Cree, represented by Cutter Electronics , a market leader in LED solid-state lighting components, has released warm white XLamp LEDs that produce up to 124 lumens at a correlated colour temperature (CCT) of 3,000 K when driven at 700 mA.
Unlike many warm white power LEDs, XLamp LEDs are qualified to run at up to 700 mA. With this, XLamp LED lighting-class brightness and efficiency is now available in warm white from Cree.
The availability of high-performance LEDs across a full range of colour temperatures can allow lighting manufacturers to build cost-effective LED fixtures for many indoor home and office applications, helping meet the need for energy-efficient, environmentally friendly lighting.
The new warm white is available in both the XLamp XR-E and XR-C power LED families that are binned to the proposed ANSI standard, allowing manufacturers to select LEDs the same way they select bulbs today.
According to Cree Lighting, the LED industry has struggled to boost the brightness and efficiency of warm white LEDs, which have historically offered significantly lower performance than cool white LEDs.
The new XLamp warm white LEDs hold a stable colour point and offer lighting designers and architect the first lighting-class warm white LED light source for general illumination applications that have traditionally been lit with incandescent light sources.
