LX-SC009 Underwater Light

The LX-SC009 is an IP68 stainless steel luminaire with CREE LED mixed-colour output, engineered for fountains, pools and water features.

Specifications

Three sizes, one colour system

The model is built in three size variants, marked A, B and C, carrying 3, 6 or 9 LED pieces and weighing 0.64 kg, 1.13 kg and 1.51 kg respectively, up to the 24W maximum. Mixed-colour output is the point of the design: a single fitting mixes its colour channels at the source, so a pool wall or fountain ring lit by several fittings shows an even colour field rather than alternating single-colour points. The colour range runs the full 2200K-6500K white span plus RGBW, at a CRI of Ra≥80 across the range.

Control and electrical notes

Control is by DMX512, DALI or 0-10V; unlike its LX-UD005 sibling there is no plain on-off variant, which fits a model aimed at colour scenes. The fitting is Class III on a DC24V supply at 350mA, 500mA or 700mA depending on variant, so the driver and the control signal both need specifying in the inquiry. The IK10 impact rating is the highest in the underwater range and suits pool walls and fountain basins exposed to cleaning tools and swimmers' feet.

Where it is used

Its applications are fountains, pools and water features. In a pool, the three size steps let a designer keep one fitting family along a wall while varying output with depth and spacing; in a fountain, the mixed-colour output carries the colour programme without a separate white fitting alongside.

Choosing between the A, B and C sizes

The three size variants are a scale ladder for one design language. The A size, at 0.64 kg with 3 LED pieces, is a detail fitting: step edges, small basins, the rim of a spa. The B size, at 1.13 kg with 6 pieces, is the general-purpose pool and fountain fitting most walls will carry. The C size, at 1.51 kg with 9 pieces, is the output end of the family, for larger water where fewer, stronger points read better than many weak ones. Because all three share the colour system and the control set, a scheme can mix sizes across a site — C fittings in the main basin, A fittings on the steps — and still run as one programme with one spare-parts logic.

Mixed colour, explained plainly

Mixed-colour output means the colour channels are combined inside the fitting, at the source, rather than by alternating single-colour fittings around a ring. The visible difference is at the water surface: a mixed source throws one colour that stays the same colour across the whole lit field, while alternating fittings throw a field that shifts hue as you move around it. For colour scenes that crossfade — the normal fountain and resort-pool programme — mixed output is what makes a slow fade look like a change of light rather than a change of fittings. The trade-off is discipline: the colour variant and the control variant are fixed at order, so the programme has to be imagined before the fittings are bought, not after they are installed.

Pool wall practice

On a pool wall, evenness is judged from the water surface at night, not from the fitting layout on paper. Space the fittings so their 20° or 30° beams overlap at the surface line, keep them at a consistent depth so the surface pattern repeats, and put the brightest part of the pattern where swimmers actually look — along the main axis of the pool. Where the pool has a beach entry or a step run, the smaller A size keeps the family resemblance without overpowering a shallow zone.
