The Altman UV-703 is a compact, high-output ultraviolet (UV) wash light designed to create dramatic fluorescent effects in theatrical, haunted attraction, nightclub, and special event lighting. This fixture utilizes a specialized UV lamp that emits light predominantly in the long-wave ultraviolet A (UVA) spectrum, around 365 nanometers. When this "blacklight" illuminates materials treated with fluorescent paints, dyes, or phosphors, it causes them to glow vividly with bright colors, while leaving non-reactive surfaces relatively dark. The UV-703 is built around a Fresnel lens optical system, which provides a smooth, even wash of UV light with a soft, diffused edge that is ideal for covering large areas like stages, sets, or walkthrough environments.

Constructed for professional use, the fixture features a durable steel housing with a dichroic reflector optimized for UV reflection and a safety glass to contain the lamp. Its compact size allows for easy placement and focusing. The Fresnel lens can be adjusted to "spot" or "flood" the beam, providing control over the coverage area and intensity. The fixture is designed to operate on standard stage lighting power (typically 120V or 240V AC) and connects via a stage pin or Edison plug, depending on the configuration. Due to the nature of UV light, the fixture should be used with appropriate safety considerations, including avoiding direct eye exposure and ensuring the lamp is properly shielded.

The Altman UV-703 is a specialized tool for creating otherworldly and high-impact visual environments. Its ability to make fluorescent elements pop with an eerie, invisible-to-visible light transformation is unmatched by standard color-mixing fixtures. When used in combination with fluorescent set pieces, costumes, and makeup, it becomes a key component in productions ranging from psychedelic concert experiences to spine-chilling haunted houses, adding a layer of visual magic that operates outside the normal visible spectrum.
