This is the round Lisca in white the same fitting as the square version with a circular face, andthe finish to choose on rendered, painted or light stonework where a black body reads as a dark spot byday. At this price it is the fitting people buy in sixes, which is exactly what a flight of steps wants.

Round or square, and why it matters

The two shapes are electrically identical and cost the same, so the decision is the wall. A round facesuits render, textured masonry and anything without a strong horizontal line, because it has nothing toalign to and therefore never looks misaligned. The square version sits better with brick or blockcoursing. On a single property, pick one shape per flight mixing them on one stair reads as asubstitution rather than a decision. Where a run crosses both kinds of surface, it is usually better tocarry one shape all the way through than to change halfway, because the eye follows the line of fittingsand notices the break long before it notices the wall behind them.

Two order codes, and only one needs a driver

• HV3227T-WHT-240V wires straight to mains. No driver.
• HV3227T-WHT-12V is 12V DC and requires a 12V DC LED driver.

Both cost the same, so the decision is about the circuit. One or two fittings off an existing pointare simpler at 240V; a run of six or more is usually better at 12V, fed from a single driver.The sheet lists the 12V model as Protection Class 3 (low voltage) and the240V model as Protection Class 2 neither needs an earth at the fitting.

Specifying it

The 3W LED is built in no globe and no socket. Tri-colour switching across 3000K,4000K and 5500K gives 150lm, 160lm and 155lm, set once at installation andnot adjustable afterwards. It is not dimmable. IP65 covers direct rain and hosewash-down and IK08 gives it real impact tolerance, which matters at shin height. The diffuser is clearPerspex, so the light has a harder edge than the frosted and opal fittings in this range. The cover isaluminium on a plastic mounting base the base takes the fixings and is not metal.

Available from Lights For You in round and square, black and white. Buy the whole flight togetherrather than one at a time: tri-colour LEDs from different production batches can vary very slightly intint, and on a row that is visible where a single replacement never would be.

Questions

What is the difference between the two order codes?

One is 240V AC and wires straight to mains; the other is 12V DC and needs a 12V DC LED driver. Both are white and both cost the same.

Round or square which should I choose?

They are electrically identical. Round suits render and textured masonry, where there is no line to align to; square sits better with brick or block coursing.

Does either version need an earth?

No. The 12V model is Protection Class 3 and the 240V model is Protection Class 2 no earth at the fitting either way.

Can it be dimmed?

No. This fitting is not dimmable in either voltage.

Is it all metal?

The cover is aluminium; the mounting base is plastic. The base is the part that takes the fixings.

Is it suitable beside a pool?

Yes. IP65 covers direct rain and hose wash-down, and IK08 gives it good impact tolerance at ankle height.

What is the warranty?

Three years, as a replacement warranty.
