Drivers and heatsinks inside europe

[Alex77145]

I was wondering, where is the best place to order COB equipment that ship from inside of europe?

 

[Goerilla]

TMC.eu is the best for me.
But 1212 on Ebay.

1212 version 6, no freight and no tax for us in the EU.

I'm having hard time finding the info that I need. Anyway, what would be the overall best K? 3000, 3500, 4000? I am planing on growing autoflowers, if that changes anything. Also, what about the CRI?

 

[Goerilla]

I can not really help you. I have chosen 3500 90 cri based on what I found on this site.
Mostly the tread comparing 80 to 90 cri Cititzen.
I haven´t had a grow with them yet.

The higher the CRI the more red that is in the light. The lower the K the more warm white the light will be, ideal for flowering. The higher the K, the more blue is introduced. If you want more of a full spectrum that you can use for flowering and veg, then go with a 3500k or 4000k.
I've got 3500k 90cri that I plan on using for veg and flower. Hope that helps.

What would be a good passive heatsink if I am going to be running 1212s 49 watts each?

You would be fine with 120mm pin fin heat sinks. That's really the smallest I would go. My CXM22's run fine at 50w each on those heat sinks.

So can I just order any 120mm heatsink from alibaba?

What about holders and reflectors? Which ones do you use? And where do you buy them from?

 

[Goerilla]

I got some holders from TMC, no reflectors.

Are we talking about the same TMC.eu ? I can't find heatsinks or holders there. Am I stupid?

 

[Goerilla]

I don´t know if you are stupid but if you find the holders when you look at the cobs.

Heat sinks are also there somewhere.

Can I annoy you for the last time please? Cab you help me find 5 heatsinks from there that I could use? I will be running them at 50w each

 

[Goerilla]

I don´t know about the size if you want to use passive cooling, I use Artic Alpine 64 which I get cheap in Denmark.
But here are heatsinks at TMC :http://www.tme.eu/en/katalog/radiators_100095/
