Sunlighten vs Clearlight - Which Sauna Should You Choose?

If you’re comparing Sunlighten vs Clearlight, you’re already looking at two of the top infrared sauna brands out there.

And this is usually where things get tricky.

On paper, they check a lot of the same boxes:

• Full spectrum and far infrared options
• Low EMF designs
• Premium materials and builds

So it’s not immediately obvious which one is actually the better fit.

After digging into both brands—and hearing from a lot of buyers along the way—the difference isn’t really about specs.

It comes down to how you want the experience to feel before and after you buy.

Quick Verdict (If You Just Want the Answer)

If you want the short version:

Go with Sunlighten if you want a more guided, all-in-one experience

• Built-in red light (on mPulse)
• More structured buying process
• Feels like a complete system

Go with Clearlight if you want more flexibility and control

• Custom, outdoor, or conversion options
• Choose your setup more directly
• More hands-on overall

Neither is better across the board—it depends on what fits your situation.

The Simplest Way To Decide

If you’re still unsure, it usually comes down to how you plan to use the sauna.

• If this is your first sauna and you want something that feels straightforward from day one, most people are more comfortable with Sunlighten.
• If you already know what you want—or you’re trying to fit a sauna into a specific space (basement, backyard, etc.)—Clearlight tends to make more sense.
• If built-in features like red light therapy are important, Sunlighten has the edge.
• If you’re thinking about custom sizing, outdoor use, or converting an existing room, Clearlight is usually the better fit.

Most buyers end up leaning one way pretty quickly once they look at it in terms of their setup rather than just the specs.

If you already have a sense of which direction you’re leaning, it’s worth taking a closer look at each brand:

→ Sunlighten sauna models and features

→ Clearlight sauna options and configurations

How These Two Brands Actually Differ

Both companies offer similar core features, but the experience of buying and owning the sauna tends to feel different.

Sunlighten is built around a more complete, integrated experience.
From the way the models are presented to how features like red light are built in, everything is designed to work together. It’s generally a smoother process, especially if you’re newer to infrared saunas.

Clearlight leans more toward flexibility. You have more freedom in how the sauna is configured, where it’s installed, and how everything is set up. That’s a big advantage for certain buyers—but it also means you’re making more of the decisions yourself.

What Each Brand Offers

Sunlighten

Sunlighten keeps things fairly straightforward with three main options:

• Signature → Far infrared
  A simpler, more traditional infrared sauna
• Amplify → Full spectrum
  Higher intensity sessions
• mPulse → Full spectrum + built-in red light + advanced controls
  Their most feature-rich model

Most buyers compare these side-by-side and choose based on features and budget.

Clearlight

Clearlight separates things a bit differently:

• Premier → Far infrared
  A straightforward far infrared sauna
• Sanctuary → Full spectrum
  A full spectrum sauna with front and surrounding heat
  

And then expands from there with:

• Custom sauna builds
• Conversion kits
• Outdoor sauna options

This gives you more flexibility, especially if you already have a specific setup in mind.

Full Spectrum vs. Far Infrared

Both brands offer both, so this isn’t really where the decision is made.

Sunlighten tends to position full spectrum as a more advanced option, while Clearlight presents both as equally valid depending on preference.

In practice, both will deliver a similar type of experience—it’s more about how you want to use the sauna than which brand you choose.

Red Light Therapy

This is one of the clearer differences between the two.

Sunlighten integrates red light directly into its mPulse models, so it’s built into the sauna.

Clearlight offers red light as well, but usually as a separate system rather than something built in.

So:

• Sunlighten → more integrated
• Clearlight → more modular

Custom & Outdoor Options

This is where Clearlight stands out more clearly.

Both brands offer custom options, but:

• Sunlighten tends to focus on indoor setups with a more guided process
• Clearlight offers: outdoor sauna models, conversion kits, more flexibility in how the sauna is installed

If you’re planning something outside or working with an existing space, Clearlight usually has more to offer.

EMF & Testing

Both brands position themselves as low EMF, and both provide supporting information.

Sunlighten typically publishes consistent EMF ranges, while Clearlight shares third-party testing showing low levels at seating distance.

Because these measurements are taken differently, they’re not directly comparable.

In real-world use, both are considered low EMF, and this usually isn’t what determines the final decision.

Real Customer Feedback/Ownership Experience

Because we regularly hear from readers researching and purchasing these saunas, we’re able to see patterns that don’t always show up in spec sheets or marketing materials.

Sunlighten

Most of the feedback around Sunlighten centers on the buying experience and support.

People often mention:

• A very helpful, responsive sales team
• Clear guidance when choosing models
• A smoother overall buying process

At the same time, a few things come up consistently:

• Delivery timelines can vary
• Setup may take more effort than expected
• Some mixed experiences after installation

We also see questions around heat expectations, especially from first-time infrared users, but that's too be expected.

Clearlight

Clearlight feedback tends to focus more on the product and setup flexibility.

People often mention:

• Solid build quality
• Strong performance once fully heated
• More options for installation (custom, outdoor, etc.)

On the flip side:

• Less guidance during the buying process
• Communication can be inconsistent at times
• More responsibility on the buyer to manage setup

If you're narrowing things down, it helps to look at both brands side by side:

→ Compare Sunlighten models
→ Compare Clearlight options

Design & Overall Feel

This is more subjective, but still worth noting.

Sunlighten feels:

• More modern
• More polished
• More like a “wellness brand”

Clearlight feels:

• More traditional
• More straightforward
• More focused on function

Most people will have a preference here pretty quickly.

Pricing

Both brands fall into a similar range:

• Entry-level: ~$3K–$5K
• Mid-range: $5K–$8K
• Premium: $8K+

So pricing alone usually isn’t the deciding factor.

Final Verdict

Both are very strong options—but they’re built for slightly different buyers.
