The Domus SHADOW 1LT ADJ is an adjustable exterior wall light 240V GU10, IP65, 90 tilt and 270 swivel,8080175mm, in white with a choice oftricolour, 3000K or 5000K lamp.

Two wattages, both correct, meaning different things

• The datasheet says 35W Max. The product record says10W. Neither is wrong.
• 35W is the holder’s ceiling the most a GU10 lamp may draw inthis fitting without overheating it. 10W is the lamp actuallysupplied.
• WE CHECKED HOW WIDESPREAD THAT IS: 21 products publish a metafield wattagewhere their sheet figure is explicitly a Max. GU10 fittings read35W Max against a 10W field; E27 fittings read 60W Maxagainst 25W.
• SO THE FIELD IS NOT COMPARABLE ACROSS PRODUCTS. On one listing it iswhat the fitting will accept; on another it is what arrives in the box. Anyone filtering or comparing on wattage is comparing two different quantities.
• WHAT TO USE EACH FOR: size the circuit on 35W if you might fit a brighter lamp later;expect 10W of light from what arrives.

Three lamp choices, and the tricolour is the one to think about

• The variants are a tricolour lamp, a fixed 3000K anda fixed 5000K.
• TRICOLOUR IS USUALLY THE RIGHT CHOICE OUTDOORS, because the correctcolour temperature for a facade is very hard to judge from a drawing and easy to judge at night against theactual material. Warm flatters brick, timber and planting; cooler gives definition onrender and better camera clarity.
• The fixed lamps are worth taking when the answer is already known matching anexisting installation, or a specification that names a temperature.
• WHICHEVER YOU CHOOSE, SET EVERY FITTING ON ONE ELEVATION THE SAME. Mixed colour temperatures across a facade read as a fault rather than a choice, and it is themost common thing to get wrong with switchable lamps.

80 80 175 mm small, and that is the point

An 80mm square face projecting 175mm. On a facade that reads asa small dark block rather than a fitting which is what you want when the effectshould be visible and the source should not. It also means the fitting suitsnarrow piers, window reveals and the space between openings, where a larger body would lookcrowded. Check the projection against anything that opens: 175mm is enough tocatch a casement or a gate.

IP65 and what it covers on a wall

IP65 is dust-tight and protected against water jets from any direction. On a wall that covers driving rain, hosing and run-off which is the whole realisticexposure for a facade fitting. What it does not cover is immersion, soit is not a fitting for a position that can flood or sit under a downpipe outlet. The seal is only as good as the installation: a fitting mounted on an uneven surface without agasket seated properly is IP65 on paper and not in practice.

What is published

Where it works

• Facades, piers, window reveals a small dark block.
• Positions whose aim is not certain tilt and swivel.
• Where the colour is best judged at night tricolour.
• Not where it can flood IP65 is not immersion.
• Not near anything that opens 175mm projects.

Specifying it

Adjustable exterior wall light, IP65. 240V GU10, 35W maximum holder rating,10W lamp supplied. 90 tilt, 270 swivel. 80 80mm face, 175mm projection. Tricolour,3000K or 5000K lamp. White. 3-year warranty. ITS SHEET SAYS 35 W AND ITS RECORD SAYS 10 W, AND BOTH ARE CORRECT 35 W is the holder’sceiling and 10 W is the lamp supplied. 21 products in this catalogue publish a lamp figure where the sheetfigure is a “Max”, so the wattage field is not comparable across products: on one listing it is what thefitting will accept, on another what arrives in the box. SIZE THE CIRCUIT ON 35 W IF YOU MIGHT FIT ABRIGHTER LAMP LATER; EXPECT 10 W OF LIGHT FROM WHAT ARRIVES.

Questions

Is it 35W or 10W?

Both, and they mean different things. 35W is the holder’s ceiling the most a GU10 lamp may draw in this fitting without overheating it. 10W is the lamp actually supplied. Size the circuit on 35W if you might fit a brighter lamp later, and expect 10W of light from what arrives.

Is that confusing across the catalogue?

It can be. 21 products publish a metafield wattage where their sheet figure is explicitly a “Max” GU10 fittings read 35W Max against a 10W field, E27 fittings 60W Max against 25W. So the wattage field is not comparable across products: on one listing it is what the fitting will accept, on another what arrives in the box.

Which lamp option should I take?

Tricolour, usually. The correct colour temperature for a facade is very hard to judge from a drawing and easy to judge at night against the actual material warm flatters brick, timber and planting, cooler gives definition on render and better camera clarity. The fixed 3000K and 5000K lamps are worth taking when the answer is already known: matching an existing installation, or a specification that names a temperature.

What is the most common mistake with switchable lamps?

Mixing them. Set every fitting on one elevation to the same setting mixed colour temperatures across a facade read as a fault rather than a choice, and it is easy to do by accident when fittings are commissioned on different days.

How big is it?

An 80mm square face projecting 175mm. On a facade that reads as a small dark block rather than a fitting, which is what you want when the effect should be visible and the source should not. It also suits narrow piers and window reveals where a larger body would look crowded. Check the projection against anything that opens 175mm is enough to catch a casement or a gate.

What does IP65 cover?

Dust-tight and protected against water jets from any direction, which on a wall covers driving rain, hosing and run-off the whole realistic exposure for a facade fitting. What it does not cover is immersion, so it is not a fitting for a position that can flood or sit under a downpipe outlet.

Does the installation affect the rating?

Yes. The seal is only as good as the installation a fitting mounted on an uneven surface without its gasket seated properly is IP65 on paper and not in practice. On rendered or rough brick it is worth checking the mounting face is flat, or packing it so the gasket compresses evenly.
