It’s important to consider that plants see a wider spectrum of light than the human eye can see and that spectrum is referred to as PPFD. Lux (or lumens) only measures light spectrum that the human eye can see. Different lights from differing manufacturers will all have PPFD differences driven by the types of components used to manufacture the lights.
PPFD probably doesn’t mean anything to a lot of growers, but there is guidance that can provide a helpful relative comparison:
PPFD for seedlings: 300 PPFD
PPFD for veg stage: 600 PPFD
PPFD for flowering stage: 800 PPFD
So lumens would look something like this. I’ve just made numbers up for illustration of a relative comparison.
Seedlings: 20,000 lumens
Veg: 40,000 lumens
Flowering: 50,000 lumens
