What makes the Arcadia D3+ stand out
Arcadia is a specialist brand in reptile lighting, and the D3+ line is formulated specifically for animals that depend on UV-B for vitamin D3 synthesis. Unlike generic fluorescent tubes, this lamp combines a precise UV-B percentage with a daylight colour temperature that encourages natural basking and activity patterns.
Ideal for...
Reptile keepers maintaining terrestrial or semi-aquatic terrariums for species such as bearded dragons, tortoises, and diurnal lizards that require a reliable UV-B source. Also suited for keepers upgrading from T8 to T5 fluorescent systems for improved UV output efficiency.
Application of the Arcadia D3+ Reptile T5 Lamp
Install the lamp in a compatible T5 ballast fixture mounted inside or above the terrarium
Ensure the lamp is positioned within the recommended distance from the basking area (refer to Arcadia installation guidelines)
Replace the tube every 12 months to maintain consistent UV-B output, as UV emission degrades over time even if the lamp still appears to light
Always switch off the lamp during nighttime hours to maintain a proper day-night cycle for the animal
