I really appreciate al the work you guys did, especially LEDgardener. His site and videos have given me a lot of input about gardening with LEDs. If it wasn`t for him and Growmau5 I would still think that LEDs suck and are way to expensive like I thought last years until mid 2017

Ok, that's enough intro now I would like to ask something about my project.
I have two projects, one for flowering with 3000k cxb3590 LEDs and this one for veging at 4000k with LM561c. In a perfect world I would add the 4000k veg light to the 3000k to have more intense light or a bigger light spread and mix spectrums. Time will tell if I mix both lights or just go with the 3000k CXB3590 for flowering.
I was quite inspired by the Quantum Boards builds on this site but could not get hands on one until now and black firday prices made the situation even worse, anything that I wanted was sold out for eternities.
So in order to get somthing going I looked around and found Samsungs inFlux line that also uses LM561c LEDs.

I chose the biggest strip that is made of 96 pcs of LM561c (S6 bin) LEDs with the following data:
inFlux_L09 4000K
9100lm Luminous Flux
137lm/W Efficacy
66.6W Power Consumption
48.2V Input Voltage
Choosing a driver was a little bit hard as I wanted to go for efficacy but I also wanted to get a lot of light

I wanted looking for something in between 700 and 1200 mA. Well I went for power instead efficacy, still not 100% sure about my descision.
I hope I am getting the numbers right as this is still new and sometimes confusing to me.
If I use one LED strip and drive it with 1200mA and the input voltage is 48.2V then one strip would consume 57.84W? Isn't that way to much to be efficient? I also get a lot of heat and need big heavy heatsinks which makes building and hanging the rig more difficult. Would it be a good idea to get more more strips and drive them at just 700mA or is that way to low to get good results especially if I want to use my 4000k lights later in combined with the 3000k for flowering.
My heatsinks are big and chunky 120w (600mm x 25mm x 100mm), I could also place 2 Strips and drive them at 1200 but originaly I wanted to go with one Led strip per heatsink for better light spread.
Maybe the community can give me some feedback and ideas around my build as this is still some what confusing and new to me. But I am happy to be on board and to do a DIY and learn something new instead of buiying some thing pre build.
