1. A rechargeable handheld lighting device, comprising:
a cylindrical body forming an inner wall and an outer wall, and further having a distal end and a proximate end;
at least one peltier tile disposed along the outer wall and towards the proximate end of the cylindrical body, each of the at least one peltier tile having a first side for coming into contact with a user's hand and a second side which forms part of the inner wall of the cylindrical body;
at least one lighting element disposed at least partially within and towards the distal end of the cylindrical body;
a conversion component electrically connected to the at least one lighting element and the at least one peltier tile; and
at least one rechargeable gel pack disposed within the cylindrical body and directly contacting the second side of the at least one peltier tile, wherein the at least one rechargeable gel pack enlarges the temperature differential between the first and second surfaces of each of the at least one peltier tile during handheld initiation; and
an insulating aluminum foil lining disposed along the entire inner wall of the cylindrical body to insulate and reduce warming of the at least one rechargeable gel pack during operation.
