QBs - Setting up a room - HLG or ..?

Hey guys, moving from the outdoors this season and setting up a room for a small indoors grow. Been following these QB leds for a few months now and it looks like most growers are loving them!
Im setting up a room thats a 12x12. This room will be both veg/bloom for the moment and i need some advice on how many and what QB's i should get. I was thinking on 4 of the HLG550's, but any advice or recommendations would be much appreciated! TIA!

That's equivalent to four 6'x6' areas. Four HLG-550s won't be enough. Think 8'x8'.

On a sq. footage comparison, you will be working with 9 four by four squares. I'm pretty sure that they suggest a single 550 for each. If you want to have adequate PPFD over the entire space you're gonna need a bigger boat...

Got it. The 4x4 measurement per light will help to figure things out depending on the size of the space used. Thanks for the reply guys.
