The 2 I have cover a 4x8 for space. (One for each 4x4 foot space) You would still need 4 minimum to cover your 10x10 foot space. With or without the light movers they could cover that space better than the HLG 550 model. With the light movers it would cover better for flower.
The HLG 600h can be bought pre assembled or you can save $69 per unit if you assemble it yourself.
As tall as you want …taller is not better you want your plants to go <----------->
No ^

hey I’m including here to just confirm if this will be good for me.
so 10x10 tent with reflection built in.
for 5x5 section A I plan on getting the confirmed decent HLG-600H QB, which says it covers 5x5 both for veg and flower. Is that going to be too little light? I should use 2 of these HLG-600H boards to properly maximize coverage for 5x5 or one is enough?
For the 5x5 section B i’m looking at testing out one of the better chinese companies, most likely kingbrite.
They seem to have so many listings that are more or less the same so its difficult to know what to choose.
here is one:
Here is another one from them not sure what the difference is?
So for these ones frrom kingbrite they say it can veg/flower 5x5… BS?
I need 1 of each or 2 of each for proper coverage of 10x10 tent?
Finally there is a 3rd option which is these bar style lights… Found one from “Ecospeed LED” on Alibaba… They have upto 12 bars… for sure 1 would cover 5x5 no doubt. What about the quality etc?
I dont think I can post links here is the title search yourself: 2019 new products patent design ETL approved lm301b lm561c lm301h lh351h led grow 1200watt 10bars 12bars 8bars

more info:
QB board style seems everyone says you can get good end results, so I want at least one authentic HLG in my setup so I can refer back to it as I learn, but I'm happy to get 1,2,3 of these other boards as needed to test it out. All other factors will be the same so it can be a good test for these lights.
I personally think the last one from Ecospeed has an interesting really big design that could cover the whole area well with insane light, but not sure about the quality and I’m a total noob so perhaps I’m missing something and its not relevant or other QB style kingbrite is better…
Main thing I know is it should only use the Samsung LM301B/H diodes, and extra 660nm either osram or Cree, UV and IR help as well… umol should be as high as possible… (was told really high umol means you should also get CO2 compressor ? happy to ablige if someone can confirm.)
I’m ready to buy it all today so any insight if its a good purchase would help me get this step out of the way…
Also in interested in general on that rail device thing that moves the lights back and forth. Even if I get 2 of each for max 10x10 coverage there are always dark spots etc so moving light could help even out the penetration…
thanks !
I’m not really up to speed with all of the knock off lights. They’re probably good enough, but I don’t know for sure. If they perform like the hlg-600 kit, then 4 of them would be pretty reasonable in a 10x10.
thanks for the response but must say was hoping for a bit more elaboration - but free info of any value is really appreciated 
(I am a consultant so I understand well the dynamic of asking for information all too well!)
When they say can veg/flower VxV, what does that mean technically? I know umol is a standard in a way, but what defines if its 4x4 or 5x5? PPFD or Par out to a certain range? What is the lowest PPFD or par or whatever reading I need to do to decide if its ok to grow at that distance? Also what is the highest you should go?
Light spectrum for veg and flower generally means the spectral distribution is such to promote healthy growth from seed to harvest.
Sometimes shady light manufacturers will just throw a random number out for coverage, without any data to support. Recommended light coverage should be calculated using daily light integral. Amount of light over area is the formula for ppfd. once you can determine the ppfd average you can multiply the amount of light by light hours to determine amount of energy plant receives. There are light saturation points that vary based on co2 levels as well. Based on running 18 hour veg schedule a ppfd average around 400 umols/s on ambient co2 is about ideal. If running 12 hour flowering schedule, the light time is reduced by a third so you have to increase light intensity to hit same DLI. Ppfd average of 600-800 umols/s is recommended for flowering plants on 12 hour light schedule.
You basically need total radiometric flux and size of space, then you can crunch numbers. I would love to elaborate more on those lights, but I don’t really know much about them or the vendors. The one light says it will run 3 umol/joule, I find it very hard to believe unless maybe dimmed beyond any useful level. If it runs there full power would be the most efficient grow light available barr none.
3 sounds suspicious to me the hlg600 is 2.51 and when the mean. Bigger space for veg is because plants can get away with much less light in veg as there not building all the complex canabanoids in droves yet so veg doesn’t need much at all pretty much anything works in veg lol
i assume many wouldn’t understand everything you said but it extremely helpful for me thakns Ya 3 umol sounds like chinese talk lol
I’ve always been under the impression that our plants need less light in veg because the light cycle is longer. 400 umols/s for 18 hours is about the same DLI as 600 umols/s for 12 hours.
I literally use alot less light by using cfls so I dunno for optimal maybe around those numbers would be beneficial but I grow everything under a single 400hps 4000k right now and thay have all out grown my space that’s y I moved em to the new space
If you really want to give a chinese company a try, then you should be looking at Mars Hydro’s new SP and TS line…
