This Hole-IN-The-Wall fixture
Engineered Lighting Products makes these amazing recessed fixtures.  Very modern, very cool.  This precast ixture is made of GRG (Glass-fiber Reinforced Gypsum) and is 16.25" square to mount to vertical studs in a wall (16" on center). After roughing in the fixture to the framing and adding romex wiring from a wall switch, drywall is added to the edges of the fixture and drywall mud is applied to make the fixture "disappear" into the wall. Once installed, the fixture actually appears to be part of your wall and looks like a custom formed lighting niche.

This fixture has been converted for LED (was 26-Watt CFL previously) and comes with a new MaxLite (very good quality) LED bulb with nice warm color (2700K).

Retail is over $800
