Testing out some 10W Chinese LEDS
 
I've been testing out 4 10W LEDS while dry starting my 55 gal planted tank. They seem to be doing great. I build a fixture out of an old aluminum tonneau cover frame. It's extruded aluminum, so I just chopped it down to size and bolted it back together. The bow supports that ran accross the bed are what I mounted the LEDS to.

that looks pretty bright, considering the depth of a 55g. how much did you end up paying for the four modules, if you don't mind my asking?

No idea which ones he has but 10w chinese modules are like $6 shipped from dealextreme.. Of course, XML's are $6.80 each from ledgroupbuy, and put out at least as much light, although drivers are hard to find.

I'm curious about 2 things, are those 6500k? And, are these the square emitters, or the round ones? It looks like if you ever need more light, all you'll have to do is put reflectors on.

which ones did u get?

the circle or the square?

i have made this bold statement many times on this forum..

when it comes to LED's i dont think anything beats the chinese 10W in our DIY's

Ive been getting excellent growths off them.

blackdog76 01-22-2012 02:48 AM

they are square, 10,000K

were around 7.99 shipped each, and each one has a driver that was around $5 each

Can you post a link to the ones you bought?

Brian10962001 01-25-2012 05:40 PM

Yes, links or PN's please. So no optics, you just let the LEDs shine?

Never seen optics for 10W LEDS, this site wont let me post ebay links

I actually have the 65ook round ones from deal extreme. They work pretty good and have some nice growth under them. I will be adding a third one over my 29g tank, even though I do pretty well with just 2, I think it could use more light.

This is the one- http://www.dealextreme.com/p/10w-led...ite-6500k-5876

Along with a 4"x4" extruded aluminum heatsink from - http://www.heatsinkusa.com/

Although, you could get one from deal extreme, I have only seen round ones. I like the squareness of the extruded ones due to ease in mounting them.

you can post the auction id though. so you used a driver per led? can we see the wiring?

AC goes to the two wires of the same color, on the left. The tilde indicates AC.
The wires on the right side are + and -.
Those go to the + side of the LED and the - side of the LED.
We're fortunate that the wire color is actually correct.

Of course, I've had prior experience guessing.
I got a bag of drivers with pink, brown, and white leads once. That was interesting.

it'll take a 100-240volts ac?

meaning i could literally plug one right into a socket?

each 10w LED requires a driver, how would one wire multiples to a single receptacle?

blackdog76 01-27-2012 03:10 AM

Yes, one driver per LED. Kind of a pain in the ass and a lot of wiring but I wired it all into one heavy gauge power cord.

lolz...

ummm just to let u guys know those drivers handle 1 LED.

If you guys are going to do a chain of 2 or more, you can get a more reliable meanwell, and set the driving current to 900mA.

I have 4 tied to a ELN-60-48P, the next thing i want to do is tie that on a dusk / dawn controller next.

Second thing i should note.. the circles have a smaller firing arc vs the squares... the lights intensity from the circle is a bit more focused because of the smaller arc.

Other then that, they are all great LED's.... as i said ive been playing with them for a while, and they are far better then any cree's ive played with with the exception of the XP-L @ 3Amps.

fishykid1 01-31-2012 02:10 PM

Did you really just say they're better than Cree? I would like to inform you that the Cree LED's are also only 3W LED's compared to the 10W. Also, they are XM-L not XP-L.

Other than that, this looks promising as long as they hold up...
