Called XQ-E, the device gets the 1mm die from its XP-E2 LED, and a domed XQ package with a 110° output.

We are going to make white and RGB all available at the same time.”

Peak planned white output is 287 lm at 3W, 85°C.

Thermal resistance is down, to 7°C/W from 9°C/W of the XP-E, said Scheidt.
Applications are expected in portable, indoor directional, architectural and vehicle lighting.
