Shim in this size is a surface-mounted step and wall light with a12W built-in LED behind an opal polycarbonate diffuser, in black or whitepowder-coated aluminium. At 9601,080lm it is an area light disguised as astep light: a run of these along a wall lights the ground properly rather than justmarking it. The opal diffuser matters at that output, spreading the light so the LEDs arenot visible as bright points from an approach. The listing sells all four combinations both colours in both voltages.

The choice to make: 240V or 12V

• HV3278T-BLK-240V / HV3278T-WHT-240V connect straight to mains.No driver or transformer needed.
• HV3278T-BLK-12V / HV3278T-WHT-12V require a 12V DC LED driver and mustnever be connected directly to 240V. On the 12V models thefitting is classIII, so no earth is required at the fitting itself.

All four give the same light: 960lm at 3000K, 1,020lm at 4000K and1,080lm at 5500K, tri-colour selectable at install. Choose on the circuit, not onoutput.

Where it works

• External stairs and landings where the treads need to be genuinely lit.
• Alfresco, pergola and patio walls under cover, as the main light for the area.
• Sheltered facade and courtyard runs, spaced as a repeating horizontal band.
• Commercial walkways and undercrofts where a tough aluminium wall fitting is specified.

Specifying it

IP54, so keep it to sheltered positions: eaves, soffits, pergolas andcovered walkways rather than walls taking driving rain. IK10, the highest impact class incommon use, which is why it stands up in trafficked commercial positions.Not dimmable in either voltage, so at over 1,000lm plan theswitching deliberately. On the 12V models keep each fitting within25m of its driver a warranty limit and size thedriver on 12W per fitting plus headroom. Rated to over 30,000hours. The LEDis built in: no globe is needed and none can be fitted. Must be installedby a licensed electrician.

Backed by a 3-year replacement warranty.

Questions

Does the 240V version need a driver?

No. The 240V models wire straight to mains. Only the12V models need a 12V DC LED driver, and those must never be connecteddirectly to 240V.

Is the output the same in both voltages?

Yes. All four SKUs give 960lm at 3000K, 1,020lm at4000K and 1,080lm at 5500K. The difference is only in how they are powered.

Can it be dimmed?

No. Neither voltage is dimmable. At this output that is worthplanning around switch it separately from any low-level marker circuit rather thanexpecting to turn it down.

How far can a 12V fitting be from its driver?

Up to 25m. Past that limit Havit’s warranty does not apply, andat 12W per fitting voltage drop over a long run shows up quickly.

Will IP54 cope on an outdoor wall?

In a sheltered position, yes under an eave or a pergola it iswell within rating. On a fully exposed wall or near surf, specify IP65 or better.

Does it take a globe?

No. The 12W LED is integrated and not user-replaceable, so thereis no globe to source and none to change.
