New loft build 4 x 2 LED (lm301) (xpg 3)

Here is my little design for my home build thanks to some wise folk on here.
All their knowledge and insights have made me move from Migro 100 to my very own homemade LED light.

Samsung lm301 are the strips(so2 3k)

Big red circles are Cree xpg-3 deep red (G01 660nm) 4 diodes on a round pcb.

Small red dots are Cree xpg-3 deep red (G01 660nm) 1 diode.

Purple triangles are Cree xpg-3 far red (G01 730nm) 4%

Green circles are representing the plant's position.

Height is my enemy being loft grow.

Hoping this design will help stretch in the lower par areas with the far red placement.

Boost red zone directly under each main cola.
With single reds to boost where the par reading will be lower.

Plan to use hlg 185 to run the lm301.
And another for the reds.

If possible build two frames one for white and another for red.

That way I can run a rail straight through to 2nd bloom room, same dimensions. Run 12/12 in bloom room 1 then to the bloom bloom room 2

If I have two frames can move the white in the other bloom room, seal it so no light leaks.
Keep the reds in the bloom room for 15mins for emerson effect, then switch to the other bloom room.

Might scrap this as it seems too much effort. And I have no experience or real evidence that doing this would make such a huge difference on yield etc.

Use the migro 100 for another veg room.

Driver needed for running 12 strips.

Not 100% sure before I purchase.

Min 1.0a Max 1.6a

Min 10v Max 13v

Min 10w Max 13w

12 strips max power 156w

12 strips Max fv 156v

HLG 185 C1400A max 143v (parallel)

HLG 240 C1400B max 173v (series)

Any advice on efficiency, which is better to run at cooler temperature. If I want to add more strips at a later date etc.

185 pulls 200w from the wall ?
240 pulls 300w from the wall ?

If this is correct, then I presume running in parallel would be more efficient.
My concern would be heat over flow.

Would both drivers emit the same light intensity as maximum amp on strip is 1.6A.

With the 185 1400A I can increase it to produce then extra ampage needed?

Any help would be appreciated

Finished the first set of lights.

Pictures available if anyone wants to see them working in grow room.

I would like to see your set up

Using Meanwell HLG 185 C1400B to run them.

Very nice. Good luck and happy growing. I am working on my 1st grow.

Yea I just ordered a 600w light but was told probably gonna be to strong for my tent. So have to figure out something else with limited room

Nice, good luck also. Not a fan of the coloured lights. Good for veg, not that good for flowering.

My set up is 3000k Samsung S02.

Cost 100 for lights strips, heatsink and extrusion 50 and driver 50.

Easy as to put together.
So much light and uniformed .

My set up is tiny.. 4 x 2

12 strips 4 on each heatsink 30cm wide 120cm long.
Using 2 of them. 2nd build be ready once they grow some more.

Nice. Ill be watching. I do have a smaller Led thats not very strong. Its not a colored light but it barely doesnt fit in my tent. Gotta get creative

PPFD 582.95 @ 200.2W Efficiency 2.9118

Using a crap lux meter. So take the efficiency with a pinch of salt.
Probably more like 2.4

Forgot to mention the 12 strips run in series.
Most efficient way. Meanwell 185 C1400B.
1.4 A is plenty and maxes out the driver out at 200.2W.
These strips can be run at 1.6A but at a loss of efficiency.

Nice setup! I've got a pretty similar setup in my loft, 2 4x2 cabinets.

Finally got 2nd light finished.

Update 2nd week starting to flower.

Tent 1
Photoperiods waiting their turn for freebie autos to finish.

Nice build. Out of curiosity where are you sourcing your heatsinks? I’d like to find some other good vendors. If those have 301s in them are they the Samsung q series strips? Looks like it seeing as how you’ve got a shitload of them lol. I ordered my strips with 301s from a grow light company, and they have deep red supplementation as well.

I also have two f564b strips in my rig and they really crank, but they have lm561b+ chips. The only light I’ve built recently was a little single strip light for my clone tent, so I’m kinda out of the loop. The boards have 301s in them too.

The ones I built from f series strips are on the ends, close to the sides of the tent. This light is more than enough for a 3x3 tent and with all 3 my utility bills are reasonable and yields decent so I’m happy.
