Clearlight Premier IS-1 vs Sunlighten mPulse Aspire
Pick by which axis you weight. The Premier has the better-evidenced EMF posture at the seat and addresses ELF, but it is far-only. The mPulse is the more complete spectrum with real near-infrared, at a higher price and a contested EMF figure. In our view the Premier is the EMF pick and the mPulse is the spectrum pick; both are among the more defensible cabins we score.
The two premium honesty brands, each strong on a different axis. The Clearlight Premier IS-1 ($5,299) is a far-only cabin whose Clearlight-commissioned VitaTech report reads under 1 mG including at the seat, which leads our EMF axis. The Sunlighten mPulse Aspire ($6,500) is full spectrum with real near, mid, and far emitters, but its under-1 mG claim is position-contested, with independent TriField readings up to about 2 mG at the seat.

FAQ
- Which has lower EMF at the seat?
- On the evidence we have, the Clearlight Premier: its commissioned VitaTech report reads under 1 mG including at the seated position, uncontested by any independent reading we found. The Sunlighten mPulse's under-1 mG claim is position-sensitive, with independent TriField testing reading up to about 2 mG at the seat.
- Is the Sunlighten really full spectrum and the Clearlight not?
- The mPulse Aspire delivers near-infrared from real 660 and 850 nm LEDs alongside mid and far, so its full-spectrum label is backed by a separate emitter. The Premier IS-1 is a far-only cabin and does not claim full spectrum, so nothing is overstated there; it competes on EMF, not spectrum.
