Photon flux density is what you look for with LED - anybody advertising or measuring by lux has no clue what they're doing or saying, almost guaranteed.

Also, I've recently heard that many LED sellers are going "240w only consumes 120w" and let me tell you this - if you get one of those units, take it apart, you will find that you're paying way more for less. You're getting 240w of diodes, but only pushing about 120-140w of power through them (one guy in a thread said he took it apart, read the labels, did the math, three drivers only pushing about 4w each in the panel.) I think it was the Lighthouse Hydro Blackstar, in fact.

Such deceptive and misleading advertising. I hate it with a passion.
I think part of the problem is that very few growers know shit about LED's, the spectrum or intensity of light they produce or anything! Myself included (tho I've at least got a clue)

So, many in the industry would seek to abuse that lack of knowledge for personal gain.

I don't agree with the ethics either, but "There is a fool born every minuet" and there are those who target those fools.
