Hi all!
I am hoping you'll be able to give me your 2 cents worth on (yet another!) strip build?
I've been trawling the site and others and feel like I'm getting a clearer picture of it all (at least on paper!) Just looking for some confirmation and any recommendations you may have before I dive in.
The set up is as follows...
Two 1120mmx420mm fixtures each made up of six EB GEN2 1120 35K wired in parallel. Spaced closer to each other on the sides to even out output.
Each fixture powered by a ELG-240-42A.
So driving @ 50%; 39V, 4.2A, 163.8W, 26,680lm
and @ 68%; 39.7V, 5.7A, 226.2W, 39,000lm (these figures roughly extrapolated for max driver current of 5.7A for the ELG-240-42A. The ELG-200-42A is also an option if running @ 57% works? Just eyeballing it maybe 6500lm/sqft, 37W/sqft?)
For each 1120x420mm coverage (around 5sqft) I get...
@50%; 5736lm/sqft, 32.7W/sqft
and @ 68%; 7800lm/sqft, 45W/sqft
I'll stack these fixtures and try different intensities/heights to see how plants respond.
So thats it! Another couple of queries would be;
Cooling? I feel like this'll be a fairly efficient setup so its my understanding that running @50% no cooling will be necessary. Although @68%, possibly. Another forum suggested a thin sheet of aluminium would do the job.
Adding red/far red LEDs? I'm guessing for each fixture 4 Solderless CREE XP-E2 Red LEDs on for 10 minutes at the end of the "day" would suffice? I'm still researching this but I'm guessing that they'd need their own 12V, 2Aish driver? I doubt I'll add these. Just curious as to what the forum thinks about having these as part of the setup.
EB GEN3s or others? A worthy upgrade? Its my first build so even though I want it to work well I'm not looking for the best on the block. The 12 strips come to about $128US, and the 2 drivers around the same so approx $250US+shipping (NZ, so well see!)
Cheers all
