Keep a Panasonic PT-D3500U projector in service without replacing the full unit. This BTI replacement lamp is specified at 300 W and uses UHM lamp technology to support the output profile this platform was built around. For facilities that depend on scheduled presentations, training rooms, and fixed-install projection, a correct lamp replacement is the fastest path back to usable brightness. BTI manufactures this lamp as a direct replacement for the Panasonic PT-D3500U, helping reduce compatibility risk during procurement and maintenance. The lamp is backed by a 6-month limited warranty, which adds a practical layer of coverage for replacement planning. When projector performance starts to fade, replacing the lamp preserves the installed display system and avoids the cost and disruption of a full projector refresh. This part is suited to IT and AV teams that need a dependable service component for an existing Panasonic installation. It is a focused, model-specific replacement designed to keep the projector aligned with its original operating intent.
