A hand-held light emitter for employment in combination with a gel applied to teeth for a whitening enhancement during employment by a user. The device features a housing surrounding an interior cavity holding LEDs or other light projecting components which provide illumination to the users mouth through an aperture communicating with the lights in the interior cavity. A pair of handles extend to a position below the aperture to allow for a proper positioning of the aperture to align with an engagement to the users mouth. The distance of central portions of the handles providing support for the housing and aperture from an underling support may be varied by rotation of the handles or telescopic engagement.
