I've recently got two new Hermann tortoise and was just wondering how to measure the temperature of the basking lamp. Having the thermometer at ground level I get readings from 32-33 but I have been reading articles about it being read at tortoise shell height? I have a megaray 100W light and if I raise the thermometer in the air its only around 25-26? Am I doing something wrong? 

 

Many thanks,

 

Charles

The basking temp you need is at ground level. The tortoise will move to the correct area to attain the optimum core temperature. Megarays are good bulbs. As you have found the air temp is completely different, so stick to ground temps ;)

Thank you very much...I'll make sure that the ground temperature is roughly 32ish then :)

If you are looking for a temperature spot you look at the ground temp created by that spot. The temperature of the top of a tortoises shell will be roughly the same as the ground temp at that point, when it can move in and out of the hot spot to suit its own requirements. Air temps at the same level will be different, not being a solid object ;) The tortoises shell will take on a very different temperature to the air around it via thermoregulation, this is why you can pick up a tortoise on a cold sunny day and feel that it is warm, unlike our own bodies which would be cold under the same conditions and why keeping a tortoise in a hot room with no lamps, is not as good as a cooler room with heat lamps.
