This is the double-headed Tivah in titanium-coloured aluminium: two independently adjustable heads on one backing plate, each with 90 of tilt and 270 of swivel and a high-output reflector behind the lamp. Two heads on a single wiring point is the whole argument for it one hole in the pillar, one cable, and light going up and down the wall, or two separate directions across a driveway, from a single fitting.

The choice to make

Three part numbers, and they differ electrically:

• HV1385T 240 V GU10 with switchable globes stepping through 3 W, 5 W and 7 W per head.
• HV1387GU10T 240 V GU10 at a fixed 5 W per head, giving 2 270 lm at 3000K, 2 285 lm at 4000K and 2 300 lm at 5500K.
• HV1387MR16T 12 V DC MR16 at 5 W per head with the same per-head output, requiring a 12 V DC LED driver.

Note how the output is written. The figures are per head a fitting set to 5500K produces 300 lm from each of its two lamps, which is how the datasheet states it and how it should be read when you compare it against a single-head fitting.

Where it works

• Driveway pillars, with one head washing up the pillar and the other down onto the surface.
• Between two windows on a facade, throwing symmetric scallops of light.
• Boundary and courtyard walls where a single fitting has to cover a tall span.
• Exposed positions at IP65 it does not require an eave.

Specifying it

The fitting is IP65 and surface mounts to a wall. The 240 V versions are wired to mains; the MR16 version is a low-voltage fitting that takes a 12 V DC LED driver and must not be connected to mains. Because it carries two lamps, the load on that driver is double what a single-head fitting draws size for the total, and wire multiple fittings in parallel. The datasheet limits a low-voltage fitting to 25 m from its driver with the supply within 5% of nominal, and voids the warranty outside those.

It is not dimmable with the globes supplied. Globes are replaceable and the ceilings differ by version 35 W on a 240 V GU10, 20 W on a 12 V MR16, and that is per lamp, not per fitting. The titanium finish sits between the black and the stainless in the same family, and Lights For You carries the matching single-head Tivah if an elevation needs both.

Coastal siting Havits condition

Havits installation instructions for this fitting state that aluminium and 304 stainless steel fittings must not be installed within 5 km of any salt water environment. That is a condition on where the fitting may go, and it sits beside the IP rating rather than inside it: a fitting can be rated for direct rain and still fall outside this rule, because the issue is salt carried in the air rather than water landing on the surface. If your site is inside that zone, talk to us before you specify it Lights For You can point you at a fitting whose material Havit does not name here.

Earthing and protection class

This listing sells more than one supply, and the earthing requirement is not the same on both. Check which part number you are wiring before you start.

• HV1385T, HV1387GU10T run on 240 V AC mains and are Protection Class 1 an earth is required at the fitting. Havit’s installation sheet has the installer connect the earth conductor first, then live and neutral.
• HV1387MR16T run on 12 V DC and are Protection Class 3 no earth is required at the fitting. The isolation comes from the LED driver rather than from an earth conductor, and these part numbers must never be connected directly to 240 V.

Questions

Is the lumen figure for the whole fitting or one head?

One head. The datasheet states 2 270 lm, 2 285 lm and 2 300 lm, meaning each of the two lamps produces that figure. We quote it the same way rather than adding them together.

Which part number do I need?

HV1385T for 240 V with switchable 3/5/7 W globes, HV1387GU10T for 240 V at a fixed 5 W per head, or HV1387MR16T if you are running 12 V DC.

Does it need a driver?

Only HV1387MR16T. It is 12 V DC and requires a 12 V DC LED driver, sized for two lamps per fitting. The GU10 versions run on mains.

Can it be dimmed?

No not with the globes supplied.

What is the maximum globe wattage?

35 W on a 240 V GU10 and 20 W on a 12 V MR16, per lamp. A double-head fitting therefore takes two globes at or under that figure, not one globe of twice it.

Can both heads be aimed separately?

Yes. Each head has 90 of tilt and 270 of swivel independently of the other.

Can it be mounted in the weather?

Yes. It is IP65, so an exposed wall or pillar is within its rating.

What warranty applies?

A 3-year replacement warranty.
