It's time, let's see those SPS tanks using LEDs 1 year or longer

[Moser]

We've already gone over this. photos are touched up. coral color is completely different.

So, you have now claimed that both Dave and Ehsan are being dishonest with their led claims?. I think we should be clear about what you are insinuating, as the claims they make are very important in decision making for many enthusiasts.

I have heard several accounts from visitors to Ehsan's tank in Germany claiming that the colours are simply awesome. Even Luc Loyen says this and he introduced that tank and video to us. I have also seen several mobile phone pictures without touch up confirm how good the colours are.

Just dismissing that tank and it's coral colours is unfair. Some acknowledgement has to be forthcoming.....

The pictures speak for themselves. Polyps don't change color based on angle. the corals are totally different colors based on pics. I've asked you to link this tank several times. Can someone link this tank for me?

The photo's were taken with different camera's.
The first with an Olympus point and shoot, with auto setting (exposure, white balance etc.) and the second with a Canon 7D. Of course the colours look different.
So before commenting on photo's being "doctored/photoshopped", perhaps actually gain some technical knowledge about photography.

The corals look very nice to me.

 

[Moser]

There isn't a link. It was just a video Luc Loyen posted. It is a display tank in a shop in Germany.

Having a nano tank yourself, I think my point has passed you by.

In my tank, my Desalwii looks much duller from the front as it has been slightly high up, so you cant see on top of the coral. The green polyps appear brownish from the front. I showed you a 10k mh picture.

When I lower the coral in the tank and look down on it, or look top down, I get the same effect as Ehsan ie the green becomse vivid, so I disagree with you - depending on viewing angle, in a large tank, when the coral is 5ft away, you can get this effect.

The photos from my tank were from 10k mh and actinic t5. Ehsans close up was in20k mode,I believe. The other one was lower kelvin viewed from a different angle from a distance.

I just saw this tank- I think it's nice - comments?.

Yeah, because someone actually knows that the pics were taken with two different cameras without looking at the meta data or being told

I would like to read up on the stats of this tank. How long it's been under LEDs, etc.

What LED strips are these in the reflection? They almost look like T5 bulbs

This tank is in Hong Kong. Not sure if Eric still has the tank running.

Link to his tank is here

60 gallons is not a nano. And I know what you're trying to say, but it doesn't fly. SPS look more colorful in top down views, but in these pictures you can still see the tops of the corals and the coral polyps. I've been around the block long enough to know that there isn't some sort of magical transformation regardless of tank size like when looking at a clam.

If we were seeing the dark side or underside of the coral like the pictures of my tank, I'd nod my head. What you are proposing is patently false. I can buy the difference being attributed to white balance, a different Kelvin rating, a different intensity, and a different Kelvin.

In regards to the tank you posted... it's a Zeovit, and usually traditionally lit zeovit tanks look like candyland and this tank is another muted tank. You posted another example of LEDs not producing the color results of traditional lighting.

It's very easy to see what camera's were used. There are lots of exif data viewers for photographs.

Agree those are definitely T5 tube reflections though.

I flicked through the video and although it is claimed I am dense, that stuff isn't new to me!.
It's why I keep saying acclimation to LED's is very important regardless of how bright or dim you think the LED is!. The spectrum with LED's is important and the amount of each wavelength is critical.

Thanks though!.

Mo

Unfortunately Mo you aren't getting it..................you're completey misunderstanding the facts presented in that video.

To all,
I don't want to get involved with technical aspects in this thread, so I started a thread in the lighting forum to explain & ask for input about LED units.

Maybe we are debating in the same way of long play records VS compact disc or film VS digital camera.
New technology will overcome but it must take time to develop.
Happy reefing guys.

I don't think anyone is is arguing that the new technology will overcome & take time to develop.

That wasn't the point of the thread..........

What's out there that can be bought today or over the past year that someone can put over their tank & be succesful is what this thread was about.

These units have been out long enough to evaluate. If someone has a DIY unit that has worked that's fine......we can copy it.

If someone has a commercial unit.......then lets see the results over the past year.

Since the thread was initially posted it's been crickets for a long time like Med Red said.

Lol. If you read this thread carefully, you'll realise whose tank it's from and that they are MH and T5 shots to illustrate that viewed from different angles and different spectrum, the same coral can look completely different without resorting to photoshop. It was in response to your comment that Ehsan's Desalwii was brown and not green.

Behave dude!, qualify your statement about how I don't get it.
BTW, before you challenge my intellect too, I should tell you I have a degree in optics amongst a few others. I wrote a thesis at university on the response of the eye to photodynamic radiation.

No it hasn't!!. We've posted quite a few tanks of a relatively new technology and had a few anecdotal comments from a few closed minds.

Don't forget, I run a MH/t5 tank!. I just have an open mind!!

I think that is the issue Mo. People don't like when their eyes respond to something nice, shortly after they have spent a fortune on trying to achieve the same results using completely different equipment. :lol:


...I jest of course, but LED bashers need to find something else to moan about, there really isn't anything to doubt about their ability to light a reef tank. The only issue is their "value" and finding the right units suitable to each individual tank.

In most cases, a T5 unit or a mix of lighting sources is probably a better option, but an all LED tank will work if set up correctly.

 

[myzislow]

Wow!, Hang on, let's not get too personal!.

I just want somebody to say "Dave is lying". Is that what you are all saying?. I don't wish to paraphrase, I just want somebody to stand up and say it, because I didn't see any evidence to support that.

Also, be careful who you call dense. You don't know what I do or what my level of intelligence is. However, you might get a surprise!.

Mo

I sent you a PM. Is this a threat? Talk about getting too personal....

So is this pic LED or MH and T5?

As I stated above, I still had BOTH of my LED setups when I changed over to MH. If the difference wasn't so stacked against LEDS I could have easily sold the MH fixture for what I paid with it and stuck with LEDs. Have you read my build thread? I am meticulous. Again, as stated, the reason I got rid of LEDs wasn't because of a failure. My eyes were able to see the aesthetic difference and pick up on the "missing" colors and nuances that have yet to be shown on an LED tank.

Of course there is something to doubt about their ability to light a reef when the majority of the evidence shows that they don't produce the color that you get with traditional lighting.

 

[MedRed]

Oh yeah... I ran both of Eshan's images thrgouh pskiller.com to check for photshopping tags... they both came back positive for photoshop tags. I cropped my pictures in photoshop that I posted above and tested one... no photoshop tag... interesting.

 

[bigbuckdown]

I think ALL you guys got off the original point of this thread. He wants to see peoples LEDs who have been running them for more then 1 year. Everyone wants to prove they are right but no one will be and you will argue till your fingers are sore. I for one ran 2 250 mh on my 120, 6 bulb t-5 on my 50 and acan/AI sol blue on my 92 corner. I am in much defense for my LEDs. Sure the color is not the same but its not far off from what the other lighting will give you. I am extremely happy on the switch and will never go back. My growth is incredible, my tyank stays at a stable temperature WITHOUT running a chiller and i can have any spectrum of light i want on any given day. You guys really need to relax and realize its just a aquarium,its just a hobby have fun and stop letting your blood pressure rise because of someone elses opinion. And if someone is photo shopping his pics just to prove he/she is right you really need to feel bad for that person because there is nothing else exciting happening in his/her life that they have to spend hours on a computer to prove they are right. BREATHE LMAO

When people start talking about photoshop as an argument against something I lose interest, big time.

I'm sorry you prefer to stick your finger in your ears. I'm looking for the facts... good, bad, or ugly
