I manged to get a frame built! I needed easy as I'm not too handy, but hoped for something fairly sturdy with an open center so I could use an AgroMax Pure UV bulb from tent top center.

Along with bulk chain, screws, a little vise (that I returned) and hacksaw, I grabbed this:

1ea 8ft aluminium tube cut into four 24" pieces:

4ea 3ft 3/4" aluminium angle cut to 30":

Not too shabby, it's a 30" x 24" to hold two 225w 3 light kits :)

What size are the heatsinks in the 200w kit? I compared them to my 120mm and they are a lot smaller. Then checked GN and his 100mm say 25-35w

The ones in the kits are 70mm tall so 73W at 80% is still only cooling 14.6w ???The 3590 run at 1.4 amp needs 23w cooling??
I run mine at 1 amp most of the time so only need 14.8w but no wonder they get so warm when I blast them.

Not sure what you all mean, the 200w kit is 4x 50w cobs isn't it? The 70mm high coolalliance offers 61-73w of power dissipation. Why wouldn't that be good enough for 50w of power?

i honestly dont know. im just asking. id like to know if there is any reason to go bigger?
Hi,

I wanted to answer the questions about the heat sink size and why we selected the ones we did for our kits.

The kits that are 50 Watts per COB use the Cooliance CPL10070 model heat sink which is 100 mm in diameter and 70 mm tall. The kits which are 75 watts per COB use the CPL14070 model heat sink which is 140 mm in diameter and 70 mm tall.

Here is the datasheet for the Cooliance pin cushion heat sinks:

http://www.cooliance.com/NA/Products/LED-Coolers/Generic/LED-Coolers-For-Other-Arrays.php

As you can see the heat sinks we selected fall well within the operating specifications. We worked extensively with the Cooliance engineering staff to select and custom machine the appropriate heat sinks for each kit.

These heat sinks will be warm to the touch - surface temps can hit 120°F and the pins register around 90°F at 50 Watts with a basic temperature gun.

If there are any additional questions about the components we use I would be happy to answer them.

Regards,
Dan

Thanks a lot dan! Sorry to stir stuff up here. Your reply answered the question perfectly and hopefully eased the concern of others.

120F?...so at 50w the cooliance 10070 is only running Tc=49c* and the pins =32c??
Is that your final answer?
seems accurate with my experience with the kits. hot to the touch if there's zero airflow but not painful hot and even a slight breeze and they're cool.
