Orphek or AI

[mr.wilson]

A year ago it was absolutely true that a DIY LED was better than an off the rack model. The aquarium lighting industry cannot turn on a dime; once a company has commited significant R&D money on a technology they can't drop it and change to the newest components. There are UL/CSA issues as well as the American patent and supply restraints. The current third generation LED cannot be emulated with a DIY project. Drivers are tuned to custom Phosphor coated high Kelvin chips and lenses are custom ground. Heatsinks are getting high tech and incorporate quieter fans. A year ago Cree or Luxeon LEDs were much brighter than the older outmoded Philips, but now you can get LEDs engineered for reef lighting rather than 6-7000k task lighting with some blues thrown in to drown them out.

Deciding on overall colour isn't as mysterious as some make it out to be. Just like MHL, you can have white, blue or half way between. You mentioned Phoenix 14000k bulbs, I would call them blue, as they are really 16000k compared to Ushio 14000k. You cannot make your lighting more blue or more white with dimming features. You cannot add, you can only subtract. This would be the same net effect as using a filter over a MHL light.

It sounds modular to be able to mix and match LEDs but to what end? Because of the limitations of product availability, drivers and optics, you are limited to colour changes only. Popping in one or two red or green LEDs will get you a few square inches of inappropriate light. It will not change what your corals get and will likely give you nuisance algae problems.

Most of the components and assembly of LED lighting is done in China and there is nothing we can do about that. What we can do is pick lighting products that are engineered for the aquarium industry and not a task light LED chip in a mass produced body with generic lenses, drivers and PCBs. This limits us to last years DIY technology.

Thank you Mr Wilson, very well said.

I ended up going with the Orphek PR-156 light for my aquarium. It was important to go with LED for the energy savings but I also wanted to make certain that I had a fixture that would stand the test of time. I think I went with the best choice. A lot of the decision was made on looking at the tanks posted on the net and seeing both lights in action. This pic shows what I am mainly talking about. I found it on a German forum. Didn't translate well but it's pretty self explanatory.
IMHO
1. There is a definite difference between the corals under the AI and the Orphek colorwise.
2. Stuff under Orphek has color and life, the AI stuff is dim and grayish/blue.
3. The AI lights appeared dim so I PM'd the owner and he told me that he had them at 100% and that's why he started looking, because he felt the AI were too dim. When he found Orphek he tried a few and has since switched entirely over.

I've never seen a more compelling product comparison pic the difference is unreal!

Can I ask what your association with Orphek is?

Where can us Canadian's source the Orphek lights?

Ive been a member at 3reef for a while now, Orphek the company is a sponsor on our site and is the best of all LED companies out there. They come on our forums all the time and answer any ones questions. They also have the best emitters for our hobby as well as being one of the few companies that makes their own bulbs specifically for reef systems. More than AI's use of cree. They dont dim because they dont need to, they built them right.

Marine Depot carries their stuff, they ship up here.

Orphek.com their canadian distributers is reefwholsalers i believe

reef wholesale is not their distributor unless it changed a couple weeks ago.

the only place that sells them online in Canada is GoReef out of Quebec.

You're making some very big claims. I'm sure you have a good reason for your biased opinion. When you refer to "our site", which site are you referring to? Which forums are "our forums"? I'm sure Orphek makes a good light but I have to call BS on your statement about dimming. Any reefer's goal is to replicate all of the conditions on a natural reef, and one thing is for certain dimming is a natural occurrence as the sun rises or sets. No it may not be as essential to coral growth as the light spectrum and intensity but I am sure it's a benefit to the coral. Southerner2 went off the deep end when someone mentioned dimming but the bottom line is when all things are equal with PAR and coverage, it is the bells and whistles like control features, ability to upgrade, and form factor that will seal the deal. IMO of course.
