As well as white, the K2 is available in green, cyan, blue, royal blue, red, red-orange and amber versions. Dominant wavelengths for these devices at a junction temperature of 25°C are 530 nm, 505 nm, 470 nm, 455 nm, 627 nm, 617 nm and 590 nm respectively.

The PWT1 has a very small form factor enabling manufacturers to build flashlights with smaller optics and less weight than ever before. The product has no lens and emits uniform white light thanks to a blue-emitting indium-gallium-nitride chip coated with a yellow phosphor.
