LEDs - Good, Bad or just another addiction?

[rafal07013]

anyway - enjoy aquaillumination that you have

I dont remember saying judge based on the human eye:

Your words:

I have seen both 1 w and 3 w fixtures and no matter how you look at it, the 3 watt IMO much closer replicate the natural suns rays.

so you are part owner of pacific sun ?

Possible Special Guest

Joe Yaiullo, Co-Founder of Atlantis Marine World, and President of LIRA just told me that world reknowned reef aquaria designer Jeff Turner will possibly come with him tonight. Here is a link to Jeff's website,

http://www.reefaquariadesign.com/

In addition to Acan Lighting, I have a good collection of aquarium LED lighting from around the world for you to play with, the brands include

Solaris I4
EproAqua
Thorntex
AI (Aqua Illumination)

I hope my office can become the information center for aquarium LED lighting.

See you tonight, and no fighting in my office, please.


James

My office will open this Friday, March 5 between 6pm and 10pm for all visitors who are interested in LED lightings. Everyone (including vendors) is welcome to bring your LED lightings for demonstration. A free 18" LED lighting (model A101) from www.acanlighting.com will be given to the draw winner.

Here is one of the tanks in my office, more than 80% of the corals in the tank have been grown from frags strictly under LED lightings since Dec. 2007.

I have a good collections of LED lightings around the world, and you are welcome to play with them. My office locates at "75 Austin Blvd., Commack, NY 11725" and serves as the monthly meeting place for Long Island Reef Association. There is no official LIRA meeting or auction this Friday, but all visitors are welcome to bring your corals and equipments for swap or trade.

See you Friday.

Cali, I'm still having trouble understanding your point which brings me to the point that you are just trying to start with everyone.

Yes, I do try to start with all 3,228 members that are registered here, specially the ones I dislike (maybe less since some poeple shill under multiple user names) :groupflip

I ask you again, what is your point?!? Where are you going with this? Or are you just trying slander and mock people like you always do?

Here is the definition of slander I don't think anything I posted is a slander to you or pacific sun (in a sense of law or your interpretations may be of). I do like to mock people, especially the ones that is trying to make a buck using any means. How is the vodka dosing coming along? I heard it's the best thing ever happened in reefing :lol2:..

I asked fairly technical points about all things I am interested in, I go on the offensive when the response is "lame" and the answerer tries to divert the question by attacking the question or person. I don't have a problem with your product, I think it's pretty cool from what Pecan's true and honest post tells, the problem is honesty and sincerity on the way you are "selling" it.

 

[rafal07013]

thank you for making it clear that you got nothing against the product but it is personal. at least know everyone knows why you posted what you posted.

I don't have a problem with your product, I think it's pretty cool from what Pecan's true and honest post tells, the problem is honesty and sincerity on the way you are "selling" it.

 

[AlohaTropics]

And what exactly is your problem when it comes to way it's being sold? I have to once again ask you, what is the point behind what you are saying? If you have a problem with something, then tell me what it is? Is it the patent law? You have a problem with Us trying to circumvent it? What about all the other led fixtures? Give me a clue what it us your so intent on arguing about here because up to now, your point is still unknown and it really looks like you are just trying to start a fight. I mean, first it was the patent law, then it was my explanation, then it was the infrastructure of the corporations, now you bring up a post from a year ago when I was very much an advocate of vodka dosing. What is it you are trying to say?

I have been honest and open with answering your questions. You somehow have to make a statement that my honest explanation of how we have interpreted the patent law is Lame. And now you are insinuating that there is something shady about the way we are selling. Where is this dishonesty you see?

We have spent a grueling amount of time and energy to even make this product available in the US. Everyone is delighted with the lamps and WE are taking all of the risk in bringing it in. We have done nothing but try to market a wonderful product that otherwise would be very hard to get in the US. We have spent countless hours troubleshooting and honoring the warranty which otherwise would be unavailable. What is it that you have such a problem with that we are doing?

I agree and I will drop this. Cali, you have such a problem with me, come give me a visit. Otherwise, i'm sorry Warren for hijacking this thread for a few pages. I invite the mods to remove our comments.

Alrighty then.............

So back to LEDs:
I had the opportunity to view the Eco-Lamp brought in by Acan Lighting today. It is definitely a sleek sexy fixture and looked very well built. These are probably the thinnest fixtures I have ever seen. These fixtures were over two separate 175g bowfronts and also over a pair of 92g corner tanks. the majority were A102 or KR92 lamps but there was an A101 or KR91 over one of the 92g tank. James from Acan Lighting had strung up two 18" fixtures and one 24" fixture for the 6 foot tanks and coverage looked good. I believe I heard that the A102 lamps utilize 50 degree focal optics and the A101 fixtures are raw LEDs with the standard 120 degree light spread. What was unknown to me was that both lamps have the ability to simulate sunrise/sunset by ramping up intensity of the blues & whites either separately or together. You can set the photo period for hourly such as 1 or 2 hour sunrise, but not in minutes. You still cannot control the intensity of the whites or blues so kelvin manipulation is not possible to color correct to your liking. The moonlight phase in this fixture is probably one of the best that I have seen in light fixtures in terms of visual appearance. It is better then my Pacific Sun and Solaris moonlight phases. Nice eerie glow and plenty of shadowing at the same time.
There are a lot of pros & cons for all the different LED fixtures out there in the market and you as an individual will need to do a lot of research & networking with present owners to see what your priorities are for an LED light and what you can live with in terms of the lower aspects of the light.
I loved the moonlight phase and the sleek sexy body of the Acan Lamp but I also love that my Pacific Sun's can adjust kelvin temps also. Alright so maybe I don't really need a "lunar phase" for my moonlights but being able to control intensity for acclimating new SPS frags is also priceless. In a nutshell, each lamp has it's strong points. The A102 were listed for $600 per foot and I saw 18", 24", 36" & 48" length fixtures. The A101 were much less per foot and I want to say $300 but honestly do not remember.
I also saw the V2 Aqua Illuminations module at James's place today and it's a bright light but really not my cup of tea. Very white light even when I had the lamp set to 70% whites & 100% blues. For the cost, they have a very basic controller and you would definitely want to run these modules with the Profilux for full access to the lamp's abilities.

now this is what i consider a useful post...informative and insightful. even though somewhat subjective but as far as we can see, it's truthful and has no hidden agenda. for those of us who were not able to be there, warren's descriptions and opinions are as good as being there. and that's good enough for me. thanks warren.

 

[duke62]

and he only had the 24" on his 92 gallon with plenty of light cover.so if you do have lets say a 48" tank 36" will cover at a height i believe was 6" of the tank

 

[AlohaTropics]

you been hijacking this thread to sell your light

Nope, my only involvement was to answer cali's question about the patent issue with orbitel. That's when all of the confrontation began.

I agreed. Each light has their goods and bad. The most IMPORTANT key is to understand their ups and downs and choose the APPROPRIATE one for your own conditions such as tank size, tank height, financial conditions and visual preferrence and your inclination to technologies or such.


Here is some rough data taken at last night's meet.
One member thought I was trying to bash Acan Light, let me explain to you that you are mistakened or jump to conclusion too quick. I was merely taking the data for a member who has a 24" deep tank and asked me to take the data to show him how it fares in HIS CONDITIONS. It turns out, the Acan 102 4' is not a good choice for him WHEN RUNNING FROM LEFT TO RIGHT, but with two 102 2' when lined up from front to back will be an excellent choice for him. Mind everyone, one 4' Acan 102 is same priced as two Acan 102 2'. That is, we should not jump to conclusion just by hearing ONE negative comment or a positive comment. While running the Acan Lighting 102 from left to right, it is not optimal for 24 deep tank when your aquascape is a rock wall leaning against the back wall. However, if your aquascape is an island type, it will work quite well. It's also an excellent choice for 18" deep tank when running from left to right.

All in all, we need to consider a LED in a more spatial dimension than just 2 dimensional(from the top to the bottom vertically.)

To answer the person who asked what's the PAR of a 400W MH at similar height, Please refer the second pdf of 90Reefernyc

Please check the pdf included. Any question, I am happy to discuss.
Note that the two numbers 64(at height of 26") and 122(at height of 32"). Once again, at a certain height/degree angle), higher PAR is obtained at more height than the less height when it's at the front glass or the back wall. This is very important factor where you should consider placing your corals when using LED.

I also took some data from the AI but unfortunately I forgot to write them down.

 

[aznt1217]

As if I didn't have enough addictions....

 

[duke62]

aznt what kind of lights are those.where did u get them and the cost.do u know the PAR reading on them and what corals are you planning on keeping with those

 

[Ziggy]

This are Pacific sun light. I just got my today after weeks of waiting all I can say is: it was worded to wait,will post some pics soon!
