This seller is not the cheapest, however I have run 27 pcs 10 watt chip´s from him for one and a half year without any problems. I have also 20 watts and 100 watts Epistar-based chip´s that have run for shorter time (3 - 12 months) without any problems (from the same seller) I do not know the qualities from other seller´s - but I´m satisfied with the quality from this seller.
Sincerely Lasse
Thanks Tickle, mind if I ask where you got your chips from? How long have you've been running them for?
What heat sinks are y'all using? Right now I'm thinking what RTMA is using: Artic Cooling Alpine 64 PRO Rev.2
A single Kessil gooseneck can hold pretty good weight. I'll measure how much a single gooseneck can hold this weekend. At one point I measured how much but I dont remember at the moment. I'd guess about a pound but let me experiment and I'll report back in. There's nothing wrong with using two goosenecks but if it only takes one then why use two.
Depends on what your needs are. I prefer a little bit of margin and use the Arctic Cooling Accelero L2 plus VGA cooler rated for 120W for both the 50W and the 60W multichips. They can be had for $20 with free shipping on EBay.
Got the Arctic Cooling Accelero L2 Plus 120W VGA cooler attached to the Kessil Gooseneck. It turned out pretty good.

Im currently running a nova extreme pro. Half the lights are 10k bulbs and the other half actinic. I currently have the actinics on for 12 hours and the 10ks on for 8 hours.
I want to go slightly more blue so Im looking at the 16k chips.
I have a 125 with 3 equal partitions on the top of the tank. I was thinking of building 3 pendants, one over each section, with each pendant in a sort of star formation.
1 50W 16k chip in the middle(total of 3)
2 10W 445nm on opposite corners(total of 6)
2 10W 450nm on opposite corners(total of 6)
I was planning on running the blues 12 hours a day and the 16k 8 hours a day. Do you think this will give me a good color balance similar to what I run now only slightly more blue?
hi.. i'm reading from 1st page to 50 page and still confuse to choose what led should i build.
my tank was 100cm x 50cm x 50cm
what should i build ? are 1x20W 20K white and 1x20W blue ? or 2x20W 20K white and 2x20W blue ?
also please help me to choose the driver.
does anyone would help me please ?
You're still saving over $100!
Not to mention the flexibility in power for the DIY build:
DIY build power output: 93.6W-187W.
Kessil A350 power output: ~90W max.
...and the DIY build looks good too!
I have to say though that I really would have expected a much larger savings, I mean compared to something like the smaller 3W led fixtures where you really have a major savings in price, take something like the AI Sol unit, someplace like RapidLED has a kit that even has the 3LED pucks just like the unit for about half the price. (nearly $200 savings).
I wonder what the actual light output of these overseas units vs something like a Kessil is too.
This is a verry nice thread with lots of information.
I have a tank with this dimentions: 200 x 70 x 70 cm with 2 dividers.
Now, I have 4 x 250w mh 14.000k and I want to replace this with leds.
Witch leds do I need?
Is it enough to have 3 x 50w like this: http://www.ebay.com/itm/New-40mil-5...800?pt=LH_DefaultDomain_0&hash=item33779e0520
And some other chips of 20w 20000k?
Maybe its better to use leds of 100w?
Thanks for the help and information!
