Why do zoas grow like wild fire under MHs?

I have an AI Prime LEDs with 180 PAR near the top of the rocks. My zoas grow but slowly. Back when I had MHs they grew like 3x as fast. I've heard other's say zoas grew fast under MHs. Why?

It's not just Zoanthids. This is a debate that has been had countless times on every forum, from my experience it's:

 

Metal Halides

T5's

LED's

 

The trade off is efficiency, with LED's being the most cost effective, least amount of heat output, and longest life. I ran metal halides once, and the heat vs. growth wasn't worth it in my small space. Here are some of the discussions I found on WAMAS with a quick google search on Metal Halides Vs. LED's. 

 

Radions VS. Metal Halides

LED VS. Metal Halides

Geismann VS. Hamilton VS. LEDS
