yup, your right about the based on equivalent to other non led lights only problem with this is only the very high-end lights can you trust this rating most led light company basically lies about how powerful their lights are you really can even trust there par/ppf rating cause a lot of them have been caught copying and pasting other high-end lights par charts or they lie about distance/height from plants. this is why for so many years now people have been building there own led light setup from quality led parts from very reputable company's
for those who are really into hardcore advanced spectrums and high power for food/weed production these guys are banging that drum super hard

edit Ya that's a crazy light I just wish he would have used better cob led's cause the ones he is using are cheap Chinese cob's with a lumen per watt just over 100 I am pretty sure which most of high end cob's gives you way over 150 lumen per watt
