• Genuine Fluval part A20436 — matched output for the 32 W, 61-85 cm fixture size.
• Direct swap — connects at the same cable plug as the original driver.
• 240V AU input — supplied with an Australian plug, no adaptor needed.
• Shared across ranges — one driver fits both the Plant 3.0 and Marine 3.0 fixtures at this size, since both use the same power stage.

This driver fits the Fluval Plant 3.0 LED, 32 W, 61-85 cm and the Fluval Marine 3.0 LED, 32 W, 61-85 cm. It is sized specifically for the 32 W/61-85 cm fixture — the 46 W and 59 W Plant 3.0 fixtures use their own, higher-output drivers and this part will not run them correctly. Fluval has not published confirmation that this driver fits the newer Marine 4.0 range; if your fixture is a 4.0-generation unit, check the model plate or contact us before ordering rather than assuming compatibility from the title alone.

We could not confirm a supersession history (older or newer replacement part numbers) for this driver from Fluval's published material.

A fixture that won't power on at all, or that loses power intermittently, when the LED bar itself is otherwise undamaged. This is the power supply stage only — Fluval's own material does not specify whether the driver also carries the Bluetooth control board, so if your fault is specifically a Bluetooth pairing issue rather than a power issue, contact us before ordering.

Suitable as a like-for-like replacement for a failed original driver on the specific fixture sizes listed above. Not suitable as a universal or upgraded power supply for other Fluval LED ranges.

Fluval's own material doesn't detail fitting difficulty for this part. It connects via the existing cable plug between the light bar and the wall outlet, which is generally a straightforward plug swap rather than a job requiring the fixture to be opened — but check your unit before ordering if you're not confident it's the driver rather than the light bar itself at fault.

General Fluval warranty terms apply to manufacturing defects, in addition to your rights under Australian Consumer Law. Standard parcel freight.

How do I know if it's the driver and not the LED bar?

If the fixture is completely dark and unresponsive with no sign of any diode lighting at all, the driver is the more likely fault. If some diodes still light but look dim, uneven or wrong-coloured, the LED bar itself may be the issue instead.

Will this work on my Marine 4.0 light?

We can't confirm that from Fluval's published material — the 4.0 range appears to be a separate generation. Check your model plate or ask us before ordering if that's your fixture.

Does this include a new cable?

Yes — it's supplied as a complete unit with its Australian mains plug.

Can I use a higher-output driver on this fixture by mistake?

No — use the driver matched to your fixture's wattage. A mismatched driver risks under or over-powering the LED bar.
