150w DE Bulb Suggestions PLEASE

[Whatigot]

Howdy folks, I just want to start this thread by saying that I tried to read through the MH info on this forum, like Snajays spectral analysis and it may as well have been written in Japanese (which I don't speak)

I'm not trying to take advantage of all your hard reading and research, I'm just a little slow eh and could use some of your concentrated brain power to help me out.

I have a coralife M81 ballast that is controlling 2 150w DE 20k coralife bulbs that I am replacing soon.
The fixture itself is a coralife aqualight advanced which I think is a couple years old though it's very clean and looks new.

I was hoping that someone here could help me in choosing my next set of 150w de bulbs for this ballast and fixture setup.
I'm not as worried about aesthetics (blueness) as I am about being able to grow most sps, lps and so forth.
The tank is a 72 gallonbowfront, 4 feet long by 22 inches high with about 4 inches of substrate....

any suggestions wuld be appreciated and if any more info is needed about my setup to aid in giving me advice please post....

thank you very kindly.
