NOTE: If you have any questions about GU10 bulbs. please post them here in this thread rather than PMing me personally. It would be better for the whole community to benefit from your questions. So dont be shy and ask away. If i am not available to answer the question someone else will probably answer just as quick.




Okay I've had a bunch of people ask for a thread on the LED that i use for my tank

here is a quick video of the lighting all setup




The build is really easy.. Get the bulbs and wire them parallel
(here is a link to a quick picture tutorial i did recently http://www.nhfragswa...msg2572#msg2572 )

To find the Blues search ebay for 3w gu10 blue
http://www.ebay.com/...1...ue&_sacat=0

to find the whites search ebay for 3wgu10 cool white (whites 6500-700k (nice bright white))
http://www.ebay.com/...1...e&_osacat=0


luckzdl2008 is my favorite ebay seller. If he doesnt have any listed just message him and he can usually put some up for sale in his ebay store . Or just sell directly.

Sockets: This dealer is in NY. sockets arrive very quickly. The link is for the search in the dealers items. so you will be able to find them from the right dealer with one click. $10.29 for 10 sockets
http://shop.ebay.com...1.c0.m270.l1313


or search ebay for g10 base socket
http://www.ebay.com/...s...s&_osacat=0








i would say don't pay over 7.50 per bulb if the dealers i mentioned are out of stock or not selling. You might be able to find a dealer with a best offer situation.. i scored a few for $4.50ea on my last order.



I have had a lot of people ask how many to use..


I have a simple formula

(tank length divided by two) minus 1

so for a 36" tank you should have 17 bulbs. in a single line.. alternating colors.

for tanks that are deeper than the standard 12" add another row.

so a 36x18 foot print should have two rows of 17 bulbs.










I will attach a picture of what the bulbs and sockets look like.

There are two different bulb arrangements.. Three 1w bulbs or One 3w bulb. either is fine. I have a mix of them. I do find that the One 3w bulb version seems to have a better spread on the light.

here are a couple quick wire diagrams. the cicles represent the sockets. the bulbs have reverse polarity protect on them. so you don't have to worry when you put the bulbs in the socket if they are in the right way.

Growth. The Proof is in the real life results. (i am not the only one with the same results using these lights)

I have some really encouraging pictures to show. Mind you these are 4$ ebay LED bulbs. not expensive cree bulbs. they shoot 1500-1900 par at the surface!

here is a picture from March 20th 2011)

even more encouraging is the growth of my crocea clam. I brought this home Valentines day 2011

march 20th 2011 .. serious growth

UPDATE:
Now march 2011-jan 2012

I love tracking the growth on these. continually impressed.




par readings in a 5.5g


i had 5 bright white and 2 blues

3" from the bulb (above surface of water) 1900 par

just below surface 700 par

halfway 200 par

1" from sand 150 par

NOTE*
for those wanting to remove the optics for tiny shallow tanks use this to adhere the led chip to the heatsink:

Adding a quick wire tutorial

I started wiring them a little different. Makes it so you dont need to use any wire.. just wire them piggyback to create a parallel circuit. Way easier.

Anywho here is how i attach the wires. Most of the fixture pictured here was shrink wrapped but i ran out when i was doing the pics

divide the end into two sides
wire5.jpg

then put the wire you are attaching to in the middle of the split and twist the two ends so it secures the wire between the other wire
wire4.jpg

then wrap the tail around the wire
wire2.jpg

Then tape or skrink or sometimes i will actually silicone over the connections to make them water proof

these suckers really shouldnt be over looked. the price is awesome and the results are even more awesome!

no power supply needed.

you just wire the sockets right to a plug.

thats the beauty of these and the reason i didnt bother with the cree stuff. I didnt want to have another room with 50 million drivers . these are complete and plug and play. just make sure you run them open air. they use the metal housing as the heat sink.

the 6500-7000k isn't yellow at all. It's perfect with the blues added to it. I don't think the cree are even 10k I was able to borrow the par meter back in april but haven't had access to it since. That croacea clam grew 1/4in in a month.. That's proof enough for me lol.

yeah most of the whites i have are the 3x1w

all of them are mixed between 1x3w and 3x1w they are all the same brightness and color.

just make sure the listing says 6500-7000k or cool white.. the 3500k warm whites are really yellowish.

some of the guys in my new hampshire group put a mix of a few 3500k in there for good measure and better macro algae growth.. but my algaes and corals have been growing really fast on the mix of the whites and blues :)

i just went with what ever i could find cheaper.. didnt care between 1x3w or 3x1w
