The Domus BOOST-10 is a 10W recessed LED downlight with ananti-glare deep-set frame and an opal diffuser, IP54, switchable3000K / 4000K / 5700K, in black or white.Cutout 90mm.

Five-year warranty, and it is properly recorded. That isworth saying plainly because it is unusual in two directions: most of this catalogue carriesthree years, and several other Domus downlights that do carry five have lostthe figure somewhere between the datasheet and the product page.

Over a ceiling full of fittings, five years against three is a real difference and replacing a failed downlight is a labour job, not a parts job.

What BOOST is and is not

Domus describes this range plainly: it uses cost-saving materials to produce a cost-effective,well-performing downlight. That is an honest description and worth repeating rather thandressing up.

• It keeps the things that matter the deep-set anti-glare frame, the opaldiffuser, an integrated dimmable driver with flex and plug, IP54, and colour switching.
• The body is polyamide rather than die-cast aluminium. That is the cost saving,and it is the honest trade-off: lighter, cheaper, and it relies on the range’sthermal management system rather than on a metal heatsink.
• Where it belongs is a whole-house fit-out at a sensible price, not a specificationjob where die-cast aluminium is called for.

The numbers

• 750lm at 3000K, 780lm at 4000K, 800lm at 5700Kfrom 10W.
• 90 beam wider than the usual 60, so it covers more floor perfitting and needs fewer of them.
• CRI 83. An oddly precise figure where most of this catalogue says 80 anda genuine, if small, step up.
• 90mm cutout, 110mm face, 40mm deep. The cutout ison the datasheet and in no product field.
• 40,000hours, fully dimmable with suitable dimmers.

Why the deep-set frame matters more at 90

• A wide beam means light reaching you at a shallow angle, which is exactly thegeometry that makes a flush downlight glare.
• Setting the LED back behind an opal diffuser fixes that you see a litsurface rather than a bright point.
• In an open-plan room it is the difference between a comfortable ceiling and a row ofdots in your peripheral vision.

IP54 and the colour switch

• IP54 splashing water from any direction. Bathrooms outside the shower zone,laundries, covered alfrescos, subject to your electrician and AS/NZS3000.
• Not IP65. Directly above a shower, ask us for a higher rating.
• 3000K living areas and bedrooms; 4000K kitchens,bathrooms and laundries; 5700K garages and workshops set by dip switch atthe back before the fitting goes into the ceiling.

Where it works

• Whole-house downlighting at a sensible price and a five-year warranty behind it.
• Open-plan living, where the deep frame and 90 beam work together.
• Bathrooms outside the shower zone, laundries, covered alfrescos.
• Retrofits into a standard 90mm hole.
• Not where a die-cast aluminium body is specified this one is polyamide.
• Not directly above a shower ask us for IP65.

Questions

What warranty does it carry?

Five years, and it is properly recorded on this product which is worth saying because most of this catalogue is three years and several other Domus downlights that do carry five have lost the figure between the datasheet and the page. Over a ceiling full of fittings that difference is real, because replacing a failed downlight is a labour job rather than a parts job.

What size hole does it need?

90mm, which is the standard Australian downlight cutout, so it drops into most existing installations without patching. The visible face is 110mm and it is 40mm deep. Note the cutout is on the datasheet and in no product field, so it is not there if you are planning a ceiling from the record.

What is the catch with a cost-effective downlight?

The body is polyamide rather than die-cast aluminium, and Domus is upfront that the range uses cost-saving materials. It keeps what matters the deep-set anti-glare frame, the opal diffuser, the integrated dimmable driver, IP54 and colour switching and relies on the range’s thermal management rather than a metal heatsink. For a whole-house fit-out at a sensible price that is a fair trade; for a specification job calling for die-cast aluminium it is not.

Why is the beam 90 instead of 60?

It covers more floor per fitting, so you need fewer of them across a room. The trade-off is that a wide beam reaches your eye at a shallow angle, which is exactly the geometry that makes a flush downlight glare which is why the deep-set frame and opal diffuser matter more here than on a narrow-beam fitting.

Can it go in a bathroom?

Yes, outside the shower zone. IP54 covers splashing water from any direction, which suits a bathroom or laundry ceiling and a covered alfresco, subject to your electrician and the zones in AS/NZS 3000. Directly above a shower you want IP65 and we can point you at one.

What does CRI 83 mean next to CRI 80?

A small but genuine step up in how accurately colours render. Most of this catalogue rounds to 80, so the precision of 83 is unusual and it is a real figure rather than a rounding. It is not the 90 you would specify for a display cabinet, but for general room lighting it is at the better end of ordinary.

Is it dimmable?

Fully dimmable with suitable dimmers, and the driver is already integrated with a flex and plug so there is nothing extra to fit above the ceiling. Tell us which dimmer you are using and we will confirm the pairing before you buy both.
