Few　researches　have　focused　on　the　comprehensive　efficiency　of　tunnel　lighting,　which　plays　a　role　in　improving　the　tunnel　lighting　efficiency.　This　article　defined　visual　recognition　time　as　the　representation　of　visual　performance.　Three　indices,　visual　performance,　light　efficiency,　and　production　cost,　were　proposed　to　study　the　visual　performance　of　test　drivers,　when　drivers　recognized　an　obstacle　in　LED　lighting　environment　with　different　characteristics.　A　total　of　15　light　combinations　were　designed　in　the　middle　section　of　tunnel,　composed　by　5　color　temperatures　and　4　color　rendering　indices　under　8　different　kinds　of　light　brightness.　A　total　of　12　test　drivers　were　selected　to　conduct　the　static　recognition　experiment　in　different　lighting　environments.　Recognition　time,　lighting　performance,　and　production　cost　were　normalized,　and　K-means　clustering　was　applied　to　analyze　these　indices　to　obtain　the　values　of　comprehensive　efficiency　of　LED　with　different　characteristics.　The　results　indicated　that　increasing　the　light　color　rendering　can　improve　the　visibility　without　increasing　the　light　power.　The　following　combinations　of　color　temperature　with　color　rendering,　6500　K　with　70,　5700　K　with　70,　5700　K　with　80,　3000　K　with　80,　3000　K　with　70,　and　4000　K　with　70,　performed　better　comprehensive　efficiency,　showing　better　visual　performance,　higher　light　efficiency,　and　lower　production　cost.
