1. A multi-mode apparatus for providing spherical illumination and communication after introduction in a denied-access environment, said apparatus comprising:

  • an environmentally impervious containment means having the capacity to pass light spherically, and comprising a sphere of a transparent solid plastic material prepared from catalytically cured polyester styrene clear casting compound;

    a light producing means disposed within said containment means to provide a source of light for spherical passage from said apparatus, said light producing means comprising a plurality of light emitting diodes substantially equally spaced from each other circumferentially about and equidistant from the center of said sphere, at the radial extremities of two orthogonally intersecting planes;

    a magnetically operated means for switching from one operating mode of said apparatus to another including the "ON" and "OFF" conditions of said apparatus, said switching means being disposed in said containment means close to the external environment so that an external magnet may be brought in operative juxtaposition with said switching means;

    a means for providing autonomous power to said activating and mode changing means and said light producing means, said power providing means being disposed within said containment means;

    programmable means disposed within said containment means for operating on said light producing means to produce continuous, strobe and coded light output from said light producing means, said programmable means also connected to said power producing means and said activating and mode changing means; and

    an LED mode indicator and a mode circuit disposed in said containment means, said circuit connected to said switching means and said LED mode indicator.
