I know you're looking for equipment and prices, but I just want to offer a little advice through my opinions. As lighting is absolutely not a cut and dry subject in the reefing community.
It really depends on what corals you want to grow.
I started out with a 55g that came with a led bar like yours, just not as nice as yours. It was decent. But not to grow really anything well except cyano. But that was just in my case.
Only a year in, I didn't want to invest too much. So I found a used cheap t5 fixture, $50. It was a Coral life in my case. That light was a huge difference. Then I bought new bulbs for 100 bucks. Ran them for about another 18mo. Thats when I decided I want to do this long term. So I invested in some quality leds. But those were crazy expensive. Especially how frugal I am. Ok.. I'm friggin cheap, fine.
The china made leds (black box) have really stepped up their game and there's a lot of reefers out there using them, regardless of price. I've never run them myself, but I did visit a local reefer that only uses them and his tanks looked amazing. I plan to try them sometime.
So:
t5 lights will grow Anything and are pretty much plug and play.
Leds are a bit finicky but are great if you're into wanting to adjust and play with your equipment. The cost is higher.
If I could do it over. I would buy 2 black boxes and a Seneye reef monitor to measure my lights intensity. That would be an investment of about $400.

But you can't beat the used t5 fixtures that sell all the time for 50-100 bucks, fitted with 4 new ATI, Giesemann or something equal in quality. Then you're set for 12-18mo before you change the bulbs. But you can put Anything under those lights and they'll grow.
I hope this helped you.
If you feel I hi-jacked the thread (I kinda did) and don't want it posted, pm me and I'll remove it, no worries.
Good luck and Good Reefing!
