The ADJ ULTRA LB18 is a sophisticated 5-in-1 color mixing LED linear fixture engineered for professional stage, studio, and event lighting applications where high-quality light and color accuracy are paramount. The "5-in-1" designation refers to its advanced LED light engine, which combines five distinct, dedicated color emitters: Red, Green, Blue, Amber, and White (RGBAW). This configuration provides an exceptionally wide and nuanced color gamut, allowing for the creation of deeply saturated hues, subtle pastels, and a full spectrum of high-fidelity white light with precise color temperature control from warm amber to cool daylight. The dedicated white and amber LEDs are particularly significant, enabling superior color rendering for skin tones and neutral subjects, making this fixture ideal for video production, broadcast, and photography in addition to live events.

Configured in a linear bar format, the fixture produces a smooth, even wash of light ideal for illuminating backdrops, cycloramas, and sets, or for use as an eye-level fill or key light. Its design often incorporates high-quality optics and diffusion to blend the individual LED outputs seamlessly, eliminating color shadows and hot spots. Control is comprehensive, offering full DMX-512 operation for integration with lighting consoles, as well as standalone modes with built-in effects and sound activation for simpler setups. Fixtures in this class may also include wireless control options or digital networking ports for streamlined multi-fixture control.

Built with a robust housing, the ULTRA LB18 is designed for both permanent installation and portable use, featuring multiple mounting points for rigging or placement on stands. Its efficient LED technology delivers high luminous output with relatively low power consumption and minimal heat emission. By merging broadcast-grade color quality with the flexible form factor of a linear fixture, it provides lighting designers and videographers with a versatile and powerful tool for creating both vibrant dynamic looks and perfectly balanced, color-accurate illumination.
