grow led diy
Irukandji:
Hi guys,
i'm new to the Led subject and i have some questions about my Project. I want to build my own diy grow lamp.
My Problem is that i'm not sure if the calculation is wrong or not. My other question is are there some alternatives instead of my choosen led's.
LED from China all in all $18 for the LED`S for 60 LED's.
Here is the link of the LED's : https://de.aliexpress.com/item/10-st-ck-UMAKED-High-Power-1-Watt-3-Watt-LED-Chips-Lampe-Licht-SMD-Warm/32847256118.html?spm=a2g0x.search0104.3.43.48e34ec4bEGrJX&transAbTest=ae803_3&ws_ab_test=searchweb0_0%2Csearchweb201602_9_10065_10068_10547_319_317_10548_10696_10084_453_10083_454_10618_10304_10307_10820_10821_537_10302_536_10902_10843_10059_10884_10887_321_322_10103%2Csearchweb201603_59%2CppcSwitch_0&algo_pvid=f5cff3e2-8f46-41ac-ae2b-e1457b82ac3b&algo_expid=f5cff3e2-8f46-41ac-ae2b-e1457b82ac3b-6
6x 1w blue led (15-25lm) (300mA-350mA) (3,0V -3,2V)
18x 1w red led (40-50lm) (300mA-350mA) (3,0V -3,2V)
If you know some LED alternatives within the pricerange of 20$ for all LED's:
Blue needs to be 450nm
and Red 650nm
This Driver i would buy:
MW LPV-35-24 ... LED-Driver, 36 W, 24 V DC, 1500 mA.
So the Resistor should be around 50 Ohm.
I would choose a parallel circuit with a Series circuit.
The Example belove.
If you have some better opinions about a diy grow led please let it me know.
Thanks for your help.

Beware of Chinese Watts. >:D If the LEDs are fine then I'd order a few more as spares. Also I recommend to run the LEDs at a lower current (70-80%) than rated and to provide sufficient cooling (large heatsink). This way you'll get a LED light with a reasonable lifespan. I've built a few myself, e.g. for a fish tank.
Irukandji:
Thanks for your reply :),
whats about the lumen output of the Led? Is it a lie or close to the specification of the lumen output? You know some alternative Led's?
What about the Driver should i buy some other? I will order atleast 40 red and 20 blue.
Which Driver would u prefer for the 3W Led's same Setup?
madires:
Same as Chinese Watts. ;) The only way to be sure is to measure the lumens. I can't recommend any specific no-name LED because you get the cheapest available in Shenzhen. No, a MEAN WELL driver is a good choice.

I like to make a grow LED also, for the PSU i would shenzen not for the LEDS.
I have this galvanic wire for the LEDS.
And i will buy Cree LEDS only.
I dont think Cree have diffuse LEDS, i dont know if its needed or not ?
For the power i will use switching for each LED plane, so can have many LEDS from the same power, i dont know if its good or not to grow.
Now i go smoke thanks to you.
