Ok, I am confused. There are so many UVB bulbs.
I know there are alot of posts on this from the type down to UVB.
I am buying the Exo-Terra Glow light and was looking at

Is this really nessacery or would a $12 Zoo Med 5.0 do just fine?
And, what is the deal with the daylight blue and the midnight red bulbs?
