Blue Pet T4 Submersible LED Aquarium Light

The Blue Pet T4 is a fully submersible LED light made for freshwater . It fits neatly inside the tank or sits above the waterline. Its glass body carries a bright, colour changing glow that brings out the natural shades of fish and plants. The Blue Pet T4 range comes in five sizes, so a fitting light is available whatever the length of your tank.

Key Features

• The light is fully submersible, so it works equally well underwater or mounted above the surface.
• A glass body with a glossy finish resists fogging and stays clear with normal use.
• A colour changing glow, including a blue and white mode, enhances fish colour and plant tone.
• The light includes two suction cups, for a firm hold against the glass on the side or the lid.
• Power draw stays low across the range, since even the largest model uses only a few watts.
• The Blue Pet T4 supports both freshwater and marine tanks, so one product line suits most home aquariums.

Technical Specifications

Every Blue Pet T4 model runs on standard 220 volt household power. Each one uses a glass tube body with an internal LED strip. The light length is the length of the tube itself. The suitable tank size shows the tank length the model suits best.

Choosing the Right Blue Pet T4 Size

Picking the right size mostly comes down to matching the light length to the tank.

• A tank between 20 and 30cm long suits the T4-20F, the smallest model in the range.
• A tank between 30 and 40cm pairs well with the T4-30F, a common choice for small community tanks.
• A tank between 40 and 50cm works best with the T4-40F, which balances brightness and coverage.
• The T4-50F and T4-60F serve larger tanks well, from 50 to 70cm, since both models add wider coverage.

When a tank falls between two sizes, the larger model is usually the safer pick, since it gives fuller, more even coverage.

How to Install the Blue Pet T4

Setup is simple and takes only a few minutes.

• Fix the two suction cups to the inside of the glass, either along the back wall or under the lid.
• Press the glass tube firmly against the cups until it sits securely in place.
• Route the power cable up and over the tank edge, away from any splash zone near the plug.
• Switch on the light and use the control, where fitted, to choose between the available colour modes.

Because the light is fully submersible, it can also rest directly underwater without the suction cups. It can sit along the substrate for a different lighting effect.

Benefits for Fish and Plants

Good lighting does more than brighten a tank. The Blue Pet T4 brings out the natural colour in fish scales and fins. This is especially noticeable with blue, silver and metallic species.

Care and Maintenance

A little regular care keeps the Blue Pet T4 working well for years.

• Wipe the glass tube gently with a soft cloth to clear algae film, since a clean surface gives a brighter, clearer light.
• Check the suction cups occasionally, as they can loosen over time in warm water.
• Unplug the light before removing it from the tank for cleaning, for safety.
• Store the light in a dry place during any extended period out of use.

Following these steps helps the Blue Pet T4 stay dependable across daily use.
