LED Lights

[czappme]

I need new LED's and found some "reduced" lights, I'm growing in pots (100 qty.) in about 500 sq.ft. The ceiling is about 10 feet high. The light specs I found are
* 8' light, covering 16 sq. ft.
*210 W
* 242.40 PPFD

Wt brand led are you going with ?

At 40 watts per square foot you need 20,000w to light 500ft3 adequately for flowering.

They are selling a "boutique spectrum", eliminates wasted energy/heat(they don't use orange/yellow) which accounts for the low PPFD

That is not how it works.

Ya like the homie @Horselover fat said. I think you need to look into this a little more. I use lux 645 and i got tons of yellow and red. I hit depends on the strain 2+a light and it doesn’t get hot at all in my room. that’s why I moved to led because they let off way less heat then hps wt brand is it agin

That is not how it works.

What he said, The majority of heat is actually generated in the 680nm plus range and IR light

You should just get 200 ea 100w strips... like the f-series gen 3 https://www.win-source.net/products/detail/samsung/samsung-si-b8uz91b20ww.html

Then just use 4040N1 aluminum extrusions as heatsinks.

4040's are thick enough to where you could run 2 strips for each row. So for every 6 rows your coverage would be around 8x8ft, or 2 4x8 trays.
