Let me start by welcoming you to the wonderful world of bearded dragons, a magical land of mystery, enchantment, cuddles, love and, worry! A mysterious realm where things always seem to change in an instant and, the moment you think you have it all figured out, the rules change! You think you own your dragon? Ha Ha....guess again..... Like it or not, you are now a slave, lol!!!
A 150 gallon tank is a great space to have. You have room for lots of climbing branches which your dragon needs. You can also get great temperature gradients across the viv with two lights (4' Reptisun 10.0 t5 HO and, a 100watt basking bulb). Temperatures should range from 105° in an elevated basking spot, 95° on the warm end to 78° on the cool end. No colored lights are needed because they distort their vision. The CHE should only be used if temperatures in your house drop below 65° at night. No lights at night, they like it cool and, totally dark at night. Dark and cool allows them to slow their metabolism enough to actually rest when they sleep.
All those lights are not needed, that is the first thing that popped out to me.
