SOLE SOURCE LETTER.pdf

This is a sole source letter from Solar Lighting International to the Missouri Department of Transportation, St. Louis District, dated August 7, 2026. The letter confirms that Solar Lighting International is the manufacturer of the X-35, Stealth, and Stealth II series solar street lighting systems and offers special direct pricing for Federal, State, and Local government agencies. The department has determined that only Solar Lighting International can provide the STEALTH II 120-23-O-IXC Solar Lighting Solution to meet its specific operational needs. The contract period runs from the date of award through August 31, 2027, with options to renew for two additional one-year periods.

The Missouri Department of Transportation selected this sole source solution to address high copper wire theft in the St. Louis District. Solar lights operate independently using sunlight, eliminating the need for wires, conduits, junction boxes, and associated contractor labor costs. Because all components are mounted above ground and out of reach, the lighting systems eliminate wire theft risks while maintaining safe roadway illumination. Solar Lighting International is identified as a Buy American compliant U.S. manufacturer and sells through both wholesale distribution channels including CED, Grainger, and Border States Electric, as well as directly to government agencies.
