Circadian Lighting Control

Ketra: Revolutionary tunable white LED technology that mimics natural daylight throughout the day. Changes color temperature (warm to cool) based on time of day to support your circadian rhythm. Premium solution for clients who want the absolute best in lighting quality, wellness benefits, and color accuracy. Higher investment.

Lutron: Industry-leading dimming and control systems with unmatched reliability. Works with your existing fixtures and bulbs. Options from entry-level (Caséta) to high-end (RadioRA 3, HomeWorks). Best for clients prioritizing control, reliability, and value. Wide price range.

Combined: Many clients use both—Ketra for key living spaces where they spend the most time, Lutron for the rest of the home. This delivers the wellness benefits where they matter most while controlling costs.

Absolutely! Modern wireless lighting systems make retrofits easier than ever:

No Rewiring Required:

• • Lutron Caséta/RadioRA: Wireless communication between dimmers and keypads
• • Smart dimmers: Replace existing switches—no neutral wire needed (most models)
• • Battery keypads: Install anywhere without running wires
• • Ketra retrofit: Replace bulbs/fixtures, control wirelessly

What You'll Need: Compatible LED bulbs or fixtures (we help you select), smart dimmers/switches, and optional keypads or integration with home automation. Installation typically takes 1-2 days for an average home.

We assess your current wiring during consultation and recommend the best retrofit approach for your home.

Not necessarily! Options depend on your goals and budget:

Keep Existing Fixtures:

• • Replace switches with Lutron smart dimmers
• • Use dimmable LED bulbs in existing fixtures
• • Add keypads for scene control
• • Result: Full control without changing fixtures

Upgrade Select Fixtures:

• • Install Ketra in main living areas (kitchen, great room, master)
• • Keep existing fixtures in secondary spaces
• • Best of both worlds—premium where it matters

Full Upgrade:

• • New Ketra or high-performance LED fixtures throughout
• • Best for new construction or major renovations
• • Ultimate in performance and aesthetics

We assess your current fixtures and recommend the most cost-effective approach to achieve your goals.

Yes! Smart lighting delivers measurable energy savings:

Energy Savings Strategies:

• Occupancy Sensing: Lights turn off when rooms are unoccupied (15-30% savings)
• Daylight Harvesting: Dims electric lights when natural light is sufficient (20-40% savings)
• Dimming: Running LEDs at 50% brightness uses ~40% less energy (not linear)
• Scheduling: Automatic shutoff at night or when away
• LED Conversion: LEDs use 75% less energy than incandescent, last 25x longer

Typical Savings: 30-60% reduction in lighting energy costs. For a home spending $150/month on lighting, that's $50-90/month saved, or $600-1,080 annually.

Additional Benefits: Reduced HVAC costs (less heat from lights), longer fixture life, reduced maintenance, utility rebates (available in some areas).
