The Domus NOVA-24 Surface Mounting Profile is a surface-mountedaluminium LED profile 23.5mm wide, 11mm high, with aflat opal PMMA diffuser, in three finishes, 2.5m.

Of the two NOVA-24 listings sharing one width, this is the one it fits

• Both the recessed and the surface NOVA-24 listing publish 23.5mm. They cannot both be right, because a recessed profile carries a FLANGE and a surface one doesnot.
• The evidence points at this listing being the correct one. On theNOVA-17, the surface profile is 17mm exactly the number in the range name and therecessed one is 23mm, 6mm wider for the flange. Here 23.5mm sitsright beside the 24 in the range name, exactly as the pattern predicts for a SURFACE profile.
• So this page’s dimension is usable, and the recessed listing’s is not. Offered as reasoning from the family pattern, not as a Domus statement.
• The practical upshot is reassuring: on a surface profile the width is not a routingdimension anyway. You are fixing to a face, not cutting into one so even if it were a half-millimetre out, nothing is permanent. It is therecessed version where the same uncertainty has consequences.

The widest Domus strip channel

At 24mm nominal this is the widest of the Nova and Omega profiles against 17mm on the Nova-17 and Omega-17, and 20mm on the Nova-20. Width decides which strip fits, and a wider channel accepts a wider strip which generally means more LEDs per metre, more output, and more choice of product. The cost is a broader visible line, which on a delicate shelf edge can read asheavy. At 11mm deep it also blends well, so a wide channel and good mixing cometogether here.

And the length is published as 2.5mm

It is 2.5 metres. Six Domus products carry the same unit error, and it isnot consistent the BLOC-42 and CURVE profiles publish 2500mm forthe same real length.

This listing has the datasheet

NOVA-24 is sold under two product categories. The listings with order codesand diffuser choices carry no datasheet; this one and its recessed twin do. So thedimensions here are the authoritative ones which is exactly why the recessedtwin sharing them is a problem.

The specification

Where it works

• Where a wider, brighter strip is wanted the widest channel offered.
• Under-bench, shelving and pelmets.
• Retrofit no routing, so the width question is harmless here.
• Not on a delicate shelf edge the line reads broad.
• Not without a strip and driver.

Specifying it

Surface-mounted LED mounting profile. 23.5mm wide 11mm high, 2.5m. Flat opalPMMA diffuser. Aluminium, black or white. For the Domus IP54 strip range. Order code LP-2410-SM. BOTH NOVA-24 LISTINGS PUBLISH 23.5mm AND THEY CANNOT BOTH BE RIGHT and the evidence points atTHIS one being correct. On the NOVA-17 the surface profile is 17mm, exactly the range name, with therecessed 6mm wider for the flange; here 23.5 sits right beside the 24, exactly as the pattern predicts fora surface profile. And on a surface profile the width is not a routing dimension anyway, so nothing hereis permanent it is the recessed version where the same uncertainty has consequences.

Questions

Both NOVA-24 listings say 23.5mm which is right?

This one, on the evidence. They cannot both be right, because a recessed profile carries a flange and a surface one does not. On the NOVA-17 the surface profile is 17mm exactly the number in the range name and the recessed one is 23mm, 6mm wider for the flange. Here 23.5mm sits right beside the 24 in the range name, exactly as the pattern predicts for a surface profile.

How much does that uncertainty cost me here?

Nothing, and that is the reassuring part. On a surface profile the width is not a routing dimension you are fixing to a face rather than cutting into one, so even if it were half a millimetre out nothing is permanent. It is the recessed version where the same uncertainty has real consequences, because a groove cannot be un-cut.

Why choose the NOVA-24 over the narrower profiles?

Width. At 24mm nominal this is the widest of the Nova and Omega profiles, against 17mm on the Nova-17 and Omega-17 and 20mm on the Nova-20. Width decides which strip fits, and a wider channel accepts a wider strip which generally means more LEDs per metre, more output, and more choice of product.

Is there a downside to the width?

A broader visible line, which on a delicate shelf edge can read as heavy. If the joinery is fine and the lit line is meant to be a detail rather than a feature, a Nova-17 or Omega-17 at 17mm sits better. If the run is doing real work, the wider channel is the better starting point.

Does it blend well?

Yes at 11mm deep it sits in the useful middle for blending, so a wide channel and good mixing come together here. Depth is what turns a row of separate LEDs into a continuous line, and 11mm is enough for a normal-density strip behind an opal diffuser.

The length says 2.5mm is that right?

No, it is 2.5 metres. Six Domus products carry the same unit error, and it is not even consistent: the BLOC-42 and CURVE profiles publish “2500mm” for the same real length. Two units in one field in one category.

Why buy from this listing rather than the other NOVA-24 pages?

For the datasheet. NOVA-24 is sold under two product categories: the listings with order codes and diffuser choices carry no datasheet, while this one and its recessed twin do. So the dimensions here are the authoritative ones which is exactly why the recessed twin sharing them is a problem worth flagging.
