The Domus GTA-161 is a replacement panel set for the CHESTER LARGEseries a full set of diffuser panels supplied together, made to order.

It publishes almost nothing, and that is the right answer

• This product’s record carries a single field: a warranty. No voltage, no wattage, no IP rating, no lamp base, no beam angle.
• FOR A DIFFUSER PANEL SET THAT IS CORRECT, NOT A GAP. A panel is passive it has no electrical parts, so it should publish no electrical specification.
• WE MEASURED THE DISTINCTION RATHER THAN ASSUMING IT. Of50 products publishing two or fewer metafields, 14 are passive parts wherethe absence is correct and 36 are fittings where it is a real gap. Reporting 50 products with no data as one number would mix the two.
• AND THE INVERSE IS THE COMMONER FAULT HERE. Of 104passive parts in this catalogue diffusers, bases, adaptors, brackets and spares 83 carry an electrical field they cannot have. This one doesnot.
• WHAT IS GENUINELY MISSING IS THE PANEL DIMENSION. A spare panel is boughtto fit something, so its size is the specification that matters and it is notpublished. Ask us and we will confirm with Domus.

“Chester Large” identify the series and the size before ordering

• This set suits the CHESTER LARGE series, not the standardCHESTER. Domus’s traditional exterior families run a standard and a large range inparallel, with different parts.
• SO TWO THINGS HAVE TO BE RIGHT: the series and the size. A Chester panelwill not fit a Turin, and a standard Chester panel will not fit a ChesterLarge.
• IDENTIFY BY THE GT CODE ON THE FITTING, NOT BY EYE. The standard andlarge versions of one family look alike in isolation, and they usually are in isolation. The code is on the original invoice or a label inside the fitting.
• IF THERE IS NO CODE, MEASURE A PANEL AND PHOTOGRAPH THE FITTING we will confirm before you order. On a made-to-order part a wrong assumptionis ten business days each way.

A set, because panels age together

A lantern has four or more panels and they weather at the same rate UV clouds acrylicand coastal air etches glass on every face equally. SO REPLACING ONE PANEL IN AWEATHERED LANTERN LEAVES A BRIGHT FACE AMONG DULL ONES, which from a distance reads worse than the crackyou were fixing. The set solves that, and it works out cheaper across a decade one order with one lead time rather than four with four. The exception is a new lantern:if nothing has aged yet, a single panel is the sensible purchase.

Why panels beat a replacement lantern on a made-to-order range

The CHESTER fittings are made to order. THAT MEANS A REPLACEMENT LANTERNIS NOT A SHELF ITEM: ten business days, and a new finish applied to your order. A new lantern beside five that have weathered six years will not match however carefully thecolour is specified, because powder coat fades outdoors. Replacing the panels keeps theoriginal castings, the original finish and the original patina which is the thing you cannot buyback.

Acrylic and glass fail on different schedules

• ACRYLIC YELLOWS AND CLOUDS UNDER UV rather than cracking the lightoutput falls gradually, often by enough to notice long before anyone identifies thecause.
• GLASS DOES NOT YELLOW but it etches in coastal air and breaks outright.
• SO ACRYLIC IS REPLACED ON APPEARANCE AND GLASS ON BREAKAGE which means an acrylic lantern gives years of warning and a glass one givesnone.
• IF A LANTERN LOOKS DIMMER AND THE LAMP IS NEW, CHECK THE PANELS. People usually replace the lamp twice first.

Made to order

Allow up to 10 business days for production. Damage is discovered when youwant it fixed, not ten days beforehand. On a property with several CHESTER lanterns, onespare set on a shelf turns a ten-day wait into an afternoon.

What is published

Where it works

• Restoring weathered CHESTER LARGE lanterns.
• Keeping the original castings and patina.
• As a shelf spare it removes the ten-day wait.
• Not ordered without confirming standard vs Large.
• Not ordered on the listing’s dimensions there are none.

Specifying it

Replacement diffuser panel set for the CHESTER LARGE series. Supplied as a set. No electricalparts. Made to order, up to 10 business days. 1-year warranty. THIS PAGE PUBLISHES A WARRANTY AND NOTHING ELSE, AND FOR A PASSIVE PART THAT IS CORRECT RATHERTHAN A GAP a diffuser panel has no electrical parts, so it should publish no electrical specification. Wemeasured the distinction instead of assuming it: of 50 products publishing two or fewer fields, 14 arepassive parts where the absence is right and 36 are fittings where it is a real gap. AND THE COMMONERFAULT HERE IS THE INVERSE 83 of 104 passive parts in this catalogue carry an electrical field they cannothave. WHAT IS GENUINELY MISSING IS THE PANEL DIMENSION, which is the one specification a spare is boughton. Ask us.

Questions

Why does this page list almost no specifications?

Because a diffuser panel set is passive it has no electrical parts, so it should publish no voltage, wattage, IP rating or lamp base. For this kind of product an absent specification is the right answer rather than a gap.

How do you know that is deliberate rather than missing data?

We measured the distinction instead of assuming it. Of 50 products publishing two or fewer metafields, 14 are passive parts where the absence is correct and 36 are fittings where it is a real gap. Reporting “50 products with no data” as one number would mix the two.

Is anything genuinely missing here?

The panel dimension. A spare panel is bought to fit something, so its size is the specification that matters and it is not published. Ask us and we will confirm with Domus before you order.

Do most spare parts here get this right?

No, and the fault runs the other way. Of 104 passive parts in this catalogue diffusers, bases, adaptors, brackets and spares 83 carry an electrical field they cannot have. This one does not.

How do I know it fits my lantern?

Two things have to be right: the series and the size. This set suits the CHESTER LARGE, not the standard CHESTER, and Domus’s traditional exterior families run a standard and a large range in parallel with different parts. A Chester panel will not fit a Turin, and a standard Chester panel will not fit a Chester Large.

How do I tell which I have?

By the GT code on the fitting, not by eye. The standard and large versions of one family look alike in isolation, and they usually are in isolation. The code is on the original invoice or a label inside the fitting. If there is none, measure a panel and photograph the fitting and we will confirm on a made-to-order part a wrong assumption is ten business days each way.

Why not just replace the lantern?

Because you cannot buy the patina back. The CHESTER fittings are made to order, so a replacement lantern is ten business days and a new finish applied to your order and a new lantern beside five that have weathered six years will not match however carefully the colour is specified, because powder coat fades outdoors. Replacing the panels keeps the original castings, finish and patina.
