It is comparing the features of the fixtures not giving any review of the fixtures, open them up and lets see a side by side comparison of the lights in operation.  lol It is a great article for features though. |

Here is a comment I found on an LED article I thought was great.
"People tend defend what they buy or what they perceive based on hype and a good marketing campaign."

Just remove the optics Sent from my HTC6525LVW using proboards Exactly. Instead of running the lights at 40% with optics to avoid burning the corals since the light is so concentrated, remove the optics and run the lights at 80%. |

Here is a comment I found on an LED article I thought was great. "People tend defend what they buy or what they perceive based on hype and a good marketing campaign." This holds true to all kinds of lighting though.not just leds you defend mh and t5's like people don't already know they are a viable and proven lighting for reef aquariums. People defend what they know and believe in, in all facets of life. I think the best question to ask you would be, what do you have against leds? |

mike patetta saying every thing you want to hear about mh and leds. To bad the test won't be done for awhile.

People defend what they know and believe in, in all facets of life. I think the best question to ask you would be, what do you have against leds? If your re read my posts I stated that I think LEDs will be the aquarium lighting of the future. I think that MH and T-5's are at the of their cycle and seeing that most of the phosphor blends have been utilized and no effort for development of new phosphors are being made. I have an article I will post later that I agree with 85% that will help you understand why some of the LED fixtures do not work for reef lighting. I hate to post this because the author leans heavily towards one type of LED and I wonder what his involvement with the LED company is even though he stated he has nothing to do with them. I do defend things that work because I have gone the roué of trying the latest and greatest and most of the time the latest and greatest for the most part end up having problems or side effects. Also as many people in the hobby I have a lot on money invested in my tank and taking a risk at this time listening to something that someone says works is not a risk I want to take. IMO. |

I understand everything your saying but....... There's many people on this one forum with great success with different kinds, types and brands of led fixtures on reef aquariums so I don't think only one kind of fixture works.
Either way I completely understand and partially agree with what your saying. Mainly because there's so many company's out there right now throwing a bunch of parts and cheap diodes(calling them cree) together with limited experience in reef lighting and call it a reef capable lighting fixture w/ "full spectrum" when in fact they aren't half off what they say they are! Not to mention the fire hazards these people are selling! Every fixture should come complete with a fire extinguisher. Imo
These are the fixtures you need to worry about. I think there's many led fixtures that have proven them selves already though and even some of the cheap Chinese leds have had great success. Mine did for awhile and still does, it's completely a problem with the workmanship and not the capabilities. I've had great success with my light besides that.

But again what are you calling success? Some corals live and a few grow and strive? Lots of corals will adapt to the light that is put over them but would you rather them adapt or would you rather they live in an environment close as possible to their own. The Chinese fixtures shifted from the Blue white spectrum which were the first generation of fixtures out of China to this so called full spectrum lighting which included the addition of Warm white, Red, purple, and green LED's. There to this day is no scientific proof that the WW, red, purple, and Green LEDs do anything to the spectrum or wavelength other than making the tank look pretty for the Hobbyist.

with led the only issue I have ever had was when I used only "white" and "blue" I lost some colors in corals, and as stated above some corals did better some didnt. I bought the led with different colors of led and got color back+ new colors on corals and everything started growing very fast again..
not scientific proof but I saw it with my own eyes so it works for me. I am the type that will have to try it myself.

I was at Ricks today. He moved the Australian Duncan-like coral from the led's to the 400 watt MH tank.... Wow!  Yes, there are other factors at play; water quality difference, temperature... Etc.. But it is gorgeous!!! Never saw it out in the long tank. I really would like MH, cost to run and heat are huge obstacles. |

Did you watch that video where Mike palette is going to run leds all day with mh for 3 hours a day(mid day) to get optional coloration and optional growth?
Very interesting video and a great idea but the test won't be finished for 6-9 months. blah!

did you see that duncan under the led? I got a piece of it at the swap, it looks amazing under my led...
the problem with a 6' t5 is $400 to replace bulbs every year....

I am the type that will have to try it myself. Yes but your fixture was probably one of the first generation fixtures with the junk LEDs in it so any LED fixture would be better then that one. Just because the light visible to the eye is blue and white does not mean it is a temperature or spectrum corals can use. My guess and opinion would be that the Blue and White LEDs were a better LEDs in the new fixture they, may have even been higher wattage and were more in the spectrum and temperature the corals needed to thrive . The Greens, Reds, Warm whites, and Purples did nothing for the corals but raise PUR (which would have been done with Whites and Blues) and bring out some colors. What is comes down to is if your corals are thriving and you are happy with the way your tank looks that is the light for you. As I stated before I don't care for some of the characteristics of Just LED lighting, now LED and T-5 hybrid now were talking  . Next question is 400.00 to relight t-5's are you importing specialty lights from Germany? Hellolights has blowout sales twice a year where their 60" lamps are 60 to 70% off So even at 40.00 a lamp 6 would be 260.00 with shipping. 60" lamps are an off size anyways, so Myself I would be doing a DIY fixture using Either staggered 36" or either better Staggered 48" lamps over that puppy. Even at 8 Lamps at 25.00 each you are looking 220.00 with shipping buying the lamps at full price. I am on 19 months with my 39w T-5's and just falling out of Par and Lumen output. |

I've seen a TON of pictures from everyone else on this forum is there anyway you could post some pictures of your corals under your current lights? I'm very intrigued to see what kind of stuff your growing and how your results are with the lights you have? |
