An LED lamp includes a base, a first LED module attached to a bottom surface of the base, a second LED module attached to a top surface of the base, and a reflector engaged on the top surface of the base. The reflector has an outer surface facing and angled with the second LED module. Light generated by the first LED module radiates to a bottom side of the LED lamp, and light generated by the second LED module is reflected by the outer surface of the reflector to radiate out and toward a lateral side of the LED lamp.
