This is the double-adjustable Tivah in solid copper: two independently aimed heads on one backing plate, fed from a single wiring point. Unlike the up/down version, which is fixed at one head up and one down, both heads here tilt through 90 and swivel through 270 so you can point them at the same target from two angles to kill a shadow, or split them across a wide facade from one cable run.

Read the lumen figures as per head

Havit prints them as 2 for a reason. Each of the two lamps produces the stated output; the fitting does not concentrate the sum into one beam. Comparing a 2 300lm fitting against a single-head 300lm fitting on the raw number would flatter the wrong one.

• HV1315T 240V GU10 with switchable 9-in-1 globes: 2 240560lm at 3000K, 2 255595lm at 4000K, 2 270630lm at 5500K, stepping through 3W, 5W and 7W per head in a 60 beam.
• HV1317GU10T 240V GU10 fixed at 5W per head: 2 270lm, 2 285lm and 2 300lm across the three temperatures, in a 120 beam.
• HV1317MR16T the same output and beam on 12V DC MR16, requiring a driver.

What the copper does

Solid copper is not a finish, it is the material, and it will not stay the colour it arrives in. Outdoors it darkens through browns over the first year and near salt air it eventually turns green. That is the reason people specify it: unlike a coated alloy, which chalks and then looks tired, copper ages into something the client wanted. Havit asks that gloves be worn during installation so finger oils do not print into the surface before it starts to weather.

Specifying it

Both GU10 versions run on 240V mains as earthed Class1 fittings. The MR16 version is 12V DC and needs a driver and because this fitting carries two lamps, the load on that driver is double a single-head fittings, so size it for the total and run several fittings in parallel from one supply if that suits the site. Keep it within 25m of its driver and the supply within 5% of nominal. Globe ceilings are 35W per lamp on a 240V GU10 and 20W per lamp on a 12V MR16 per lamp, not per fitting, so a two-head fitting takes two globes at or under that figure rather than one of twice it. Only HV1315T is Triac dimmable. Colour temperature is set on the globe itself at install rather than chosen at the checkout. IP65 means an exposed pillar is fine. Every version carries a 3-year replacement warranty, and Lights For You can size a 12V driver for you if you tell us how many fittings share it.

Questions

Is 300 lm the output of the whole fitting or one head?

One head. Havit writes it as 2 300 lm because each of the two lamps produces that figure. We quote it the same way rather than adding them together.

How is this different from the up/down Tivah?

The up/down version has one head fixed upward and one fixed downward. On this one both heads tilt through 90 and swivel through 270, so you choose where each beam goes.

Can it be dimmed?

HV1315T is Triac dimmable. HV1317GU10T and HV1317MR16T are not dimmable with the globes supplied.

What size driver does the MR16 version need?

Size it for two lamps per fitting, not one, and multiply again by the number of fittings on that driver. It must be a 12 V DC LED driver, sited within 25 m.

Will the copper stay this colour?

No, and that is the point of it. It darkens through browns outdoors and can eventually verdigris near the coast. If you want a stable colour, the powder-coated aluminium Tivah is the version to order.

What is the maximum globe wattage?

35 W on a 240 V GU10 and 20 W on a 12 V MR16, per lamp. Two lamps at that ceiling, not one of double it.

Do I need to do anything special when installing it?

Wear gloves. Havit asks for it on copper fittings so that skin oils do not mark the surface before it begins to weather evenly.
