A Covenant Light Amplifier, also known as a Plasma Torch, is a light amplifying device used by Covenant forces to increase visibility in low light environments and locations which feature dense terrain. They have been encountered by UNSC troops when assaulting Covenant encampments and sometimes ships. These devices are portable enough for Covenant troops to move them from camp to camp, or camp to ship.
They are rod shaped, with the top holding a sphere, which is essentially the bulb. It has a handle and could be activated by a switch near the top on the side of the handle opposite the bulb. It can be found on the first Halo game dotted all around the level Assault on the Control Room. They have been in use since the first Halo game, but have had slight differences in appearance. They operate by emitting a blue plasma glow whenever they detect motion nearby, conserving energy by automatically shutting off once the motion leaves the immediate area.
There are minor differences between the versions, in the original Halo game they emitted an actual plasma flame, while in Halo 3 they extend slightly and then emit a soft blue light.
- Covenant Light Amplifiers bear slight resemblance to the staffs carried by the Pfhor in Bungie's earlier game Marathon.
- Though the Covenant Light Amplifier is utilized by Covenant troops, when any UNSC forces penetrate the staff's radius it will prop itself up and "light" the way for them.
