An LED (light-emitting diode) high-power wide-angle A-19 lamp needs only a single LED emitter having multiple LEDs. The LED A-19 lamp includes a lamp envelop structure configured for transmission of light therethrough and a base structure coupled to a lower portion of the lamp envelop structure for coupling to an external power source. The dimensions of the lamp envelop structure and the base structure conform to requirement of a conventional A-19 lamp. The LED emitter includes a plurality of light-emitting diodes (LEDs) disposed in a single recess in a substrate and a single lens disposed over the LEDs and the substrate. In a specific embodiment, the emitter is configured to consume electrical power of 30 Watts or higher and to provide light distribution at 130 degrees or wider at 50% peak intensity without additional secondary optical components.
