I want to add this I do not think leds will ever do as good of lighting job or provide as good of light in most cases than fluorescent or halides.. Leds are very good at putting light where it needs to be and very good at task lighting or spot lighting and nothing beats leds in those applications.
The advantages to leds like energy efficiency and being able to dim may out weight the advantages of other lighting but the actually lighting will not be as good. It will get better and close the gap. It is the way leds produce light and the small point source that is very hard to over come.

"What is the perfect light source".. "There isn't one"...

I've talked to Tullio many times too.?? Why did you post this to me?
I have seen this video a while back. I know Tullio pretty well. I met him when he first started dating Joy..
I have had many conversations with him. He knows lighting very well and plays the guitar very well too.
I have known joy since she ran harbor aquatics out of the green house in her back yard. She later went to work for PFO lighting when the business became to much for her several years after her husband Gary died at Macna.
Tulllio is the guy I see eye to eye most with when it comes to lighting..
I actually met Dana for the first time at a talk Tullio was giving at Imac along time ago. I didn't know I was even talking with Dana until later. Never met him face to face till then but I knew Dana through fishnet many many years earlier. Other than online I do not know Dana to well, I just have met him a few times at conferences and was able to talk with him for a bit. He knows more than anyone about how light affects coral.
All are very nice people and very knowledgeable.
When Joy worked for PFO lighting she sold the Solaris which was one of the first led fixtures in the hobby. I was one of the first to see it. I also got to see one of Tullios first led fixtures. I can not remember who Tullio worked for then, might have been IceCap? Dana, do you remember?
Perfect would be the sun.

It is a hobby but I will still call out unsubstantiated claims like leds cause weaker sps skeletons.That's totally fine with me. Do whatever you like.
Trust whoever you want to trust.
This is just a hobby.
I have a problem here you contradict yourself in a couple places. You say there is no better than another it’s a matter of taste. Later on you say all these people coral growers etc tried halides and say they are much better and you ask are they lying. Well who cares what they think if it’s a matter of taste. ?That's OK if you LED boys and girls love your tank as they are! Oh man...
The bad thing, and I believe the beginning of this harsh environment with discussions that never end, was when companies started to compare their LEDs with halides trying to show they LEDs are better to sell, using halides side by side, the best available source of light for reefs, as a step. That is a lie! See, the LED companies started saying LEDs are better than halides, not the reefers/consumers. They are different light sources and will NEVER give you the SAME results!!!!!
Even T5s will NEVER give you what you can achieve with halides. PERIOD!
There is no hate. There is no "better than other".
It's a matter of taste. Once more...
If you want to have your corals surviving with dead spots under them, weaker skeletons, and colored by the blue diodes (thinking those are natural pigments) and think they are "growing just fine" that is your reality. That is fine with all of us. Really! I mean it, I think we all know better. That is your tank! Some people have more LEDs over their tanks and that will diminish a bit those symptoms listed above. Spend thousands of dollars that way with Phillips or Lani LEDs and you can try get close to a T5 system, like the ones in Europe. Make your own fixture with the VERY BEST LEDS you can get!! Not going to be like the halides NEVER because they are DIFFERENT and no LED will provide what halides are able to. NEVER! Period! I'm sorry, but that's not hard to understand.
Facts are facts.
If you don't believe me you try out and come back here.
Or do you think all the people who were LED lovers before and came to apologize to me saying "I should have listen to you earlier" are lying?
Do you think all those guys in this forum, including corals growers, that went try halides over the so called "best LEDs" they had and published they can't believe the difference and halides are much better are lying too? Man, results are what we all want. You choose your "results".
If you really need the techonology to play wifi, thunder, blue fluorescence, purple psych, etc... forget halides. But if you want to impress your girlfriend, grandma and the kids get halides. They will tell you the truth. ;Drool
Ps: and I won't reply to those out of the context quotes. Sorry.
Oh goodness don't get him started...I have a problem here you contradict yourself in a couple places. You say there is no better than another it’s a matter of taste.

It seems to me that certain halide loving posters are a little over exuberant in crusading for their favourite lighting which I find highly amusing. To me, water chemistry has been the single largest factor in determining coral keeping success for my tanks.I have a problem here you contradict yourself in a couple places. You say there is no better than another it’s a matter of taste. Later on you say all these people coral growers etc tried halides and say they are much better and you ask are they lying.

Under LEDs, in my observation and after talking to many people with experience, they won't produce stronger skeletons like under halides or under the sun.It is a hobby but I will still call out unsubstantiated claims like leds cause weaker sps skeletons.
Please ignore me. LOL!Oh goodness don't get him started...
Ok, I'll explain.I have a problem here you contradict yourself in a couple places. You say there is no better than another it’s a matter of taste.

That is an observation. I wouldn't call opinion or a claim.
Please read past posts and you will find more.
Another thing, taking advantage of this posts, is the tremendous ability of natural pigment production, besides pigments from elements. Halides will certainly be the king of pigment formation. It's just facts. Observation by many.
Hence it’s your observation and NOT a fact. Don’t confuse the two.Under LEDs, in my observation and after talking to many people with experience, they won't produce stronger skeletons like under halides or under the sun.

Its actually an opinion and a claim - based on an observation. Here is another observation - the vast majority of people who have read the poll and taken it are not - and are not planning to use MH lighting. Why do you think this is? Not a rhetorical question - I'm just wondering if you can step outside your opinion - and try to think about why others don't agree?
Hence it’s your observation and NOT a fact. Don’t confuse the two.
Not real scientific here. But I would assert that if 10 people responded “not planning on using mh lighting” I would estimate
8: because it’s “dated tech” and not aesthetically pleasing or low profile enough, the “they’re too hot and bulb changes are SUCH a hassle” rhetoric is strong with these ones as well
1: used them previously and just flat out like the aesthetic of other options more, willing to sacrifice the subtle differences in growth and structure (if there even are any at a high enough level) for the specific color rendering of t5 or led
1: people that respect them as a viable option, but just didn’t start with them and are satisfied enough with what they presently use. More passive hobbyists.
I was just trying to bring the thread back to the OP - rather than this back and forth about what is better. The fact is - whether MH is better or not - people aren't flocking to it. I think that is a more interesting discussion.
