Restore projection performance without replacing the entire system. The BTI ET-LAV300-BTI is a 300 W replacement lamp designed for select Panasonic PT-VW series projectors, including PT-VW340, PT-VW340Z, PT-VW345N, PT-VW345NZ, and PT-VW350 models. For IT and AV teams managing installed projector fleets, lamp replacement is often the most efficient way to recover image quality and keep rooms available. This part supports that maintenance strategy with a specification set aligned to Panasonic compatibility requirements, helping reduce disruption when a lamp reaches end of life. Choosing the correct replacement lamp matters in high-use spaces where brightness, uptime, and predictable service intervals affect daily operations. The ET-LAV300-BTI gives procurement and support teams a direct replacement path for compatible Panasonic projectors, making it easier to maintain presentation standards while controlling lifecycle costs.
