The replacement ballast for an Aqua Zonic EVO Slim Natural LED light unit.
If the fitting has gone dead and the LED bar itself shows no damage, this is the usual cause. LED emitters outlast their power supplies by a wide margin, so on a fitting of this age the ballast is the part to suspect first.

- 45cm
- 60cm
Match it to the length of your light unit. The 30cm and 45cm units share the AL536/AL537 ballast and the 60cm uses AL537 — check the code printed on the one you are replacing rather than going by the fitting length alone.
Before you replace it
Check the plug and the connector at the fitting end. A loose barrel connector gives exactly the same symptom and costs nothing to rule out.
