Full spectrum high output LED actually yields 4 times more than HPS per actual watt.
1000 watt HPS yields about 500g’s while Spectrum King yields 500-1000g’s while only pulling 460 watts.
High output LED cost half as much to run while yielding twice as much as HPS. It’s kind of common knowledge in growing now, not sure where you got the info on high output LED, or if you’re thinking of the wrong type of light (normal onboard LED), or if you are just joking because again it’s kind of common knowledge these days that LED yield twice as much per watt than HPS.

By the way, lumens and PAR are irrelevant to growth, it’s all about how many photons are reaching the plants. Reading lumens isn’t an accurate reading of photons.
