Human Centric Lighting

Light that works with your body.

Your home adjusts its light across the day to match your body's natural rhythm, brighter and cooler in the morning when you need to be alert, warmer and softer in the evening as you wind down. PIXIE HCL does this automatically, so you never have to think about it.
Morning — bright & energising
Afternoon — clear & focused
Evening — warm & winding down
PIXIE Human Centric Lighting in a home setting
So what does that actually mean for your home?
Human Centric Lighting

The right light. At the right time.

Your body has a clock. Light is the signal it runs on.

Cool, bright light in the morning tells your body it's time to be alert and get moving. Warm, soft light in the evening tells it to slow down and prepare for sleep. This isn't a feature, it's biology. And most homes get it completely backwards.

PIXIE HCL automatically adjusts your home's lighting colour temperature across the day, so your light is always in sync with your body's natural rhythm, without you having to touch a thing.

Backed by circadian science. The connection between light and human physiology is well-established. Light wavelength and intensity directly affect cortisol and melatonin production, the hormones that control your energy and sleep cycles.
A PIXIE homeowner on living with Human Centric Lighting every day.
And here's the system that delivers it.
The HCL System

It takes two. And it's worth it.

PIXIE HCL isn't a single device, it's a system. The dimmer controls the colour temperature. The downlight delivers it. You need both for HCL to work, and your electrician can have it installed in a standard afternoon.

PIXIE RippleShield HCL Dimmer
Step 1 — The Controller
PIXIE RippleShield™ Dimmer
SDD400RSBTAM

The smart dimmer that controls colour temperature and intensity automatically across the day, or on demand via the PIXIE app, voice, or a wall switch. Standard 30 mech wall plate fitment, plugs straight in where your existing dimmer is.

SAL Coolum PLUS RS Colour Tunable Downlight
Step 2 — The Light Source
SAL Coolum PLUS RS
S9068TW35WHRS

The SAL downlight engineered to pair with the PIXIE HCL dimmer. Colour tunable from warm to cool, RippleShield compatible, and available in multiple reflector colours to suit your interior. Standard 92mm cutout.

💡
Important: The PIXIE HCL dimmer and SAL Coolum PLUS RS downlight work together as one system. Either product alone won't deliver the HCL result, your electrician will source and install both.
See how it works
PIXIE HCL: the dimmer, the downlight, and the difference it makes
It does more than
just change colour.
What it does

More than just changing colour.

The PIXIE HCL system is a full member of the PIXIE ecosystem, everything you'd expect from a smart home dimmer, with the added intelligence of circadian lighting built in.

PIXIE PLUS app — HCL colour temperature controls
App control

Adjust colour temperature and brightness from the PIXIE PLUS app, individually or across a whole scene.

Automatic scheduling

Set HCL to adjust across the day automatically. Once it's programmed, you don't need to think about it again.

Voice control

Works with Google Assistant, Amazon Alexa, and Siri Shortcuts. Say the word; the lights respond.

Deep, smooth dimming

Trailing-edge phase dimming to very low levels: no flicker, no buzz, no sudden drop-out at the bottom of the range.

Plug-and-play install

Standard 92mm cutout — your electrician swaps out the existing dimmer. No ceiling patching, no extra wiring, no drama.

On-wall control

A PIXIE wall switch anywhere in the room can also control the HCL dimmer, no need to reach for your phone.

There's one more thing this dimmer does something most people don't even know they need.
RippleShield™ Technology

The flicker you didn't know was there. Gone.

The problem most people live with

Electricity networks in NSW and south-east Queensland inject a signal into the grid to control off-peak hot water systems; it's called ripple control. Off-grid and solar systems can produce a similar effect. This signal causes many dimmable LEDs to flicker, a rapid, visible-to-the-eye pulsing at certain times of night when the tone is issued by electrical supply authortities Headaches, eye strain, and general discomfort are common symptoms. Most people assume it's normal and just live with it.

📍 NSW
📍 South-East QLD
☀️ Off-grid & solar nationally
PIXIE is the only smart home dimmer in Australia with built-in RippleShield technology, designed specifically to eliminate this problem. No filters. No workarounds. Your electrician swaps in the dimmer. The flickering stops. It's that straightforward and it comes as part of the same device that delivers your HCL lighting.

Nowhere is this more important than aged care
PIXIE HCL Human Centric Lighting in an aged care environment
Aged Care Application

Not just comfort. Better outcomes.

Nowhere is the quality of light more consequential than in aged care. Australian operators are increasingly specifying HCL, and the clinical evidence is compelling.

Circadian-aligned lighting supports natural sleep cycles, which is especially significant for residents with dementia. Appropriate light exposure in the morning has been shown to reduce sundowning; the agitation and confusion that often worsens in late afternoon. Better sleep means better days, for residents and for the people caring for them.

Improved sleep quality

Circadian-aligned light supports melatonin production in the evening, helping residents settle naturally.

Reduced sundowning

Morning bright light therapy is associated with reduced afternoon agitation in dementia patients.

Automated — zero staff burden

Once scheduled, HCL runs automatically. Staff don't need to manage or adjust lighting manually.

Mid-market capability at aged care scale. PIXIE brings clinical-grade HCL to aged care facilities without specialist programming, proprietary hardware, or the costs associated with high-end building automation. Your electrical contractor handles specification and installation through existing wholesaler channels.
