Diy FOTOP grow board 280x900x2.0mm (L29.52"xW9.18")

[Moflow]

I got these to test.
Grow Board 280x900x2.0mm
(L29.52"xW9.18") , 3.0/W conductivity,2OZ,
16S50P, 129.6-372W, 43.2-49.6V,
800pcs Samsung 561C s6 leds.

They cost an "O" for 2 boards....... £200.
Awaiting HLG 320H 48A from TME, cost a "q" ....£80

In my area I can use these as a side wall of light running soft or overhead.

This is cheap n cheerful light option for tight feckers on a budget!

Now I'll just put on my Flak jacket and hard hat and press "create thread"

Are there two spectrums? The middle rows look lighter than the outside rows.

@Moflow looking good, like the size of the board. Would make great wall to ceiling lighting in a growdrobe.
Be interesting to see how it goes on the new driver.
Best of luck and thank for sharing.

Thanks @zypheruk ,
A fast way to do it for sure. 3 wires from plug to driver, 2 wires from driver to board , position it and turn on .

 

[zypheruk]

@Moflow yeah they would work fantastic in my cab, could cover the entire ceiling of the cab, Im a scrog grower so right up my alley they are.
Gonna sit in the corner here and see how you get on.

I got the driver yesterday so I done a bit of testing.
No heatsink.
I had the board in vertical position with the obligatory black tape stuck on back of board to take temps.
Ambient temperature in room was 18 Celsius.

I ran it for an hour with both pots turned to max.

Maximum was 49.3 volts.
Maximum was 7.54 amps
371 watts from 1 board.

Back of board max temp was 63.3 oC


I got a small 6 inch fan and had it blowing on back of board. 53.1 oC

They are most likely not lm561c but rather lm561b+ as on your closeup of one led the dot appears very clearly and from what ive read/seen it is specific to the b+.. that being said its a +/- 10% effiency from the C.. i had seen those board ended up buying the 304 boards.. very satisfied and im sure you will too.. its good to know that they run cool even at max power without heatsink.. im looking to build another tent soon i may consider those big boards unless I feel like I can do a strips build.. but one thing at a time! Lol thanks for sharing man they look great

How much you paid for shipping?
