Surprised nobody noticed... Press release below.

Nichia 219 white LED offers typical 140 lumen output at 1 W input power with 5,000 K color temperature. Using a uniformly phosphor coated chip, Nichia 219 has the industry leading source brightness and tightest optical footprint. The spatial color uniformity is also optimized with Nichia's leading phosphor technology. At 350 mA drive current, the typical forward voltage is only 3.0 V. Additionally, this package is capable of drive currents up to 1.5 A.
Nichia intends the 219 white LED to be Energy Star® compliant. This includes ANSI standard chromaticity binning, full color temperature selections, high CRI performance, LM-80 test data, and other relevant certifications. To enhance the delivered lumen output under thermally stabilized conditions, Nichia engineers have drastically improved the lumen maintenance at higher junction temperatures.
To make Nichia 219 user friendly, Nichia has incorporated an electrically isolated heat sink in the LED design, and lowered the junction to board thermal resistance, while minimizing the package size to a mere 3.5 mm x 3.5 mm. The symmetrical package shape with a dome lens makes it perfect for secondary optical and mechanical designs.
