In short, none of those are good options..

I could be wrong, but I don't think that aluminum disperses enough heat to run those at 1400 or 2100 mah.. You need the large pin heat sinks I believe..

The vero 29's run at 1400 mah are pretty damn bright and throw a lot of heat when run full force. I can't even imagine them at 2100.

The reason this kit is cheap is because they aren't giving you the proper heatsinks.

This is the way to go if this is the road you are headed down.

I have this light. It does a great job in a 2x2 space. It's actually more PAR than you need in that size space. Could probably light a 3x2 with it, but honestly for 3x2 I'd rather have 3 Cobs for better spread.

To get to 200 watts you need to just unplug the pedometer. They get pretty warm at that intensity though.

My space is only a 2.5x2.5, max 3 plants though.

Yea The Timber light that I linked to would be a good choice...

While yes you are correct you would need the pin heatsinks, RapidLED will switch those for you if asked. I just had them build me a 4 x kit of vero 29 C's for 400$ shipped to Canada

I would think you are wrong. Actively cooled vs passively cooled.... I think that having active cooling will allow the heatsink to cool just fine. I use pin heatsinks but wouldn't hesitate to use the one in those kits either.

Oh I didn't know it had active cooling... Should work then..

The only problem that I've read with active cooling is that if your fans drop out on you then your cobs melt. Passive sure is expensive though.

if vero runs at 1400ma, and the driver is 3000ma, 40volts, what happens? it melts down?

So, If the vero is 1400ma, but the driver is 900ma, 40 volts, nothing, but light works more efficiently?

No.

Went with the fixture from PAR-HORTA.COM, very happy with it so far about 2 weeks into flowering.
