I have a project planned for some high-end under cabinet lights, using 2 watt Nichia Jupiter LEDs. The LEDs are packaged and mounted by LuxDRIVE in their IO Moon product. The IO Moon takes the jupiter LED and has it mounted on a very thin printed circuit board. The pcb is two layer, however, only the top layer is electrically active – the planes on the top and bottom are connected by a bunch of through-plated vias and the bottom plane is not masked, instead it is left as an exposed, tinned surface.

Luxdrive claims the moon can operate at a recommended current of 350mA in ‘free air’ at 25°C ambient. However, to achieve the full 500mA drive current, a heatsink is required.

I have chosen 70° viewing angle lens and a warm-white phosphor. The LED looks very nice, however, I’ve only been able to run it at 1/10th power so far. The color is a big improvement over the very blue common white led.

Here’s some pictures!
