Quick Answer
Clearlight builds the lowest-EMF infrared saunas on the market with a genuine lifetime warranty and excellent build quality. The Premier IS-2 (~$4,400–$5,000) is the best value in the lineup for most buyers. Main drawbacks: 6–14 week lead times, patchy post-purchase support, and prices that are hard to justify when competitors now offer comparable heater tech at 40–60% of the cost.

Clearlight has been the default recommendation in premium infrared sauna circles for years — and for straightforward reasons. Their True Wave II heaters set the EMF standard that every competitor is now measured against, their lifetime warranty is the most comprehensive in the category, and the build quality on their cedar cabins is genuinely excellent.
They're also expensive, slow to ship, and inconsistent with post-sale support. This review covers every model in the lineup, verifies the specs, and gives you an honest read on where Clearlight earns its reputation and where it falls short.

What Makes Clearlight Different
True Wave II Heaters: The EMF Benchmark
Clearlight's True Wave II heaters are a carbon-ceramic hybrid — carbon panels for broad coverage and consistent far-infrared output, with ceramic particulates infused to increase peak heat intensity. The design produces less than 0.3 mG of EMF at typical body distance, verified by independent third-party testing. That figure is the lowest published number in the premium segment — Sunlighten's Signature models measure below 3 mG, their mPulse line higher.
A notable design difference: Clearlight heaters are exposed rather than fabric-covered, minimising how much infrared energy is absorbed before reaching the cabin interior. Some competitors — Sunlighten's mPulse uses Celliant-covered heaters — use cloth covers which independent analysis suggests absorbs a portion of the output.
ELF Shielding — The Feature Nobody Talks About
Clearlight is among the very few sauna brands to actively address ELF (electric low frequency) fields in addition to EMF. ELF is a distinct type of electromagnetic field generated by electrical wiring and components. Most brands focus solely on EMF because it's what customers ask about. Clearlight's ELF shielding is a genuine technical differentiator — and for buyers who are purchasing an infrared sauna specifically because of health concerns, it's the most relevant specification most don't know to ask for.
Lifetime Warranty — What It Actually Covers
Clearlight's lifetime warranty covers heaters and the wood structure for residential use with no time limit. This is stronger than Sunlighten's heater lifetime warranty because it extends to the cabinet itself. The practical value is significant for a $5,000–$10,000+ purchase — a sauna you expect to own for 15–20 years benefits meaningfully from lifetime versus 7-year coverage.
Caveats: the warranty requires product registration and service records. Gaps in maintenance documentation can void coverage for specific claims. Control panel electronics and LED systems on Sanctuary models are not covered for life — read the fine print.
Floor Heaters — A Practical Differentiator
Clearlight Sanctuary models include infrared heaters beneath the floor. This is a meaningful heat distribution advantage — foot and lower-leg warming is where many competitors fall short. Standing heat flows from below as well as the panels, which makes the cabin feel more enveloping and reduces the cold-feet problem that affects cheaper saunas.
Model-by-Model Breakdown
Premier IS-1 — ~$3,400–$4,200
Best for: Solo buyers who want genuine Clearlight quality at the lowest entry price.
The IS-1 is a compact 36"×36"×75" 1-person cabin with True Wave II far-infrared heating and all the core Clearlight credentials — <1 mG EMF, ELF shielding, lifetime warranty, western red cedar or basswood construction. It runs on a standard 120V circuit, which means no electrician and no dedicated circuit — you plug it into a regular outlet.
That 120V capability is the IS-1's most practical selling point for renters or buyers who don't want to budget for electrical work. Heat-up to usable temperature takes 20–25 minutes in a room-temperature space.
The IS-1 is tight for a larger frame — at 36" wide, it's designed for one person sitting upright, not stretching out. If you want to lie down during sessions, look at the IS-2 or Sanctuary models.
Premier IS-2 — ~$4,400–$5,000
Best for: Most buyers. The best balance of space, value, and Clearlight's core technology.
The IS-2 is the model I'd buy. At ~$4,400–$5,000 for a 2-person far-infrared cabin with lifetime warranty and the lowest-EMF heater system in the category, it's the value anchor of the entire Clearlight lineup. Like the IS-1, the standard IS-2 runs on a 120V/15A circuit — no electrician needed for most homes. That makes it one of the most practical premium saunas to install.
Two people can use the IS-2 simultaneously, and a single person has enough room to stretch out on the bench. Cedar construction feels and smells premium from day one. The door seal is tight, and the joinery on Clearlight cabins is consistently described by owners as visibly better than budget brands.
Heat-up time: 20–30 minutes to 125–140°F depending on ambient room temperature.
Premier IS-3, IS-4, IS-5 — ~$5,000–$6,500+
Best for: Households of 3–5 who want to use the sauna simultaneously.
The IS-3 through IS-5 scale the Premier formula to larger groups. At 3-person capacity (~$5,000–$5,800), the IS-3 offers a meaningful footprint upgrade without the jump to Sanctuary pricing. The IS-4 and IS-5 are the right choice for a family of four or five who want everyone to sauna together — but at ~$6,500+ for the IS-4, you're approaching Sanctuary 2 territory, at which point the full-spectrum upgrade becomes worth evaluating.
All Premier models carry the same warranty, EMF specs, and heater technology as the IS-1 and IS-2. The main variables are footprint and electrical draw.
Sanctuary Series — ~$6,000–$14,000+
Best for: Buyers who want full-spectrum infrared (near/mid/far) and have a larger budget.
The Sanctuary line adds a near-infrared LED panel system to the True Wave II far-infrared base. This delivers coverage across the full infrared spectrum simultaneously — near-infrared (targeting surface tissue, collagen, circulation) alongside mid and far-infrared (deep muscle, cardiovascular, detox).
Whether the near-infrared addition meaningfully improves outcomes beyond far-infrared alone is debated. The peer-reviewed literature on photobiomodulation (near-IR's mechanism) is solid, but most sauna-specific research uses far-infrared protocols. The Sanctuary makes sense if you want the full-spectrum option for skin health or recovery protocols — research suggests near-infrared has meaningful effects on collagen production and wound healing — but don't buy it solely expecting superior cardiovascular benefits.
The Sanctuary Y is worth calling out: it's an open-format cabin designed for yoga, stretching, and floor-based positions rather than bench sitting. If your sauna protocol involves lying flat, deep stretching, or floor work, the Y format is more practical than forcing the position into a standard bench-seat cabin.
Post-purchase complaints about the Sanctuary line specifically cite LED system failures within 2–3 years in some units. The lifetime warranty covers this in principle, but warranty claim processing has drawn criticism for slow turnaround.
Outdoor Models — ~$5,000–$8,500
Best for: Buyers planning outdoor installation — patio, garden, dedicated outdoor wellness area.
Clearlight's outdoor line uses weather-treated western red cedar rated for exterior installation. These are infrared cabins rather than traditional wood-burning saunas, so no chimney or fire management is required. The far-infrared heating works identically to the indoor Premier models.
Outdoor installation introduces additional considerations: reinforced flooring or a concrete pad is typically needed for the weight (350–600+ lbs assembled), weatherproofing for the electrical connections, and a covered area or additional weather protection is recommended even for weather-rated cabins in high-precipitation climates.
Lead times for outdoor models are comparable to the indoor range — plan for 6–14 weeks minimum.
Clearlight vs. Sunlighten: The Honest Verdict
Since every Clearlight buyer eventually asks this question, here it is plainly:
Choose Clearlight if:
- EMF is your primary concern — <0.3 mG vs. Sunlighten's 3–12 mG on the mPulse
- The lifetime warranty on both heaters and cabinet matters to you
- You want far-infrared at a lower price than Sunlighten's equivalent cabin
- ELF shielding is important to you (Clearlight is the only brand that offers it)
Choose Sunlighten if:
- You want PulseIQ — independently controlled near/mid/far infrared with six programmable wellness protocols
- Clinical research backing on the heater technology specifically matters
- You want integrated red and near-infrared light in a single system with sophisticated app control
For most buyers who aren't specifically chasing the Sunlighten PulseIQ experience, Clearlight is the stronger long-term value — the lifetime warranty on a cabin you'll use for 15+ years is worth more than it sounds on paper.
What to Know Before Buying
No website pricing. Clearlight requires you to call or submit a quote request. This is a deliberate sales strategy — pricing conversations allow upsells to financing, accessories, and installation. Get the full delivered price including any accessories before comparing.
Lead times are genuinely long. Six to fourteen weeks is the norm, not the exception. If you need a sauna within a month, Clearlight is the wrong brand — look at brands with faster fulfilment.
Assembly is a real project. Most owners manage with a helper over 4–8 hours following Clearlight's instructions, but some buyers report the documentation being ambiguous about electrical integration. DIY assembly on a Sanctuary model can extend significantly. Budget $300–$800 for professional installation if you'd rather not deal with it.
Post-purchase support varies. Pre-sale responsiveness is excellent — Clearlight's sales team is attentive. Post-purchase technical support has drawn criticism for slow response times on warranty claims and technical issues. If something goes wrong 3 years in, be prepared for a longer resolution process than the warranty language implies.
Electrical requirements. The IS-1 and IS-2 standard models run on 120V/15A — a regular household outlet, no electrician needed. IS-3 and larger models typically require a 240V dedicated circuit; add $200–$600 for an electrician if your space doesn't have one. Always confirm the electrical spec for your specific model and configuration with Clearlight before ordering.
FAQ
Is Clearlight sauna worth the price?
For buyers who prioritise lifetime warranty and the lowest-EMF infrared sauna in the premium segment, Clearlight justifies the premium. If you want comparable far-infrared heat at lower cost, Dynamic Saunas and Maxxus offer 80–90% of the Clearlight experience at 40–60% of the price. Clearlight earns its premium through warranty depth and EMF credentials — not unique technology, since the heater design is now widely replicated.
What is the cheapest Clearlight sauna?
The Premier IS-1 (1-person) starts around $3,400–$4,200 and is the most accessible entry point. For a 2-person model, the Premier IS-2 runs approximately $4,400–$5,000. Clearlight does not publish prices — request a quote directly.
How long does a Clearlight sauna take to heat up?
Clearlight saunas reach 125–145°F in 20–30 minutes in a room-temperature space. This is faster than Sunlighten's mPulse line, where real-world heat-up times of 45–90 minutes are commonly reported. In a cold unheated garage, budget 35–45 minutes for Clearlight.
What is the difference between Clearlight Premier and Sanctuary?
The Premier delivers far-infrared only via True Wave II heaters — effective for cardiovascular benefits, relaxation, detox, and recovery. The Sanctuary adds near-infrared LED panels for full-spectrum coverage, targeting additional applications (collagen production, surface tissue recovery). The Sanctuary costs roughly $1,500–$2,500 more per equivalent size. Whether near-infrared adds meaningful sauna benefits beyond far-infrared is still being established in the research literature.
How does Clearlight compare to Sunlighten?
Clearlight wins on EMF (<0.3 mG vs. Sunlighten's 3–12 mG), ELF shielding, lifetime warranty on heaters and cabinet, and price (typically 20–40% less for comparable capacity). Sunlighten wins on programming sophistication (PulseIQ), clinical research backing, and integrated red light delivery. Most buyers focused on safety specs and long-term value choose Clearlight; buyers who want advanced wellness programming choose Sunlighten mPulse.
What are the most common Clearlight sauna problems?
The most reported issues: 6–14 week delivery delays (sometimes longer), slow post-purchase technical support, DIY assembly complexity that runs longer than documented, control panel and LED failures within 2–3 years in some units, and warranty claim processing that can take weeks. The lifetime warranty covers these in principle — getting it honoured quickly is where the friction occurs.
Does Clearlight have an ELF shield?
Yes. Clearlight is among the very few sauna brands to actively shield ELF (electric low frequency) fields in addition to EMF. ELF is generated by electrical wiring and components and is distinct from the EMF that most brands address. For buyers purchasing a sauna specifically for health reasons, ELF shielding is the most meaningful differentiator most don't know to ask about.
Neil's Verdict
Clearlight's Premier IS-2 is the sauna I'd recommend to most buyers in the $4,500–$5,000 range. True Wave II heaters, lifetime warranty, <0.3 mG EMF, ELF shielding, solid cedar construction — it's the most complete package at that price point from any established brand.
The Sanctuary line is worth the upgrade only if you have a specific reason to want near-infrared alongside far-infrared — a skin health protocol, a recovery setup that specifically targets photobiomodulation, or a Sanctuary Y for yoga use. For general sauna benefits, the Premier delivers everything the research supports at a lower price.
What Clearlight needs to fix: the post-purchase support experience and the lead time reality don't match the premium price. Paying $5,000–$10,000 for a sauna should come with faster, more reliable support after the sale. That's the brand's weakest point, and it's worth knowing before you commit.
If EMF is your primary concern and the lifetime warranty matters to you, Clearlight is still the right choice. If you can live with higher EMF and want more sophisticated wellness programming, Sunlighten's mPulse is the alternative. Either way, both brands are building genuinely good saunas — the decision comes down to what you're optimising for.
