Hello I have been trying to research more about LEDs and I keep running in to "Next Generation" and "5th Generation" as well as others.

Tried to do a search and found nothing to satisfy what the differences are.

I know there are some knowledgeable people out there who are making LEDs like Weezard and others that are just using them like Str8outtaweed.

Do you know if 630nm is better than say 670nm? Is there a difference?

What is the best for the blue 400 or say 470nm?

What about yellow and orange?

I am confused about lumens I have read that a Flowering plants need 10K of lumens per sqft. Yet the LEDs are not producing much lumens.

How can this be and produce?

How can a 300w LED be equivalent to 100w HPS?
