LX-BG84786 Underwater Light

A single-LED, mains-input submersible: the LX-BG84786 runs on AC220V with DALI control, which sets it apart from the low-voltage models in the underwater range.

Specifications

A different electrical concept

Every other underwater model in the range takes a low-voltage 24V feed; this one takes AC220V directly and is Class I, which changes the installation conversation: no remote low-voltage driver sits between the supply and the fitting, and the wiring design follows mains practice for submersible equipment in the destination market. Control is DALI only — there is no DMX512 variant — so the model suits buildings already running a DALI system, where the underwater fittings join the same control network as the interior lighting. A single CREE CXA1512 emitter behind the glass gives one clean beam rather than a multi-point array, in 15°, 25° or 45° beam angles.

Build and application

At 3.4 kg this is the heaviest underwater model in the range, in the same SUS#316 housing material with 10mm tempered glass and an IK10 impact rating. The colour span is white only, 2200K-6500K at Ra≥80; there is no RGBW variant, so colour scenes are out of scope for this model and belong with the LX-SC009 or the RGBW series models. Typical placements are architectural water features and pool installations on DALI-controlled projects where a mains-input fitting simplifies the electrical design.

When a mains-input submersible is the right answer

The low-voltage architecture used by the rest of the range exists for good reasons: drivers sit dry and accessible, and the wet side carries a safety-extra-low voltage. A project chooses the AC220V route when the electrical design already runs mains to the water feature — a retrofit basin with existing mains conduit, or a DALI-controlled building where each fitting is a network citizen in its own right. The decision belongs to the project's electrical engineer, and it interacts with the destination market's rules for submersible mains equipment; the input and the Class I construction are plain facts of the model, so the conversation starts from them rather than from an assumption.

DALI in a wet location

DALI control on a submersible fitting behaves exactly as it does on an interior one: the fitting is addressed, grouped and dimmed from the building system, and it reports back into the same management layer. For a hotel or civic project that already runs its interior lighting on DALI, the water feature stops being a separate control island with its own controller to programme and maintain. The limits are equally plain: DALI is a building-control protocol, not a show protocol, so fast sequenced colour work is out of scope even before the fitting's white-only colour range settles the question. Projects that want scenes should look at the DMX512 models; projects that want the water feature to behave like the rest of the building should look here.

Single-emitter optics

One CREE CXA1512 emitter behind a 10mm glass produces a single coherent beam, without the multi-point sparkle of an array fitting. On a still surface that reads as calm and deliberate; under a moving jet it gives a cleaner column with less visual noise. The three beam angles (15°, 25°, 45°) cover the narrow-to-medium range, so the model is aimed at defined targets — a jet, a fall, a feature wall under water — rather than at wide-area flooding of a big basin floor, which is array work.
