Nope! It's perfectly fine to run them at the drivers maximum. As long as your grow area stays around 30°C there is no problem. The maximum one FB24 strip can handle is ~170w, if you drive 3 of them @ ~2,5A each they run with ~125w.
If you look from this POV at the numbers the strip run only at ~65% of it's maximum ratings when fully ramped up. With 45v it's probably only 25% of their maximum.
Edit:
Mount the driver at the wall outside of the tent in a vertical orientation at best. This gives best convection and is safer as a plasic box.

I was hoping you might be able to help as I am going to purchase some of these boards so want to be sure get right parts as they are pricey as are drivers to run them.
What model of mean well driver would one get to run the max these strips can run at along with how many strips on that driver?
Series ?
was thinking about these 600 watt(not sure which model is best suited thought)
https://www.meanwell.com/webapp/product/search.aspx?prod=HLG-600H
or maybe 480 watt?
https://www.meanwell.com/webapp/product/search.aspx?prod=HLG-480H
Thinking about shooting for 100 watts per strip is that reasonable? or better to run them a little softer/cooler 80-90 watts?
they will be on heavy aluminum frame, will remote mount driver outside tent.

or maybe 480 watt? 5-strips?
100 watt F-series strips, there are two kinds why the huge difference in price any idea?

also wondered if anyone had feedback about this strip?

I do favor sammy 4 foot strip though, but Thompson research strip look very powerful for price/size.

I don't see any info on what make/model diodes are being used in that TRP strip.

yes I know, shame seems like a powerful strip .
Likely stick with Samsung as I like the QB's I already have.
Never hurts to save a few bucks when you can though.

For 600w you can use an HLG-600H-48 and a minimum of four 4ft doublerow F-strips connected in parallel (or 8 single rows). The HLG-600 has 2 sets of DC wires you simple use 2 strips in parallel on each side.
If you want to drive them lower you can also use 6 or more strips in parallel. The more strips you use the better the efficiency. @2240mA(125mA per diode) you'll get ~2,3μMol/j from LM561c, but if you use 2 of them and drive them with only 1050mA(~62mA per diode) system efficiency would increase to ~2,5μMol/j.
There is no need to add more blue to the spectrum white has already enough blue. And red/blue only is outdated and fits only for leafy greens. I would rather take the Emerson boards (QB16 I believe) from HLG. These would add red, deep- and a bit far-red to the spectrum. Fits much better as supplemental light for a white spectrum.

I actually have 650+ watts of 3000 k v-2 QB 288's so this is more a veg light.
Any idea which is the most powerful of the 2 row f- series four foot as I keep finding different data on Arrow and Digi ?
Price is all over the map in Canada digi for some reason just hate out lay out 500.00 for strips a don't get best for application.
Any suggestions?

In earnest?!
There are only 6 versions; 3 single row and 3 double row in 1, 2 and 4ft length. I'll add the datasheet below.
Double row 4ft F-strips is the most powerful and can run with up to 170w(3,6amps/48v); nomimal its 103w @2,24amps(46v). For veg only use 4000°k, for veg and flowering use 3000°k. The ones available/in stock are usually cheaper like the ones you can only get for bulk prices.
If you want them for vegging and you have still a bit time consider to wait on the new Samsung horticulture strips. Efficiency would be 2,74μMol/J(LM301h + LH351h) compared to ~2,3 with hard driven F-strips and their 5150°k spectrum(5700°k + 660nm) is pretty good for vegging.
For flowering mix them 1:1 or 1:2 with warmwhite strips; H-influx or F-strips.

Thanks!
Great help.
I just got some pricing and am considering going with 10 of SI-B8VZ91B20WW Samsung Semiconductor LED MOD FSERIES GEN3 3000K STRIP double row 4 foot..
Wanna run 10(or more if needed) in series make two- three lights any idea what driver to use? maybe 3-HLG-600H-54A ?

Do yourself a favor and wire them in parallel. These 1oz copper boards are limited to 50v and if you connect them in series there will be a certain voltage droop the driver has to compensate. This means you don't get all the possible output.
Also the HLG600 is only available as CV/CC version.
Wire the strips in parallel and use HLG-xxxh-48A or B. With both type of drivers the strips would run in constant current mode. A CV/CC driver switch only in constant voltage mode if you set the voltage higher(A-modell has voltage and current regulators) or if you use them with secondary DC to DC drivers like Meanwells LDD's.
You also get more output from CV/CC drivers compared to CC only drivers and in the end its easier because you can add as much strips as you want in parallel.
Another thing are these onboard connectors. 10 strips in series means ~440-450v and these connectors are only 300v rated.
You see, there are a few good reasons not to use a CC driver.
You also don't have to worry about thermal runaways. With the A-model you can limit the voltage maually and set it to 46v for instance. This way the maximum one strip can get is ~1120mA and even if 8 of 10 strips fails the 2 strips left would be still limited to 46v and ~1120mA. And the B-model can not go higher like 48v! If 8 strips fail the 2 left would run with ~150w which is still in a safe range.
The bigger drivers are also more expensive compared to 2 smaller ones with comparable output. Two separate fixtures offer also much more flexibility. For instance when you grow different strains. Canopy distance plays a big role!
I for my self tried it with series connection of 10pcs 2ft strips in series(only 230v max.) on an HLG-240H-C1050B and theoretically I should get ~240w minimum. But checked with a wallwatt meter it were only 186w at the wall. This means the driver was not able to compensate the droop which occurs because of the small 1oz copper traces.
Now I've wired only 5 strips and 2 CRI90 COB's in series but several strings in parallel (5s4p) and instead of 350w I only get 325w out of an HLG-320H-C1750B. I can live with it because its enough but next time I will use parallel wiring from the beginning.
Samsung don't mentioned the V50 limits in the F-strip datasheet but its mentioned in the H-influx datasheet and I'm pretty sure its the same with all 1oz. strip PCB's.
You could use 2 HLG-320H-48A or B and 5 double row strips per driver. The driver has 6,7amps so each strip would run with 1,34amps. Each diode would run with ~75mA which is an efficiency of +180lm/w. System efficiency maybe 2,35-2,4μMol/J.

Thanks so much, I need to do some research on what you have written but I have a basic idea.
Would this work on either of the two strips below??
HLG-320H-48A
will go with either of these two strips now , can't decide.
12 of SI-B8VZ91B20WW F-series double fow 4 foots (3-320 meanwells to power)
24-SL-B8U4N90LAWW- (2' H influx double row) (3-320 meanwells to power)
what is diode on this strip any idea? Good efficiency
one last newb question, can you mix strip same forward volts same type say some of these mixed in?
SL-B8R4N90LAWW
with
SL-B8U4N90LAWW on same driver?
