I'm glad there's still someone out there like Tullio that takes a scientific approach to explaining reef lighting. Years back when I was less busy I wrote about 15 pages specifically breaking down the advantages, disadvantages, and scientific principles at work in the delivery of light to reef animals by the 3 primary light technologies we currently use. My business has grown so busy that sadly I have not had time to finish what was supposed to be a 30 pg guidebook or so. Maybe one day when I find more time I will pick it up and finish it out. Still have to complete the few pages on Lambertian emittance which is my absolute favorite factor in light delivery to corals. I run only T5 on my current systems, but in terms of emulation of sunlight, both in it's color blending and point source delivery, metal halide reigns king and likely always will. Unless a true 'full spectrum' mega diode led is ever developed I don't think there's any chance of halide being dethroned.Mr. Aquila is very serious about light, isn't he?
He is actually a professional that works with LEDs for a long time!
His comparison of artificial light for aquariums and the sun is the goal we all should look for.
I love to hear him talking about metal halides. That guy is just in love with halides, man!!!
"...here is the big one, here is the big one!!..."
I think he has been watching us here discussing in the forum?!?!! ;Wideyed
The video just confirmed lot's of thoughts I had about LEDs and I couldn't explain in any way.
The optics and loss of lumens' efficiency of the LEDs... absolutely not like the halides. Period.
And halides have gotten better and better... The Ushio guys confirmed that too. That is so great!! Good news!
He didn't want to say one is better than the other, but he actually showed that! @26:56
Remember: he is not favoring MHs, he just set the facts (specially the production of UV)!!! So nice he is.
He also confirmed to us about the cooling of the ATI T5 fixture as the best way of efficiency for he bulbs increasing lamp life...
It is what it is, my friends.
Metal halides are probably the reef lights of the past, present AND future.
Efficiency... efficiency...
Thanks Mr. Aquila and BRS!!

I'm waiting for your booklet to be published, Sr!I'm glad there's still someone out there like Tullio that takes a scientific approach to explaining reef lighting.

Totally agree. I would much rather throw my expendable income at corals than the ground. Not to mention the fact that, as I live in the Dallas/Fort Worth Metroplex, using MH would cause me to have to spend a fortune on AC and/or fans and chillers to keep my tank from boiling.The problem with MH is, was, has and always will be heat loss AKA energy you're just wasting. It's literally the equivalent of walking outside, opening up your wallet and throwing money on the ground. If there was a way to solve this or if it wasn't a reality T5 and LEDs wouldn't even exist in this hobby. Unfortunately for people like grandis there they do. The sad part is I don't think anybody has ever argued with him that MH are a great light source. The sad part is he refuses to see that there could possibly be any benefits to LEDs what-so-ever because he is so far down the rabbit hole as a "MH Extremist" that he refutes any relevant data however possible.
Presentations like this one are great though as it would explain to some people why "130W" ficture from say Orbit Marine is not the same as a "130W" fixture from like AI. Watts mean nothing and honestly the best info BRS gives us in it's review series is and always has been the spectral graphs combined with PAR numbers. Those give us as close to complete data as we can get on our hobbyist fixtures as we can possibly hope for.
