to me they don't have the same coverage or penetration, but I'm new to LED so could be wrong. My 2 seem to have about the same coverage as my 600w, but more even coverage instead of spot light in the middle. The light seems to fall off immediately on the sides, so anything directly underneath looks amazing. I don't have the proper tools to measure the PAR though sorry.

They say the flower footprint is 5x5, I struggle to believe that. With a ppf slightly higher than a 600w hps and only 450+- watts I think it would light up a 4x4 well but struggle with more.

I read its actually 410W from the wall. Migro had it at 2.0 umols not 2.7 like they claim. I still think its a good light. Better than Mars.
Should work fine in a 4x4 anything more is pushing it

Running 2 sf 2ks right now in my 4x4 just about to flip to flower we’ll see how it does but like previously stated around 410 Watts from the wall leaves me a little nervous but should be fine with 25ish Watts psqft....my girls seemed to like them in veg
Apparently, we want closer to 50w/sft
If you can move your plants and light to one side of the tent

Being as small as they are I do have them both pushed towards the front of the tent and for other reference it’s only 4 plants even tho they won’t be crowded I have a feeling I’ll be ordering another 1-200 Watts to supplement
