Light Bulb Help!

It is a 150-high dimensions 48" L x 24" D x 30" H. The Oscar is 12 inches, does that give more perspective?
 
I bought a ZooMed 36watt 48" 50/50 bulb from LFS recommendation and it is perfect. 50% daylight and 50% actinic. The lighting dimmed a little like I was hoping and now the colors in our Oscar and 3 Jewels pop out!
