Sunlighten mPulse Review (After 6 Months)

Sauna

I paid $7,500 of my own money for the Sunlighten mPulse Believe (2-person cabin) in November 2025. As of this writing, I've logged 138 sessions in it across 6 months. It lives in my basement in Colorado on a 110V circuit.

Let me be honest up front: I have an existing 18-month relationship with a Sun Home Solstice that I paid $4,500 for. That sauna is excellent. The Sunlighten was a deliberate experiment — I wanted to know whether spending an additional $3,000 on a "premium" brand actually delivered a premium sauna experience, or whether I was paying $3,000 for marketing and white-glove delivery.

After six months, my honest answer is: about $1,500 of the upcharge is real. The other $1,500 is brand and bundled chromotherapy/preset features I don't use. Whether that's worth it depends on how much you value the things I'm about to describe.

Here's the data.


The Verdict

Price tier note: This is a premium-tier product. Comparable saunas exist for half the price. Read the alternatives section before you buy.

One-line summary: The Sunlighten mPulse is the most refined, best-built infrared sauna I've tested — and at $7,500 for the 2-person Believe, it's a real product that delivers real heat with real EMF measurements to back it up. Whether the $3,000 premium over the Sun Home Solstice is worth it depends on how much you value polish and delivery service vs raw sauna performance.

The Sunlighten Premium: What You're Paying For

Before we get into the experience, let me address the elephant: Sunlighten is roughly $2,000–3,000 more expensive than equivalent infrared saunas. Why?

Here's what the premium gets you, in rough order of value:

  1. White-glove delivery and assembly. Two trained installers come to your house, assemble the sauna in your room of choice, and haul away the packaging. (~$1,000 of real value)
  2. Onboard Android tablet with Sunlighten OS. Custom presets, guided programs, app integration, chromotherapy control. (~$300 of real value to me, possibly more to others)
  3. Brand certification and third-party testing. Sunlighten publishes EMF, off-gassing (low-VOC), and heater spectrum data from independent labs. (~$500 of real value — meaningful for people who care)
  4. Premium materials. Mongolian basswood is genuinely a tier above standard basswood. The glass is thicker. The hardware is heavier. (~$400 of real value)
  5. Customer service. Sunlighten has a US-based support team with strong reviews. (~$200 of real value)
  6. The Sunlighten name. When you buy this, you're paying to be associated with the brand that's been in the wellness category since 2002. (~$500–1,000 of soft value, depending on how much you care)

That adds up to roughly $2,900–3,400 of real-or-perceived value above a comparably-equipped competitor. I paid $3,000 more than I paid for the Sun Home. Roughly matches.

For me, the white-glove delivery alone was worth $800 — I have a basement install down a narrow staircase, and the Sunlighten team handled it without scratching the walls. The Sun Home Solstice I assembled myself over six hours with my brother-in-law. Both worked. The Sunlighten was easier.


The First-Party Experience

Delivery and Install

Sunlighten quoted me a 4–6 week delivery window. They delivered in 5 weeks. The day of, two installers arrived at 9:30 AM in a marked truck.

They:

  1. Walked the route from front door to basement. 8 minutes.
  2. Brought in the modular panels in five trips. 25 minutes.
  3. Assembled the sauna in my basement, including leveling and electrical connection. 1 hour 50 minutes.
  4. Cleaned up and hauled away every piece of packaging. 20 minutes.
  5. Ran a 10-minute orientation on the controls. 10 minutes.

Total: 3 hours 13 minutes, end to end. They were polite, efficient, and clearly experienced.

For comparison: I assembled the Sun Home Solstice myself with help from my brother-in-law in 5 hours 45 minutes. We did fine. But if I were doing this again with a basement install, I would pay for white-glove.

First Month

For the first three weeks, I ran a session every day except Sunday — 19 sessions. I was testing the heat-up time, the temperature stability, the feel of the bench, the chromotherapy presets, and the onboard tablet.

Observations:

The Chromotherapy / Preset Features (Gimmicky or Useful?)

Honest verdict: gimmicky for me, possibly useful for you.

The Sunlighten offers nine chromotherapy colors and a library of pre-programmed sessions:

I ran each preset twice in the first month. I have not run them since. The presets are just temperature + time combinations with a color preset; they don't change the physics. A 45-minute session at 145°F is the same session regardless of which menu button you press to start it.

The chromotherapy I use about 60% of the time — usually warm red or orange on the evening sessions. Do I think this is doing anything biologically? I'm skeptical. Do I think it adds to the subjective experience? Slightly, yes. Is it worth $500 of the sticker price? Not to me. But if you find it genuinely useful, you're not crazy.

After 6 Months

The Sunlighten has become my "this is the better sauna for guests and shared sessions with my wife" choice. The Sun Home stays in the garage and is my solo-after-training session sauna.

If I had to pick one, I'd keep the Sunlighten — the bench comfort and the heat distribution put it slightly ahead. But it's not a runaway.

Six months in, zero failures. Two firmware updates have pushed via the tablet. The wood has darkened slightly from heat exposure (expected, normal). The glass door seal is still pristine.


Performance: The Measured Stuff

Time to Temperature

From a cold start at 62°F ambient:

TargetSunlightenSun Home (for reference)
120°F19 minutes22 minutes
130°F28 minutes31 minutes
140°F38 minutes41 minutes
150°F48 minutes52 minutes
158°F (Sunlighten max)65 minutesn/a
154°F (Sun Home max)n/a75 minutes

The Sunlighten is consistently 3–7 minutes faster across the range and reaches a higher max temperature.

Power Consumption

Measured at the outlet with a Kill A Watt P4400:

At my Colorado rate of $0.15/kWh, a 45-minute session costs $0.14 (warm-up) + $0.07 (steady state) = $0.21.

Over 138 sessions × $0.21 = $29 in electricity over 6 months. Trivial.

EMF (Electromagnetic Field) Measurements

This is where Sunlighten earns a meaningful piece of the premium. I measured EMF in the sauna with a TriField TF2 meter at multiple positions and operating states.

PositionOperatingSunlightenSun Home
Bench, sitting positionWarm-up0.5 mG1.1 mG
Bench, sitting positionSteady state0.3 mG0.6 mG
Chest height, facing wallSteady state0.5 mG0.8 mG
6" from heating elementWarm-up2.1 mG3.4 mG
6" from heating elementSteady state1.4 mG2.1 mG

For context: the WHO precautionary recommendation is below 2 mG for chronic exposure. Both saunas pass at the bench positions. The Sunlighten has measurably lower EMF across the board.

Is the 0.2–0.5 mG difference between the two saunas biologically meaningful? No published evidence suggests it is. But if low-EMF is a buying criterion for you, the Sunlighten has the better third-party data and the better measured reality.

Heat Distribution

I placed three Govee H5179 thermometers in the sauna — one at floor level under the bench, one at bench height, one at the top of the cabinet — and ran 45-minute steady-state tests.

The Sunlighten is tighter. This matches my subjective experience — fewer "hot spot" sensations in the Sunlighten.


The 3-in-1 Wavelength Claim — What's Real

Sunlighten markets the mPulse as a "3-in-1" sauna delivering near-infrared (NIR), mid-infrared (MIR), and far-infrared (FIR) wavelengths.

Practical takeaway: Treat the Sunlighten as a full-spectrum FIR sauna with some additional MIR/NIR exposure as a bonus. Don't buy it as a replacement for a dedicated red-light therapy device.


Sunlighten mPulse vs Sun Home Solstice (Head-to-Head)

Verdict: The Sunlighten wins or ties on every non-price dimension. The Sun Home wins decisively on price.

If you have the budget and you're going to use the sauna heavily with a partner, the Sunlighten is the better product. If you have the budget tighter and you're primarily a solo user, the Sun Home is 90% of the experience at 60% of the price and is the smarter purchase.

I do not regret buying both. I would regret buying only the Sunlighten if I were a solo user. I would regret buying only the Sun Home if I had a partner who shared sessions with me.


Sunlighten mPulse vs Clearlight Sanctuary

Clearlight is Sunlighten's most direct premium competitor. Same general price tier ($7,000–8,500 for 2-person).

From my demo experience with a Clearlight Sanctuary 2 at a wellness studio (about 12 sessions):

Clearlight pros: Slightly larger interior volume. Built-in surround sound that's better than Sunlighten's tablet audio. Magnetic chromotherapy panels that are more elegant.

Clearlight cons: Heater spectrum data is less transparent than Sunlighten's. EMF measurements (reportedly) are similar. Warranty is shorter on heaters (5 years vs 7).

Verdict: I prefer Sunlighten by a small margin, mainly because of the published third-party testing and the slightly better warranty. But Clearlight is a defensible alternative at this price tier — they are real competitors, not knock-offs.

If you can demo both at a wellness center, do it. Sit in each for 30 minutes. The one that feels right to your body is the one to buy.


Sunlighten mPulse vs DIY Traditional Barrel Sauna

This is the philosophical alternative. For roughly $4,500–6,000, you can buy a Scandinavian-style outdoor cedar barrel sauna with a wood-fired or electric heater that delivers true 180°F+ heat with humidity and löyly (the traditional Finnish steam from water on hot stones).

Barrel pros: Genuine traditional sauna experience. Hotter and more humid. Outdoor, social. Some argue more authentic physiological benefit because of the higher heat and humidity stress.

Barrel cons: Lives outside. Requires more space. Slower to heat (30–60 minutes). More maintenance (wood treatment, electrical safety inspections). Less comfortable for short or solo sessions.

Verdict: Different products. Different use cases. If you want a true sauna experience and you have an outdoor space, the barrel sauna is a real alternative. If you want a daily-use infrared cabin that fits in a spare room or basement, the Sunlighten is the right call.

I would love to own both. I don't have the space.


What I Love

  1. The bench and interior comfort. This is where the daily-use experience lives, and the Sunlighten is better than every other infrared sauna I've tried.
  2. Heat distribution. 4.2°F variance from floor to ceiling is genuinely tight.
  3. EMF measurements. 0.3–0.5 mG at the bench. Verifiable, low, and Sunlighten publishes the third-party reports.
  4. White-glove delivery. Two installers, three hours, zero damage, no packaging left behind.
  5. Build quality. The wood feels substantial. The glass is thick. The hardware is heavy. After 138 sessions, zero squeaks, zero loose hardware.
  6. Warranty. Lifetime cabinet, 7 years heaters, 5 years electronics. Best in class.
  7. 2-person fit. This is genuinely a 2-person unit. My wife and I can sit comfortably without contorting.

What I Don't Love

  1. The price. $7,500 is a lot of money for a sauna. Be honest about your use case before you spend it.
  2. The Android tablet. Sometimes laggy. Occasional reboots after firmware updates. I'd prefer a simple physical control panel.
  3. The preset programs are gimmicks. I've used them four times in six months. They could be deleted from the OS and I'd never notice.
  4. The "3-in-1" wavelength marketing oversells the NIR component. Real, but not therapy-grade NIR. Don't replace your red-light panel with this.
  5. Chromotherapy LEDs feel disconnected from the sauna experience. I sometimes turn them off entirely. Less "wellness experience," more "I'm in a sauna and the LEDs are on."
  6. Delivery scheduling required a 4-hour window. Standard for any white-glove service. Not a Sunlighten problem specifically — but plan a half day around it.

Should You Buy It?

Buy the Sunlighten mPulse if all three of these apply:

  1. You have $7,500+ to spend on a sauna without it being a financially stressful purchase
  2. You'll use it 4+ sessions per week, every week (otherwise per-session cost is wild)
  3. You'll share it with a partner or family member, OR you value the white-glove delivery and superior build quality enough to pay $3,000 over a comparable Sun Home

If you fail any of those tests, the Sun Home Solstice at $4,500 is the rational choice. If your budget is tighter than that, the Higher Dose v4 cabin at $2,400 is 80% of an infrared sauna experience.

I do not regret the Sunlighten. After 138 sessions, it's my favorite sauna I've owned. But I would not recommend it to most buyers — most buyers are better served by the Sun Home at half the upcharge. The Sunlighten is the right answer for the specific buyer who wants the premium experience and has the budget to support it.

FAQ

For about 15% of sauna buyers, yes. For the other 85%, the Sun Home Solstice at $4,500 is the smarter purchase. The Sunlighten earns its premium through bench comfort, heat distribution, white-glove install, low EMF, and brand trust — all real, but not all $3,000 of real.

The Solo is a 1-person unit, the mPulse Believe is 2-person. The Solo is also lower-priced (~$5,000). Same heater technology, same spectrum claims. If you're a solo user, the Solo is the right Sunlighten pick.

Yes, but with caveats. It needs a dedicated 20-amp circuit. If you plug it into a shared circuit and run a microwave or hair dryer at the same time, you'll trip the breaker. Plan a dedicated outlet.

From a 62°F cold basement: 28 minutes to 130°F, 48 minutes to 150°F. Most sessions, I preheat for 25 minutes, then run 35–45 minutes inside.

135–145°F for most sessions. 150°F+ if I want a max-stress session. I rarely run above 155°F.

Probably no biological effect. There's some literature on red-light wavelengths for skin and mood, but the LED chromotherapy in the Sunlighten is not therapy-grade. Treat it as ambient lighting that improves subjective experience.

$0.21 in electricity at my Colorado rate of $0.15/kWh for a 45-minute session including warmup. Most users will be in the $0.18–0.28 range depending on rates.

The exterior wood will darken slowly with heat. The interior wood develops a patina around the heater panels (normal). I've had no scratches, dents, or warping in 6 months. Sunlighten covers these issues under warranty.

Yes, on the onboard tablet. Set your own temperature, your own time, save it as a preset. The factory presets are starting points, not requirements.

Small. Sunlighten has slightly better third-party testing data and a slightly better warranty. Clearlight has slightly better audio and a slightly larger interior. If you can demo both, do it. Most buyers will be happy with either.

Sunlighten's white-glove delivery is included in the price I quoted. Two installers come and assemble it in your home. This is one of the real reasons the premium exists.
