F strips or HLG QB132?

I'm torn between doing a build with samsung F strips and the HLG QB132. At first I thought it would be cheaper to go with F strips, but the heatsinks are making that not the case. I'd get 48 more diodes with the F strip build but the QB v2 have the newer chips... Seems like it makes more sense to go with the QBs but not as fun of a build. Would get pretty much the same flux for cheaper with more efficient diodes. Any thoughts why f strips might be better?
 
More f strips driven at less watts, no need for heatsinks with more strips. But hlg quantum boards are as Easy as it gets
 
Do you know how low they have to be driven not to require heat sinks? And would you just mount to angle aluminum? Seems like U channel is basically as expensive as the 1" heatsinks
 
The strips were originally designed for commercial lighting. They will operate within specs in essentially 'free air' at test current, so the FB24B's are good to 100w. They will run close to 50degC like that, but a simple .100" aluminum strip used as a backing plate will reduce that substantially.

U channel should not be that expensive,

2.5m for a few quid.

Im considering a strip build next, would like a nice led setup for veg and I already have 4 288s and 4 132s from hlg all at 3000k in my flowering tents.... What's your guy's take on this article?

I thought people always said bridgelux was garbage but people put them at #2 on this list. I'm still probably going to do f series but still interested to hear what others think.
 
Honestly, at this point, I'd let price and availability guide my decision.
The difference in efficiency is so close it's moot.
 
I went with the QB132 build because it ended up being fairly cheaper for better efficiency and output. I heard bridgelux was pretty good, you just need more of them compared to F series

I'd go on price and versatility, what voltage are 288 and 132s?
I'd get a strip light with matching voltage, so I could use same driver amongst all my lights. I have like 3 drivers all 24 volts, I have like 6 different fixture.
2*2 with 10 strips
2*4 with 13 and one with 7 strips
2*3 with 8 strips
And several others, 3, 4, 5+ clones, veg, what ever.
All my driver have dimming pots so I can run any of my lights with any of my driver's.

That's the benefit of using same lights/volts etc. Good luck with your build and purchase. I went with f series, because they're the best.
Nah, it requires way too many EB's to get same wattage

Im doing a continuous grow so using the same drivers isn't necessary, I already use different drivers for my 288s than for my 132s. I have 1 hlg 320h c2100a powering all 4 of my 132s which are 36v max and 2 hlg 240h c2100s each powering 2 288s which say 52+ max voltage .I'm just using t5s for all of my veg at the moment I think it might be nice to use leds for mid to late veg let the plants adjust to them before going into flower.

I guess having the same drivers would be nice in the case of one burning out or something though.

How many t5s you use to veg, and how many watts do they use. Also, how big is the space
