Illume Skylight Pros and Cons: An Honest Guide for Sunshine Coast Homes

An Illume is not a window to the sky, and it is not just a light fitting either. It is a solar-powered skylight alternative with real strengths and a few honest limits. This guide lays out both, compares an Illume with a plain LED panel light, and says who it is not for. Sol Coast Construction is an accredited Illume dealer installer on the Sunshine Coast, and Illume-only, so we see the trade-offs every week.

What an Illume is, in one paragraph

A compact solar panel sits on the roof and feeds a slim LED panel set flush in the ceiling. The panel comes on with the sunrise, holds full brightness through the day and fades at dusk, so the room reads as though it had a skylight overhead. The roof is never cut: on a Colorbond roof the only hole is a 13 mm cable hole, grommeted, siliconed and shielded by the solar panel itself; on a tiled roof the brackets slide under the tiles. The full description is on our Illume skylight alternatives page.

The pros

• No roof cutting, so nothing to leak. No opening, no shaft, no flashing to hold for decades in coastal weather. This is the reason most Sunshine Coast homeowners choose Illume over a roof window.
• No heat. The LEDs are low-powered and make no heat of their own, and nothing is conducted in from the roof. A glass skylight can turn a room into a hot box in January; an Illume cannot.
• Rooms a skylight can never reach. A ground-floor room with a bedroom above it, the hallway down the middle of the house, an internal bathroom, a walk-in robe, a garage. If the roof line, the beams or the plumbing stop a traditional skylight, an Illume still goes in.
• No wiring and nothing on your power bill. A standard Illume runs purely from its own solar panel. There is no mains connection, no battery to replace, and a standard install needs no electrician.
• Light that follows the day. Illume's Ambient Light Technology tracks the light outside, so the panel is soft in the morning, bright at midday and fades at dusk. It behaves like a skylight, not like a switch.
• Nothing to maintain. It is a sealed unit: no glass to clean, no dome to yellow, no tube for dust, bugs or condensation to collect in.
• One collector, many rooms. A single roof-mounted solar panel can feed up to nine Illumes, so a hallway, a kitchen and a dining room can share one discreet collector on the north side of the roof.
• Australian made, with a warranty. Illume is designed and made in Australia by Kimberley Products and carries a five-year manufacturer's warranty. We warrant the installation as a QBCC-licensed contractor.

The cons

We would rather you hear these from us than discover them after the install.

• It is not natural light. You get daylight-style LED light that rises and falls with the sun, not a view of the clouds. If seeing the sky matters to you and the room sits directly under the roof, a roof window is the honest answer, and we will tell you so.
• It is off at night, unless you add the AC driver. A standard Illume fades out at sunset. An AC driver add-on connects it to mains power, usually through an existing downlight's 413 socket, so it works from the same wall switch as your downlights. If there is no socket nearby, an electrician installs one.
• It is on whenever the sun is, unless you add the dimming kit. For a bedroom where you want a sleep-in, or a media room, the optional remote dimming kit lets you dim it or switch it off. It resets each morning and comes back on with the sunrise.
• Dull days are dimmer. On an overcast or rainy day the output drops to around 60 per cent. The rest of the house is darker too, so the Illume room still reads as the bright one, but it is not full brightness.
• There is no shelf price. Illume is priced by panel size and quantity, with discounts for multiples, and we quote after a site visit rather than publish a number that will not match your rooms. Our sizes guide shows which panel suits which room, but the dollars come with the quote.
• It is a sized, placed product, not an impulse buy. The panel is matched to the floor area it lights, the ceiling type decides whether it recesses or surface-mounts, and the solar panel has a best position on the roof. We work all of that out at the site visit, which is why the install is quick once it is booked.

Illume vs an LED panel light

The fair question, and the one we hear most often: if it is an LED panel in the ceiling, why not fit a plain LED panel and save the roof work?

The difference is the behaviour, not the hardware. An LED panel gives the same flat light at 7 am, noon and midnight, and the room never stops looking artificially lit. An Illume changes through the day the way a skylight does, which is what makes a windowless hallway or bathroom feel like it has one. It also needs no wiring and costs nothing to run.

An LED panel is the better answer when a room is used mostly after dark, or when you need constant light for work no matter the weather. For a pantry or a hallway you want lit day and night, the Illume with the AC driver does both jobs from one fitting.

Who an Illume is right for, and who it is not

Right for you if: the room cannot take a roof window (another floor above it, a hallway, an internal bathroom or robe, a garage), you want no roof cutting, you want no heat in summer, or you want a skylight look with nothing to clean or maintain.

Not for you if: you want to see the sky, you want the room lit at night and would rather not add the AC driver, or you need guaranteed full brightness on grey days. In those cases a roof window, a solar tube or a conventional light may suit you better. Our best skylight for a Sunshine Coast home guide compares all three.

Pros and cons questions, answered

Is an Illume skylight worth it?

Short answer: For a room a roof window cannot reach, or a home where cutting the roof is off the table, yes. For a room directly under the roof where you want the sky itself, a roof window may suit you better.

Detailed: The value of an Illume is in the rooms it opens up: hallways, internal bathrooms, ground-floor rooms under a second storey, robes and garages. It brings the look and the daily rhythm of a skylight there with no roof cutting, no heat, no wiring and nothing to maintain, backed by a five-year manufacturer's warranty. If none of that applies to your room, we will say so at the site visit.

What are the disadvantages of an Illume skylight?

Short answer: It is not real daylight, it is off at night without the AC driver, and it drops to around 60 per cent on dull days.

Detailed: An Illume gives daylight-style LED light rather than a view of the sky. Out of the box it runs from sunrise to sunset only, so night use needs the AC driver add-on and dimming needs the remote kit. On overcast days its output falls to around 60 per cent. None of these surprise anyone who has read this page, which is why we put them here.

Is an Illume just an LED light?

Short answer: No. It is solar-powered, needs no wiring, and its light rises and fades with the sun instead of staying constant.

Detailed: The panel in the ceiling is LED, but everything around it is different from a light fitting. It runs from its own solar panel with no mains connection and no battery, Ambient Light Technology tracks the daylight outside, and it switches itself on at sunrise and off at dusk. A room with an Illume reads as a room with a skylight, not a room with the lights on.

Does an Illume skylight need an electrician?

Short answer: Not for a standard install. Only the optional AC driver for night use connects to mains power.

Detailed: A standard Illume runs purely from its roof-mounted solar panel, so the installation is carpentry, not electrical work. If you want the panel to run at night, the AC driver connects it through a 413 socket, usually an existing downlight's. Where no socket is nearby, an electrician installs one.

Can an Illume replace my downlights?

Short answer: In a hallway or pantry with the AC driver fitted, one Illume can serve as both the day and night light. In most rooms it sits alongside your existing lighting.

Detailed: With the AC driver, an Illume works from the same wall switch as your downlights after dark, which is why hallways and pantries often end up with one fitting doing both jobs. Living rooms, kitchens and bedrooms usually keep their task and mood lighting for the evening and gain the Illume for the day.
