Tivah Black TRI Colour Double

Two independently aimable heads on one metre-long stem — and one restriction to check before you buy. This is the aluminium body, and Havit's installation sheet states that aluminium fittings must not be installed within 2 km of any salt water environment. Within that distance, choose the 316 stainless or solid brass Tivah instead. Beyond it, aluminium is the sensible pick: it is the least expensive twin-head in the family, and powder-coated black it vanishes into planting by day.

The number that catches people specifying a run

Each head carries its own 5 W MR16, so this fitting draws 10 W, not 5 W. Havit's own specification records the lamp wattage for this model as 2 x 5 w and the output as 2 x 270 lm at 3000K, 2 x 285 lm at 4000K and 2 x 300 lm at 5500K — 540, 570 or 600 lm across the fitting. Six of them is a 60 W load, not 30 W, and a driver sized on the single-head figure will be short. The heads are wired in parallel, so one globe failing leaves the other lit.

Why two heads rather than two fittings

Each head tilts through 90° and swivels through 270° on its own, so a single fitting can wash a driveway one way and a garden bed the other from one hole in the ground and one cable. Along a path it lights both directions instead of alternating singles down the run. The 1000 mm stem stands the heads near knee height once set — buried or sleeved to suit, and worth deciding before the cable run is closed, since the lead exits the base.

Globes, colour and supply

• Both globes are tri-colour and each is set at the globe itself: cover off anti-clockwise, glass out, switch on the side. Preset to 3000K. Set both the same unless you genuinely want two colours from one fitting.
• The beam belongs to the globes, not the housing. The supplied MR16s are 120° floods; narrower MR16s make the same fitting a pair of spots. Each socket is rated to 20 W.
• 12 V DC from a suitable 12 V DC LED driver. Do not connect the fitting directly to 240 V.
• No more than 25 m from the driver, supply within ±5% of 12 V — both are warranty conditions, and both bite sooner on a run of 10 W fittings than people expect.
• Not dimmable with the globes supplied. 2 m of reinforced cable, joints soldered and sealed. Never force a head past its stop; the internal cable twists and shorts, and that damage is excluded.

IP65, CRI above 80, and a 3-year replacement warranty.

Earthing and protection class

This fitting runs on 12 V DC and is Protection Class 3 — no earth is required at the fitting. The isolation comes from the LED driver rather than from an earth conductor, and the fitting must never be connected directly to 240 V.
