Common questions
Sunlighten or Clearlight — which is better?
Sunlighten mPulse wins on wavelength rigour (separate near/mid/far emitters). Clearlight Sanctuary 2 wins on its Jacuzzi-backed lifetime warranty, at a higher price. Comparable on cabin build; Sunlighten publishes more EMF data.
Does the 3-wavelength control matter?
For most users, marginally. Sunlighten lets you run near-only, mid-only, far-only or combined per session — useful for users specifically tuning wavelength exposure. For typical sauna use, Clearlight’s combined full-spectrum delivers the same downstream benefits.
Is Clearlight lifetime warranty better than Sunlighten 7-year?
On paper yes — but in practice premium IR sauna heaters in either brand rarely fail before 10–15 years. The lifetime warranty is reassurance that the Jacuzzi parent company is unlikely to disappear.
Which has better cedar?
Both ship premium cabin wood — Sunlighten cedar, Clearlight basswood or mahogany (your choice). Sunlighten cedar has a stronger aroma; Clearlight basswood is low-odour and often chosen by people sensitive to cedar.
