A lighting apparatus is provided including an array of light emitting
diodes (LEDs) disposed on a base. The base is configured to move heat
away from the array of LEDs to other portions of the base and further to
the atmosphere or an adjacent housing. In one embodiment, a native oxide
on the base electrically insulates the base from the LEDs. In another
embodiment, a cover is removably disposed over the array of LEDs, and
removal of the cover prevents electrical energization of the LEDs.
