Retro Fit T5 LED – 4W 55cm DAY SUNNY

This LED retrofit tube is for aquarium keepers who want to replace an old T5 fluorescent tube in an existing hood or fixture without rebuilding the lighting unit. It is a 55 cm, 4 W module with its own power supply, so the old ballast and starter circuit are not used.

Why it matters

• Own power supply: the tube runs on a built-in driver with a switch on the 1.5 m cable, so the old ballast and starter can be removed from the fixture.
• Light along the full length: the manufacturer states that light is emitted across the whole tube, from end cap to end cap, rather than only along part of its length as in some retrofit designs.
• Glass housing: the LED assembly sits inside a glass tube, which the manufacturer describes as highly water resistant and clear, and which does not cloud over time as plastic tubes may.
• Lower power draw: the manufacturer gives energy savings of up to 75% compared with fluorescent tubes, and the tube draws 4 W.

What it works with

The tube fits T5 fixtures and uses included adapters for mounting in the existing sockets. The Day Sunny mix is intended for planted and reef-style setups, where the manufacturer states it supports plant photosynthesis and emphasises the colour of fish and plants. The series covers lengths for T5 tubes of 24 W, 39 W and 54 W, and this 55 cm model is one of them.
