The UNILED II TUNABLE WHITE combines unconventional articulated arm technology with homogeneous, glare-free and low-shadow illumination in various white light colors - based on the course of daylight. The white light change is not achieved by parallel-connected LEDs in different colors, but by high-quality LED chips with TRI-R technology. These emit a very natural light, the color temperature of which can be continuously selected between warm white, neutral white and daylight white. The result is an unsurpassed light quality and a light whose color spectrum is comparable to that of sunlight. This in turn leads to a very high color rendering and color quality, which makes the articulated arm lamp interesting not only for industrial, laboratory and jewelry workplaces, but also for testing gemstones, varnishes or other surfaces.
