Light for 4x4

I currently have a 240w farmlite led and moved from a 2x2 tent to a 4x4 tent will I be okay to just grab another 240w farmlite and run them both inside the 4x4 for flower?? I’m not to good at understanding the PPFD and par and such. Also on a budget and don’t have 300$ + for a new light atm. Any help would be appreciated Ty ahead of time!
