Decision round ,led system , 3×3

I recommend one Mars reflector 960W led to cover your 3'x3' grow size. It is powerful enough, their spectrum are very efficient for the bloom

If I was severely brain damaged, I could bin my latest tech, highly efficient USA made lights and replace them with a 1.3 PPFD/Watt old tech light from China & still grow lumps.

Samsung Datashed are confusing me..
I though less mA means more lm/w
(H influx s04 at 1000mA =182lm/w
at 1600mA =201lm/w
Same
F serie f284b at 1120mA =171lm/w
at 1800mA =190lm/w


I definetly want to Go with strips!
18-20× 1foot Samsung H influx cost +-222-246,-


36 - 54× 1foot Samsung F strips cost 161- 240,-
(2600-3900diods +-) :fire:

So i took the Data from cobkits for Quantum Boards and try to convert this on strips

(Qb288 v1 lm561 for f strips /
And
Qb288 v2 lm301b for h influx strips)

- 4.5 × f- strips have 288 diods like 1 QB V1
- 4 × h influx have 288 diods like 1 QB V2

-Samsung f strips1foot (lm561 )
St. Watt/panel lm/w ymol
61× a. 5.24w =320w 195.5 2.90 $?
28× a. 11.3w =320w 183.6 2.73 $?


-samsung h influx strips 1foot (lm301b)
St. Watt/panel lm/w ymol
55× a 5.75w = 320w 206 300 680€
25× a. 12.4w =320w 196 285 310€
20× a. 16.5w =320w 190 277 248€


Is that right?
