This advanced LED technology is carefully designed and selected to consist of the highest quality LED chipsets for superior performance and reliability. The miniature, high output LED modules can be used with 12 volt Lx Cable Systems powered by magnetic low-voltage or zero-load electronic low-voltage transformers. High Output LED Modules are dimmable on magnetic and electronic low voltage systems. For magnetic systems, a magnetic low voltage (MLV) dimmer should be used. For electronic systems, an electronic low voltage (ELV) dimmer is recommended.
