Keep critical presentation spaces online with a replacement lamp matched to Optoma projector platforms that see regular business use. The BTI BL-FU310D-BTI uses a 310 W UHP light source to support the brightness these systems were designed to deliver, helping preserve image clarity for slides, video, and data-heavy content. For procurement teams and AV support staff, the value is in fit and continuity. This lamp is specified for Optoma EH490, EH504, EH504WIFI, EW504, SP.70B01GC01, W490, and W504 models, reducing the guesswork that can slow down maintenance windows. When a projector is part of a conference room, training center, or classroom schedule, a compatible replacement lamp is often the fastest path back to service. BTI’s replacement approach is aimed at organizations that want a practical, cost-conscious alternative to replacing the full projector. By replacing only the lamp assembly, you extend the useful life of installed hardware while keeping capital spend under control. The result is a cleaner maintenance cycle, less disruption for users, and a more predictable support plan for aging but still valuable projection assets.
