diycob

So I have a great cob setup its a tasty 300w 6 cob design. It works great in a 4x4 but it really rocks a 2x4 which I use for flowering. My question is to all the cob geniuses on here can I upgrade the cob chips to say Citizen, luminous etc... I'm just curious. I am however thinking of swapping...

I would like to build a 400watt cob or quantum with a dimmer for my tent— Can someone be so kind as to point me In the direction of a parts list??? I’m lost looking at these forums thank you for an help.
