Best overall led fixture

[oreo54]

I've heard Philips will bring their coral fixture to the US. I've also heard claims that it produces the best light for corals, but their test results differed from mine (possibly due to differences of zoox clade within the coral, which opens up a can of worms.) Tim Wijgerde and I discussed this after this article was published:

Effects of Different Spectra Generated by LEDs on Growth of the Stony Coral Porites lobata

Stony coral nubbins (tentatively identified as Porites lobata; see Figure 1) were exposed to light of the same intensity (128 µmolm²sec) but different spectra for 75 days. Growth rates were determined by weighing the fragments periodically with an analytical balance.

Was that the right link?

Conclusion and Discussion

All LED luminaires promoted coral growth over the course of the 75 day procedure and although there were differences, they were not statistically significant.

Coralvue is bring it the the USA and I believe it is a second generation now.

Hurry and alert the fanboys!! I personally use orphek v4s and thought that was the best at the time of purchase. So far it has been great.

Let's use your list. Which fixtures have the best overall performance in all those categories.

I understand that everyone has different needs with their tanks, I'm just looking for which fixture has the best overall ratings. This is to give me an idea where to start looking.

Someone else will have to field those as I don’t use leds as my primary light source, so I can’t speak from experience only from research. Those questions are appropriate for any type reef light though.

Yes. My testing found no statistical differences, while others claim their light is best for coral growth.

We are using Noop lights in our new build. I've seen them in person. Nice! My son insists on thunderstorms on the new tank. Y'all will have to help me make that happen.

Thanks Dave. I'll check into it.

Ahhh.. Think I got you now.. Notice I didn't mention spectrum..a completely other animal. Since everything from, at a minimum, of 6500K to almost pure blue "works".. that's a whole other can of worms..

From a trust/design/quality factor/engineer aspect..

I trust their work on spectrum though, of course it's relative..

You can look on the Coralvue sponsor, they post yesterday a video « coralvue behind the scenes » and near the end they talk and show a little bit the new lamp Phillips v2.

I wonder if Gen 2 has a spectrum better than once was claimed to be best. LOL.

 

[Murica]

Thank you all this was very helpful!

Compared to the previous versions, the new lights stimulate more fluorescence in the corals. The diffusion plate called ‘light guide’ now features four non-diffuse areas with white leds behind these. This feature enables the light to produce a subtle shimmering effect while still avoiding any ‘discoballing’. The tank is lit as even as it would have been lit with a large bank of T5 units while still featuring some shimmering. Especially when the lights are mounted close to the water surface, this subtle shimmering effect is clearly visible.

gotta play to the market..

"Since 2016 I’m using the Philips Coralcare units. One of the major design goals was coral growth. Philips has succeeded in offering lights that grow coral very well ..."

LOL....

New spectrum.. 6500-sat blue

assume whites are 70CRI..

Sorry I know this sounds like an adv. blurb but unintended..
Not sure what the "old" spectrum breakdown was..

Channel 1 would most likely need to be off for 6500k..sort of obvious..

Not to threadjack, but thunderstorms is useless feature that just scares fish into hiding or jumping out of the tank (if you dont have your top covered) Does nothing for corals at all.

Many led users: gradual ramping up and down is ESSENTIAL for reduced stress and improved comfort and health of fish and corals. Rapid on and off CANT be good for them

Those same led users: lightening flash effects are an important feature of my lights. It’s cool having the lights go from dark to 100% in a rapid strobing manner

Y’all fess up now. You know good and well that accurately describes many of you

Let's look at what can happen in nature (and it happens a lot in Hawaii.) A storm blows through, and heavy cloud cover quickly gives way to industrial strength sunlight. It takes about 20 minutes for all the photosynthetic channels to ramp up. Agree that the storm (lightning) feature is a gimmick.

When I first started out the "storm effect" was something I wanted because it was cool. Now I could care less and just want something that will keep my coral growing and healthy

On a STRICTLY cosmetic basis.. cloud cover is kind of cool though you sort of get immune to it after awhile...
Unlike nat. sunlight you aren't going from 100PAR to 2000...

As to lightning.. should be banned.. (just kidding ) but yung-uns do like it and has it's uses in things like herbariums, natural gardens ect..
Nobody makes you use them..
t5's mh's un-ramped LED's have 2 "storm" periods per day..sort of..
Philips doesn't incorporate it.. Sorry couldn't resist..
There are probably 100 "functions" in my phone I could live without..

 

[Waynerock]

Thats why I use the saxby light schedule it does a great job simulating cloud cover and the tank always looks a little different. I know the die hard users will disagree with me but I have 3 prime 16s over my tank and I have zero complaints or wants

 

[Bpb]

The strange contradiction actually had just occurred to me as I was writing up the satirical post. (Meant to be funny not trying to spark a debate).

I agree the Philips fixture looks like a very good option. If I were in the market I’d be giving it heavy consideration.
