That's pretty standard.

Hi everyone.

I have been building my custom lights for almost a year, no where near to be finished.
Friend of my got 3 light from eBay, it's a D120 knock of. My first impression was great so my wife kinda pressured me to buy some instead wait who knows how long to finish my RapidLED custom lights.
I got this http://bit.ly/15FMiRY from eBay.
Have to tel you guys that this is far more superior that what my friend got.
The LEDs brighter, more complex spectrum like 420,450,490 blue LEDs mixed instead of just blue.
The LEDs actually have heat-sink on them.
All 3 fan runs regardless of one or two led strip powered up.
Nice fully linear dimming, compare to what my buddy got.
I take it a part almost immediately, this led drivers are digital, the internal connector have PWM input, there is PIC12F683 microchip taking care of dimming instead of analogue dimming.
The outer casing powder coated instead of mat spray paint.
If you buying one from eBay I strongly recommend this one.

I believe the LEDs in your Rapid kit are Crees? They tend to be more efficient than the average Bridgelux emitter, but this fixture seems to have enough wattage to do the trick. Is there an outside RJ-45 style connector on the fixture?

Yes they are Cree XML and XPR LEDs, the controller I build for the first prototype is working but didn't finished other interface needed to communicate with the led module.

This eBay light I'm referring to looks great, works great and was half as much what I paid for the RPDLed kit including the extra drivers, plugs, internal connectors I bought for it afterwards.

The modules don't have external PWM input but the 2 internal driver has it, should be easy to install a simple plug for it. Already thinking to install a PIC micro and connect it with NRF2401 radio to external controller. Will see, for now I'm just happy to have this and not one of the knockoff.

You using an Apex or Digital Aquatics? If its the DA you'll need their controller module. I still like the Crees but have both and both grow coral just fine .

You better make sure you like the full spectrum color before you buy them. I'm definitely not a fan of the reds and violets being in a fixture.

I am, but we argue about it all the time. The coral doesn't care, it's a matter of preference.

Corals will grow under the blue/white LEDs. But how are the coral colors looking? Do reds stay red? Added colors from the full spectrum units should cause better coloration in corals.
