This is the up/down Tivah in textured white: one fitting, two heads, one washing the wall upward and one down, from a single wiring point. It is the shape most people actually picture when they think of a wall light on a pillar the symmetrical hourglass of light either side of a front door or a gate post and it produces it without two fittings and two cable runs.

Read every lumen figure as per head

Havit prints them with a 2 because each of the two lamps produces the stated output. The fitting throws light in two directions rather than concentrating the sum into one, so comparing it against a single-head fitting on the raw number would flatter the wrong one.

• HV1035T 240V GU10 with 9-in-1 switchable globes stepping through 3W, 5W and 7W per head: 2 240560lm at 3000K, 2 255595lm at 4000K, 2 270630lm at 5500K, in a 60 beam. The only Triac-dimmable version.
• HV1037GU10T 240V GU10 fixed at 5W per head: 2 270lm, 2 285lm, 2 300lm, in a wider 120 beam.
• HV1037MR16T the same output and beam on 12V DC MR16, requiring its own driver.

Choosing between the beams

On an up/down the beam angle changes the shape of the light more than its brightness. The 60 globes throw two narrow blades that read as a crisp hourglass on a flat wall; the 120 globes spread into two soft fans that overlap on a narrow pillar. On brick or stone the narrow one flatters the texture; on smooth render the wide one avoids a hard edge.

Installing it

Both GU10 versions wire straight to 240V mains as earthed Class1 fittings. The MR16 version is low voltage: it needs a 12V DC LED driver, and because this fitting carries two lamps the load is double a single-head fitting’s size the driver for the total, keep it within 25m, and hold the supply inside 5% of nominal or the warranty is void. Globes are replaceable to a ceiling of 35W per lamp on a 240V GU10 and 20W per lamp on a 12V MR16 two globes at that figure, not one of twice it. It is IP65, so exposure is fine. One restriction to check first: the body is powder-coated aluminium and Havit excludes sites within 5km of salt water. All three carry a 3-year replacement warranty, and Lights For You can size a driver for an MR16 run if you tell us how many fittings share it.

Questions

Is 300 lm 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.

Which version can be dimmed?

HV1035T only, on a Triac dimmer. HV1037GU10T and HV1037MR16T are not dimmable with the globes supplied.

What size driver does the 12 V version need?

Size it for two lamps per fitting, then multiply by the number of fittings sharing it. It must be 12 V DC, within 25 m, with the supply inside 5% of nominal.

Can I aim the heads?

No. One is fixed up and one fixed down. If you want to aim them, the double adjustable Tivah is the version with 90 tilt and 270 swivel on each head.

What is the maximum globe wattage?

35 W per lamp on the 240 V GU10 versions and 20 W per lamp on the 12 V MR16 two globes at that ceiling, not one of double it.

Is it suitable for a coastal site?

No. This is powder-coated aluminium and Havit excludes installation within 5 km of salt water. The solid brass, solid copper and 316 stainless Tivahs are the coastal options.

Which beam angle suits a narrow pillar?

The 120 versions. Two wide fans overlap and wrap a narrow pillar; the 60 version suits a broad flat wall where you want two defined blades of light.
