduces disruption and keeps critical presentations moving.
