Uh hmmmm I am not familiar w/ the PowerSun UVB --- at all!!!! I just know this is what is recommended on the forum ---
Which
UVB light should I use?
The best
UVB light is a ReptiSun 10.0 fluorescent tube HO (Or Arcardia 12% in the UK). Compact or coil bulbs do not emit the proper amount of
UVB light for a bearded dragon, and should not be used. Other brands, such as the Zilla Desert Series and ReptiGlo have been known to cause eye problems and other health issues with bearded dragons, and should be avoided. The reason that some UVB lights (Zilla, ReptiGlo, coils/compacts, ect.) are considered dangerous is because the wavelength of UVB that they emit is shorter and more intense than the wavelength of the "safe" lights (ReptiSun, Arcadia).
UVB lights should be replaced every 6 months. The T5’s are a strong bulb and only need to be replaced once a year – the T 8 every 6 months--- where as the T 8 are not as strong—they need to be placed inside the tank the T 5 10.0 bulb approx 10-11 inches from basking spot – the T 8 approx 6-8 inches from basking spot—the cover needs to be off the bulb for full effect of the UVB rays--
Others on here can give you some advice on that Power Sun bulb---- it is a bulb correct ? that could be the reason for the different poop--- is he eating normal diet like leafy greens and bugs ? What else are you feeding him? His behavior is different from what I read -- that has a lot to do w/ the UVB--- like I said I am not familiar w/ the Power Sun --- I am hoping others on here can weigh in on this and give advice on it--- If its an ok UVB I wouldnt want you to go buy a whole new set up but if its not then I would recommend it and also if it is an ok UVB you probably do need to change it ---
