3 to 5 strips would be ideal4sq ft, so 120-185w driver
You could probably get away with using 4 f series doubles

Is he selling both the strips and sinks ?As already stated by @wietefras f series or Hinflux strips. Double row strips. I think he uses the 4 footers.
Personally I like the 2 footers because @diyled has the 'perfect heatsinks' for them
The f series 2 ftrs prices have dropped a tad. I paid £27 A strip, they're now £19
Hinflux 2 ftrs are now £24.50 they were £27 when I got them
The vesta strips seem a bargain at only £8 with a good spectrum and 90 cri although matching a driver for them is not as simple as the Sammie strips.
lol I strongly considered buying prawns boards, but I just love my strips, so I'm gonna stick with them for the foreseeable futureOr a couple of FOTOPS for minimum wiring and a big foot print!
Can you do me a favour and double check my math for roger about those bxeb gen 2s?3 to 5 strips would be ideal
Yes, he does.Is he selling both the strips and sinks ?

Fortunately I have the "Original" disco boards from China.Yep, prawns boards are really doing well for all the growers using them over at the other spot. They have tested well and have proved themselves in Ogs side by side, if i was going the board route, id be buying Prawns boards for sure. No doubt about it.
No doubt, thats great customer service, ive seen his work, very nice lights.
haha.Fortunately I have the "Original" disco boards from China.
And I thought the Chinese were the copy catters...? Lol lol

Ask him to come visit this thread when he gets a chance, love to hear his input on all of this strip madness lol
Also post up a pic of the sinks when you can, would love to have a look, i might hit him up for some when im ready.
haha.
I only tested EB gen2 80cri and they didnt test as good as the f series £ for £. Pricing is completely different now so id have to go back and test to give a fair opinion.Ask him to come visit this thread when he gets a chance, love to hear his input on all of this strip madness lol
Link me the code and ill buy them and test them.Id still like to hear from @diyled re how faithfull these new ebs are to datasheet
Hey, thanks for the response.I only tested EB gen2 80cri and they didnt test as good as the f series £ for £. Pricing is completely different now so id have to go back and test to give a fair opinion.
Hinflux are cheap and have just been upgraded again as the voltage is lower. Id stick with them. Although the gen3 in 90cri are tempting. All comes down to you own preferences. Id favor 90cri from my own experience. But some may just want high efficiency, high Umol/£, low upfront or just want a baddass light for no real reason.
Of course the best strip is mine
Great write up only a couple of things to add:@Roger A. Shrubber
If you've built with boards, nothing really is different with strips, as far as driver selection, it's just a bunch more "boards"...
Here's what I used to do to figure out what driver to use.
Find a target amperage for each emitter(in this case a 20v BXEB 560mm)
Look at a data sheet for a MW constant current driver (stay with me on this)
Example : EBs rock at 1050ma, so a HLG-240H-C1050 has 277V available. That would allow at least 13 (maybe 14, it'd be close)BXEB 560mm 20V strips to operate at 1050ma.....
NOW.... since we really don't want to go with a CC driver with that sort of V involved, but we know that SIZE driver will run 13-14 of our chosen emitters at our targeted amperage, we look at an HLG-240-20a driver, and add 14(or more) strips of that ilk in a parallel wiring circuit, to achieve said targeted(ish) amperage!!!
OR, one could just refer to a CC/CV driver datasheet, and divide the total amperage output by as many strips as necessary to
stay in the desired range.
I prefer to build in 240w sections, even if it's a larger area to cover, I revere the flexibility of multiple panels.
would 50 of these units be enough?Great write up only a couple of things to add:
- Parallel connections can be made easy by "daisy chaining" which running all parallel connections thru the same wire. Much neater than a standard wago "octopus" which throws of loads of cables. I dont like daisy chaining cause the the first bit of wire takes full amps of all strips. This is just my personal preference.
After trying once to connect 14 strips in parallel without daisy chaining please consider the option of using 7 parallel connections of 2 strips in series, using a higher voltage driver, in this case something like a hlg240-42A. This can many times make the build neater and avoid daisy chaining.
The other thing: 240 drivers seem to be less prone to failure than 320 and above. And they are perfect for a tight 4x2.
Mid feb. New design with cable strain relief. 50mm wide so you can fit 2x single rows on there too.I was on your site earlier, do you have any strips or sinks in stock or restocking soon-ish?
Yeah i used to do 4ft and have some coming mid feb.@diyled Just gotta curiosity, did you ever get any 4ft heatsinks to try?
