Fiducial Flashpole Product

UUR Lawrence Livermore National Laboratory June 1, 2026 UUR Page 1 Statement of Work: Fiducial Flashpole Product Subject This Statement of Work (SOW) defines the specific tasks, deliverables, schedule, and acceptance criteria for the assessment, design, development, prototyping, testing, and delivery of a new and improved fiducial flash system for Lawrence Livermore National Laboratory (LLNL). Background and Summary LLNL’s Independent Diagnostic Scoring System (LIDSS) team develops and deploys a fiducial flashpole on marine assets (rafts). These flashpoles emit a bright “flash” during photo capture to provide light beacon location markers on the collected photographs for size and location data analysis. Timing on everything is critical due to the nature of the high velocity subjects captured. The current flashpole (pictured below) has experienced reliability issues primarily related to environmental exposure and humidity ingress leading to electrical shorts and frequent field maintenance requirements. The existing design places the LiPo battery directly beneath the LED compartment inside the flashpole head. Therefore, removal for external charging creates a more significant point of environmental intrusion and its location at the top of the pole makes replacement and maintenance difficult for field personnel. -- 1 of 5 -- UUR Lawrence Livermore National Laboratory June 1, 2026 UUR Page 2 Product Requirements Optical Performance & Functionality 1. Flash brightness shall meet or exceed the current LLNL 432-LED flashpole system estimated at 500k lumens. The vendor must provide performance data showing the new proposed flashpole provides greater luminous output than the existing model. 2. Flash pulse timing shall operate at 1 Hz or less. Meaning flash ON duration of 50 ms or greater and an OFF duration of 950 ms or less. 3. Light output shall provide uniform 360° and upward visibility to ensure consistent detection by surrounding rafts and overhead drone imaging systems. 4. The flashpole shall accept an external trigger signal from onboard raft instrumentation (referred to as CORE) to initiate its flash. 5. The flashpole shall include an internal triggering capability through an integrated photodiode sensor to initiate its flash. Internal trigger requirements will be provided by LLNL. 6. The flashpole shall log internal trigger events, including timestamp and other LLNL- specified parameters. Logged data shall be stored on the flashpole and be accessible for field download. 7. (Optional) Ability to distinguish a set number of flashpoles from another by unique signature detectable from final captured images. Electrical & Firmware 8. The flashpole firmware shall either be fully modifiable by LLNL engineers or be supported by the manufacturer for bug fixes and future feature enhancements throughout the supported life of the product. -- 2 of 5 -- UUR Lawrence Livermore National Laboratory June 1, 2026 UUR Page 3 9. The flashpole shall support simple firmware updates and rollbacks, allowing LLNL personnel to install different firmware versions in the field without specialized equipment or factory service. 10. The flashpole shall support operation from either a dedicated onboard battery or a 24V onboard power bus. Compatibility with 12V and 48V power buses is strongly desired. 11. Electrical operation shall comply with applicable standard electronic safety practices or LLNL electrical safety requirements. Systems operating above 50V shall require approval through the LLNL AHJ Electrical Safety process or other certification (e.g. UL or ETL). Environmental Protection & Reliability Acceptance Criteria 12. The system shall be protected against saltwater splashes and temporary saltwater immersion through compliance with IP67 or an equivalent protection method (e.g., conformal coating) that provides comparable environmental protection. 13. The design shall operate at 100% relative humidity at 36°C (97°F). It will minimize or mitigate humidity intrusion to prevent corrosion, electrical shorts, and other environmental failures. 14. The flashpole shall operate within an external temperature range of -5 °C to 50 °C (23 °F to 122 °F). Power density and heat sinking need to be appropriate for expected higher temperatures in deployment conditions around the equator or desert environments. 15. UV exposure and environmental conditions shall not degrade electrical or mechanical performance for a minimum service life of 3 years without required repairs. 16. Sustained operation shall support continuous 1 Hz flashing without thermal runaway, battery degradation, or electronic damage for either (a) a minimum of 1 hour of continuous operation, or (b) a minimum of 5 minutes of continuous operation followed by automatic thermal shutdown and recovery. Reduced flash rates of up to once every 15 seconds are acceptable for thermal recovery. Mechanical & Structural Requirements 17. Total flashpole system weight shall be less than the current 14 lb design, with the isolated flashpole weight desired below 7 lb. 18. The system shall withstand a 3 ft drop onto steel plate and concrete surfaces without functional damage. 19. The system shall withstand transportation and deployment vibration/shock loads, including truck transport, cargo-container shipment, and open-ocean raft operation (while mounted at the top of a 16 ft pole on an 8 ft wide raft in open-ocean conditions), including random vibration from 5–500 Hz at 1.04 Grms and dynamic multi-axis loading of at least 3 g without structural, electrical, or functional degradation -- 3 of 5 -- UUR Lawrence Livermore National Laboratory June 1, 2026 UUR Page 4 20. The system shall maintain structural integrity and full functionality when stored and transported horizontally and when installed and operated vertically on deployed assets. Field Operations & Maintainability 21. The flashpole shall include a diagnostic test mode capable of low-level illumination of…
