Ts Marshydro led 2000w

Thats a half decent light yeah. Is it a TSW or a TSl 2000?? U said your tent is longer right? remember the TSL2000 is the long thin one and the TSW2000 is the square shaped one. That will do a few plants all the way to flower no probs. If your getting the long thin one, u may want to look at this first... https://www.viparspectra.com/products/pro-series-p4000. Its a bit of a beast but would replace most if not all of your other lights. Like I mean it would do the job of your TSL 2000 and then some. For a long grow tent like yours I cant think of a better light to do most of the tent. Or this one is perhaps another option if you were thinking of the TSW2000 https://www.viparspectra.com/products/pro-series-p2500 It would do a similar job but with a bit less power used. 250w vs 300w but similar light outputs. However if those dont tickle you the right way, then there is nothing wrong at all with the mars.
