Narrative:

While taxiing for takeoff for runway 15 at night after being on duty for over 12 hours I departed from runway 15 at the intersection of taxiway 'C' and 15 instead of the end of runway 15. This was approximately 800-1000 feet from the departure end. The aircraft; fortunately; had no problems with the decreased runway available for takeoff. Factors which contributed to this error are fatigue; due to the long duty period I was experiencing. Secondly; cockpit distraction from passenger conversations which caused my concentration to not be as focused on taxiing the aircraft. Thirdly; there were numerous taxiway edge lights out of service at the time which contributed to the loss of position awareness.the tower did not indicate or say anything after departure and rest of flight was uneventful.corrective actions would include limiting the duty period for flight crews to help alleviate any fatigue which may arise from the extended duty period. Secondly; stay focused on taxi operations and not let passenger conversations distract from 'flying the airplane'. Lastly; have timely repairs made to any airport lighting which could have helped illuminate the taxi ways and position awareness.
