The Domus Cell 13 is a 13W tiltable LED downlight fiveswitchable colour temperatures, dimmable, IP44, into a8095mm cutout.

Its cutout range is unusually wide and that is the reason to choose it

• Published cutout: 8095mm. That is a 15mm span, where the deep-set version of the same fitting publishes 9092mm a 2mmspan.
• On a retrofit that difference decides the job. An older ceiling often hasholes anywhere between 80 and 95mm cut by hand, cut for a differentfitting, or enlarged when something failed. This one covers all of them; the deep-setversion does not.
• So if you are replacing an unknown or inconsistent set of downlights, this is theversion. If you are cutting fresh holes at 90mm, either works and the deep-set onegives better glare control.
• Same light engine either way the same 13W COB, the same fivecolour temperatures, the same output figures.

Five colour temperatures, five outputs

A 17% spread from the same 13W so design on the setting theroom will actually use, not the headline figure.

The published specification

Where it works

• Retrofits into unknown or inconsistent apertures the 15mm spancovers them.
• Wall-washing and feature lighting it tilts.
• Bathrooms and ensuites IP44.
• Not the first choice for glare control take the deep-set version.
• Not counted toward a floor lux level when tilted.

Questions

What is the difference between this and the deep-set version?

The housing, and the cutout it fits. This one publishes 80 to 95mm a 15mm span where the deep-set version publishes 90 to 92mm, a 2mm span. The light engine is identical: the same 13W COB, the same five switchable colour temperatures and the same output figures. So the choice is about the hole and the glare control, not the light.

Why does the cutout range matter so much?

On a retrofit it decides the job. An older ceiling often has holes anywhere between 80 and 95mm cut by hand, cut for a different fitting, or enlarged when something failed. This one covers all of them; the deep-set version does not. If you are replacing an unknown or inconsistent set of downlights, this is the version to specify.

When should I take the deep-set version instead?

When you are cutting fresh holes at 90mm and glare control matters. Deep-set recesses the LED further into the housing so the source is not visible at normal viewing angles worth having in a bedroom, a media room or anywhere people look up. With a known 90mm aperture both fittings work, so the deep-set one is the better choice there.

Does the output change with the colour temperature?

Yes: 1002 lumens at 2700K, 995 at 3000K, 1098 at 4000K, 1163 at 5000K and 1145 at 5700K a 17% spread from the same 13W. Design on the setting the room will actually sit at rather than the headline figure. The peak is at 5000K, not at the top of the range.

Can I use it in a bathroom?

Yes IP44, suitable for a bathroom ceiling outside the immediate shower zone. Check the zone requirements for your specific position, since IP44 covers splashing rather than direct jets.

Is it dimmable?

Yes. Tell us the dimmer you plan to use and we will confirm compatibility switchable-CCT downlights are sometimes fussier about dimmer type than single-temperature ones, because the driver has extra work to do.

Can I count tilted fittings toward a lux level?

No tilting moves the light off the horizontal plane, so a tilted downlight contributes much less to a floor-level reading than a fixed one. Plan the general lighting with fixed fittings and treat the tilted ones as accent.
