Help with new beardie enclosure please

[MasterJiraya]

Was wondering if anyone had any options or advice on my beardie’s terrarium. We just got him and purchased Exo Terra’s 20g long beardie starter kit. Came with exo terras MVB solar glo bulb and hanging mount. I was told this was good as an all in one light but my wife and I have been considering changing it to something else for a more accurate heating light. I’ll post a pic as well so please give any advice you think would be best for our beardie. Thank you in adance!

I think you'll find the 20L is not going to be big enough for very long, so you may want to consider a tank upgrade at the same time, if you can manage it, so you can get the different fixtures for the bigger tank, instead of for the small one now and then new ones later when you have to get the bigger tank.
Most often-recommended UVB seems to be reptisun t5HO or T8 (depending on how it will be placed) with 10.0 tube bulb, with the fixture about 2/3 the length of the tank, or Arcadia 12% or 14% (I think) same idea. Basking bulbs have lots of options, including household halogen floods (PAR20, PAR30, PAR38, some BR ones, I think, but I don't know sizes), again depending on how they're placed. CHE or heat projector for supplemental non-light-emitting heat if needed. But I would definitely look into tank options first. 40gal breeder is the smallest you'd want once your beardie is grown, and if you can do a 48"x24"x24" like a zen habitat (there are other makers, too), that's even better, and there's no harm in putting the little guy in a big enclosure - just make sure he can easily see and get to his food, and nothing's too high up at the start - they like to jump off things, and have no depth perception, apparently.
