Recessed lighting transforms spaces - eliminating bulky fixtures while providing clean, even illumination. Whether you're updating outdated can lights or adding recessed lighting for the first time, this guide covers what St. Louis homeowners need to know in 2026.
Why Recessed Lighting?
Design Benefits
Clean aesthetics: - No visible fixture hanging from ceiling - Works with any decor style - Makes ceilings feel higher - Uncluttered appearance
Versatile lighting: - General ambient illumination - Task lighting for work areas - Accent lighting for artwork/features - Adjustable options for different needs
Practical Advantages
Space efficiency: - Ideal for low ceilings (7-8 foot) - No head clearance concerns - Works in tight spaces
Energy efficiency: - LED retrofits use 75% less energy than incandescent - Long lifespan (25,000+ hours) - Lower cooling costs (less heat output)
Recessed Lighting Options
New Construction vs. Retrofit
New construction housings: - Installed before drywall - Maximum options and flexibility - Lower installed cost - Requires accessible ceiling cavity
Retrofit (remodel) housings: - Install through finished ceiling - No attic access required - Higher per-unit cost - Some limitations on sizes/styles
LED Retrofit Kits
The popular upgrade: Replace old incandescent recessed lights with LED retrofit kits.
How they work: - Remove old trim and bulb - Screw LED module into existing socket - Clip new trim into housing - Instant upgrade - no rewiring
Benefits: - Cost: $15-$50 per light - DIY-friendly (if existing lights work) - Multiple color temperatures available - Dimmable options
Integrated LED Fixtures
The modern standard: All-in-one LED fixtures with built-in light source.
Advantages: - Thinner profile (ideal for shallow ceilings) - Air-sealed (better energy efficiency) - Uniform light distribution - Longer warranty coverage
Considerations: - When LEDs fail, replace entire fixture - Less flexibility for future changes - Higher initial cost
Planning Your Layout
General Room Lighting
Spacing guidelines: - Ceiling height ÷ 2 = spacing between lights - Example: 8-foot ceiling = 4 feet between lights - Lights 2-3 feet from walls for even coverage
Quantity calculation: - Measure room square footage - Divide by 25-30 for general lighting - Example: 200 sq ft room = 7-8 lights
Task Lighting
Kitchen: - Over counters (18-24 inches from wall) - Over sink (centered) - Over island (centered, evenly spaced) - Consider adjustable/gimbal trim for work areas
Bathroom: - Over vanity (supplement with side lights) - Over tub/shower (wet-rated required) - General room lighting
Home office: - Positioned to avoid screen glare - Task lighting for desk area - Even ambient throughout
Accent Lighting
Art/feature lighting: - Adjustable (gimbal) trim - Positioned to highlight feature - 30-degree angle from wall typical - Use narrow beam spread
Architectural details: - Wall washing for texture - Grazing for dimensional surfaces - Cove integration for indirect light
Technical Specifications
Light Output (Lumens)
Recommended levels by room:
| Room | Lumens per Sq Ft |
|---|---|
| Kitchen | 40-50 |
| Bathroom | 40-50 |
| Living room | 20-30 |
| Bedroom | 20-30 |
| Office | 40-50 |
| Hallway | 10-20 |
Color Temperature
Measured in Kelvin (K): - 2700K: Warm (incandescent-like) - 3000K: Warm white (popular residential) - 3500K: Neutral - 4000K: Cool white (task/commercial) - 5000K+: Daylight (garage/utility)
Recommendations: - Living spaces: 2700-3000K - Kitchens: 3000-3500K - Bathrooms: 3000K - Home office: 3500-4000K - Garage: 4000-5000K
Trim Types
Baffle trim: Ribbed interior, reduces glare Reflector trim: Smooth, maximizes light output Gimbal/adjustable: Aims light at angles Wall wash: Directs light at wall surface Decorative: Designer appearances
Housing Types
IC-rated (Insulation Contact): - Can touch insulation safely - Required when insulation present - Slightly lower light output - Most common residential type
Non-IC: - Must maintain clearance from insulation - Higher light output - Used in uninsulated spaces
Airtight (AT): - Prevents air leakage - Required by some codes - Better energy efficiency - Often combined with IC rating
Electrical Requirements
Circuit Capacity
Load calculation: - LED recessed lights: 10-15W each - 10 LED lights = 100-150W total - Well within single 15-amp circuit capacity
Circuit sharing: - Can share circuit with other lights - Avoid sharing with large appliances - Consider separate circuit for extensive installations
Dimmer Compatibility
Critical consideration: Not all dimmers work with all LED lights.
Requirements: - LED-compatible dimmer switch - Match dimmer wattage rating - Use recommended LED/dimmer combinations - Test before final installation
Common issues with wrong dimmer: - Flickering - Buzzing - Limited dimming range - Premature LED failure
Switch Location Planning
Options: - Single switch for all lights - Multiple switches for zones - Dimmer for level control - Smart switches for automation
Installation Considerations
Ceiling Requirements
Standard installation: - Adequate ceiling cavity depth - No obstructions (ducts, joists, wiring) - Access for wiring (attic or cut holes)
Shallow ceiling solutions: - Low-profile LED fixtures (2-3" depth) - Surface-mount alternatives - Suspended ceiling options
Insulated Ceilings
In insulated areas: - IC-rated housings required - AT (airtight) recommended - No gaps in insulation vapor barrier - Follow manufacturer clearances
Wet/Damp Locations
Bathroom considerations: - Wet rating above shower/tub - Damp rating elsewhere in bathroom - Verify fixture ratings before purchase
Cost Breakdown
