No none of the coils are good --- you need a long tube fixture like what I posted
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 8-10 inches from basking spot—the cover needs to be off the bulb for full effect of the UVB rays--
The Arcadia Pro is a relatively new combo kit that Arcadia put out that includes a grow light style fixture along with one of their bulbs (6%, 12% or 14%). This has the hanging clips similar to the grow light fixture options. I haven't tested the output of this one yet, but it replaced the older combo set that LightYourReptiles sold which included a SunBlaze grow light fixture (these were excellent and I still use them). These are also available in the UK via Swell Reptiles.
