I don't know what my fiance did with my camera or I'd take pics. I bought a pack of S hooks to replace the carabiner. Basically I just used 1 S hook per side and attached the 2 cables from each side onto the bottom of the S hook. The top of the S hook hooked onto decorative chain hanging from the ceiling.
This prevents the twisting from the 1 point hanging system, but it's still not especially attractive, and height adjust, while possible, is a little clunky. I'm going to upgrade it to a Griplock hanging system before too long.

Yes you might start with #220 but by the time your system is built up you will be way higher.
PWM Controler $219
6 Expansion modules to operate 64 LED's individualy on three sepearte color levels. @ $89 each = $534
That totals up to $753 Then the controler only has 64K of EPROM memory and by the time you finish up writing a program for it you will be needing at least a meg of memory for a three color display.
Next you need 8 driver for each color for a total of 24 drivers eaxh capable which your be in the $35 price rang so it vcould add another $840.00 And finaly your LED's where your talking three color LED's at 3 Watts per color so you probably going to drop close to $15.00 thimes 64 LED's another $960.
So fat that brings you up to $2,800 with out calculating the amount of time it will take you to program something like this and build it up. And yet I see a big bug in it for starters being increasing the memory.

One of these pumping out 120 Watts of light efeciently should be more than enough light. After reading through there listed literature I will say I do like the idea of using 12,000 to 14,000K white LED's. I personaly use neutral whites that are closer to 5,000K in a ratio of 4 Blues to 1 white or more.
Keep in mind that some low quality LED's are oput there producing 120 LUMs at 3 Watts and then are the higher quality ones now exceeding 300 Lums at 3 Watts. They are not disclosing what LED's they are using. Keep in mind that $160 for 55 LEDs averages $2.90 per LED much less than anyone could purchase just the LED's for.

-Then we have to stop posting to keep prices down 
I experienced the same with a local dealer of chinese led fixtures , in two month's time the price went up from 259 € to a blistering 400 € for a dimmable 60w xp-g fixture :eek2: :uzi:.
Luckly i had mine at 259 € ( +/-300 $)

It is called supply and demand. When I had my pet store another general merchandice store lowered there Aquarium supplies so they were under my wholesale cost. When I cosed my doors it took them roughly a month and every one of there prices were considerably more than what I would had charged. They were the only ones in the ball park so they could charge what they wanted to cherge and there customers were simply in buy it or don;t buy it situation unless they wanted to travel 30 miles to the next closest aquarium store.

Ive run the 1 wt leds on ebay for a yr in the 120 wt and 200 wt fixtures and I did like them. Have replaced most of them with the 3 wt crees which are doing even better. Started by buying 9 of the 60 wt, have now bought another 6 of the 144 wt. My corals for the most part are loving them. My dislike is the controllers an now only buying ones without controllers, there also much cheaper, 1 Ive had trouble with controllers which they did replace on 4 60s. 2nd When the electicity gos out I have to reset the controllers, just tooo much trouble, Still looking to buy more as I can afford them. Running 2400 gals of reef tanks is why I need so many. There now coming out with a 188 wt cree

Thanks for the tip on the fans cbm369.
I wanted to post a pic of my blue monti - first pic was taken on 3-4, you can see the growth edge is white, and the tips of growth were white also.
Second pic was this weekend. The polyps are much lighter in color, and pretty much all of the monti is a nice baby blue. So as far as colors go, I am confident these cheap LEDs can do the job. This monti is on the sand bed. Unfortunately because of the blue LED lighting, and the learning curve on taking pics in that lighting the thing actually looks much bluer than it was...

Could be either, but it's not uncommon for fans to be temp-controlled. No point in running them over a cool chip.

-The 48 X 3 W G4 eshine fixture i have with sunrise controller even let you see how warm they are , the fans running very very quit , i never had hoped for such noise - free fans , only the driver fan you can hear .
-The older fixture over my nano (60 w) has a very big heatsinck and when the fan goes on (only 3 times a day for 5 minutes) , it produces alot more noise.
You realy see these chinese fixtures progressing in quality :thumbsup:

Well my fans were indeed malfunctioning on one of my 2 units. My fans haven't worked all day. There is a small black box within the fixture that controls the 3 PC chassis fans. Figuring that was the cause of the issue, I connected the fan controller from the working fixture to the malfunctioning fixture and the fans spun right up.
I contacted the ebay seller to see if I could get some parts under the 3 year warranty. I really don't want to have to ship the whole fixture.

No doubt. They are simply using cheap PC fans anyway. Replacing the controller + fan should be easy. To be honest you might not even need it. These boxes run super cool if mounted out in the open.
