GE Reveal bulbs fill your rooms with clean, beautiful light. GE Reveal technology filters out dull, yellow rays, bringing out colors and patterns that go unnoticed under regular incandescent light. These bulbs' funnel shape and reflective coating help direct light where it is needed better than a standard incandescent bulb. Use GE Reveal indoor floodlights in indoor recessed track and recessed fixtures to create broad beams of light and make colors and patterns pop. GE Reveal color-enhanced full-spectrum bulbs create enhanced, vivid surroundings in rooms and spaces throughout your home.
