The lights look dull and no good to the human eye? Really?

Your tank looks pretty good to me. What are the experience from other users?

We've seen several local hobyists cautiously try out one Orphek unit before committing to buy more, without exception, once the first unit is operating, they ALL quickly bought the remainder and haven't looked back.
We've had ours since Oct 2010 and loving the colours it produces, far better than what we were getting with out MH & T5 setups.

Good Luck with your choice, but our money is on Orphek.

im sure it is...

lighting for display tanks needs to be both ascetically pleasing to the owner/viewers but also have the ability to grow and sustain corals. it was said earlier that these lights are more for growth. perhaps the reason there par numbers are high due to the shear number of white leds as opposed to blue.
a 1-15 b-w isnt what myself and many people would call ascetically pleasing. i very much doubt there par numbers would be as good should they do what most brands have done and gone with 50-50 or 2-1.

I guess it is something you need to see in real life to assess... Are they much cheaper than the SR1200 ?

i would say there quite a bit cheaper as vertex really has set the bar for led lighting.

Has everyone seen these?? I was about to buy orphek - but then I seen these... Now sold in Australia, with local warranty. Masa group buy underway. Fully controllable.

Yeah I did see those, I didn't think they were as good as the vertex or the orphex. But some of the members that have signed up for them seem to know their stuff. Perhaps they are a good option ? And a third of the price.

They are not as expensive as Vertex... but share the same LED chip. They look great, and get great reviews.

They are fully controllable, but not via blue tooth wirelessly to your Lap Top like the Austrian Vertex.

I think they sit in between a Vertex and Orphek in terms of what they offer and quality.

They are also $710 from Australian dealer with local warranty. I agree, I dont think they probably are the "ducks nuts" like vertex, but they are not $2000 for a 2ft fitting either.

Do your research well on the orphek. They are not adjustable, and the fittings (the metal strip around the sides particularly) is not the best quality, with miss drilled / finished holes and prone to rusting... I spent the best part of a week googling references etc... I was put off personally by the personal accounts and reviews... I think when you comare to In Water Stingray, they are significantly overpriced for what they are / offer. Just my opinion anyway... and thought the link is worth a look to make sure people have seen these beauties...

Bradies,

Thanks for that mate, really appreciate your opinions. Maybe I should get on the group buy band wagon for the Inwater units ?

Hi, :wavey:
When there is more blue and UV, the PAR is up !
Blue and UV emit more PAR than white led, but less lumens, Orphek now also provides any Ratio that is needed.

I dont want to influence your decision, other than perhaps try to help you make an informed decision.

$710 is still a lot of money in anyones language and I think they are both around this mark.

If something goes wrong with Orphek, where in Brisbane, or Australia do you take it for replacement / repair? I believe you have to send it overseas?? Not a risk / option I am happy with. The distributor for In water is IN australia and ON Masa with an established business.

If your corals start getting light stress, can you dim the orphek? Nope! (You can lift it higher, but not if you have a hood, and not if you dont want light scatter throughout your room). You cant simulate run rise / sun set either - you can with In Water - fully electronically programmable.

Have a google search of Australian and o/sease review articles of Orphek's 2ft fixture.. They are having major quality control issues!

I think the Orpek looks lovely in their perspex case, dont get me wrong... but they are a lot of money for essentially a basic fitting particularly when quality control isnt up there with In water or the Austrian offerings. You can get USA CREE LED Chipped lights from LOCAL distributors out of China in non- programmable fittings for about 50% of what they are charging.

My only advice would be to do your own research, really well... as only you know what your ultimatley prepared to excuse and accept when handing over your hard earned $$.

When testing some par readings earlier this week we did see a consistent higher reading under blue's than white's.

Why would that be so?

Unless they're building their emitters differently to the standard process or using different white/blue origins (as in efficiency series), the baseline PAR should be roughly the same as whites tend to be made of multiple lens coats as opposed to just a single. Photon flux should vary little between the two. That having been said, blues pack an impressive amount of punch which is a big reason a lot of people who've gone to LED supplements have ended up bleaching a reasonable amount of their corals. UV shouldn't impact PAR as it falls outside of the spectrum of recognition, and there's very few LEDs which can actually produce it.

What setting were you using, Rusty? Daylight or electronic?

Not only that Tone, but in the same series of LEDs, blues and whites should be effectively the same as they're built around the same actual platform. Whites are effectively just blues with more coatings in most builds :)

I think I am still leaning towards the Orpheks. They seem to have designed an LED that suit Coral growth.

They also now allow customisation of the blue/white ratios which should help with their aesthetic appearance.

having dimmable light or storm cycles do not really interested me... my MH just turn on...

Pretty much any LED on the market currently suits coral growth for what it's worth, and I struggle to think of a fixture that doesn't offer at least some level of customisation :)

With 90º FWHM lenses out of 160lm/W emitters? Unless someone is hiding something about physics here, that wouldn't be any real benefit beyond anything else out there, Jez.

On what grounds are these units far and above superior to any other product on the market, exactly? Actual objective grounds I mean, not (often somewhat inaccurate or misleading) sales hype which thus far seems to the Orphek's preferred means of information provision. The Sturm und Drang if you will :)

I did say 'maybe' Ben, it seemed to be the big selling point when I looked into them many months ago but i wasn't convinced they were good value for the money either.

So would AI's Sol Blue be a better buy? I think Vertex is a bit out of the budget, 3.5k for a 1200 light is ridiculous...
