Thanks, I'll forward the link to reefbuilders and see if they need pics.

1) You don't have to worry about any patent infringement if you're just building your own fixture, only if you're manufacturing and selling it. DIY'ers are safe.

2) There are a number of problems with LED systems, they are too expensive, they are more complicated than the average system, and they are yet to be proven as a sustainable and effective alternative to existing products for the average reef keeper. No matter how you look at it LEDs are low power which makes them less practical for this industry. I see great potential in residential lighting if the cost can be reduced but not so much in our hobby, well except for moon lights.

3) LED is just a new idea and popular as a result of marketing more than anything else. In five years something else will be out that's far better, even as we speak there are better things on the horizon.
1. Yes, technically they could sue you but it would not make economic sense to spend tens of thousands of dollars on lawyers to recover a few thousand dollars in damages so in practice no DIYer would have a problem. However, it could endanger companies that sell DIY kits or parts to aquarists such as nanocustoms etc.

2. The only problem with LED systems at the moment is cost. And that is really an up front cost as the long term costs are probably less over 5 to 8 years when you look at lower energy consumption, less heat added to the tank so probably less chance of needing a chiller or other cooling mechanism for your tank and the elimination of bulb costs compared to MH or other systems where you change bulbs every 8 months to a year depending on what you're running. So if you actually do the math the overall costs of an LED system are probably lower, just all up front instead of over time.

3. LEDs are not just marketing but an advanced and energy efficient lighting source that, if done right, can accommodate any lighting needs you have from a cheaper fish only lighting fixture to a high PAR fixture for corals. There has been plenty of experience now with LEDs and lots of testing to show that they can produce as much or more PAR as any HM setup. In fact, some testing shows that the light is more tightly contained if using optics and the fall off of PAR as you go deeper in the tank is more linear with LEDs than with MH. that means that if you compare a MH to an LED setup that have the same PAR at the surface of the tank, you will likely have higher PAR at the bottom with LEDs than with MH. Many examples of great SPS colour and growth are out there too. Just check out some tanks on nano-reef.com or at reefcentral that run LEDs.

So what's the issue? Are you looking to build and market LED fixtures and retro fits? If not I would let the people that want to worry about that. I assure you there is always a way around patents like this, monopolies only last so long. This type of thing happens all the time but competition always finds a way if there is potential market share available.

However I don't see much potential. I have never seen an LED system alone support an average size tank with mostly SPS corals. You could with the same reasoning stack a ton of NO florescence over one tank in hopes of it meeting the demands but it simply won't work.
I don't believe the intensity is there, simple as that. Yes they are efficient and very cool with all the programing options but that's it. The cost is not why these lights are not popular, if they worked as well as you say then more people would use them but unfortunately no one has really proven these to work as suggested. I offer the same challenge to you, very simple just present a tank that proves me wrong.

If they did work as well as the alternative I for one would use them, I love efficiency but it still needs to work. I spend plenty of money on good equipment that works well and is efficient.

These are quite the LED tanks... I'm sure the LED setups weren't cheap at all, but sure does look like the tanks are doing well..










Now, I certainly am not an LED advocate, just thought I would post a few LED tanks to stir up discussion.

Those don't support LED potential in my books, first one has no sign of any high light demanding corals and that fixture has 400 LEDS which is at least 400Ws, if that's a 6 foot tank then I think 10 36" T5 bulbs would be brighter.
The second tank is too short, if you want to prove the potential of LEDs we need to see them setup on an average size tank which is clearly a 90 gallon and 2 feet deep. That tank also seems to have gotten a lot brighter in the second pic and the fixture is conveniently out of frame

the biggest problem is finding the stuff for a reasonable price. for example it is going to cost me about 600 bucks give or take to build the set up for my 30 gal tank, Ron is about 1200 for his tank.

money waise for me this is still not back concidering two 250 watt MH over the same tank would cost about 600 to get going also. the differance is I should get about 10 years of use from my system with no more money added. two MH on a 30 gal will definatly need a chiller, so there is another 600 bucks, then two bulbs a year for 10 years is another 2K. and if the calculations are right I will have over 400 PAR on the bottom of my tank wich is about inline with 250 watt DE MH. so I will have the same par output but only consume 200 watts of power instead of 500. and no heat issues as all the heat is disapated through the heat sink up into the air. then to top it all off I will be able to dim each color seperatly so I can get any color temp I want for the tank, and if I spend another couple hundred bucks I can put togeather a digital controler to slowly fade in the colors to different degrees at different times of the day and fade out again at sunset. since I will be running two white controlers and two blue, if I gwet some new frags, I can drop the intensity on one side of the tank where the new corals are and slowly bring it back up over a week or so to get the frags used to the light. features you just cant buy in systems that are out there right now.

Like I said the company could sue, but would they, no.. like I said and Ron said the cost is against it. it would be like metalica sueing the 20K people that downloaded there music, they wouldn't have sued 50 people, but if there are enough people to make the lawsuit worth itin the end then ya.

the reason we want the patent squashed is to encourage compatition. this would bring the overall cost of LEDs down making it cheeper to build. also it would allow bigger lighting companies the creat system. for instance if PFO would have been entering a market at the same time as 4 other lighting companies with the solaris, you can bet it would have been about 500 to 1K cheeper. Also it would open the doors for compinies to produce retrofit kits. right now the market is limited to people who can figure out resisters, electronic soldering, drilling and tapping, and you have to source the parts from about 4 different places.. heatsink from one, led's and drivers from another.. thermal paste from another, ect. So LEDs right now are only feasable to a slice of the reefing comunity than has the knowlage and skill sets to build them.

The issue is that this patent is going to harm the growth of LED lighting and innovation. Most small aquarium lighting companies will not want to pay royalties to Orbitec and it's a dodgy patent in many people's opinion. If Orbitec gets the continuation allowed they will be able to control all aquarium LED lighting except for moonlights. I don't think that will be a good thing for the hobby.

it is pretty well established now that LEDs are a viable alternative to other types of light. i don't have time to hunt for lots of information but here's two quick links that show what some people are seeing with LEDs:

http://www.ultimatereef.net/forums/s...d.php?t=321387

http://www.reefcentral.com/forums/sh....php?t=1639666

And yes, the intensity is there. Don't try to look directly into a high power LED. Way bright. Lot's of PAR readings too and people bleaching and and killing corals with LEDs out there.

I am planning on starting my 48" LED array build soon so you will all see what it does on my 75 gallon mixed reef.

One simple sticker on your proposed LED fixture would solve the whole patent issue.

" NOT FOR AQUARIUM USE"

I see a fantastic potential for LED lighting. Many reefers are tired of the static though beautiful SPS tanks and are looking to LPS coral which offer the opportunity to view florescense that LED deep blue lighting provides. The difference is colour is shocking.
The newer LED systems provide this opportunity. You can focus light beams, programme different lighting and dim which is not available on dated MH lighting.
I would encourage the lighting experts on this board to experiment with DIY and bought systems.
I am defineately not knowledgeable of the details of LED but IMO LED is the future.

Yes I've seen some nice thanks that use LEDs as supplemental to halides and/or T5s. LEDs can create the spotlight effect which is very nice. I agree and see potential as supplemental but not so much on their own. I see more potential in the plasma light than LED, the plasma is 1000x smaller and more efficient. The other problem is LEDs is limited spectrum.
