Cresties unlike other reptiles do not need the additional support
of a UV emitting Heat Lamp. Those other lizards need the Heat lamp as a
basking source as they warm up their entire body using it; but also require the UV radiation
from it in order to synthesise enough levels of Vitamin D3 to enable them to function
The Crestie does not need this requirement - but I
tend to use a light in the Terrarium hood during the winter months to give them a better
representation of daylight and night-time, mimicking their natural habitat. It must be said
though it's probably more for my benefit than theirs!
Lighting = additional
with the side effect of additional heating - bear this in mind as your geckos will gravitate
towards the light-bulb at the top as they seek out the heat- so ensure it is not too hot and
not touching the top of the Terrarium mesh or your geckos can and will get burned and severely
dehydrated - again the exo terra hoods provide a safe way of putting lights above the Terrarium
and you would then only need to watch the heat levels and choose a suitable wattage bulb to
control the heat.
