01Kelvin
Colour temperature
How warm or cool the light reads. Warm light in the evening (around 2700K) carries less blue content and helps support the body's natural wind-down. Cooler light in the day supports alertness.
Light, designed
for the body.
Ascentra Sol makes lighting that does more than illuminate — it looks after the people under it. We engineer light around human health: how we sleep, focus, breathe and feel.

01 Positioning Our story
Health-grade lighting
for everyday life.
The wellness benefits of light, engineered into products you actually want to live with.
Every product tunes a specific property of light — colour temperature, brightness, spectrum — into a measurable wellness benefit. That is the whole discipline: light treated as something to design for the body, not just the room.
We are equally a consultancy and a supplier. Some clients come to us for a single lamp. Others bring a whole floor, a clinic, a hotel, a home they are still building. The method is the same either way.
02 The four properties What we actually tune
Four dials,
honestly explained.
There is no magic in healthy light — only properties that can be measured, and choices that can be justified. These are the four we work with.
02Lux & lumens
Brightness
Not "more is better" — right is better. We specify output for the task and the hour, so a room can be bright enough to work in and quiet enough to settle in.
03CRI & spectrum
Spectral quality
What the light is actually made of. High colour rendering (CRI 95+) means skin, food and materials look like themselves. Low blue content in the evening means the light asks less of you.
04Circadian
Timing
Light is a signal, and signals have a clock. We shape the day — brighter and cooler when you need to be awake, warmer and lower as the evening closes.
Ascentra Sol products are designed to support comfort, rest and focus. They are not medical devices and are not intended to diagnose, treat or cure any condition.
03 Brand pillars How we behave
01
Science first
Every claim ties back to a real, measurable property of light.
02
Quietly premium
Restraint over decoration. We let the product and the glow speak.
03
Human-centred
We design for the body — rest, focus, comfort and safety.
04
Warm & honest
Health-grade doesn't mean cold. We speak plainly and kindly.
Voice & tone
We sound like a trusted specialist
who happens to be warm.
Confident about the science, never clinical about the person. Short sentences. Real benefits. No hype — and never a promise light cannot keep.
04 Questions Plainly answered
The things
people ask.
Is "health-grade lighting" a regulated term?
No — and we are careful with it. We use it to describe our own standard: every specification traces back to a measurable property of light, and we will show you the numbers behind any claim we make. Our products are not medical devices.
Do I need a consultation to buy a product?
Not at all. HaloGuard and the rest of the range can be bought on their own. The consultation exists for people who want the whole space considered rather than a single fitting.
What does a consultation cost?
It depends on the size and type of the space. We scope it after a short conversation and quote a fixed fee before any work starts — no open-ended hours.
Do you work with existing fittings?
Often, yes. The cheapest good result is usually a change of lamp, position or control rather than a full replacement. We will say so when that is the honest answer.
Do you supply trade and hospitality projects?
Yes. Premium light supply is half of what we do — from our own range and from partner manufacturers we have specified and tested. Get in touch about trade terms.
