A bedroom needs light for reading, orientation and a calmer evening routine. Reduce light exposure before bed and minimise it during sleep. Effects depend on spectrum, light at the eye, timing and duration; CCT alone does not guarantee sleep quality.

Layers: ambient (cove or indirect ceiling), task (bedside reading), accent (art spot, under-cabinet linear), wardrobe and night (low floor-level orientation).

Downlights above the bed are one of the most common mistakes — they glare into the eyes of someone lying down and throw harsh shadows. If unavoidable, shift them above the foot of the bed and use a deep-recessed dark-light optic.

Reading light should be individual per occupant — adjustable arm or pendant by the bedside, aimed at the book not the partner. CCT 2700–3000 K, dimmable, CRI ≥ 90.

For evening use, reduce light reaching the eye and limit glare. Warm Dim can create a pleasant atmosphere but does not remove the blue component. CIE recommends lower exposure in the three hours before bed; ordinary lux without spectral information is not a universal biological threshold.

Place night orientation light low and direct it away from the eyes. Use only the intensity and duration needed for safe movement, for example with a sensor. Settings depend on the room and user.

Practical applications

Master bedroom

Ambient cove, individual bedside reading sconces, art spot, wardrobe linear, floor-level night strip on PIR.

Hotel room (Hospitality)

Welcome at the door, Sleep at the bedside, automatic Night after 23:00 (floor orientation to bathroom). One button per scene.

Children's room

Central light for play and a separate reading lamp. Reduce exposure before bed; use night orientation light only when needed.

Guest room

Simple controls: one switch, one dimmer; reading lamps both sides; dim ceiling for orientation.

Advantages

An evening routine with lower light exposure; individual sleep outcomes are not guaranteed
Warm Dim builds the evening ritual without changing fittings
Individual reading lights respect both partners
Night-time orientation lighting designed to minimise disturbance to a partner

Limitations

Cove and indirect lighting need carpentry
Tunable White raises cost
Night sensors need careful sensitivity tuning

Recommendations

Never a downlight directly above the bed — wallwasher, cove or indirect only
Individual reading light each side, dimmable
CCT 2700 K, ideally Warm Dim, CRI ≥ 90
Floor-level night orientation with intensity and duration matched to need
Dimmable ambient with a stable minimum verified for the actual combination
Smart home: one button for Sleep, one for Read

Common mistakes

Downlight overhead — glare and shadows
Bright light at the eye in the evening without regard to spectrum and duration
No dimming at all — full power even at night
Shared dimmer for both sides of the bed
No floor-level orientation — partner woken on the way to the bathroom

In summary

Bedrooms need ambient + task + orientation, never a downlight above the bed. Warm Dim, individual reading lights and a low floor strip are the minimum for premium residential and hotel work.
