Yea ianwraab is right I take that back I haven't heard bad things from ali express ... As long as they stick by there 3 year warranty theyy might be the best....
This is with the shipping back and forth to china after the first year if something goes wrong that could add up or you have to know how to install it on your own and they will send you parts but I guess that's better then being SOL lol |

Anyone can sell on ebay even you. But they are warrenteed by the manufacturer. New Egg might have a 30 day return policy but after that they will probably tell you the same as an ebay seller. Last edited by kbell2433; 05/07/2012 at 10:21 AM. |

Yea as of now I am leaning towards these aliexpress ones or the aquarium leds one.....
Also sam emailed me and cleared up the coverage thing he is gonna email me back with an exact coverage area later but he said at around 15 inches on height it will cover a 24" long area. So my apology for my earlier post on the coverage of there units sounding poor it was a misunderstanding |

Your PAR Ratings might bevery high on all of those, however they will be about 40% less once you actually put them above water. You lose a significant amount of Par as soon as the water reflects the light out. |

the above numbers are interesting. But it would be much more practical if the numbers were taken at various heights up to 30" above the sensor level. Then ploted to see what kind of spread those par numbers are creating.
What I find interesting though is that par numbers for Blues is higher than the PAr numbers for the whites? This fixture must have a lot more Blue LED's in it than white LED's. While that is good point remember PAR meters are generaly more sensative to red light than blue light. But corals love blue light more than red light. Unfortunatly if you ran these same test also with three different brands of PAR meters you would probably get three different sets of numbers as well.

So true

But honestly... If I can build it then a manufacturing company can mass produce... Do you buy generic medication or pay 40% more or name brand? Why do you think generic is cheaper... Not made under same US laws... Aka overseas or Canada... You care more for your tank then your body? LEDs are simple stuff..they'd guys bought a schematic, bought a ton of material in bulk... Not they sell cheep to move product. .some company's put a blue temp readout on there lights and charge $200 more look at the mid range models vs. the high range models...cuz it looks cool can cost a bunch too ya know... |

To give you an example. I bought a remote controlled helicopter. It was bad out of the box. They said: okay ship it back. Its a 2 lb item. Cost $50. Shipping cost to HK by regular untracked mail is $25 or so from USPS. Now imagine you have to send a 20 lb light. Not discouraging completely, but just be aware.

Does anyone sell a leg bracket for these? I'm not too fond of hanging it, and my tank is right up against a wall, so I cant use the Aquaticlife hanging stand kit.

Well maybe...

As with any major electronic purchase Gather info, make decision, hope for best... Remember the Chinese are building what we are buying and there is a big market for LEDs grow lights in America and Canada... I'm worked for years in logistics and CPU manufacturing If it's made in china and warehoused in America it's gonna cost more just because of that..Because the US retailer is importing and paying rent,utilities, and salaries (all cost more in America then china ) these company's pass that bill straight to the end customer.( still think you get what you pay for?) If my fixture breaks I can buy a brand new fixture and still not have spent as much as a name brand would cost.... Lastly remember ALL OF THE FIXTURES WE ARE TALKING ABOUT ARE MADE IN CHINA!TIWAN!OR JAPAN! Ps... My light is 4 lbs and ill most likely ask for replacement parts to fix myself to save time and money... If your light gets damaged shipping back to manufacturer then it voids the warranty... Best to hand deliver or ask for replacement parts ... |

I figured out a cheap DIY solution to the lack of leg mounts for this kit. I'm going to use my old metal halide kit legs and either run an adjustable track from leg to leg, or just glue a sturdy piece of wood/metal or plastic from leg to leg. I'll then use tape, glue, or velcro to attach to the led unit. I can glue two pieces of wood width wise for further stability.
The legs can be found here. It has the option to be adjustable, and I don't have to drill into my ceiling, stand, or walls. Total cost < $20. http://www.ebay.com/itm/Mounting-Leg...ht_1619wt_1026 Last edited by bhazard451; 05/08/2012 at 01:21 PM. |

24Xwhat? The 120' optics will have more spred less penetration, The 90's will hit the bottom stronger, BUT might burn anything thats too high.

Have you guys looked at reefcatalyst.com. I talked to Marcello from there today and they sound really good. They are also on YouTube. Does anyone know what happen to nanocustom.com? They had some good lighting for small tanks.

I know my last post was off topic a little. I'm sorry. I read all 50 pages of this thread and I have to say although I'm very interested in the China black box LEDs, I a little skeptical of them. I need more good news about them.

Does anyone have a picture of how the different optics look? For example: 120 degrees 90 degrees 60 degrees. How do I know what my lights have?
