4-inch LM4X-DM-400 lamps and power supplies

NASA Shared Services Center is seeking to procure four 4-inch LM4X-DM-400 LED lamps and two power supplies for pressure sensitive paint measurements at the Transonic Dynamics Tunnel. The procurement is designated as a brand name requirement for specialized instrumentation equipment with highly technical specifications, including optical power output greater than 20W at 400 nm wavelength, TTL logic-controlled operation, light pulse generation capabilities from 10 microseconds to 10 seconds, and operation under varying atmospheric pressure conditions down to 5 psia. The solicitation documents indicate this is a sole-source procurement justified for Innovative Scientific Solutions, Inc. (ISSI), which is identified as the only company capable of developing these specific lamps with the necessary optical, operational, and environmental characteristics. The government will award the contract to the lowest-price technically acceptable offer that meets all requirements. Critical dates include a deadline for technical and contractual questions by July 24, 2025 at 7:00 AM CT, and quote submissions due by July 28, 2025 at 9:00 AM CT.

This procurement is set aside for small businesses under NAICS code 334516 (Analytical Laboratory Instrument Manufacturing). Innovative Scientific Solutions, Inc. (ISSI) appears to be the incumbent or preferred contractor, described as a world leader in developing pressure sensing instrument equipment specifically for NASA Langley and NASA Ames wind tunnel applications. While the total contract value is redacted in the documentation, the procurement involves a relatively small quantity of highly specialized equipment with delivery expected within 6-10 weeks after order receipt. The equipment will be delivered FOB Destination to NASA's research facilities, specifically for use in the Transonic Dynamics Tunnel for advanced pressure measurement applications. Vendors must be registered in the System for Award Management (SAM) and provide two points of contact with their quotations to the designated contracting officer, Shanna Patterson.
