The lamp gives forth a powerful beam of light in a 20 foot wide by 60 foot long cone. This light is equivalent to a brightly lit room, and, depending on which lens is selected, has the following additional effects:
- Yellow - this lens cuts through illusions and phantasms, revealing them for what they are.
- Pale blue - this lens cuts through fog, rain, smoke or other mundane obstacles to vision.
- Orange - this lens works as a sort of x-ray vision, revealing spaces beyond walls, doors or other barriers. It penetrates up to two feet of stone or wood, or six inches of metal.
- Deep purple - this lens reveals extra-planar or phase-shifted objects within its area of effect.
