1. A system, comprising:
a pressurized chamber having a reel installed therein;
a flexible tubular liner configured to be wound around the reel, the liner being extendable into an elongate configuration;
a light source attached to a power line and comprising a plurality of light emitting diodes, the light source and the power line configured to extend within the liner when the liner is in the elongate configuration;
a propulsion unit configured to move the light source within the liner at a desired rate of travel; and
a controller in communication with the light source and the propulsion unit, the controller configured to monitor a temperature of an area adjacent the light emitting diodes, to shut down power to the light emitting diodes and stop movement of the light source if the temperature reaches a first temperature threshold, and to thereafter resume power to the light emitting diodes at a decreased power output and resume movement of the light source at a decreased rate of travel.
