LED discussion: split from Taotronics-or-Reefbreeders-LED

FYI this tank crashed for unknown reasons. Just adding fuel to B's argument.

I have been thinking of supplementing my radion pro with t5 but I don't know which bulbs would be best.

I may misunderstood your claim, does your process can induce permanent change in the corals that will allow them LED-friendly?

Absolutely not -- when corals are shipped, they are still in a completely dark bag and when you open them and expose them to bright light suddenly, it'll be the same thing. Not to mention, not all LED fixtures are made alike. The difference is, similar to how aqua-cultured corals are "used to" tank like environments, corals that are already acclimatized to LEDs for a period of time, will be more tolerant of going under another LED / strong light source. Proper acclimatization is still strongly recommended.

This was just the first page from google with you search for "acclimating corals to leds" ( http://lmgtfy.com/?q=acclimating+corals+to+leds )

Basically thing to remember, is that temporary low light will not kill the coral (it'll make it brown out), but excessive light will make the coral bleach. Also please remember, with LEDs, even though the tank might not look as bright to the human eye, the corals will feel otherwise That one I can probably find more scientific evidence for but will have to look around again for the article I read last time.

Please PM me or start a new thread under our forum if you have any other questions about LEDs that I might be able to answer.

Are these normal procedures to acclimate corals to a specific light source/spectrum?
How this can become your company's goal and how does it make your company different from regular "shop" as you stated in your post?

Sorry -- I think I'm misunderstanding your first question -- do you mean that's the standard procedure to acclimate corals under any light? if yes, then yes -- that is the standard procedure when going from a lower intensity light to a higher intensity light.

For the second question -- that's not our "only goal" -- The "store" remark was in reference to a different thread. I've a feeling you want to bring this thread on a different topic though so please PM me This topic is wayyyy off the OT

These posts were broken out from another thread to keep both topic going, Enjoy

Also a friendly reminder that the topic is LED's please keep to the topic and direct your questions about sponsors business/business practices to their appropriate forum or contact their representatives via PM or email

As of today I have been growing my corals in a mix and in a full SPS nano tanks under LEDs and things are working very well. I never had the opportunity to use MH for different reasons, so I can't compare. My experience with LEDs is no longer than 9 months, so very short. But I can say that so far they are working in my nano tanks.

Not adding really any new to the thread than just saying that as of today I am happy with LEDs (Truelumen pro and Ecoxotic Marine)

Whenever you change your lighting there is a potential to lose corals.
This is true for even changing a metal halide bulb so i can not see how all these
issues are attributed to LEDs. This discussion has been done for every change.
VHO to MH, MH to T5 and t5 to LEDs. Oddly they have the same type of evolution.
First people believe that they won't work, second they work as a supplement
(MH and VHO, T5s and MH, and T5 and LEDs) and then stand alone.
In addition, each gets more complex. For example, discuss the proper combinations
and types of T5s with anyone and you will get a major list of options.
LEDs are even more complex. They have a wide variety of spectrum, you can build them as a
point source,you can vary their intensities and these features can be programed.
This make comparison difficult. The addition of violet and red leds to supplement
LED lights is fairly new. (Ex Radion Pro early 2012) I can understand the argument to wait a while.
The reviews are still new.

Whether LEDs, T5 or MH it is intensity and spectrum that can be measured and compared.
Many of the current LED designs have issues. Many of the LEDs are run at too high of a wattage.
I have seen many of the Taotronics-or-Reefbreeders led
A couple of issues
You will notice that ecotechs and other high end lights are moving the LEDs closer together
and putting reds, violets and greens in the middle. This is to avoid the disco effect where you see
a band of green and or red in your aquarium. The current Taotronics-or-Reefbreeders have this issue.
Look where the LEDs are located. The light is not as efficient as other LEDs. T5 may be more efficient.
I am currently looking at changing my t5s to LEDs but have not found a cost effective
replacement other than to build my own with a MakerLED kit. I am getting a Taotronics-or-Reefbreeders
and may move some LEDs around (Some soldering required) to use. I have also added LEDs to my t5
using stars with 3 LEDs (9-12 watts) (LED supply) These add intensity and glitter lines (No disco)
Most of what I have read in this thread is true. If you invested in t5s why change?
If you feel comfortable with LEDs why not upgrade?
I would also like to see some one post a wattage comparison to par between t5s and LEDs.
Since LEDs and T5 use phoshors excited by a light source for warm,cool white and both can
create a narrow spectrum source, It looks to be an application and not a technology issue.

 

[CrypticLifeStyle]

What about plasma lights, havnt seen those mentioned yet.

 

[dz6t]

There are commercial plasma lights out there for large aquarium.
But LED do catch on a lot in recently days. I meet a company in china that produce patented LED technology with full continuos spectrum with high CRI. But it is expensive.

 

[jdeb101]

Yes, I've noticed a few ppl mention disco affect with these fixtures however they seem to remedy it by removing the 90 optics or raising the fixture. I plan on using 120 optics (I have a 40 breeder so don't require much depth penetration) which I do not believe anyone has reported disco affect with.

FWIW, I have a Reef Breeders value fixture that comes with two deep reds (and I also added two cyan which they do not come with normally). There is no spot lighting or disco affect from either color. The fixture is about 7" above the water surface IIRC.

However on my DIY build I did on my 28 nano, there is some spot lighting from the one red and one cyan I have. Here the lights are only 2-3" off the surface.

What size tank you got the fixture on Marshall? Got any pics?

125. I have three fixtures, one is the Reef Breeders and then two are "generic" (Evergrow) 120W dimmable fixtures with just blues and whites. Here is an older picture:



At some point I plan to replace the other two with Reef Breeders as well, but all of my SPS are lit by the center light so I haven't had the need yet.

 

[dz6t]

Isn't Reefbreeder LED are made by Evergrow?

 

[Pdm2476]

Dont think so reef breeders is a smaller company out of CT...with amazing customer service I might add very happy with them.

Reefbreeder is Evergrows American company IT-2060 for Evergrow is the Photon 24 for Reefbreeders.
