What Makes the Sunlighten Amplify Different

The Sunlighten Amplify series isn’t your typical infrared sauna. While most infrared models max out around 140-150°F, the Amplify targets serious performance users who want traditional sauna heat combined with infrared benefits.

Sunlighten calls this their “performance sauna,” and after three months of testing, I understand why. The hybrid heating technology creates an experience that sits between traditional steam saunas and standard infrared units.

The Technology Behind the Heat

The Amplify uses two distinct heater types working together:

👉 SoloCarbon Far Infrared Heaters: Sunlighten’s patented coating technology delivers 99% infrared efficiency. These panels provide the deep-penetrating infrared waves that target your core body temperature.

👉 High-Intensity Halogen Heaters: Two 500-watt full-spectrum heaters add immediate, intense heat to the cabin. These create the scorching temperatures that make the Amplify unique.

This dual-system approach means you get both infrared benefits and traditional sauna heat levels – something no other infrared sauna achieves.

Setup & Installation

The Amplify series uses Sunlighten’s Magne-Seal assembly system, making setup surprisingly straightforward for such a substantial sauna.

Electrical Requirements

The biggest advantage of the Amplify over premium models like the mPulse is power requirements. While most high-end saunas need 240V electrical work, the Amplify runs on standard household voltage.

Key Requirements:

• Dedicated 120V 20A circuit
• NEMA 5-20 outlet
• Professional electrical installation is recommended

Most homes don’t have 20-amp outlets, so budget $200-400 for electrical work. This is still far less than the $800-1,200 needed for 240V installation.

Assembly Process

My assembly took 105 minutes with one assistant. The magnetic panel system makes connections secure without visible hardware.

Assembly Steps:

1. Floor panel placement (heaviest component)
2. Wall panel magnetic connections
3. Roof panel installation (requires two people)
4. Electrical connections verification
5. Door installation and alignment

The magnetic system allows wood expansion without compromising the seal – a clever engineering solution.

Space Planning

Clearance Requirements:

• 4 inches between the sauna and walls
• 12 inches above the sauna for ventilation
• 8 inches behind the unit for electronics cooling

The Amplify II footprint (50.9″ x 45.9″) fits most spaces, but measure carefully. The door swing adds another 28 inches to the width requirements.

Testing Methodology

I tested the Amplify II through 65 sessions over 90 days, tracking temperature performance, energy consumption, and health impacts using calibrated instruments.

Performance Results

Heating Performance

The Sunlighten Amplify consistently impressed with heating speed and maximum temperatures.

Heat-Up Times (Tested Average):

• 100°F: 15 minutes
• 120°F: 28 minutes
• 140°F: 42 minutes
• 150°F: 48 minutes
• 165°F: 58 minutes (maximum tested)

These times assume a 70°F starting temperature. Colder environments add 10-15 minutes.

Temperature Distribution

Using multiple thermometers, I mapped heat distribution across the cabin:

Zone Temperatures (at 150°F setting):

• Head level: 148°F
• Chest level: 152°F
• Bench surface: 147°F
• Foot level: 145°F

The 7°F variance represents excellent heat distribution for an infrared sauna. Most models show 15-20°F differences.

Energy Consumption

Power Draw Results:

• Heating phase: 1,880 watts
• Maintenance phase: 1,200-1,400 watts
• Average one-hour session cost: $0.30 (at $0.17/kWh)

The full-spectrum heaters automatically shut off when temperatures exceed 165°F, preventing overheating while maintaining efficient operation.

EMF Measurements

EMF levels measured at normal seating distance:

Magnetic Field Results:

• SoloCarbon panels: 0.2-0.4 mG
• Full-spectrum heaters: 0.8-1.2 mG
• Overall cabin average: 0.6 mG
• Bluetooth speakers (when active): 2.1-2.8 mG

Electric Field Results:

• General cabin area: 15-25 V/m
• Near full-spectrum heaters: 45-65 V/m
• Bluetooth speaker vicinity: 85-120 V/m

These levels are well below the 10 mG industry standard for “ultra-low” EMF and significantly lower than common household devices like hair dryers (60-200 mG).

The slightly elevated readings near full-spectrum heaters and Bluetooth speakers are consistent with their higher power output but remain within generally accepted safe ranges.

Daily Use and Performance

Morning vs Evening Sessions

The Amplify performs differently depending on session timing, creating distinct experiences for various goals.

Morning Sessions (6-8 AM): The sauna becomes an energizing ritual. Starting at 155°F, I reach deep sweating within 10 minutes. The intense heat jumpstarts circulation and metabolism, creating alertness that lasts hours. The quick heat-up means I can complete a full session in 35 minutes total.

Evening Sessions (6-8 PM): Perfect for recovery and sleep preparation. The high heat creates deeper relaxation than gentle infrared. After stepping out, the natural cooling triggers drowsiness within 90 minutes. This timing produces the best sleep quality improvements.

Real-World Performance Differences

Compared to Standard Infrared Saunas, the Sunlighten Amplify feels like an entirely different category. Where most infrared saunas warm gradually, the Amplify hits you with immediate intensity. Sweat begins in 8-10 minutes versus 15-20 minutes in standard models. The heat sensation resembles traditional saunas while maintaining infrared benefits.

Seasonal Performance Variations: Winter usage requires 10-15 extra minutes for full heat-up when located in unheated spaces. Summer performance actually improves – the sauna reaches target temperatures faster when ambient temperature exceeds 75°F.

Load Testing Results: Single-person use allows maximum temperatures. Two-person sessions reduce peak temperature by 8-10°F due to body heat absorption and air circulation changes. Three people (Amplify III) create noticeable hot spots near full-spectrum heaters.

User Experience Evolution

Week 1-2: Adjustment Period
Initial sessions felt overwhelming at high temperatures. Started at 140°F for 15-minute sessions. The intensity surprised me – much different from spa infrared experiences.

Week 3-8: Optimization Phase
Discovered optimal temperatures for different goals. Recovery sessions work best at 155°F. Cardiovascular training benefits peak at 160°F. I found that 25-30-minute sessions provide maximum benefits without exhaustion.

Week 9-12: Performance Integration
The sauna became essential to my routine. Post-workout sessions eliminated next-day soreness. Evening sessions improved sleep consistency. The high heat tolerance transferred to hot weather performance.

Practical Performance Notes

Heat Distribution Reality: The halogen heaters create focused heat zones. Sitting directly in front generates intense localized warming. Side positions provide more even heat distribution. The SoloCarbon panels deliver consistent background infrared.

Full-Spectrum Heater Behavior: These units automatically shut off when cabin temperature exceeds 165°F. This safety feature initially confused me, but it prevents dangerous overheating. The cycling maintains optimal temperature without user intervention.

Sound System Integration: The Blaupunkt speakers handle high temperatures without distortion. The bluetooth connection remains stable throughout sessions. The audio quality exceeds most sauna sound systems – clear enough for podcasts and audiobooks.

Pros and Cons

What I Loved

• Unmatched Temperature Performance: The 165°F capability puts Amplify in a class by itself among infrared saunas. This isn’t just marketing – you genuinely feel the difference compared to standard 140°F models.

• 120V Power Advantage: Not needing 240V electrical work saves hundreds of dollars and makes installation feasible for most homes without major electrical upgrades.

• Solid Build Quality: The SoloCarbon panels and magnetic assembly system feel premium. Wood quality matches much more expensive models with superior fit and finish.

• Fast Results: Higher temperatures trigger benefits faster. I achieved deep sweating in 8-10 minutes versus 15-20 minutes in standard infrared saunas, maximizing session efficiency.

• Chromotherapy Enhancement: The built-in light therapy adds ambiance and potential mood benefits. The remote control makes color changes convenient during sessions.

• Premium Sound System: The Blaupunkt speakers deliver surprisingly good audio quality. Bluetooth connection is reliable and loud enough to hear over ventilation noise.

• Proven Technology: SoloCarbon heating panels have decades of development behind them. The 99% infrared efficiency claim is backed by clinical testing and real-world performance.

Notable Limitations

• Basic Control System: No smartphone app or programmable sessions. The simple panel works but feels dated compared to smart sauna systems from competitors.

• Heat-Up Wait Time: It takes nearly an hour to reach the maximum temperature, which requires planning. Spontaneous sessions aren’t practical without advance preparation.

• Intense Experience: The high heat isn’t for everyone. Users preferring gentle infrared sessions might find the Amplify overwhelming for regular use.

• Full-Spectrum Heater Heat: The halogen heaters get extremely hot. Accidental contact could cause burns. The safety covers help but requires constant awareness.

• Space Requirements: The Amplify II feels cramped with two larger adults. The marketing suggests a 2-person capacity, but comfort varies significantly by user size.

• No Floor Heating: Unlike some competitors, Amplify models don’t include floor heaters. This isn’t necessarily negative, but it is worth noting for comparison shopping.

• Limited Smart Features: No WiFi connectivity, remote monitoring, or advanced scheduling options that premium models offer.

Deal Breakers vs Minor Issues

These Are NOT Deal Breakers:

• Heat-Up Time: Most users adapt within 2 weeks by starting to preheat during dinner prep or evening routines. It becomes automatic, like preheating an oven.
• Two-Person Fit: Solo sessions provide maximum benefits anyway. Most couples alternate sessions rather than sharing, making size less important than expected.
• Basic Controls: Simple controls mean fewer things to break. The core functions work reliably without app crashes or connectivity issues that plague “smart” saunas.

Real Deal Breakers Would Be:

If you need instant-on convenience (can’t wait 45-60 minutes for heat-up), want gentle 110°F sessions (buy regular infrared), or can’t dedicate time for 45+ minutes daily (not worth the investment).

For serious users seeking performance benefits, these limitations become minor routine adjustments that fade after the first month of ownership:

Do these advantages outweigh the drawbacks for your needs? Despite minor negatives, the Amplify II’s benefits clearly justify the investment. 👇
