3000Kevin,S6,CRI:80, 250w@

48Vf dc @5200m/a ,

2 mm thick 490 grams

just hooked one up last night

like the coverage and intensity

have few more items on the way

will start a thread on the led strips i should have this week

1170*20*2mm, 2.0w/m.k,160pcs Samsung561C，

3000Kevin,S6,CRI:80, 70w@ 48Vf dc @1460m/a

cannot wait to build a 4ft x 4 ft10 strip 700 w grid that will run at 500w

OLD MOTHER SATIVA · May 22, 2017

hooked it up@240w

and near the fan low 40's c
i had fan holes drilled in them just in case... i like air movement these kind of fans give to the canopy

i have heatsinks being made
first will be non IP65

going to try 120 w hooked up to it next

I wish to have a grow tent with al the sides covered by this panels...like that old phototron grow chamber on steroids....

Hybridway · May 22, 2017

Awesome! That's where it's at. Even coverage.
Nice work! Been waiting on this.

Looks nice set the trend for diy

Apologies if you already mentioned somewhere else but where did you get these made and how much $$$?

I don't think the intention is DIY at the board level for these, I presume we will see them for sale somewhere (soon?)

OLD MOTHER SATIVA · May 25, 2017

Yes ..thank you

OLD MOTHER SATIVA · May 27, 2017

next test here is hooking up 4 of the 6 x 22 " @250 w panels on a 4 x 3 grid using the same 600w
that is being used on the 10 @70w strips..
and taking readings of how well it covers a 4" x 4" area from the best height

also will try one over a 2 x 2 area
and two over a 2 x 2 area
[after fishing anyway]

have 2 panels running now elsewhere at 120w each over a 4 x 4 area with plants under them
they are happy but it is obvious they need more wattage..
i gotta order a few more drivers on monday

OLD MOTHER SATIVA · May 28, 2017

Next

4 x 6" x 22 " 250 w panels driven at 480W and 600W
when it gets set up
will just have fans on top until get the heatsinks

OLD MOTHER SATIVA · May 29, 2017

hooked the 4 x 6 x 22" 250' in the photo above up to two hlg-240-48's

with air moving by them they were only warm to the touch at 120 w each..

i think the boards could be closer together because the foot print like in the picture was more than 4 x 4 uness i move it close

480 w seemed like it was good enough..

with the panel placement like this frame 600w should cover more than 4ft x 4ft

CobKits · May 29, 2017

why dont you just mount 2 together on a frame then you can control frame to frame spacing easily?

Very nice! I want one like that w/ 6 of those panels in 3k running @ 700w. I'd also like 2 thin strips between them running a mix of 630,660, & 730 nm as part of the 700w.
Could you also use a 1/16" trowel & thermal paste the boards onto the sinks.
Thanks bro.!
haha! Fo-Real though!

i plan on doing that too ,these were handy..i can space them differently on these

thanks

hybrid:
i want to try six boards on it too..these are 3 k..

i like the reds strip idea..i almostasked them tonmaken me some..but this is enough for me..since i have basically only used
led to veg while i weaned myself off hps..

thanks for the trowel idea..the sinks i have coming have attachment holes
it would take a to of expenive arctic silver

thanks

waiting for drivers..going to mount fans on each panel today..

I use the grocery store key discount tags. they work great for spreading arctic silver.

I've always been a believer in Arctic Silver paste, but not anymore. Dow Corning TC-5022 thermal paste beats AS 5 it by a wide margin. 4 times the thermal conductivity at less than 1/4 of the cost per gram:

I won't buy AS again.

did you read the article? they didnt come to the same conclusions. they predicted in most applications that the difference would be nominal, it seems AS MX4 and the dow components are similarly priced in the small quantities we use them. Dow does look like a good product though, ill order some up and do some real-world testing
