These are designed for streetlights and similar lighting applications, but can be used almost anywhere you need a lot of warm white light.
The array consists of a metal clad PCB measuring 132mm x 73mm with 28 x 1 watt warm white LEDs attached. The LEDs are configured as 4 paralleled strings of 7 LEDs in series. See here for a 28 optic array to suit this PCB.
