PCS Heater Bulbs P/N: 103390-005 QTY 210 P/N: 106587-001 QTY 30

NASA Shared Services Center seeks 210 units of PCS Heater Bulbs P/N 103390-005 and 30 units of P/N 106587-001, with a proposal due date of June 26. This is a sole source procurement from Precision Control Systems, Inc., with organizations able to challenge the sole source determination by 7:00 a.m. Central Standard Time on June 26.

Place of performance is Edwards Air Force Base, California. The bulbs are quartz-tungsten-halogen lamps required for integration and testing of a large-scale heater in a ground test effort at NASA Armstrong Flight Research Center. The 103390-005 bulbs are 100 W/in specification with approximately 20-inch lengths; the 106587-001 bulbs are 400 W/in specification with approximately 5-inch lengths. Sole source justification rests on specialized physical and performance characteristics: the electrical leadwires and passthrough holes in the heater hardware were designed specifically for the exact measured lengths of these PCS bulbs. Competing vendors' similar bulbs exhibit dimensional variations of approximately 0.25 inches in total length and leadwire positioning, preventing proper routing through heater hardware. Lower-efficiency alternatives would cause excessive temperatures on the water-cooled heater's back side, potentially resulting in hardware damage or hazardous zinc-coating fume production.

Delivery must be completed within 14 weeks after contract award. The contractor must provide NASA shipping information two days in advance of delivery. NAICS code is 339999, All Other Miscellaneous Manufacturing; PSC is 6695, Combination and Miscellaneous Instruments. Procurement will utilize FAR Part 12 commercial item procedures. Shanna L.
