Yeah, I imagine those TrueLumens are like the Current Orbit led fixture.

So, back to the original topic- LEDs leave metal halide and T5 in the dust. Even my "grossly inferior" Chinese panels penetrate the water better than T5 or MH with almost no heat and much less electricity. I don't believe them (my units) to be as strong as a 400 watt halide, but definitely can penetrate as good or better than a 250 watt halide. Perhaps even a 400 watt halide with a 20k bulb in it even. I don't remember satisfying acropora 30" away with 20k XM in a lumenarc reflector, but then again, it's been a while. If I recall, acros did good about half way up the rock, in my last metal halide tank.

T5 vs. MH vs. LED

I agree, MH has been the universal standard for many years. But like cathode ray television sets, flat screens are here to stay. As in all new technologies that supplant older more refined technologies, the first tries are sometime lacking. LEDs have matured drastically in just the last few years. Using appropriate lenses and LEDs you should be able to design for pretty deep penetration. At least as much as a MH in a reflector.

Well, after looking around, vacillating back and forth I finally decided that for the $$$, those LED units really are a bargain.

So I rolled the dice and ordered one of these;
http://www.amazon.com/gp/product/B00...?ie=UTF8&psc=1
Galaxyhydro™ Led 55x3w Dimmable 165w Full Spectrum LED Aquarium Light
Product Specifications:

Dimensions: 15.8 x 8.4 x 2.4 inches
Weight: 7.9 pounds
Output Power: 55pcs*3watt
Power Consumption: 120W+/-3%
Warranty: 1 year
Lifespan: 30000 hours
Worldwide Voltage: AC85~265V
Working Voltage: 23V
Working Current: 1.2A
View Angle of LEDs: 90 degree lens
Dimmer One(28 LEDs) 16 x Cool White 14,000k 6 x Warm white 2700k 4x Red 660nm Green 520
Dimmer One(27 LEDs) 20 x Blue 460nm 4 x Purple 410nm 3 x Moonlight Blue
Using: suitable for a 20 to 50 Gallon tank
Recommend Height: 0.3 m- 2 m

So it has essentially the same specs on paper as the Taotronics 165watt unit,
it will be here in about a week so we will see how it performs.

I had some credit sitting in my account so it cost me less than $90 out of pocket and I can't even DIY a standard output T5 set-up for that much.

So I humbly bow and acquiesce to you guys on the subject of cheap Chinese LED units.

You are probably going to end up removing those optics (you won't need them and the spread is greatly compromised), and I personally prefer less reds, but it will definitely grow corals.

I like the red and even green, corals don't care but I like it. I would look at the spread first. Some emitters the lens is not removable. Certainly the older panels they weren't. I sure hope after all this that that panel lasts you for years.

yeah, roll of the dice, but can't argue with the price, less than I could DIY a fluorescent set-up. not a hard choice.
the company mainly sells light setups for hydroponic gardening and they seem to have a good reputation in that market, so I hope the same applies to their foray into the aquarium market.
my tank is only 36x15x20 so I'm sure it will be plenty.


I also ordered a custom display/refugium today from this guy;
Amazon.com: Windridercreations: Pet Supplies
e-mailed him direct, talked on the phone, will be in here in about 10 days.

decent prices for his sump kits and pre-built stuff also.
