I have two pythons in there plus on an upside we actually recently got the QLD climate change mob to come to our house and install the electicity meter etc etc and I was able to work out exactly how much that bulb uses an hour. If I were to have it on for 10 hours a day it would cost me -
.03kw per hour..which would be .3kw per day and we pay 22c per kw so approx 9c per day. etc etc but am only using the bulb for 2-3hours a day so reduces the cost greatly. I chose this bulb due to the tank size, a 60watt bulb (I realised you said as a guide) would not do anything for a tank this size, also right near the bulb is the top vent allowing air exchange-the heat from a 60 would go straight out this section.
I do have a 60watt upstairs in my Bredli tank. That tank is approx 120-140cm long. The ceremic bulb heats a very tiny section. I also see him on top of his hide positioned right below the bulb
I found that this bulb heats the top section of the wall-see photo's attached to a comfortable ttemperature...but I mainly got this bulb for heating the whole enclosure not a particular area-which I have found that when you open the tank and stick your hands in there you can feel a temperature difference in comparison to outside the tank...
I agree with the tolerence also, and have ensured that there are locations where the snakes are able to go to escape the heat.
WHOLLY -9 degree's...thats freezing haha how was the snake coping? Huddled up on the heatmat?
However thanks for the input.
