The torch slips out easily. The torch tube has mechanisms for it to be unscrewed manually from the top and bottom. The the tip of the torch is a conical plastic lens, which can be removed easily. Beneath that, there is some sort of PCB (?) board with a small bulb on it, with an on/off switch on the side.

The circumference around the PCB has 2 rubber bands that were removed with tweezers. The PCB can be lifted to reveal the battery ports. The bottom part of the torch was twisted off to reveal a conical spring, possibly what allows it to be ejected from the lamp.
