My light is 6.5 feet from floor and and 5-5.5’ from top of pot. Largest plant I grew in there was SCROGGED but still 2.5 ft from light at harvestThats a lot of power, did you use any extra co2 or something?
I don’t see how it’s possible to run 480W of light from a new LED in a 4x4 without burning them. But i take your word for it.
I’ll do a measurement in a bit to see how many ppfd I get if my lights are fully turned on and I’ll give you the distance as well.
Okey, I say the same to you. 480w it’s a lot of wattage, maybe it’s needed if you grow photoperiods but not with autoflowers under 20 or 24 hours a day. Or what kind of autos do you grow that can handle that much light?
I have my lights at 23-25% and 125cm to canopy. But then I’ve got 3 lights in 4x8.
It could also be this strain that’s a bit sensitive, as they got burned with higher intensity.
But I’ll crank them up soon and we see what we got at 125cm.

But I believe that only applies to iPhones also make sure you have the correct lights selected
