yeah im saying if u have a heatlamp/uvb all in 1 u don't use D3 but if u have them separate u use D3 and i use the reptisun uvb light its the best one imo

you should check out beardeddragon.org its where i learned alot about my gizmo when i first got him

It sounded like a question to me.

But your statement is still not right. If you have a strong enough source of UVB, and it is not old, and it is at the right distance, you do NOT need to suppliment with D3. In fact, if you do provide UVB + suppliment with D3, you are risking calcium overdose which can be deadly.

UVB is the same, whether from the sun, UVB tube, or MVB bulb. Depending on what bulb you have specifically, it will vary on how much UVB is pumped out. There are many variables - bulb type, bulb strengh, bulb design (focuses the UVB to a tiny basking spot, or a wider area), distance to basking spot, how much time the animal spends in the light, etc etc.

But if your beardie is getting sufficient UVB (no matter the specific source), you won't to be very careful using D3.
