Looking for heatsinks

[sphelps]

Anyone looking for the square tubing for heat sinks can get it at Metal Supermarkets, the location in Calgary has plenty of 1.25x1.25x0.125 6061 in stock. Cost me $80 for 16 feet.

is that what your using for yours?

I have seen 90 degree ends that that size of tubing can slide into.. just have to remember where, as that would mean you could do several runs with one good fan.

Yes I'm taking this approach, I considered running a single fan but in the end I decided just to run 4 separate tubes each driven by a single fan.

I thought about this way also. separate fans will use a bit more power but the heat removal will be more efficient as in a long aray driven by a single fan the air temp would be more by the end.

which fans are you using?

I ordered the Pressurizing Cooling Fans from Steve's LEDs. I also ordered most of the LEDs for my build and drivers from him.

cool, I have been thinking of using his for a test build, but let me know what you think of his stuff. to bad you didn't have a PAR meter or live closer.. I would like to see how the edison LEDs preform compared to the Cree. I think my only problem with Steve's LEDs is he has no nutral white.

Will do, one of these days I'll update my build thread on some of my progress.

I just went with his 10K and blue leds, 56 of each. I then ordered some red and yellow LEDs from another supplier so I should be able to get the color and effect I'm looking for. I went with Steve's LEDs mostly because he seemed to have the best balance for performance and price plus his LEDs have a 90 degree spread so I won't need any optics which I prefer. The crees are nice but for the price I think these will be more than adequate for what I need.
I'll also be using the profilux PWM LED control 4 to control everything so I guess we'll see how that works out.

I dont have any cree running at the time (have 100 ready to build) but now have one pendant with the S. LED's and I findthy are doing gust fine.


I have them (28) on 2 heat sinks with the 60 degree lenses on them above a part of my 30 inch deep rank.

it is gust that with a Group buy the Cree where cheap so I both about 100, but with the steve once I think you get a fair bit.

I have green zoa's on the gravle that are doing gust fine, and about at 18 to 20 inches deep a nice birds nest that has growe from a tiny 1/4 inch tip to a 7 inch nest in a year.

from the 18 to 20 inch depth upwards there are some more SPS as well as a clamp, and some LPS. so far it is running for a year and I cant se any diferant in growth ore color of the coral when compairing with the 250w phounix builbs (exept the spread, as everyone knows the LED's are more concentrated.

when I build my steve LED poendant, I got a hell of a service, and cant compliment him more for that, he realy want you to have it working well.

in the upcomming weeks I will put cree's next to the steve led's (same amount of led's per pendant, and would be nice to se the diferant, if it is extream, I might need to put the steve led's above my frag tank
