20:00 – 22:30
Dusk
Warm amber light at 1800K fills the room. A descending tone sequence, derived from slowed field recordings, signals the body to release melatonin. The room becomes a cocoon.
The night,
recomposed.
HALO shapes the light and sound of your room across every hour of sleep. A precision bedside instrument for those who understand that rest is a discipline, not a setting.
Discover HALOAcross the night
Three phases, one instrument.
22:30 – 06:00
Deep Night
Total darkness. A calibrated pink-noise profile, tuned to the acoustics of your room, masks disturbances without calling attention to itself. The device is present only in its silence.
06:00 – 07:30
Dawn
Light climbs gradually from 2200K to 4000K over ninety minutes. A sparse soundscape—recorded at dawn in the Shimane countryside—rises almost imperceptibly. You wake, rather than being woken.
The Object
Presence in the room.
Machined from a single billet of 6061 aluminium, then finished by hand in Miyota, Japan. The HALO is an instrument first and an object second — but it earns its place on the bedside table. Its weight, its temperature, the way it catches the last light of evening: every detail was considered because every detail shapes the experience of rest.
The ceramic-composite coating is soft to the touch and warm to the eye — a deliberate counterpoint to the cold glass and plastic of the devices it replaces. No screen. No notifications. Just a quiet, luminous presence.
Engineering
Precision is the luxury.
The HALO is built around a custom 64-channel LED array and a balanced-mode acoustic radiator. Every component was specified for one criterion: does it improve the quality of rest? If not, it was removed.
64
LED channels
Independent spectral control from 1500K to 6500K, with CRI ≥ 97 across the full range.
22–48
Hz adaptive noise
BMR driver with real-time room acoustic calibration, updated every 90 seconds through the night.
0.3 s
fade resolution
Light and sound transitions are computed at sub-second intervals. No perceptible steps, only gradient.
A word
Sleep is the last unfragmented hour. We built HALO to protect it — not to track it, not to gamify it, not to sell you a subscription to your own rest.
