Sunlighten mPulse review: are the Conquer and the Believe worth the premium?
A tablet runs the mPulse and doses red light and near-, mid- and far-infrared separately. We checked PulseIQ against the studies and match each cabin to a buyer.
By Adam Bognar, Editor
The Sunlighten mPulse is worth its quote if you'll use PulseIQ, which drives red light and each infrared band separately from an Android tablet in the wall. The two-person Believe fits a couple. We compared the Believe with the three-person Conquer and read Sunlighten's claims against the research. The line answers a fair criticism, which holds that most full-spectrum saunas blend near-, mid- and far-infrared into one undifferentiated glow and call it versatility. Its preset programs carry names like Detox and Heart Health. Sunlighten sells it by quote and posts no price.
An Android tablet runs the mPulse cabin
Sunlighten builds the mPulse in basswood or eucalyptus around its patented SoloCarbon heater panels. CELLIANT fabric heater covers line the interior walls, and the chromotherapy lighting sits recessed. A built-in Android touchscreen runs the show, and you can start a session from it or from the phone app over Wi-Fi. Either one will preheat the room or schedule a session for later, and yes, the tablet streams.
The model names mark sizes. The Believe seats two and the Conquer seats three, with the same technology inside. The tablet puts an operating system where a conventional infrared sauna has a thermostat, and Sunlighten's pitch rests on that software. Decide how much it matters to you before you judge the price.

PulseIQ sets the mPulse line apart by controlling red light and near-, mid- and far-infrared independently. The bands reach different depths, and PulseIQ sets each one's intensity and its point in the session. Sunlighten argues that each wavelength does its best work at a specific dose, which a blended cabin can't deliver. The argument holds as far as it goes, and no mainstream competitor does it.
The size of the benefit is where Sunlighten's case gets thin. Most of the clinical infrared research, the Waon work among it, gave patients far-infrared heat under clinical supervision, and those results don't carry over cleanly to a cabin at home. PulseIQ gives you the widest and most controllable spectral toolkit on the market. The peer-reviewed research doesn't show that the toolkit doubles the benefit, so we'd buy it for the capability and wouldn't count on a multiplier.
The programs help most by making sessions easy to repeat
The presets are where the tablet earns its keep. Detox, Weight Loss, Heart Health, Relaxation, Muscle Recovery and Anti-Aging each sequence heat and wavelengths toward a goal, with a Customize slot beside them, so you choose a goal and leave the temperature to the program. Sunlighten says it built the programs from 37 clinical studies. For its Heart Health protocol it cites a 2005 university study, run on its own heaters, that found a 6.5 mmHg drop in systolic blood pressure.
We treat that result the way we'd treat any science a manufacturer funds. It points the same way as the independent literature, where regular sauna use is associated with cardiovascular benefit, but that literature covers frequent heat over months and says nothing about any specific preset. The programs' main value is behavioral. They make a session effortless to start and pleasant to repeat, and repetition is the only variable the research is unambiguous about.

Sunlighten mPulse Believe
“Full-spectrum is done properly here, and it pays off if you'll use every band.”
Headcount decides between the Conquer and the Believe
Both cabins share the same technology, so we'd choose on footprint and on the circuit your room can take. Sunlighten posts no mPulse prices. On Oct 6, 2026, the affiliate store Outliyr listed the two-person Believe at $8,699 and the three-person Conquer at $10,099, against regular prices of $9,399 and $12,199.
Our sizing advice is the same as for any sauna. Buy for the number of people who'll sit in it every week, and leave the housewarming guests out of the count. A couple who saunas together fits the Believe. The Conquer earns the extra money if a third seat will get used, or if you'd like room to stretch out on your own.
Whatever you're quoted, ask what promotion is live. On Oct 6, 2026, Sunlighten's site advertised up to $2,300 off saunas, and its posted prices for the Amplify II and the Signature II sat 13 to 14% under regular. Our mPulse pricing guide covers all five sizes and the circuit each one needs.

Sunlighten claims low EMF, and the circuit can cost extra
The cabin's build matches its price. Sunlighten offers it in basswood or in eucalyptus it says is sustainably sourced, and adds thick insulation and a finish that reads as furniture more than kit.
Sunlighten's EMF story is strong too. Its manufacturing process cuts electromagnetic fields to levels the company describes as virtually undetectable, which matters if you're buying on the EMF figure. In infrared marketing it often is, so give our decoder on the subject ten minutes before you read any brand's claims.
Each cabin plugs into its own dedicated circuit. Sunlighten's Sep 2026 spec sheets put the Believe on 120V/20A with a NEMA 5-20 outlet and the Conquer on 240V/20A with a NEMA 6-20 outlet. If the room has no such outlet, an electrician adds one, and that bill falls outside Sunlighten's quote. Running cost barely registers. By our calculation, a 45-minute session at full draw costs at most about 31 cents in the Believe and 46 cents in the Conquer at 17 cents a kWh.
Who should buy the mPulse?
Buy the mPulse if you want the most controllable infrared sauna made and the quote fits without wincing. It's a luxury done properly. Sunlighten owns the smart full-spectrum idea, and this is its best version, with separate dosing for each wavelength and presets you can start from your phone. Before you sign, make sure you'll use the part you're paying for.
Skip it if what you want is the health habit. The evidence-backed core of infrared sauna is repeated far-infrared heat, and Sunlighten's own single-band Signature II delivers that, and its store listed the eucalyptus Black Edition at $5,499 on Oct 6, 2026. Weighing infrared against a traditional hot room at this budget is a different decision with its own tradeoffs, and our infrared-versus-traditional hub walks through it.

Common questions
- Is the Sunlighten mPulse worth the money?
- The Sunlighten mPulse is worth the money if you'll use its wavelength control and programs. Nothing else doses red light and each infrared band separately, and the build quality matches the price. If you mainly want the core sauna habit, the evidence supports repeated far-infrared heat, and Sunlighten's own Signature II or any good far-infrared cabin delivers that for thousands less.
- How much does the mPulse Conquer cost?
- Sunlighten sells the three-person mPulse Conquer by quote and posts no price. On Oct 6, 2026, the affiliate store Outliyr listed it at $10,099 against a regular $12,199 and the two-person Believe at $8,699. Sunlighten's site advertised up to $2,300 off saunas that day, so ask what offer is live before you accept a number.
- What's the difference between the mPulse Conquer and Believe?
- The mPulse Believe seats two and plugs into a dedicated 120V/20A circuit, and the Conquer seats three and needs 240V/20A. Both run the same PulseIQ wavelength control on SoloCarbon heaters, with the same tablet and programs. We'd buy for the number of people who'll sauna weekly, and a three-person cabin also makes a roomier solo sauna.
- Does the mPulse need special electrical work?
- Yes. The two-person mPulse Believe plugs into a dedicated 120V/20A circuit, and the three-person Conquer needs a dedicated 240V/20A one. If your room lacks the outlet, an electrician adds it, and that bill falls outside Sunlighten's quote. By our calculation, a 45-minute session costs less than 50 cents in electricity at 17 cents a kWh.
