The fotop is really nice but not ideal for a 4x2:. Inn order to cover it all you need a bit of extra watts and hanging height which also gives a bit of hotspot. Also it being so large means extra shipping, i dont think you can do this build for 300.

Can you get aluminium cheap locally? In that case id almost rec a bridgelux vesta build. They flower like insane on their warmwhite high cri spectrum.

We have a 4x2 with 12 x 2 foot vestas on hlg240 and its our best tray every flower.
Vestas are cheapish usually less than 10 per, and you can try budget drivers, meanwells elg or lrs range.

For sinking: we use 3M tape with 3mm thick, 60x30mm u-channel and it keeps everything nice, 2 strips per channel.

Vesta also has a cold white spectrum which is jice for veg, against stretch etc.

Thanks I’m happy I asked because I had a feeling that wasn’t going to work because it looked like it couldn’t cover all the edges, and I’m looking into aluminum, I was looking earlier in my process and I’m pretty limited locally pretty much whatever you could find at a Lowe’s or Home Depot and I was looking at heatsinks USA. But I will look into the bridgelux vesta. Do you have any links? I also did like the idea of a build that used a nice linear design with the strips to help get a better spread. Something like
But with other components, what do you think? And thanks again for all the help I appreciate it.

The Vesta is linked by Moflow, those photoboost strips are a very good choice too but a bit more pricey. But they only have one spectrum, not dual channel as the vesta.

I used 2 vestas per heatsink in series, 6 sinks in total on a hlg240-48A, adjusting the voltage up to 50ish V.

I suggest putting the strips across the the 2 foot section and leaving the sinks free so you can move them around till your happy with the spread.

Thanks a lot guys these look great and was pretty much exactly what I needed close to the other strips but a little more budget friendly while still be a good product. And yea I think I like the idea of even being able to slide the 2 foot cross sections around to even the spread nicely. One last thing this tent is going to be for full cycle grows so would you mix the spectrums a little what what you get for say 6 of the 2 foot cross sections 12 strips of. So say would you get all warm white ones or mix in some more cool white.

For flower, full warm white. For vegg id go for all lights on, gives a nice 4000kish light. You can also play with using both spectrums but only on a few strips.

Yea that’s kinda what I was thinking rocket. I would just got with warm but it’s a full cycle grow so maybe mix in 2 crosses of the cool light so it would be 4 strips of cool light the. On the other 4 crosses have 8 strips of the warm? Think that would be good for full cycle.

LEDGREETS to Everybody !
Took me a week to read thru the 83 pages and THANKS-A-LOT to EVBY for contributing !
Special thanks to MOFLOW and Space Comander ROCKET SOUL...

Bridgelux Vesta build : I am a happy DIY- Builder and its crazy that after 82 pages you come up
with
[/QUOTE]: We have a 4x2 with 12 x 2 foot vestas on hlg240 and its our best tray every flower. [/QUOTE]"

Does that mean that ,off today, the Bridgelux Vesta build would be a real alternative to a "Fotop 800 lm561c" build ?
(I got 4x1sqm Space with Libras on Rockwool DTW,CO2/closed room)--and yes the goodole 600 HPS humming...
The HPS are ready to rest now ...so..
Actually, I was about mailing Rita or KB for a Prize Quote / Order but your comment on the Vestas got me thinking again.. Please Advice !

Thanks for enjoying the thread!

The vestas are an outstanding strip. I rec them for smaller builds cause its a lot less work to so large scale with fotops.

The 2700k 90cri spectrum is why its my go to, flowers better than reg 80 cri. At least as far as weve seen.

But i believe you can get 90 cri fotops if you buy atl 10. But im not sure of what you will get its never 100% straight with alibubbers.

Also gone off fotops a bit cause they dont fit around our current grow plans. Its hard to fit 2 foot supplemental strips around them.

For a 4x1 m space: easy fotop build would be 2x 5 Fotops, spaced every 40 cm, 10 in total and you can get 2700k 90cri from rita. Its great for flower, in veg some people say too stretxhy (less than hps) and some say great growing vegg. Depends on how you see it.

But vesta for sure is an alternative to samsung boards: they have 3 easy accessibility spectrums, 2 which are quite usefull, 2700k for flower and arojnd 4000k 90 cri (both channels at equal power) for vegg. The 5000k id only use if i i real needed to shorten node spacing.

Also, vestas are a whole lotta diode cheap: 12 vestas both channels are 2400ish diodes. And theyre less than 10$.

I suggested it above due to fotop not being a great 4x2 options (coverage and high relative shipping on one board only) and due to budget restrictions.

Makes perfect sense its a bit like a KNOCK OFF the KNOCK OFF ! I also have a more chilled feel bout having

DHL delivering boxes from a vendor round the corner (EU_union this is, in my case) without any warranty issues..
I checked for alu metal u-channels and for a 1 X 1sqm rig it comes to 18 Eur ! Gives me the motivation to build
these "GROW BARS" Angel Wings myself (see Grow Bar jpg) : 6 wings at 1,20 m each (3,5`x 4`) the 1.20 m side could just continue endless into the sqm x row ...

When I drill perfect aligned holes thru the u-channels and hang them on bars; the holes work like a bar guide giving me the benefit of adjusting the channels spacing Its 100 % diodes coverage when the girls look into the sky I like that If you want to go insane you just keep adding channels (with no postage spent) until the sky is gone and only Stars r left lol All cabels disappear neatly in the channels and maybe a gritbox will do the trick to position the drivers on top. Talking of drivers:

The HLG-240H-48 comes at 47,90 Eur right now (tme/eu) 2 of theese will give it the touch of luxury..Driver wise..

How hot a HLG-240H-48 get if you push it to 50V ?

OK , trying to figure things out :

BXEB-L1120Z-27G4000-C-C3 : comes in 28, 56, 120 cm

Thats would be the generation 3 you talked about earlier There is a Bridgelux Specsheet online but no product
anywhere. Are these the same 2700k 90 cri Diodes that are on the Vestas Stripes ?

And I think Bignick10 implanted the " GrowBar AngelWings" Idea into my subconscious...Thanks for that!

Yea I’m pretty sure I’ll be doing the strips build. Going with ether mostly warm white or just all warm white. Then I’ll be getting a driver prob the hlg 240 for 10-12 boards. Question if I wire them in series like the other build will the 240 be okay? I plan on building when I get back in a few weeks as I am traveling till the 20th

The wiring depends also on the frame design you are using. I will wire them parallell since my strips stick out like
a forg (ecco speed design) the hlg 240 will meet them in the middle with sets of wagos.

I think gen 2 EB's are a better value proposition. Getting dirt cheap now. Should be near $7 ish for an almost 5000lm strip.

really nice pricing on the eb2, and eb3 looks sweet too, eagerly awaiting undervotling/undercurrent results for them, which lumen per watt are acheivable.

But the best light is the light what you have working for you :bigjoint:

Am quite happy with the plain old 3000K 80 CRI LM301b setups i use, have nothing to compare exept 3500k 80cri CXB3590.

The 3x3 6x288 panel HLG320 setup who draws 280W at the wall.
A little light burn here n there, but nice buds would say.... and quite some.

the 2.5x2.5 6 panel HLG240 Setup , draws 220W at the wall.

even more light stressed, maybe need to dial in my nutrient regime also a bit, VPD etc.
RH is higher in the small tent.

this could become one of the best results i had so far, my needs will be covered for some time.
