All the talking about this project gave me an itch to start. Discovered that I will need quite a bit more alu than expected, so frame which is also the heatsink will probably cost around R550 by the time I'm done.

 

Cost of 100w COBs: R120 x 4

Cost of 50 12v COBs: R45 x 6

Cost of frame: R550

Cost of 12v fans: R40 x 2

 

Will post pics as I make progress, but light will be finished and hanging over the weekend.

 

Frame size is 600mm x 300mm

 

12v fans wil be connected for active cooling. As always, input is welcomed.

These prices are pretty good compared to what i've seen and you say they already have on-board drivers?

no shipping fees? 

Please share the link where you order. i take it they also got the smaller SMD's, 5050 or 2835 or 3528? These would require drivers however, but you can build such cool boards.

Im eager to see that heat sink work, as mentioned, that is were i still need to read up on and get a better understanding of how to calculate the size.

Will be following this closely.

Here we go, cobs in place, but still needs to be mounted. Had to dismantle my first prototype, using the COBs on this newly made cooler.

Wattage upped to 750w with the addition of 220v 50w cob.

Breakdown as folkows:
4 x 100w 220v
5 x 50w 12v
2 x 50w 220v

Ive left enough space between the back fins to add more if needed, but hopefully the current fins will be enough.

That's it for the morning, will probably finish it off this evening. 081e2d18acca7c29f1f6573393e61676.jpg

Extremely happy with the outcome. Total cost was perhaps closer to R1100 than the original estimate, but size is perfect for my 1200 x 700 veg tent. Frame Temps relatively low, running 4 x fans (2 x 12v & 2 x 220v).

Definately not my last build...
@Totemic, I'll let your Chocolopes be have the final say on light quality :) a473b74fcd5419b63279aeb26ba194e1.jpgae3df8bf90a9b2b544802241bcc0c9e0.jpg

[mention=1249]Trailblazer420[/mention]  what temps are you getting in you grow area with those lights? And what size is you grow space. I've noticed with led light I have to use so something extra to get the temps up.
25mins after watering and here it is... fbb968ec47735ba355f111514864d5f4.jpg
