help please going from led to hps

so currently im growing in a 4x4 tent medium is fox farm mixed with some cocoa coir and a little more peralite for lighting right now im using 3 viaspectra 600w lights. My question is if I get 1 1000 watt hps will that throw off the same amount of heat as the 3 led that im currently using?

1000w HPS in a 4x4 is def gonna require some heat management or ac. I run a 600w in my 4x4 and now that the temps are getting warmer outside, its already becoming an issue with temps rising too high in the tent.

1 watt converts to 3.41 btus per hour.

so 1000w hps = 3412 btus an hour

Im not sure how to do the math on the 600w vias, i assume they only draw 180-200 watts from the wall, so i guess it would be 600 x 3.41 which = 2046 btus per hour...as i said tho, not totally sure if thats correct for for leds.
