is this unreasonable?

2 600 watt sunpulse (6.4k and 3k) for a 4x4x6.5 tent or is it too much?seen thousand watters in a space that size but i want multiple spectrum i cant get from just one light. would i be better off to run the 6.4k for veg and 3k for flower on a single 600 or perhaps dim the second light to a lower setting?

ok with vetalatoin you can do it, but you said one bulb cant do it, well it can research hortilux 1000 super blues its a 600hps and a 400mh in one bulb
easyer to cool with one vented shield and its a bright mofo
