The Radionic ZX series were introduced by Radionic Hi-Tech in 2008. After years of development, this task light is top notch quality BUT AFFORDABLE PRICED. It is better than the well-known brand names yet less costly !! The light output of the ZX series is well distributed by the carefully spaced LEDs with a 120° angle, allowing perfect light distribution. Since our ZX series fixtures have between 56 and 80 LEDs, light is distributed evenly across the entire fixture, eliminating those bright spots normally seen in fixtures with fewer LEDs. Our engineering team did not forget about convenience. Included with each fixture is a quick connect power cord, easy to install mounting clips, a linking cord that allows multiple fixtures to be connected together, and a direct or butt connector that allows two fixtures to be mounted side by side with no space between them. The ZX series were the first undercabinet fixtures in the world to adopt the Lighting Facts label. Another key element of the ZX fixtures is the low operating temperature. The fixtures operate on average only 11°C above ambient temperature measured on the surface of the fixture, and about 12.2°C above ambient temperature measured at the LEDs. The ZX series is so reliable, that since 2008, the internal driver or LED field failure rate has been under 0.1% (or the equivalent of 1 of every 1000 fixtures - while the industry averages about 3.5% or 35 out of 1000).
