Led light suggestions for a newbie

[zoot]

Hi, newbie here, just posted my intro. I was wondering if anyone has used a HLG 600 Rspec ? A friend suggested it. I’m in the process of starting my first grow, just now setting up the space. I have a 7.5’ X 7.5’ ‘closet’ as my space. I’m about to purchase lights and I are looking for advice. With that size space should I get two of these units ? I have lots of questions but I wanted to get the lights ordered.
thanks !!
