We’ve been using T8 fluorescent UVB tubes in are vivariums for several years now, they’re the ones that are 1″ (2.5cm) in diameter. No problem, they have served us well. But now Arcadia have brought out a range of T5 (5/8″) reptile UVB tubes.
I can remember when T5 bulbs were introduced to the marine aquarium hobby, they soon took over T8 bulbs due to their superior output.
Here’s what Arcadia say about their T5 Reptile Lamps;
“The new T5 lamps are available in both D3 Forest Species (6% UVB) and D3+ Desert Species (12% UVB) versions.
The D3 lamp is three times as bright as the equivalent T8 D3 lamp, with 80% more UVB, while the D3+ is twice as bright as the equivalent T8 D3+ lamp and has 95% more UVB. Without a reflector, these lamps give 31ÂµW/cm2 and 61ÂµW/cm2 UVB at 30cm respectively and both have a UVA concentration of 30%.”
There are 3 sizes of both the D3 and the D3+ tubes available. Specialist T5 starter units and tube reflectors are also now available.
