How often should a reptiles UVB bulb be replaced?
The answer to this question is between 6 months to a year of usage.
Why ? Once it is switched on the UVB output of a reptile lamp diminsihes, so for example if you purchased a 10% UVB light at first switch on its UVB ouput would probably exceed this level as the manafacturers allow for this UVB fade and rate the tubes higher so that they can "burn in" to their expected output. However after 6 months this output may have dropped down to an output of 5% and by the time 12 months has passed the actual UVB being produced by the lamp will be either zero or minimal.
As we know UVB is essential for reptile health, so ideally you will replace your strip lights every six months if not they will definatly need replacing after a years use.
When we say 6 months to a years use this is meant as a typical 8 hour light period every day, if your lights are on longer each day then this of course will shorten their usefull life even more.
