The Domus LP-1707-DIFF is a replacement diffuser for theNova-17 and Omega-17 profiles sold per metre, inopal or black.

Why one diffuser fits two different profiles

• Nova-17 is 17 7mm. Omega-17 is 17 15mm. They share thesame 17mm WIDTH and differ only in DEPTH.
• A diffuser slides into a channel across its width depth isbehind it and does not touch it. So one 17mm diffuser serves both, which is whythis part is sold against both names.
• That is a genuinely useful thing to know: it means a damaged diffuser on either profile isone part number, and it means you can change the LOOK of an installed run withouttouching the extrusion.

What you can change after installation and what you cannot

• So the diffuser is the cheap, reversible half of the decision ifyou fit opal and find the white line too present when it is off, this part changes it.
• What it cannot fix is dotting, because that is set by the depth betweenthe LEDs and the diffuser a Nova-17 at 8mm and an Omega-17 at 15mmbehave differently with the same strip and the same diffuser.

A note on this listing’s own text

Its order code is LP-1707-DIFF the Nova-17 code but its description introducesthe LP-1715-SM profile system. That is the Omega-17: 17 15mm. So the body is describing one of the two ranges the part genuinely fits but it is the one NOT named in its own code, and it never mentions the other. A reader arriving from a Nova-17 page finds a description of a different profile and noreassurance the part is right. It is: it fits both.

The specification

Made to order, cut to length

No lead time is published. Call our team to confirm. We will. Measure the run before ordering a diffuser cut short cannot belengthened.

Where it works

• Replacing a damaged diffuser one part for two profiles.
• Changing opal to black on an installed run.
• Spares the part most likely to be marked during a fitout.
• Not a fix for dotting that is set by the profile depth.
• Not a profile diffuser only.

Specifying it

Replacement flat PMMA diffuser, opal or black, sold per metre and cut to length. Fits Nova-17(17 7mm) and Omega-17 (17 15mm). Order code LP-1707-DIFF. ONE DIFFUSER FITS BOTH BECAUSE THEY SHARE A 17mm WIDTH AND DIFFER ONLY IN DEPTH a diffuserslides in across the width, and depth sits behind it. THAT MAKES THIS THE CHEAP, REVERSIBLE HALF OF THEDECISION: opal to black on an installed run is this part alone. WHAT IT CANNOT FIX IS DOTTING, which theprofile depth sets. Note the description here introduces the LP-1715 (the Omega-17) though its own code isthe Nova-17’s it fits both.

Questions

How can one diffuser fit two different profiles?

Because Nova-17 and Omega-17 share the same 17mm width and differ only in depth 7mm against 15mm. A diffuser slides into a channel across its width, and the depth sits behind it without touching it. So one 17mm diffuser serves both, which is why this part is sold against both names.

What can I change after installation?

The diffuser and the strip. The diffuser slides out, so opal to black or a damaged one to a new one is this part alone. With the diffuser out, the strip can also be changed for a brighter or different-colour one. What you cannot change is the profile finish, the routed groove, or the depth.

Can this fix a run that shows dots?

No, and that is the important limit. Dotting is set by the depth between the LEDs and the diffuser a Nova-17 at 8mm and an Omega-17 at 15mm behave differently with the same strip and the same diffuser. Changing the diffuser changes the look and the output, not the blending distance.

Which should I choose, opal or black?

Black if the off state matters it reads as a dark line rather than a white stripe, which in a dark ceiling or cabinet is the whole point. Opal if output matters, since the tint absorbs light. Domus does not publish how much, so if the run is doing real work rather than decorating, opal is the safer choice.

Why does the description talk about a different profile?

Its order code is LP-1707-DIFF the Nova-17 code but the description introduces “the LP-1715-SM profile system”, which is the Omega-17 at 17 x 15mm. So the body is describing one of the two ranges the part genuinely fits, but it is the one not named in its own code, and it never mentions the other. A reader arriving from a Nova-17 page finds a description of a different profile and no reassurance the part is right. It is it fits both.

Is this a good thing to keep as a spare?

Yes. The diffuser is the part most likely to be marked or damaged during a fitout it is plastic, it is the exposed face, and it goes in before the rest of the trades finish. One spare metre covers both profile families, which makes it an unusually efficient thing to hold.

Anything to watch when ordering?

Measure the run first. It is cut to length and a diffuser cut short cannot be lengthened, so the measurement matters more than usual on a part with no adjustment in it. No lead time is published, so call us to confirm before ordering.
