UNSPSC 39112306: Iris diaphragm

UNSPSC 39112306 Iris diaphragm is a Commodity code that captures state and local procurement of specialized optical and lighting control components used in theatrical, entertainment, and infrastructure applications. Recent solicitations show that state and local governments purchase iris diaphragm systems primarily as components within broader lighting infrastructure projects — including theatrical spotlights for performance venues, traffic signal modernization systems, and specialty architectural and display lighting installations. Issuing bodies span a broad range: municipalities (City of Orlando, City of Brownsville, City of Cooper City, City of St. Petersburg), county authorities (Cameron County, Santa Clara County, Lee County), state agencies (State of Illinois through the Abraham Lincoln Presidential Library and Museum), school districts (Harlingen Consolidated Independent School District), and transit authorities (Trinity Metro in Fort Worth). No single issuing body dominates recent activity; opportunities are distributed across different jurisdictions and facility types, reflecting fragmented demand.

Recent activity concentrates in Texas, Florida, and Illinois. Representative current solicitations include the City of Orlando's IFB for Kia Center spotlights (ten Lycian Model 1295 ELT fixtures with xenon lamps and long throw lenses, due March 12, 2026), the State of Illinois Abraham Lincoln Presidential Library and Museum's IFB for ETC track lighting equipment including Irideon and Selador track-mount fixtures with Mosaic control systems for the Citizen City exhibit (due May 28, 2026), the City of Brownsville's IFB for traffic signal modernization including advanced detection systems and GPS time synchronization at 33 signalized intersections (due May 21, 2026), and Cameron County's IFB for traffic signal improvements under the Light Synchronization Project (due July 28, 2026). The code also covers commodity purchases of specialty components such as ADB Safegate airfield lighting fixtures through sole-source procurement by the Lee County Port Authority. Most recent opportunities specify performance requirements and manufacturer models rather than generic iris diaphragm components alone, suggesting that while the code technically captures these systems, actual procurement centers on integrated lighting assemblies where the iris diaphragm functions as a subcomponent of larger equipment packages.
