switched to led now (apollo 10 370watt) will i get...

That would depend on how much you yield under 600 watts HPS, usually most people get between 50% to 80% efficiency (300 grams to 500 grams) and some highly skilled growers get to 600 grams, so the usual range of yield is 0,5 to 0,8 gpw and some up to 1 gpw. For LED’s it’s easier to be closer to 1 gpw, most grows I’ve seen, get between 0,8 to 1 gpw, some even going up to 1.2 gpw, mostly because they put out lower heat and so it’s easier to get the plants closer to the light. With 370 watts of LED you should be able to get 300 grams easily and up to 370 grams. If you are achieving close to that with HPS, you most likely will get similar results (similar yield in grams, different efficiency in terms of gpw), but If you are getting over that with HPS, you will not get the same with a lower power LED. Light types and wattage only gives you a possible yield, the rest is up to your skill in plant training, transplanting, watering and how full and flat you can get your canopy. Sorry if I can’t give you the answer you are looking for.
