Grams per watt on leds / side question are my leds good

Hi there , bought this led light 170 watts https://cre.science/en/product/the-halo-fluxengine-x4/ and the seller told me that it is in fact better then a 250w hps and it says
you can reach almost 1000 µmol/m²s PPFD on 60×60 cm that is the size of my tent . So with that , good ventilation, temperatures ,humidity , a full line of organic fertilizers (biobizz) good genetics from dinafem (og kush) , and a good plant to fim that was fimmed . how much should i expect to get .

Ive seen people taking for example one gram for watt from hps i imagine its different with leds ?

Also as a side question , are my lights of good quality, they have all that datasheet about spectrum and other technical points but they now started to sell bars with other spectrums and i was advised to buy upon question on the new bars to put in center one bar with far red leds what u guys think they also have blue ones !

The light should be capable , but your the weak link been the grower.
No light automatically gives you X gram per watt, its all about the environment , training, strain and consistency.

I know lots of people growing with HPS that cant pull 1gpw and others with LED, the exact LEDs I loaned them that I pulled up to 1.7gpw that are still not pulling 1gpw

Bit of effort and you could get 1.5gpw or over, lots claim 2gpw but for every one ive seen that looked legit theres ten guys making the claim that are full of shit.

You don't need reds. Yet to see any definitive proof they make much difference. As far as side by sides go.

If you dont even have a baseline as to what youre able to grow its very hard to say how much.
G/w is a bit irrelevant nowadays as the watts to make decent lightlevels differ mainly in how much you budget for efficiency and how well you spread the light. If you can light your space efficiently at 30w per foot youu can do 2 with a long flower strain. But if you need +40w to light your space this gets difficult. Also some will count the watts in system some juust at board level, some just based on driver rated watts (240 for a 240w driver which actually runs 280w)

More relevant is g/foot.
Getting more than 2 ounces per square foot is good and with honing skills you may be able to get this but probably not on the first round. Hope for about 1 ounces per foot on your first go and you might get surprised buy getting more.

Running a 1000ppfd cannopy with organic fertilizer can be tricky, its easy to get deficiencies like that as the plant grows faster than what you can feed it with org nutes. Not that im an expert on org but ive seen a few around fail with high intensity leds and organics. You need to have super control over environment in order to get transpiration on point. Use 81-84F for temps and around 50-60% RH.

The light looks good, 560 diodes for 150w is considerably better than the standard 240 for as amny diiodes as efficiency goes up the less watt per diode. You do not need any reds oor blue but it can help once you haave the basics right.

The typical rookie misstakes with led are over lighting, over feeding, over watering and not paying real proper attention to climate, or just treating climate as they would a hps grow: too cold and dry.

Even better would be per squarefoot and week of flower. Weve done 2g/w 60g/foot but with 10 weeks flower which is not the same as 8 weeks.
