I bought mine from mouser.com. They should ship to all of Europe. It was their Swedish division that billed my order, but they sent them from the US.

Did you have to pay any taxes that where not billed by mouser or deal with customs?

Digikey.com is another option, free shipping from EUR 65 on as well.

For parts sourcing check octapart.com

I only had to pay the IVA, where I am from you have to pay IVA if the value is above 25usd. And the only way to get around it is to buy from China, they always say value is 10 usd. Ups sent me an invoice a few days after they arrived. shipping was 5 Usd if I remember correctly. The leds arrived in 4 days

Well...It took a long while, but 35 cxa3070's are running @1500mA (forgot the exact amps) with active cooling and have 5 cobs left. Each string has 315 watts without the fans. Every fan has its own power source of 12 volts, and the fans together it makes a hell of a noice. Going to remove the individual power sources and going to use one power source per 5 fans. My goal is to run them on 8 or 9 volts because it will be a lot quieter. After this run I am also going to adjust the wiring so it will be a lot safer to work around it.

Total 2205 watts of 3070-power on about 3 square meters, 40x 11 liters.

Plants came in two batches because I had to much lights and to few plants so I planted some more after a few weeks.

Nice happy! Forgot you had a big build going.

Those are the nuventix coolers? Do they stay cool?

Hope everything works well for you :clap:

They are cooler and fan from Mechatronix. They can cool up to 20.000 lumens and 200 watts dissipation. They stay very cool. I have also some other herbs that never grew outside in the sun but under this light it grows and grows. We will see in a few weeks how its going.

Forgot to mention, I was unable to use the big capacitors to repair the power factor of my LED drivers (800mA drivers from perfectdeal_us). The capacitors are able to realign current and voltage waveform but in my case the low power factor is caused by harmonic distortion of the current waveform. No biggy though, can resell the caps or use them for some other project. I don't mind having a poor power because the current draw is only about 9 amps per circuit, but it would be nice to have it corrected so it would be greener/cleaner and more easily run off the grid someday.

Most recent batch finished on time (7.5-8.5 weeks) Just finished trimming them and there were some new flavors to test out.
Cali Connection - Purple Chem #2 - raunchy meat fuel - nice nugs
Cali Connection - Purple Chem #4 - chemmy meat fuel - nice nugs
Rare Dankness - Scott's OG - great yield and great nugs, no larf - no hermy
Rare Dankness - Lee Roy OG - Top Notch flavor, yield and great nugs - no hermy
G13 labs - Pineapple Express #2 - awesome nugs but nothing extraordinary about it
Dinafem - Dinachem - strong flammable fruit smell - nice frosting - no hermy, not chemmy
Cali Connection - Green Crack - very fast finishing but low, plain aroma
HSO - Green Crack - awesome nugs but nothing extraordinary about it
HSO - Purple Train Wreck - very flavorful and frosty but very larfy - will try this one again though
HSO - Lost Coast OG - awesome nugs but nothing extraordinary about it - low odor
HSO - Desert Diesel - top notch flavor and great yield. does get a few early herm balls on lowest branches but no beans so maybe it is sterile

Overall looks like it will be a great harvest, numbers in a week. Once they were finished I added a few more modules so tent2 is 660W dissipation and tent3 is 625W dissipation. The real standout for this batch was Lee Roy OG. Similar flavor to the Kandy Kush that I love so much and the Desert Diesel. From a few dozen OGs I have tried so far these have best flavor in my opinion but hard to describe. Very strong flammable OG perfume, both sweet and spicy. The Purple Chem gets second place and is the only variety I have come across so far that has the Chem flavor, disgusting in a good way lol.
