LEDs - Good, Bad or just another addiction?

[rafal07013]

hey - as i said earlier - enjoy your aquaillumination. if you think your lights are so much better and replicate sun rays etc, etc - please post full shot of your tank so we can see it. After you post it, i will post links to nano-reef.pl where you will see tanks that have 1W for a long time and people will be able to see and make their own judgment.

dont be shy - post pics and lets see.

Based on the intensity of the fixtures and how much power they put out yes any 3w LED fixture will much better replicate the suns rays.

Im not shy.

Ill take some pics tommorow am and post them up.

Wheres your pics?


I have said over and over, Rafal you gotta read. I Said "ANY 3w LED fixture better replicate the sun."

I did say just AI i said any!

 

[Aqua Pro Builder]

.... Didn't someone said Chinese products are no good??

Luckily, I didn't say that. :biggrin:

I am made in China, Hong Kong to be exact. :groupflip

What controller you are using for the AI?

 

[rafal07013]

take it, post it - lets talk than. you got pics on NJREEFERS.org - feel free to post it what you have and see those nice and better sun arrays you are talking about.

lets see it and lets other people to judge it.

I understand comments made by Cali - b/c at least there is a little bit of logic to it (I think there will be some major annocument coming out soon about it) but you have AI so enjoy the light, enjoy the hobby - dont go and bash other products that you have not seen in person or used.

Ill take some pics tommorow am and post them up.

Rafal

why is this so personal for you?


I didnt bash the product i ask why they were using 3w leds. I got an explanation but you seem to keep getting very personal when people talk about pac sun.

You keep turning this into AI vs Pac sun when i have repeatedly said 3w vs 1w.

Wheres your pics Rafal?

I have seen the 1w fixtures and 3 w fixtures.

The pics i posted on NJ reefers are while the tank is being set up most of the stuff has been moved around and the lights adjusted to how i like them.

Wingo im using the one that came with the fixture at the moment. Im going with profilux as soon as i can.

 

[rafal07013]

it is not personal - you made claims about absolete product and better sun arrays - so i asked you to show it so people can see it and on the other hand offered to show you tanks that are using 1W in poland for long time.

still waiting - you got pics on other forum so show us your better sun arrays.

why is this so personal for you?

 

[Aqua Pro Builder]

Wingo im using the one that came with the fixture at the moment. Im going with profilux as soon as i can.

Once you do, please post comments. I want to know how you like it including "is there even a need" to use that controller when AI already has a controller build-in(unlike mine is only Profilux ready.) I tried the build-in one with Ai, and it kind of suook.

The dimmer dial pad of Epro Fixture is excellent but not programmable though.

 

[RARECLOWNSNJ]

Ok

I wanted to know Why PAcsun aka you and felix were coming out with a new fixture with 3w leds when you already had a 1w that was supposed to be good enough.

When a computer is made with more memory or a faster proccessor the old model is considered obselete. Which in aquarium stuff is true too. I didnt make this up, its widely know.

That doesnt mean that a product doesnt work it just means that there was a chance for upgrade.

In my pics on the other forum the lights the tank was just set up as i said and had lots of stuff floating in the water, cyano on the sand from my cycle. Its a mess but it was the first shots of my tank with the leds set up on them.

I GOT THE LIGHTS ON JAN 6 those pictures are from JAN 13. The tank was set up Dec 10.

Id like to show pics of what my tank looks like now, fully setup and the Leds totally adjusted. You can wait till tommorow cant you?

Ive never seen pics of your tanks with LEDS on them.

Rafal do you work for pacsun cause youve got all the answers.

 

[rafal07013]

RareclownNJ - can I ask you a question - does ONE 3W bulb produces more light than 3 1W bulbs? yes or no? yes, I do have the answer and it is not tricky question. any math/physics guys can help out.

 

[RARECLOWNSNJ]

Rafal

Wheres pictures of your tank and do you work for them?

This is what i mean man, how the hell do you know all this info if you do not somehow have insight to the making and marketing and set up of these fixtures.

You still dont speak to what i write you start a whole new discussion.

What is the different between 1W and 3W leds if we are talking about light spectrum?? - NONE. You can run the same led at 1 or 3W it depends only of amount of current and ability to take heat from led structure. For example cree leds - you can run it at 100, 350, 700, 1000 or even 1500mA. The same led is producing from 0.5 to more than 5W of power. But if we are talking about amount of light - consider that 3 leds at 1W are producing MORE light than one led at 3W.

This question is meaningless..

The question should be: Is three part number XXXX 1W LED "better" than one of part number XXXX 3W LED, given the same operating conditions?

Different brand and part number LED's have different efficiency, just because they CONSUME the same amount of power, don't mean they will produce the equivalent amount of light.

Can you provide some specific examples of your assumption? Are you saying you guys are running the 3W nominally rated LED's at 1W power and is better?

I thought the other person is talking about the sun ray effect, that is related to concentration of light in a given area rather than talking about the efficiency or the total light output.
One person is talking more about the look while another person is spinning it into more technical aspect of LED.

 

[rafal07013]

I have been following aquariumled.eu since beginning of 2009 on nano-reef.pl I have been in touch with owner since mid 2009 and even approached one of a vendors from MR to take a look at these lights back in July 2009 but that vendor had no interest.

I can speak and read Polish and do spend time on both polish forums where updates on these lights are pretty much 24/7.

also - not a secret - I am in touch with the guy who actually designed these lights and wrote the software. you want his email to have the same info? just PM me.

pics of my tank and entire PS thread dissapeared from RC 24hrs AFTER arzep pointed to Wingo that he took pics of leds from Alibaba and sells very similar light :wink1: and deletion was done by a guy from LI. I hope you can connect the dots.

I disagreed.


If you run a CREE that is capable of 350ma, 500ma, 700ma and such, base on color temperature chart I seen, color temperature varies and thus there must exist a change in spectrum. However, to general user, this is not very important because VISUALLY only noticeable when they are comparing the two extremes of very low current and very high current.

Yes you are right - this is what i wanted to say, but as you see iam not speaking english very well so sometime i have troubles with "words".

Can you provide some specific examples of your assumption? Are you saying you guys are running the 3W nominally rated LED's at 1W power and is better?

The problem is - most of all leds are "nominally" rated at 1W. Of course they may be powered with bigger current, but "the point of entry" is still 350mA (about 1W).

look for example at cree XPG datasheet. http://www.cree.com/products/pdf/XLampXP-G.pdf - page 5. They still marking 350mA as 100% of intensity.

Next, analysing chart on page5 you should reach the point that 3x1 is more light than 1x3

Wow, when did I become famous in RC??? I am hardly there. What was the thread about anyway?

Well you have had pictures up im sure it wouldnt be hard to repost them here like you have been asking me to do.
