Hi there, as mentioned above...
The light you posted in the picture is not a tube light, it looks to be a compact
UVB bulb. The sooner you can get your hands on a UVB tube the better, I'd turn off the compact for now, and not use the colored light. (If you have any household bulbs anywhere those work for basking lights, provided they output enough heat. You'll have to play around with those)
Moving forward I'd recommend a standalone basking light + UVB tube w/a reflector
You'd want something along the lines of

In terms of Reptisun UVB tubes, the 10.0's are the ones you want (as opposed to a 5.0).
There is the 10.0 T8 bulb, which is lower UVB output than its counterpart, the 10.0 High Output (HO) T5. The T5 and T8 will tell you which kind of fixture you need to use with it.
T8's are typically mounted inside the tank, under the screen for optimal UVB exposure while the T5's are normally too strong at an 'inside the tank' distance and are kept above the screen (Every situation is different, though).
I also see that you have a black light (for night time I'm assuming). This black light will also cause eye problems, and will disturb the sleep of your dragon at night. Since I don't see any other bulbs, do you have a basking lamp as well?
Tl;dr:
1) I would recommend getting a tube
UVB bulb as linked above, as well as a separate basking bulb (Can use a white non-colored household bulb, I wouldn't recommend colored bulbs)
2) I wouldn't recommend using a night light, if your temps drop below 65ish at night, get a Ceramic heat emitter (and make sure you're using a dome that can handle it)
