This is the big one. At 24 W and around two thousand lumens, the largest Oasis is notan accent light it is the fitting you use when something genuinely large has to be lit. A mature gum,a two-storey render wall, a stand of palms, the full width of a driveway. For scale: it produces roughlytwice the light of the 12 W Oasis and more than twenty times a small 1.5 W accent spike. Used on a shrubit would be absurd. Used on a tree that actually needs it, nothing smaller in the range will do the job.

Twenty-four watts at twelve volts is a real design constraint

Power is the thing to plan around, and it catches people out. Twenty-four watts at 12 V DC meansroughly two amps per fitting so three of these need a driver rated well past 72 W, andthe cable has to carry that current without the voltage sagging. Havit sets the limit as a warrantycondition, not as advice: the fitting must sit no more than 25 m from its driver and thesupply must stay within 5%. Its installation sheet is equally direct about the otherhalf: “Use an appropriate 12v DC LED Driver DO NOT CONNECT LIGHT FITTING DIRECT TO 240V.” On arun of these, size the driver and the cable together before anything is trenched.

Where it should not go

The body is aluminium, and Havit’s installation sheet draws a hard line:“Aluminium and 304SS fittings must not be installed within 5km of any salt water environments.”That is a warranty boundary, not a suggestion. If your garden is inside that distance, the polycarbonateand solid brass fittings in the range exist for exactly this reason. Elsewhere the aluminium body,IP65 sealing and 260 mm spike are entirely at home in a bed, a lawn edge or agravel run.

Setting it up

• Tri-colour selectable 1900 lm at 3000K, 1970 lm at 4000K, 2040 lm at 5500K.
• The colour switch is inside. Twist the cover off anti-clockwise and the selectorsits on the side just below the reflector. Set it before the fitting goes in the ground; nobody enjoysdoing it afterwards in a wet bed.
• 90 tilt, a 260 mm spike and a 1 m reinforced cable.
• Built-in LED, so there is no globe to source or replace, and CRI above 80.
• A matching hood accessory is available for the 24 W worth it wherever the fittingsits below a sightline, because at this output the source itself is uncomfortable to look at.

Aluminium in poly powder-coated black, parallel wiring, and a 3-year replacementwarranty. As with everything on a buried low-voltage run, the wiring is licensed electrician’swork.

Before ordering more than one, send Lights For You the fitting count and the run length at 24 W eachthis is the fitting most often let down by a driver bought to suit the light rather than the load.

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.

Questions

How much bigger is this than the 12 W Oasis?

About double the light roughly 1900 to 2040 lumens against the 12 W’s 960 to 1080. It is the right choice for a mature tree, a tall wall or a wide driveway, and the wrong choice for a shrub or a bed edge, where it will simply look overdone.

What size driver does it need?

More than people expect. Twenty-four watts at 12 V is about two amps per fitting, so a driver has to be rated for the total load with headroom, and the cable sized so the voltage does not sag along the run. Havit requires the fitting to be within 25 m of the driver and the supply within 5%, both as warranty conditions.

Can I use it near the beach?

No. Havit’s installation sheet states that aluminium and 304 stainless fittings must not be installed within 5 km of salt water environments. Inside that distance, choose a polycarbonate or solid brass fitting instead it is a warranty boundary rather than a recommendation.

How do I change the colour temperature?

Twist the cover off anti-clockwise and the selector switch is on the side just below the reflector. Set it before the fitting goes into the ground reaching it later means opening a sealed fitting in a garden bed, and the seals have to go back correctly.

Is there a globe to replace?

No. The LED is built in, so there is nothing to source, no socket to match and no globe wattage to keep track of. The trade is that when the LED eventually reaches end of life the whole fitting is replaced rather than a globe.

Do I need the hood?

Only if the fitting sits below a sightline a path, a window, a seating area. At this output the source is genuinely uncomfortable to look at directly, and the matching 24 W hood shields it without changing where the light lands. Aimed away from people it is unnecessary.

Can several run off one driver?

Yes, but the arithmetic matters more here than anywhere else in the range. Total wattage, cable size and run length decide it together, and a driver at its limit shows up as dim or unstable output. Give us the layout and we will size it properly.
