A light engine comprises a pair of LED active elements mounted on a common header having first and second terminals. The first terminal is connected to the cathode of the first LED active element and the anode of the second LED active element, while the second terminal is connected to the anode of the first LED active element and the cathode of the second LED active element, thereby connecting the LEDs in an anti-parallel arrangement. A light engine having a single insulating or semi-insulating substrate having formed thereon plural LED active elements with associated p- and n-type contacts forming cathode and anode contacts, respectively, for each LED active element is also provided. The LED active elements may be mounted in a flip-chip configuration on a header having a plurality of leads. The header may include a pair of leads adapted such that two LEDs may be flip-mounted thereon with the anode of the first LED and the cathode of the second LED contacting one lead, while the cathode of the first LED and the anode of the second LED contact the other lead. In addition, the header may be adapted to permit a substrate having multiple active elements to be mounted thereon.
