Terrarium lighting fixture Exo Terra T5 Terrarium Top 39W 90 cm

Exo Terra T5 Terrarium Top 39W 90 cm is a lighting fixture designed to mount on top of reptile and amphibian enclosures. It accepts T5 fluorescent tubes and delivers 39 watts of power across a 90 cm length, providing uniform illumination suitable for daylight simulation, heat sources, and supplemental UV output when combined with appropriate lamps. The unit is intended for use in vivaria to support animal activity cycles and plant growth within terrariums.

Advantages

The fixture provides even light distribution across the full 90 cm length, reducing hot spots and shadows. Its compatibility with standard T5 fluorescent tubes gives flexibility in selecting daylight, plant, or UV lamp types. The low-profile design mounts on top of the enclosure for direct illumination and efficient use of space, while the 39 W rating offers a balance between output and energy consumption for many medium-sized terrariums.

Suitable for

• Medium-length reptile or amphibian terrariums up to approximately 90 cm
• Providing general daylight or plant-growth lighting when fitted with appropriate T5 tubes
• Supplementing heat and UV light sources when used with compatible lamps
• Display terrariums where uniform top-mounted illumination is required

When it may not be suitable

This fixture does not include lamps, so a separate purchase of compatible T5 tubes is required to provide light, heat, or UV. It is not a heat-emitting ceramic heater or a dedicated high-output HID/LED fixture; therefore, it may not be sufficient as the sole heat source for species that require intense basking temperatures. For very large enclosures or setups needing concentrated spot heating, additional or alternative heating solutions should be considered.

Key specifications

• Compatible lamp type: T5 fluorescent tubes
• Power consumption: 39 W
• Fixture length: 90 cm
• Mounting position: top-mounted on enclosure
• Intended use: terrariums for reptiles, amphibians, and plants

How to use

Install the Exo Terra T5 Terrarium Top on the top rim or lid area of the terrarium following the manufacturer’s mounting guidelines to ensure secure placement. Fit compatible T5 fluorescent tubes according to the lighting needs of the inhabitants—daylight-spectrum tubes for visual activity, plant-growth tubes for live plants, or UV lamps to provide ultraviolet radiation where required. Connect the fixture to a properly grounded power outlet and operate with a timer if consistent day/night cycles are desired. Ensure adequate clearance from animals and terrarium furnishings and avoid direct contact between tubes and moisture.

What to consider before purchase

• Verify the terrarium dimensions to ensure the 90 cm fixture fits the enclosure
• Plan which T5 tube types (daylight, plant, or UV) are needed and purchase them separately
• Assess heating needs of species; obtain additional heat sources if required
• Confirm electrical compatibility with local mains and grounded outlet availability

Usage recommendations

Use the fixture with a timer to maintain consistent photoperiods, select T5 tubes matched to the biological needs of plants and animals, and position additional basking heaters or heat lamps where higher localized temperatures are necessary. Regularly inspect tubes and the fixture for signs of wear, and replace fluorescent tubes according to the lamp manufacturer’s recommended service life to maintain effective light and UV output.
