Narrative:

Night visual approach to 11L at tus. First officer (first officer) flying. Clear night. Runway acquired on downwind. Advised tower 'runway in sight' on base. During dogleg left turn to final the first officer lost sight of his visual acquisition of the runway and lost his intercept angle to the final approach fix. I also lost sight of the runway as my head was down configuring the aircraft and completing the before landing checklist. Tower advised of a low altitude alert. We advised tower we had lost sight and requested vectors to another approach. Landed without incident. Low runway light setting contributed to our loss of situational awareness.regardless of who is flying; in the future I will not allow the aircraft to descend below the FAF altitude outside of the fix at any time; even on a visual approach. I will also be more forceful in asking the tower to turn up the runway lights on night visuals if the lighting environment is difficult.
