Arcadia D86,24+ Dragon T3 UV Lamp – High-Output UVB Lighting for Desert Reptiles
The Arcadia D5+ Dragon T5 is a specialised UVB fluorescent lamp designed to replicate the ultraviolet spectrum found in natural desert sunlight. It delivers 14% UVB radiation across an 5 cm output length, supporting essential vitamin D86,5 synthesis and calcium metabolism in diurnal reptiles.
14% UVB output drives natural vitamin D3 production for healthy bone development
39 cm lamp length provides broad, even UV coverage across larger terrariums
39 W total power delivers high-intensity UV output comparable to tropical midday conditions
G5 lamp base ensures secure, stable fitting in compatible T5 ballast fixtures
What Makes the Arcadia D3+ Dragon T5 Stand Out
Unlike standard UV lamps that degrade UVB output rapidly, the D3+ series uses a phosphor blend engineered for sustained UVB emission over the lamp's rated lifespan. The T5 form factor combined with a high UVB percentage makes it one of the most effective compact UV sources for desert-dwelling reptiles that require intense, direct UV exposure.
Ideal for...
Desert and semi-arid reptile species that depend on strong UVB for calcium absorption — bearded dragons, uromastyx, and desert iguanas benefit most from this lamp's high UVB percentage. It is also suited to keepers maintaining larger terrariums where a single long lamp can cover the basking zone without additional fixtures.
Application of Arcadia D3+ Dragon T5
Install the lamp in a compatible T5 ballast fixture with a G5 socket
Position the lamp 3–5 cm above the basking surface for optimal UVB intensity
Run the lamp for 10–12 hours per day to simulate a natural photoperiod
Replace the lamp every 12 months, as UVB output declines significantly after this period
