You’ll want to replace the Zilla T8 UVB tube ASAP. House brands (Zilla’s is Petco’s and All Living Things is Petsmart’s) provide ineffective levels of UV (and some Solarmeter tests reveal that virtually no UV is emitted from some of the models). You need a Reptisun T5 10.0 HO UV tube at least half the length of the cage (which, hopefully, is very large. A 40 gallon breeder is considered the bare minimum, but a 4x2x2 gives them a much more ideal amount of space). You’ll want a fixture with a reflector for the T5 tube. You can use the Sunblaster fixture available on Amazon or you buy a fixture with a reflector specifically designed for Reptisuns. Reptisun T5s are proven to emit a desirable level of UV light, while many of the other brands are made in China, have caused vision issues for numerous species, and do not emit adequate UV light. The other proven UV tube is the Arcadia D3+12%, which can be a bit harder to find in the U.S., but it’s another option. A Reptisun T8 can work if it’s within 6” of the basking surface and not obstructed by a screen, whereas the T5 is strong enough to have a mesh cage top beneath it and still emit adequate UV. T8s also need to be replaced every 6 months, whereas T5s need to be replaced just once a year. It’s so important that you address the UV issue immediately. Temperature and UV lighting are the two most crucial elements that will make or break a dragon’s health. Your basking temperature is in the desired range for babies (between 100-110 degrees and no hotter). I’m assuming the basking surface temperature is being taken with a temp gun and that you’re not relying on a stick-on thermometer on the wall of his cage to presume the surface of his basking area is the same temperature of the wall of his cage. If not, get a temp gun pronto (I like the Zoomed digital temp gun available on Amazon and in pet stores). If you’re not taking temperatures using this method his basking surface temperature may be much hotter or colder than 108.5. As for tinted basking bulbs, reptile vision is different than our own, and colored bulbs can warp how they see their environment. Halogen flood bulbs (available at the hardware store) are great because they’re very heat efficient and bright (with no tint). Because they’re so powerful a lower wattage is usually required (vs a standard basking bulb). I currently have a 45 watt halogen floodlight in a 4x2x2 enclosure and it easily gets the basking area to the 95-105 gradient adults need. So if you go this route be very sure you have a temp gun and can monitor temperatures carefully. You may have to experiment with wattages. Someone once recommended a 75 watt halogen to me but it produced temps way too hot to be safe. So always check the temps with new lights before allowing the beardie back in the cage. Once you figure out the ideal wattage, floodbulbs are great because the bulbs are very wide and therefore create a wider hot spot than a narrower more concentrated basking bulb. Whatever route you go, it’s best to stick with bulbs that don’t have colored tints or coatings (including those awful red nightlights).
