Building on the market-leading innovations of hot testing and Freedom from Binning™, Philips Lumileds introduces LUXEON® T, the next generation illumination-grade LED tested and specified at 85°C to ensure in-application performance with tight color control, to within 3-Step MacAdams (SDCM).
Optimized for efficacy and supported by the industry-leading forward voltage of 2.7V and the lowest thermal resistance of 3 Kelvin per watt, LUXEON T allows designers to achieve the highest possible system efficacy and the flexibility to reduce the number of emitters, all without compromising on high color rendering (CRI) across the full Correlated Color Temperature (CCT) range from 2700K to 5000K.
“With its high efficacy and luminance, LUXEON T is ideal for directional applications such as MR16 and PAR retrofit lamps,” says Kathleen Hartnett, Product Line Director. “LUXEON T is able to deliver high center beam candle power (CBCP) and precise optical control, which are required to deliver the narrow beams desired for these systems.”
LUXEON T delivers up to 140 lumens per watt at 350 mA, 85°C in neutral white at 5000K 80 CRI minimum from a compact 3.7mm x 3.7mm package. The breakthrough performance of LUXEON T is realized through Philips Lumileds technology leadership—in epitaxial growth delivering leading wall plug efficiency and hot cold factor, new phosphors to enhance conversion efficiency, and package optimization for light extraction and lowest thermal resistance.
LUXEON T is now available in five different CCTs, 2700K, 3000K, 3500K, 4000K and 5000K all specified at high-CRI, 80 minimum. In addition to the market-leading 80 CRI range, LUXEON T is available with 95 typical CRI and exceptional red rendering (R9) of 90, making it ideal for the professional lighting market. To enable system level performance improvements in outdoor and industrial applications including high bay, street and roadway lighting, LUXEON T will be extended to the 70 CRI range in January 2013.
