## Description

These 7% UVB T5 bulb helps with the synthesis of Vitamin D3, and provides a targeted flood of UV from this full spectrum bulb. This provides 7% UVB along with a lower 17% UVA, which has been designed specifically with crepuscular species in mind.Crepuscular species tend to hide away during the day, and prefer dawn and dusk for investigating, so this lower light means its a more natural lighting for them, whilst still providing the very best in quality UVB. This is ideal for Leopard Geckos, Crested Geckos and many snake species, such as Corns, Kings, Milks and Rat Snakes, especially those kept in the "light and shade" method.This bulb is designed to be used in the ProT5 or MiniT5 ShadeDweller Kits, though could be used in an existing T5 8w Controller or the Arcadia 8w UV MiniKit.

Review: Great. Perfect replacement. - Arrived as described. Perfect replacement. In perfect condition. For future, my only concern would potentially be the packaging. Arrived in a flat box with no give and had the postman tried shoving it through the letter box (as they tend to do), it could easily have snapped the lamp.
Review: Fantastic - Fantastic

## Questions & Answers

**Q: My bulb has only lasted 4 weeks, is this normal?**
A: No, definitely not. Mine is still working after nearly a year although I swapped it out after 7 months due to the UVB getting weaker over time. Check if it's set up correctly, if it's not connected properly it might blow the bulb. I had it turned too far to one side at the beginning and it started flickering.

**Q: Is this suitable for bearded dragons**
A: No it is not, it is for nocturnal animals.

**Q: Is this the 12’ bulb**
A: Yes :)

**Q: What mm length is this?**
A: 290mm
