Abstract: A light canister may be removably mounted either on protruding and typically exterior building corners, or flat walls. A vertical groove accommodates the corner, support brackets and hooks inside the groove to engage the support bracket. The bracket has two corner contact plates connected by a protruding connection forming a space between the wall and itself when the bracket is attached. The hooks are dimensioned to fit snugly within the space and are conveniently V shaped. Spring clips on the canister can engage vertical cylindrical bars fitted to a flat wall, or vice versa. A builtin electrical plug directly engages a wall mounted plug. Triple internal reflectors, two adjustable allow the light to be directed at will.
