modular overkill led striplight build

nice, finally someone else embracing the idea of throwing in a shitload of low run strips

Ive done 2400 samsung diodes per meter bu this is 3808 diodes, next level. And if you count pper actual size its even more, fixture is .8 by .8m.

really a lot leds, haha, so many that the few reds i will add almost dont count.
Was too lazy today for solderingm hopefully sunday ill find the power.

i fear i can not edit the placeholder posts.
So here are the datasheets of the used Leds, just to have all at hand.

managed to finish some color strips today.
First the 660nm, thermal managment is looking promissing.
Driven with 300mA we have just 40c,



driven with 400mA (max i would use anyway) were at 46c.



Took me 4 designs to get there but am surprised what cheap FR4 can do if you use it right.



The PPF/W (PPF/J) ratio is also quite nice.

Cant wait to have all complete

Hey cob shop. Any chance you could say what reds you got?

Also i might be in the market for a flir thermometer, whats yours like and how many €¥$?

sure, datasheet is posted above, prolight opto crimson

mine is a seek xr, prefer it over most comparable flir as the min focus is closer.

more n more strips finished.
Some UVA, some far red, quite some 660nm on extra channels.
The extra strips are made to went in between the bridgelux strips, snug fit, just need some finishing.
Scratching my head about the final arrangement of the extra color srips.
Pretty modular stuff.

Damn let's see this I'm action!

working on it, cant wait too, but regular work kept me busy.

"Overkill" is subjective ....... I also would like to see this in action.

Always subjective hehe, at least tons of strips used here.

omg friday allready, think on weekend it will see its first action.

So here it is in action.
3000k 80CRI, 660nm, 730nm, 365nm.

the 730nm and 365 are not really within our visual range, so they appear very dim.



only 660nm on

The 3000k main light as the 660nm strips are pwm dimmable.

I used one 8w meanwell for the 365nm leds a 6w meanwell for the 730nm and a HLG-40-48A/B for the 660nm.

Thats it so far.

How many of reds, far reds etc and what current etc are you aiming for?

48 x 660nm, 12 x 730nm, 12 x 365nm.

660nm:
HLG-40-48V, set to about 52V, makes 40W at the wall.
I aim to keep them under 400mA each led, will drive em with about 300mA in the all in all 30W region.
Aim for about 10% of the main light, if you convert ppfd 1:1 which dont work, but anyway, roughly.

730nm:
is driven by a 12V 500mA, makes 250mA each led.

365nm:
is driven by a 8w 24V CC 350mA driver, makes 175 each led, the low nm uv shouldnt be driven that hard.

for the ones in the usa looking for t-slot profile, one source i have found.
8020.net
while there are maybe cheaper sources, i payed less for it.

Beautiful rig!

having my channles now on some wlan smart plugs with all bell n whistles, timer (of course) and also wattage.
Nice stuff!
main 3000k, red 660nm, far red 730nm and UVA 365nm

have to say really loving these gosund smart plugs.
Setup was easy and so far they work very reliable.
Main reason to buy these was that i needed a more precise timer for the far red, but am impressed what you all get for these few bucks.

hardly can be smaller.
Theyre avaiable for all countries, can just recommend!

a little update.
i put some critical 2.0 under the lights, just using the 3000k 80cri channel so far, wanna veg them a bit more.
as always it takes me a bit time till i have it dialed in with a new setup.
the plants where not able to take 80w (wall), the light is about 30cm away from the tops.

i dimmed the light down to 48w and theyre going better now 48h later.
Hope to be able to give them some stronger light soon.



CO2 Temp RH level is ok, me think.
