Kessil a150w on a 5 gal

[Bryan_k47]

I've read a ton on these last night
Alot of people run them on 10/24/20/29 gal tanks
I read about people running them on higher gallon tanks but shallow ones
Wouldn't a 12 inch deep tank be the same under this light wether its 10 inches long or 30 inches long? Either way it's still under the same intensity is it not ?
Wouldn't the deciding factor be tank depth versus gallons ?
