Size Grow Light for "Grow Area and Plant specific Growth Stage"
Grow Light Sizing Chart
Your 3' x 3' or ~ 0.85 sq m area requires ~ 680 PPF fixture at ~ 280 Watts for ~ 800 PPFD coverage...
To avoid "Heat Sinks" the LED strips must run well below 50% max rated Amps (Watts), some stiffening is still required; Aluminum Sheet, Bar or Angle...
Some Calculations:
3' x 3' = 9 sq ft x 0.093 m2/sqft = ~ 0.85 m2 (sq m)
200 PPFD (seedlings / cuttings) * 0.85 = 170 PPF (umol/s)
400 PPFD (Vegetative) * 0.85 = 340 PPF
600 PPFD (Veg / Flower) * 0.85 = 510 PPF
800 PPFD (Flower, CO2 enhanced) * 0.85 = 680 PPF Fixture
680 PPF / 2.5 PPE = 272 Watts
(2.5 PPE is the nominal efficiency of ~ 167 Lm/W)

Bridgelux Gen 2 3500K 560mm 2390Lm (35.8 PPF), 175Lm/W (2.625 PPE), 19.5Vf, 0.7Amp, 13.65W
680 PPF / 35.8 PPF per Strip = 18.9 Strips (~ 20 strips)
20 strips * 13.65W per Strip = 273 Watts
273 Watts * 2.625 PPE (PPF/W) = 716.6 PPF

Notes:
1. Grow Lights should be "Sized" by Grow Area and Plant Specific Growth Stage... download/file.php?id=5049
2. Nominal Efficiency of current LED Strips is ~ 2.5 PPE and the LED Driver "Sizing" factor or multiplier used is 1.25 (125%) of the LED's Watts for "Reserve Capacity".
3.Older "Watts per sq ft sizing" was based on ~ 1.7 PPE (1000W HID / 25 sq ft)... e.g., 40 Watts / sq ft @ 1.7 PPE ~ 68 PPF / sq ft ~ 732 PPFD .
4. At a nominal 2.5 PPE (LED) * 40 Watts ~ 100 PPF / sqft or 1076 PPFD
5. Samsung and Bridgelux LED Strips run below 50% maximum current require minimal to no heat sinking...

Awesome topic and information! Would the above mentioned led strips outperform those which are described in the DIY LED Strip Build Designs for Samsung H-Series, F-Series, Q-Series, and Bridgelux EB Gen.2 topic from 2018?
So an improvement over the five times f series gen 3’s?

It is about the “same“ as 3x3 using 15 Samsung 560mm H-Series LT-H562D Strips with a 320 Watt LED Driver and the 5 Samsung 560mm F-Series LT-F564B Strips with a 320 Watt LED Driver. The Samsungs produce ~ 52,500 Lm Compared to 54,500 Lm from the Bridgelux.Greenleafs wrote: ↑Mon Jun 07, 2021 10:58 pmAwesome topic and information!

Also the 3’x3’ build with 20 strips (560mm) or 39 - 42 strips (280mm) are running “Soft” (at up to ~ 300 Watts) and require minimal heat sinking.
BTW, you could increase the efficiency of the Samsung Strips Slightly by simply increasing the quantity of Strips, increase the efficacy.https://ledgardener.com/diy-led-strip-b ... bridgelux/
“ 3’x3′ Grow Space Builds”
Hi, when I built new smart strip lights for a 3x3 area, I used the services of specialists because I tried to do it all according to the advice from the forum. Nothing worked for me because I had no experience in electrics and connections. So if you are not sure, it is best to contact the specialists, especially since I know that their services for installing LED strips are not so expensive since they do not work there for a long time. However, I saw that a screenshot with a detailed installation of led strips was already sent to you here. To be honest, I don't understand anything at all. I don't know how you will do it yourself.
