Wall Offset
A common starting point is to place the first row of lights about half the fixture spacing from the wall.
Lumens
Lumens vary by fixture and trim. Use fixture photometrics for final lighting levels.
Room Use
Kitchens, offices, and work areas usually need more light than bedrooms, hallways, or accent areas.
Final Placement
Adjust for joists, ducts, cabinets, fans, shower zones, insulation rating, dimmers, and fixture manufacturer instructions.
