Frequently Asked Questions

What is the difference between RGBW and RGB pool lights?

RGB pool lights mix red, green, and blue LEDs to create a range of colours, but the white produced by mixing all three channels is often warm or slightly tinted. RGBW lights add a dedicated white LED chip, producing a true, clean white light independently of the colour channels. This means you get both vibrant colour effects and a proper white light for night swimming — without compromise.

Is the SLX suitable for a new pool installation?

Yes — the Astral Pool SLX is designed for new pool installations. The 20-metre cable provides flexibility for the conduit run from the light niche to the equipment area. Ensure the niche and conduit are installed to suit the SLX specifications during the construction phase. Consult your pool builder or a licensed electrician for installation.

Can I replace an existing pool light with the SLX?

This depends on your existing niche size and type. The SLX is designed for new installations with a compatible niche. If you are looking to replace an existing light, check whether the SLX face ring and body dimensions match your current niche — or consider the Astral SLX replacement light (niche replacement version) instead. Contact us with your existing light details and we can advise the correct replacement.

Does the SLX require a transformer?

Yes — LED pool lights operate on low voltage (typically 12V) and require a suitable transformer. The transformer must be installed by a licensed electrician in accordance with Australian wiring rules and local council requirements. Ensure the transformer is rated for the cable length and light wattage. Contact us if you need advice on compatible transformers for the SLX.
