I know there are loads of information all over forums on these Chinese LEDs but all the info I have found is a few years old. Does anyone run them and have pics of their performance I am curious and where did you buy them.
I've been running Green Element lights for over two years now. They aren't blue or fancy, but they get the job done very well for my purposes. I prefer a more natural sunlit look personally, and I'm OK with a pretty white light. I had a 36" dual 3W (two rows, I think it was 24 x 3W LEDs) set over a 30 gallon mixed reef that did very well, and now on my 90 I have a 48" quad 3W (4 rows) with a timer and I am extremely happy with it. I'm using the two row one on my 50 gallon FW tank now and it's growing some nice plants for me now
Here's a shot of the 90 - been going on 6 months now:
and the 30 in it's best time:
I bought them from an ebay store called "Topdog Sellers" that ships from Texas so it only takes about a week to get them, and the 48" light was only $225.
I run 4 of em in my 300 Reef and stuff seems to grow pretty well. Doesn't appear to grow as fast as my frag tank with (2) 150 metal halides, but it stays WAY cooler, looks way better....and generally works better for me. I'm not looking for fast growth though....so I'm OK with the slighter slower growth.
I got mine secondhand from 2 different sources. I'm running (2) 72 watt Chinese LEDs with Cree LEDs, and (2) 120 watt dimmable Chinese Leds with Bridgelux LEDs.
Unsure on model numbers off my head though.
the 120s look like this though:
Here is a shot of my tank with dual lighting styles as well. One side is 150 watt Metal Halides...the other is (2) 72 watt Chinese LEDS. This was a testing phase I did for @ 3 months. Now I'm full LED.
I dunno wright....the 3W bridgelux seem to be pretty decent. Without a PAR Meter....they seem pretty darn bright. Possibly brighter than the Cree that I have. Both seem to be good names in LEDs, but Cree is a little more well known I think.
My 72 watt Cree units are noticeable less bright than my 120 watt Bridgelux units. Only difference is there is less of them on the 72W unit.
It's according to which Crees you have also. Theirs a big difference between them. Standard Crees or the rebels etc. you'll be replacing the bridgelux years before you'll replace the Crees. Also the par value is way lower than Cree. It's like comparing a pinto to a Lamborghini. Lol.
It also comes down to what you like and what you can afford and cost to run. I rather run good and fewer quality units than more units that's going to use more power and not last as long. But that's just my opinion.
