Results from new design of enclosures
UV-B levels inside vs. outside (measured simultaneously)
First, a recap on the problem. This is typically the situation under
The 'red' areas here show cutaneous fluids responding to the
infra-red and absorbing excess heat.
In extreme cases this can result in:
These are results (for comparison) obtained within the new housing
The heat is even distributed through the entire body, even reaching
the underside (plastron, on a tortoise):
This deeply penetrating, even heating effect is typical of sunlight
and WiRa compared to the infrared generated by normal basking lamps.
Some more examples..
vs. typical localised heating from 160w MV lamp. Note especially
extremities in 'shaded' side. Most of this heat is concentrated on
Again... basking lamp heat distribution....
In wild tortoises, heat is distributed extremely evenly. This can be
checked even with simple tools:
