This is the largest Corba a recessed brick light at 10W, reaching 550lm. At that outputit stops being a marker and becomes a working light, which suits a driveway wall, a wide entry or a longflight of steps where the fitting is expected to put usable light on the ground.

Only the 240V model dims and that decides which one you buy

This is the single most important thing to get right on this listing, because the two voltages arenot equivalent here. The 240V codes are Triac dimmable;the 12V codes are not. If dimming matters and at 550lmbeside an entry it often does you must buy the 240V version. Ordering the 12V code and adimmer will not produce a dimmable installation, and the fitting is not at fault when it does not work.On the 240V version, pair it with a Triac (leading-edge) wall dimmer.

Confirm the cut-out before you cut

The smaller Corba models publish their apertures; for the 10W model the cut-out andinstallation depth are not published, and they are certainly larger than the 6W model’srather than the same. Do not scale them from the smaller sizes measure the fitting or the canisterin hand, and cut a test aperture, before any brickwork is cut or built. Getting this wrong on a recessedfitting is the one mistake that cannot be undone with a screwdriver.

Six order codes

Three finishes in two voltages. The 240V codes wire straight to mains and are the dimmable ones;the 12V codes need a 12V DC LED driver sized for the run at 10W each,four fittings already draw 40W. Black is the least expensive finish; antique brass and brass carrya premium and suit a cover plate that will be seen close up.

Specifying it

The 10W LED is built in no globe, no socket. Tri-colour switching gives 490lm at3000K, 550lm at 4000K and 510lm at 5500K; the middle setting isthe brightest, so treat the three as colours. IP54 covers rain and splashing, not jets. Aluminium,supplied with its cover.

Lights For You stocks the Corba in 3, 6 and 10W. If you want this output and dimming, order the240V code it is the only version that offers both.

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.

• HV3013T-BLK-240V, HV3013T-AB-240V, HV3013T-BR-240V 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.
• HV3013T-BLK-12V, HV3013T-AB-12V, HV3013T-BR-12V 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

Can this be dimmed?

Only the 240V codes, which are Triac dimmable. The 12V codes cannot be dimmed, so order the 240V version if dimming matters.

What size hole does it need?

The cut-out and depth are not published for the 10W model. Measure the fitting or canister in hand and cut a test aperture do not scale the figures from the smaller Corba sizes.

How does it compare to the 6W Corba?

Roughly twice the output again 490550lm against 260290lm in a larger body. It lights the ground rather than marking the wall.

What is the difference between the six order codes?

Three finishes black, antique brass, brass in two voltages. 240V wires straight to mains and dims; 12V needs a driver and does not.

How big a driver do the 12V codes need?

At 10W each, four fittings draw 40W. Size the driver above the total with headroom and site it to suit its own IP rating.

Which colour temperature is brightest?

4000K at 550lm, against 490lm at 3000K and 510lm at 5500K.

What is the warranty?

Three years, as a replacement warranty.
