Chinese LED Lights

So after reading pages and pages of this thread and the previously closed thread, I took the plunge and ordered myself the standard d120 unit. At first I thought, "Oh, I can plan my own LEDs and order exactly what I want." Then I quickly realized, even after reading pages and pages, I have no idea what I am talking about in the least, and so I went with the standard unit.

My question is, while I anxiously await my lights arrival, what does it mean to dial lights up and down? Is that like the intensity for each channel? Also, is this what is used to acclimate the corals to new lights? I have LEDs on my tank now, but they are only blue and white. I'm sorry if these questions sounds really dumb, I just obviously have no idea what they are. Thanks in advance.

Your light will have 2 dimmer switches on it, one for the mostly blue channel and one for the mostly white channel. You can control how bright each channel is by 'dialing up' or 'dialing down' the dimmer. The best thing to do is get a PAR meter and test how bright your current lights are and start your new one at about the same brightness. But PAR meters are expensive, so maybe you can find somebody in your local club who has one you can borrow or rent.
 
Thanks for that. I guess by some sort of divine intervention, my transaction didn't go through. I just read up a bit on the photon lights by reef breeders and am probably going to go with those instead. Now, I just need to figure out which ones...
 
Channel 1：35K-10pcs, 65K-12pcs, 10K-12pcs, 450-6pcs, 460-4pcs, 520-2pcs, 630-1pcs, 660-1 .
Channel 2：450-22pcs, 440-12pcs, 460-10pcs, 400-2pcs, 420-2pcs.
Channel 3: 450nm-3

anyone get this layout yet.. looking for feed back.. thinking im about to place order

I think you'll be happy with the upgrade to the Photon/IT series. There are a number of small advantages over the 'Value Fixture'/D120 lights. :thumbsup:
 
I have two 2080 that I have had for about a month and I have had three LEDs stop working. Is there somewhere in the states I send them in for repair.

If you go back to pg100 you'll see the layout on the fixture I bought, it looks similar. This was done in a group buy here in Portland Or and the supplier here will be using this layout I believe.

I did replace the 35's on the ends with 10k, it looked a little yellow and dim at the ends. When I lined them up together I left the 35's on the end of one fixture so it still follows the original pattern.

There is a comment/reply from Reefbreeders on the light layout also, I did not change any other bulbs once they were up and programed, I like the look so far, there is a picture on pg99

It looks like the evergrow light only uses 2W bulbs vs the the 3w bulbs in the Reefbreeders photons series. Also the photons have a digital ramp up/down controller built right in.

Are there any other major differences here.
Is reefbreeders considered Chinese? They say they have a 2yr USA warranty

I believe most of the Chinese manufacturers use 3 watt bulbs, but run them at 2 watts of power in order to prolong the life of the LED (it's not uncommon to see that).

The Reef Breeders Value Fixture and Photon series are both made by EverGrow in China. EverGrow calls them a D120 and IT2040, IT2060 and IT2080. Other than color layout, they are identical. They both use 3w Bridgelux leds. They aren't as strong as Crees, but they work just fine. They both under drive the 3w leds so they run cooler and last longer. I got better PAR from all my EG fixtures (3 different models) than I did from my Eco Tech Radion (which I sold). Reef Breeders is comfortable enough with EverGrows quality that they offer a 2 year warranty. EverGrow fixtures come without any label and logo so any distributors can re-brand them. I've had mine for 3 months now and they all work perfectly.

What do you think of the full spectrum Evergrow pattern in my link? Will 2 of those work well for a 75 Gallon tank? I'm not very comfortable doing my own DIY layout as I don't know much about lighting (more than needing the 460 blues), so I was leaning towards their general Full Spectrum layout.
 
Here is a growth shot of some green plate from my reef breeders unit ... top is from 1/27 2nd is from 2/27 and third is from today 3/27 ...
