The HV10592T is the four-lamp Luz in solid brass two GU10 globes up, two down, in the wider of the two Luz bodies. It is the flagship of the range and the one where the choice of material is doing most of the work, because the electrical specification is identical to the black and white versions and the price is not.

The material is the reason to buy it

Havits siting clause for this range reads: aluminium and 304SS fittings must not be installed within 5km of any salt water environment. That clause names aluminium and 304 stainless steel. It does not name solid brass and for a coastal or estuarine address that absence is usually the entire specification argument. We are careful here: no Havit document publishes a salt-water distance for solid brass, so we state the clauses scope and decline to invent a figure for this fitting in either direction.

Brass has its own conditions instead, and they are published. Solid brass tarnishes naturally outdoors Havit says so on both of this products documents, and it is normal ageing rather than a defect. Havit also asks that gloves be worn during installation so that skin oils do not transfer to the metal and set as marks under the developing patina. On four lamp heads, that is worth remembering before you handle it.

Four lamps, and what they actually give you

Havit supplies four 9-in-1 tri-colour GU10 globes. Output is quoted per lamp: 240560lm at 3000K, 255595lm at 4000K and 270630lm at 5500K, across each globes 3W, 5W and 7W settings, and output rises with colour temperature, so 5500K at 7W is the brightest available. Per lamp that is identical to the two-lamp HV10591T: the four-lamp body covers a wider pier, it does not light the same pier harder. Beam is 60, from the globe rather than the housing, and Havit presets every fitting to 3000K at 7W a warm setting that suits brass particularly well.

Install, sealing and electrical

Fix the backing plate and then seal every hole including the cable entry and screw holes; Havit states that failing to do so voids the warranty, along with a missing seal or o-ring or any modification. Rated IP65 and IK10 behind clear glass, it is 240V AC mains with no driver or transformer and Class1, so an earth is required. The four GU10 holders are replaceable to 35W each, giving 4 35W. Height is 300mm, with a 60mm aperture at each lamp position and a base plate taking four 4mm fixings around a 13mm cable entry. Width and wall projection are not published, because Havits drawing does not label them.

It is Triac dimmable using the HV9625 300W dial dimmer. At this price point Lights For You would rather you asked us first we will go through the brass, the siting and the sizing with you before anything is ordered.

Questions

Is the brass Luz suitable for a beachfront property?

Havits exclusion for this range covers aluminium and 304SS fittings within 5km of salt water, and this fitting is solid brass, which the clause does not name. We do not publish a distance for solid brass because Havit does not publish one. What Havit does publish is that solid brass tarnishes naturally outdoors, which in a marine atmosphere will happen faster.

Why is it so much more expensive than the black version?

The material. Electrically and dimensionally the four-lamp brass Luz and the four-lamp black Luz are the same fitting same GU10 holders, same globes, same 240V mains, same IP65 and IK10 ratings, same 300mm height. The difference is solid brass rather than powder coated aluminium, and the siting clause that follows from it.

Does the four-lamp version give more light than the two-lamp?

More coverage, not more light per direction. Each globe is identical, at 240560lm. Four lamps spread the effect across a wider pier; if you want a stronger effect in one place, run the two-lamp versions globes at 7W.

Are the globes included?

Yes four 9-in-1 tri-colour GU10 globes, listed in this models data sheet Included LED column and stated on Havits own page for it. Each is switchable between 3000K, 4000K and 5500K and between 3W, 5W and 7W.

Do I need gloves to install it?

Havit asks for them. Its instructions say that when installing copper or brass fittings, gloves must be worn to avoid oils transferring to the fitting fingerprints laid down before the brass starts ageing tend to stay visible.

Which colour temperature suits brass best?

That is a judgement rather than a specification, but 3000K is the setting Havit ships it on and the one most people keep, because warm light flatters the metal. If you want maximum output instead, 5500K at 7W is the brightest at 630lm per lamp.

What voids the warranty?

Not sealing the backing plate cable entry and screw holes included leaving an o-ring or seal out of place, or modifying the fitting. Havit states this explicitly. Natural tarnishing of the brass is not a defect and not a warranty matter. The warranty is 3 years replacement for items ordered after 01/01/22.
