Shim is the largest and brightest fitting in this range by a widemargin: a surface-mounted rectangle, 301mm long 65mm 120mm, with a 14W built-in LED behind an opal polycarbonate diffuser puttingout over 1,100lm at a 120 spread. It is not a step marker in the usual sense a run of these lights a wall and the space in front of it. The opal diffuser iswhat makes that bearable at close range: it spreads the output instead of letting you seethe LEDs. Available in black or white, in two voltages.

The choice to make: 240V or 12V

• HV3279T-BLK-240V / HV3279T-WHT-240V wire straight to mains.No driver or transformer required. At 14W this is usually theeasier specification.
• HV3279T-BLK-12V / HV3279T-WHT-12V require a 12V DC LED driver and mustnever be connected directly to 240V. A 14W fitting is aserious load on a low-voltage circuit, so the driver must be sized on the real total.

Output is the same either way: 1,120lm at 3000K, 1,150lm at 4000K and1,190lm at 5500K, tri-colour selectable at install, CRI above 80. Only the wiringdiffers.

Where it works

• Wide external stairs and landings at 301mm one fitting covers ground a small marker cannot.
• Alfresco and courtyard walls under cover, as the primary light for the area.
• Driveway and boundary walls in sheltered positions, spaced as a repeating band.
• Commercial entries and undercroft carparks where a robust wall band is wanted.

Specifying it

IP54, so Shim belongs in sheltered positions under an eave, apergola or a soffit and not on a wall taking driving rain or coastal wash. Wiredin parallel. Not dimmable in either voltage, which is worth weighing atthis output: 1,100lm on a patio wall is a lot of light with no way to pull it back,so consider switching it separately from any lower-level circuit. On the 12V models,keep each fitting within 25m of its driver, a warranty limit.Powder-coated aluminium in black or white; the LED is built in, so noglobe is needed and none can be fitted. Licensed electrician only.

Backed by a 3-year replacement warranty.

Supplied by Lights For You Shim is the 14W end of the step-light range and cannot be dimmed, so talk to us about switching and spacing before committing a full wall to it.

Coastal siting Havits condition

Havits installation instructions for this fitting state that aluminium and 304 stainless steel fittings must not be installed within 5 km of any salt water environment. That is a condition on where the fitting may go, and it sits beside the IP rating rather than inside it: a fitting can be rated for direct rain and still fall outside this rule, because the issue is salt carried in the air rather than water landing on the surface. If your site is inside that zone, talk to us before you specify it Lights For You can point you at a fitting whose material Havit does not name here.

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.

• HV3279T-BLK-240V, HV3279T-WHT-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.
• HV3279T-BLK-12V, HV3279T-WHT-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

Which voltage should I choose?

At 14W per fitting, the 240V version is usually simpler it wires straight to mains with no driver. The 12V version makes sense onlywhere a low-voltage circuit already exists and the driver can carry the load.

Does the 12V version really need a driver?

Yes, a 12V DC LED driver sized for the whole circuit, and itmust never be connected directly to 240V. At 14W each, only a few of these fiton a driver that would run a dozen 1W markers.

Can Shim be dimmed?

No, in neither voltage. Given the output, plan the switchingaccordingly a separate switch from your low-level circuit is often the practicalanswer.

Is IP54 enough for an outdoor wall?

Under cover, yes IP54 handles splashing and wind-blown sprayon a sheltered wall. On a fully exposed or coastal wall, choose an IP65 fittinginstead.

How far apart should they be spaced?

Further than you would space a small marker each fitting is301mm long and puts out over 1,100lm. Set the positions out on the wall andkeep the gaps even, because at this output uneven spacing is obvious after dark.

Is there a globe?

No. The 14W LED is built in and not user-replaceable, so thereis nothing to buy separately.
