Are the spider farmer sf4000 a good led grow light

Thinking of getting a couple sf4000 grow lights... just wondering if anyone is running them or has any input on if they are a quality light or not thanks...

Im pleased with the 2 sf2000 I purchased, no issues with arrival/setup, very light weight and much cooler than the 400w MH they replaced.

Wondering if they will be close to equal of the 1000w hps ?

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.

I was looking at this light as well. Seen some PAR tests for this light done on YouTube from a couple reputable guys and both say this light is more than sufficient with a footprint big enough for a 5 x 5 tent.

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.

So what your saying is one of these lights will flower a 4 by 4

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
