Superflux is the trademarked name for a series of medium power through-hole mounted LEDs of a particular shape manufactured by Lumileds. They consist of a square package, with the internal diode mounted to four leads (two cathode leads, two anode leads) for better heat conduction and an integrated dome lens. This package is now often called a Piranha package, since the Superflux name is trademarked. The most common use of these LEDs are light panels, emergency lighting and automotive LED tail-light lighting (though they have recently been superseded by SnapLEDs in many automotive applications). These wide angle LEDs provide large areas of light and a wide viewing angle in a small compact diode. Additionally, due to the larger amount of metal in the LED, they are able to handle higher currents (up to 70mA), which is not possible in 5mm LEDs. The higher current allows for the much higher light output required for tail-lights and emergency lighting
