LED Engin, Inc., of San Jose, California USA, a announced immediate availability of LuxiTune, a compact, single emitter light engine that delivers directional light with halogen-style dimming. LuxiTune reportedly hugs the black body curve from 3000K down to1800K. Luminous flux is 1100 lumens, equivalent to a 60W halogen lamp. Luminous efficacy is 63 lumens per Watt hot and includes the secondary, TIR optic. The company contends that this is far higher efficacy than that of rival products that utilize multiple emitters and reflectors. At full intensity, color rendering index (CRI) is 90 and LuxiTune maintains a CRI average of 85 and R9 red content of 70 as it dims. LuxiTune has a diameter of 50mm. According to LED Engin, LuxiTune allows lighting designers to quickly and easily create a compact lighting fixture that works with standard 0-10V dimmers or via a DMX interface.

The LuxiTune light engine is comprised of a 12-die. The die are matched to within 3 MacAdam ellipses (SDCM) and dimming tracks the black body curve to within three SDCM, producing what LED Engin describes as consistent, natural light across the full dimming and CCT range. LuxiTune employs a multi-layer ceramic substrate that the company claims minimizes the package thermal resistance and provides an almost stress-free environment for the chips providing effective heat dissipation and maximum light emission. LED Engin says that these features ensure that color point stability is maintained throughout the product’s long service life. Optics are available in 24°, 32° and 45° beam angles. Furthermore, the company says that the lenses facilitate uniformity over angle, maximize lumens in the beam while minimizing glare and produce a gentle roll-off profile at the beam edges.

President and CEO of LED Engin, David Tahmassebi, commented, “Our customers in the hospitality and high-end residential sectors have been eager for an LED-based lighting solution that tunes along the black body as it dims while leveraging our strengths in lumen density and lux-on-target performance. We are excited to release LuxiTune, a professional-grade replacement for halogen downlights where dimming is required. Lighting designers who love the benefits of LED but also desire the warmer, softer tones of dimmed halogen light no longer have to compromise.”
