Luta 316 Stainless Steel TRI Colour

The Luta is an adjustable recessed inground uplighter with a 316 stainless steel cover on an aluminium body, and this listing sells the square part, HV1825T-SQ. It sits in a canister below ground level, finishing flush behind clear glass. ⚠ Havit rates it trafficable to 500 kg — foot traffic and a light vehicle, and materially less than the 1000 kg of Havit’s Klip and Toldo inground ranges, so check the load before you put it under a driveway a heavy vehicle will use.

It takes a replaceable MR16 globe — and that changes almost everything about it

⛔ Unlike most of Havit’s inground range, the Luta is not a built-in LED fitting. It has an MR16 lamp base and ships with a 5 W tri-colour MR16 globe fitted. That globe produces 270 lm at 3000K, 285 lm at 4000K and 300 lm at 5500K through a 120° beam at CRI >80 — so those figures describe the light as it is supplied, and the beam angle is set by whichever globe is in it, not by the fitting. Havit’s ceiling is 20 W MR16, and the fitting’s own lamp expectancy is >30,000hrs.

Setting the colour temperature means taking the globe out

⚠ The tri-colour selector is on the side of the globe, not on the fitting. Havit’s step 10 has you unscrew the 4 nuts, remove a C-clip and ease the globe out to reach it. It leaves the factory on 3000K, so ⛔ set the colour temperature before it goes into the ground. The head tilts up to 30°, so you can aim it at a wall or a tree.

Low voltage: a driver, parallel wiring, and a ±5% limit

This is a 12 V DC constant-voltage fitting, so it runs from a suitable 12 V DC LED driver. ⛔ It must not be connected directly to 240 V. It is Protection Class III — low voltage, no earthing required, which all three of Havit’s current documents state the same way. Fittings are wired in parallel, and the supply reaching each one has to stay within ±5% of the rated voltage or the warranty is void — volt drop on a long garden run is the usual reason that limit is missed.

The hole, the drainage, and the conditions that carry the warranty

Havit’s drawing gives the cutout with the canister as Ø104 mm — only the face shape differs. ⛔ Drainage below the canister is a warranty condition, not a suggestion: Havit asks for a 100 mm space beneath the canister and 100–150 mm of crushed rock below that, and states plainly that where no drainage is allowed the warranty will be voided. The canister must finish level with the ground — failure to do so voids the warranty in its own right. The anti-syphon plug and the male and female connector on the 300 mm tail must both stay on the cable; every o-ring and seal has to be seated, joins soldered and covered watertight, and silicone run around the edge. It is IP67 and IK10. ⚠ 316 stainless still needs regular cleaning to stop tea staining forming, and tea staining is not covered by the warranty — Havit’s HV9971 kit is made for that job. Havit’s HV9507 and HV9508 tri-colour MR16 globes are the listed replacements. Every figure on this Lights For You page came from Havit’s current HV1825T-SQ data sheet and its FEB24 install sheet, which state a 3 Years Replacement Warranty.
