Chinese 10W LED vs Chinese 5050SMD's.




Figured u guys might want to see how awesome the 10W's are..

The 10W LED 6000-7000K "Cool White": Ignore my wiring.... these are purely for testing only.. so i didnt solder it.


They get HOT... way hotter then i imagined... They run at 12V, so u can use a cheap 12V psu to power it. Im using this guy at $15 with a 5Amp capacity:
http://www.svc.com/pa-ad-ul-12v5a.html


I first tried using a ram sink on them, and failed horribly... then tried to put them on a passive northbridge sink, and also failed.

Seems like i need to use at least a GPU cooler to get them to run cool.



It adds very nice shimmer...



What i was playing with b4 were 5050SMD's.
Im originally a PC modder so 5050smd's were toys to me in lighting accents.



Well 5050SMD's fail horribly...



So Cliff's

10W LED:


5050SMDs:


I have 2 more 10W's i plan to use on my 29 gal.

I also have a few 3W Cree's coming in soon, so i'll give u guys a comparison on cree's vs chinese 10W.

LOL my 10 gallon test tank... :\
It takes so much abuse.. but my little ram is such a fighter, he's very durable for a ram.. no kidding.

Did you consider using thsoe 10W LED flood lights?

What GPU cooler is that for? Looks even bigger than the one on my Phenom X6. I only used the stock one.

I have a 5x1W LED screw in bulb, the heatsink on it doens't seem adequate because i burned myself, I can only imagine how hot a 10W gets.

its the zalman one with heat pipes... i forget the model number.

Didnt want to use the flood lights because part of the fun for me in this is the actual building!

Currently im still playing around with them.. the LED's dont even require a solder because u can use 16-14AWG disconnect pairs to tie them.

Im also playing arround with PC fan controllers by sunbeam to use it as a dial so i can dim the LED's @ will.

LED's are so much fun.


But yeah.. i can totally see why people use 3W LED's instead of these 10W's.

They really burn HOT.

Nice comparison.

The big LEDs can really be useful as long as you don't mind the occasional shadow, or if you can find an optic that will allow you to raise it up high to make shadows smaller without losing intensity.

some updates... i decided to wire up the 2nd 10W LED.

My fish are thinking there are 2 suns....



This is how you can also wire these guys up without soldering...


Im using my own thermal adhesive :P basically add a tiny drop of super glue to your favorate thermal paste blob.



As you can see i tied them to a fan controller, so i can dim them via voltage.

Ummm should i toss the third 10W on the 10gal?
I think my fish would go blind then no? :P

Its pretty fun to play with.... now i need to wait for the cree's, but i figure 4 of them are required to = 12V and 12V in LED's should be more efficient then 10W single 12V led.

a 29 gallon which i took apart, and that i will rebuild once i get everything i need down.
Right that that 10 gallon is my Toy tank.. to see what works and what doesnt... a quick burn down lesson in a sense b4 i step up to a larger vol. tank.

lol... i am trying to get back into the game with the new tech, also meshing what i learned in PC moding to the actual fish tank.

Funny eh? :P

one expensive hobby to another at least its not cars again... :\

This is awesome!
Its also something I've been thinking of doing since i work at a pc repair/recycling place and have TONS of power adapters..

Can you explain how you wired in the fan controller to dim the LEDs?

Let me know if u dont know how to jump start an ATX PSU.
Its fairly easy by crossing the green wire with a black ground wire, and u can make that ATX PSU work via switch on the rear.


Basically a fan controller handles voltage. They are basically pots.. or rheostats which limit voltage.

You need to make sure first off the fan controller can supply the amps per channel. The Sunbeam is a great controller for the price.

Now a fan has 3 headers on it.
Black Red, and Yellow.

The black is the -, the red +, and the yellow is an RPM sense header.

You can buy fan headers at any PC accessory store, or fan header extenders and just splice the ends together.
http://www.jab-tech.com/12-3-pin-ext...2-pr-1614.html

Then plug the new fan header into the fan controller, and use it as a dial.

If you want pictures i can take some and show you.


Just note, if your going to use something higher then a 10W LED, like a 20W LED, it wont work unless its 12V.
PC's just happen to follow cars in the 12V rule, so PC accessories will work with 12V LED's.

Or you can just serial wireup 4 3W Led's so they = 12V, and control all 4 via 1 dial.

The sunbeam controller $14.00 :
http://www.jab-tech.com/Sunbeam-5-1-...K-pr-2530.html

Specifications

1. Power : 20 watt per channel
2. Input voltage : DC 12V
3. Output voltage: 0 ~ 12 V
4. Output current: up to 1.67 A
5. Dim: 148.5x 105x 42 mm
6. Weight( Net) : 184

Can handle up to 1.67A / channel, which means easily a 10W x 2 Led on 1 port as long as they dont draw more then 800mA each.

The ones im using can draw up to 1amp @ 12V ~ 12W LED and not really a 10W LED...

i should tie them to my multimeter and find out if the spec's are true or not :\

Updates:

3 x 10W LED's :O my fish are gonna need sun glasses


how its wired:


and all 3 dim'd.

Hurts my eyes just looking at the lights lol. LEDs are crazy bright. Awesome setup, though. Any thoughts on a shroud/fixture to contain the lights?

hoppy has a thread where he is using PVC as a support to hang the sink on top of the tank.

i think i am going to go though that route, with this sink supported by pvc....

so wait, are you using a psu AND that power adapter to power these or can you just use a standard psu? I know the fan controller takes a 12v standard molex connecter but you originally showed that power adapter.. If i can just use a atx psu to a fan controller and then the led's that makes it super easy.. Otherwise if you need both i'm slightly confused on the wiring..
