One with wide angle kit or two regular X30's for a 36Lx18Dx19T reef tank

[Tbonphil]

Hey fellow reefers who have expertise with this. I am upgrading from my 29gal bow front (24Lx12Dx24L) tank to the 50 gal in subject line. I was able to exchange my Hydra for two x30 radions at the LFS since I am and have bought so much from them already. All I can say is WOW how much better the one radion is on my current 29gal!!!!! An incredible upgrade. Yea I know; it was $250 more, but wow, my corals (sps, lps and softies) are going crazy with the basic radiant set up ecotech has. so here's the question as I am getting different opinions; some say one radoin by itself at 13" high is enough, others say need two and some say only one with wide angle lens kit.

Do any of you have expertise or experience to help with this decision while I have the LFS on the dealing phase with all.

The Radion at Full Power is close to a 250 watt MH and covers 18-24"
