Recessed lighting has five main disadvantages: high installation cost, significant heat loss through ceiling penetrations, difficult bulb access, poor light distribution in large rooms, and structural limitations that make installation impossible in some ceilings.
Each recessed can requires cutting a hole in the ceiling and, in most cases, attic access for proper insulation sealing — work that adds labor cost and reduces a home's thermal envelope. Recessed fixtures also concentrate light in a narrow cone directly below the fixture, which means a room larger than roughly 100 square feet typically needs multiple cans to avoid dark corners. That's a fundamental difference from a flush mount ceiling fixture, which spreads light across a wider area from a single installation point.
- Recessed lighting installation typically costs $100–$200 per can including labor, versus $20–$60 for a flush mount fixture swap.
- Each uninsulated recessed can penetration can lose as much heat as a 2-inch hole left open in the ceiling.
- Standard recessed cans produce a beam spread of 30–60 degrees, requiring one fixture per 20–25 sq ft for even coverage.
- Flush mount LED ceiling fixtures like the Hlite 12-inch model deliver 2,600 lumens covering up to 130 sq ft from a single ceiling opening.
- Recessed fixtures in insulated ceilings require IC-rated (insulation contact) housings, which cost more and restrict airflow around the bulb.
