The Domus BLISS-10 is a 10W flat-face LED downlight in black or white 800lumens, IP54, a 120 beam,switchable 3000K / 4000K / 5700K, only 33.5mmdeep, and a five-year warranty.

A 120 beam the widest downlight in this range, andthat changes how many you need.

Fewer fittings for the same coverage which on a whole-house job is a realsaving in both product and installation. The trade is that a 120 beamthrows light everywhere, including at you: it is a general wash, not an accent, and itis the least directional fitting here.

The top setting is 5700K, not 5000K

Our record says 5000K; the datasheet says 5700K, which iscolder and bluer. It is set on a dip switch at the back, beforeinstallation, and cannot be changed afterwards.

• 3000K bedrooms and living rooms.
• 4000K the default: kitchens, hallways, laundries, studies.
• 5700K garage and workshop territory.

IP54 dust protection, and why that outlasts everything else

Most general-purpose downlights are IP20 indoor and dry only. IP54 addsdust protection and splash resistance from any direction:

• Dust cannot accumulate inside the lens, which is what actually dims a downlightover ten years in an Australian house.
• Usable in a bathroom outside the shower zone, a laundry or acovered outdoor ceiling subject to your electrician and AS/NZS3000.

Flat face and an opal diffuser

• The flat face nearly disappears switched off you see a ring and littleelse.
• The opal diffuser spreads the source, so despite the flat fascia there is nosingle bright point to look at. That combination flat and diffused is morecomfortable than a flat fitting with a clear lens.
• At 33.5mm it is among the shallowest here, second only to the TEK’s31mm.

Polyamide, not aluminium

The body is polyamide an engineering nylon where most downlightshere are aluminium. That is a deliberate cost decision in a range the manufacturer describes asincorporating cost saving materials.

• It cannot corrode, which is a genuine advantage in a bathroom or acoastal-adjacent house.
• Polymer conducts heat less well than aluminium, and heat is what shortens LEDlife. Domus specify a thermal management system in this range for exactly thatreason and the 40,000-hour life, against 50,000 for the aluminium ranges, iswhere the difference shows.

The numbers

• 750lm at 3000K, 780lm at 4000K, 800lm at 5700K.
• 78lm/W, CRI 83 slightly better colour than theCRI80 typical of this class.
• Cutout 90mm, face 110mm, height33.5mm.
• Fully dimmable with a suitable dimmer; dimmable driver and flex-and-plugsupplied.

Five-year warranty longer than the three years most ofthis catalogue carries, and correctly recorded here, which is not true of every value range in thiscatalogue.

Where it works

• General room lighting throughout a house about 2.5m apart, so fewer fittings.
• Bathrooms outside the shower zone, laundries and covered ceilings IP54.
• Shallow ceilings 33.5mm.
• Not an accent light a 120 beam lights everything.
• 40,000 hours, not 50,000.

Questions

How far apart should I space them?

About 2.5 metres from a 2.4m ceiling further than anything else here. The 120 beam is the widest in the range, so you need fewer fittings for the same coverage, which on a whole-house job is a real saving in both product and installation. The trade is that it throws light everywhere including at you: it is a general wash, not an accent.

Is the top setting 5000K?

No 5700K, which is colder and bluer. Our record says 5000 and the datasheet says 5700, so we have published 5700. It is set on a dip switch at the back before installation and cannot be changed afterwards, so decide first.

What does IP54 give me over a standard downlight?

Most general-purpose downlights are IP20 indoor and dry only. IP54 adds dust protection and splash resistance. Dust is the practical one: it cannot accumulate inside the lens, which is what actually dims a downlight over ten years. It also makes it usable in a bathroom outside the shower zone, a laundry or a covered outdoor ceiling, subject to your electrician.

Is the plastic body a problem?

It is a trade, and worth understanding. Polyamide cannot corrode, which is a genuine advantage in a bathroom or a coastal-adjacent house. But polymer conducts heat less well than aluminium, and heat is what shortens LED life which is why Domus specify a thermal management system in this range, and why the life is 40,000 hours against 50,000 for the aluminium ranges.

Is it comfortable to look at?

More so than most flat-faced fittings. The flat face nearly disappears when switched off, and the opal diffuser spreads the source so there is no single bright point that combination is easier on the eye than a flat fitting with a clear lens.

Will it fit a shallow ceiling?

Yes 33.5mm, among the shallowest here, second only to the TEK at 31mm.

What is the warranty?

Five years longer than the three most of this catalogue carries, and correctly recorded on this product, which is not true of every value range here.
