The single-head Tivah in solid copper is the same body as the white and black versions in a material that behaves completely differently over time. One head, tilting through 90 and swivelling through 270 on a matching copper backing plate, with a high-output reflector behind the lamp.

Copper is a decision about the next ten years, not the photograph

It arrives bright and does not stay that way. Outdoors it darkens through browns within the first year, and in salt air it will eventually go green. Nothing about that is a fault it is why solid copper is specified on heritage and coastal work, where a powder-coated aluminium fitting would chalk and start to look neglected instead. Havit asks that gloves be worn during installation so that finger marks do not print into the surface before it weathers evenly. If you want the fitting to look the same in five years as it does on delivery, order the powder-coated aluminium version instead; this is not that product.

Choosing between the three part numbers

• HV1215T 240V GU10 with the 9-in-1 switchable globe. Set it to 3W, 5W or 7W at install: 240560lm at 3000K, 255595lm at 4000K, 270630lm at 5500K, in a 60 beam. Triac dimmable.
• HV1217GU10T 240V GU10 fixed at 5W: 270lm, 285lm and 300lm across the three temperatures, in a wider 120 beam. Not dimmable as supplied.
• HV1217MR16T the same output and beam at 12V DC on an MR16 base, requiring its own driver.

The practical difference between the top and bottom of that list is control. The 9-in-1 globe lets an electrician tune output on site once the fitting is up and the wall is lit, which matters more on a pillar than on a bench you rarely know how much light a surface needs until you see it.

Wiring and limits

Both GU10 versions are Class1 and wire straight to mains with an earth. The MR16 version is 12V DC: it needs an LED driver, must sit within 25m of it, and the supply must stay within 5% of nominal or the warranty is void. Maximum globe wattage is 35W on a 240V GU10 and 20W on a 12V MR16. IP65 means an exposed pillar needs no eave. Colour temperature is a switch on the globe, so one order covers warm through cool. All three carry a 3-year replacement warranty. Lights For You stocks the matching two-head and fixed-down Tivahs in solid copper if a run of pillars needs to weather at the same rate.

Questions

Will the copper stay bright?

No. It darkens through browns outdoors within about a year and can verdigris near salt air. That ageing is the reason to choose solid copper; if you want a stable colour, the powder-coated aluminium Tivah is the alternative.

What does the 9-in-1 globe in HV1215T do?

It carries switches for three wattages (3 W, 5 W, 7 W) and three colour temperatures, set during installation, so one part number covers nine combinations.

Which version is dimmable?

HV1215T, using a Triac dimmer. HV1217GU10T and HV1217MR16T are not dimmable with the globes supplied.

Do I need a driver?

Only for HV1217MR16T, which is 12 V DC. It needs a 12 V DC LED driver within 25 m, with the supply held within 5% of nominal.

What is the largest globe it will take?

35 W on the 240 V GU10 versions, 20 W on the 12 V MR16.

Why are the beam angles different between the versions?

The beam belongs to the globe rather than the housing. The 9-in-1 globe in HV1215T is a 60 optic; the fixed 5 W globes are 120. Fit a different globe and the beam changes with it.

Can I install it somewhere fully exposed?

Yes. IP65 covers dust and low-pressure water jets from any direction, so no eave or hood is required.
