Keep legacy Optoma projection systems in service with a replacement lamp built around the original fit and optical profile. BTI BL-FS180B-OE is designed for the S22E and DS306, making it a practical choice when you need to recover brightness without replacing the projector itself. For IT teams and AV buyers, lamp replacement is about more than restoring light output. It is about preserving installed infrastructure, avoiding disruption, and extending the useful life of equipment already approved for the room. An OEM bulb helps maintain the expected performance envelope of the projector, which matters in classrooms, conference spaces, and shared presentation environments where consistency is non-negotiable. This lamp is a strong fit for organizations that value exact compatibility and predictable service intervals over lower-grade substitutes. When a projector is still mechanically sound, replacing the lamp is often the most cost-effective path to keep the asset productive. BTI’s OEM-bulb approach supports that decision with a replacement built for the specified Optoma models.
