Minimalistic multichip DIY LED build

[TropTrea]

That said, are the standard 20K chips a mix of whites and blues as well?

This will vary considerably by the brand of chip your getting. The 20,000K light to be true 20,000K is primarly blue with only a small amount of white. The closest to a pure white would be a 5,000K chip with a 100% CRI. if you put one of these chips in with 4 Royal Blues you would have a 20,000K effect. however it is possible to make a single 20,000K chip. The only problem with it would be that the demand would be very limited to aquarium industry. This limited demand would push the price upward. It is cheaper to make a million of something compared to 10,000.

I used ELN60-48P x 5 for my build I currently have mine limited to 500ma/channel and started the light at 20% white / 30% blue on PWM control.. I forget if I measured the current at the 20/30% level but it's not a whole lot... 150ma at 20% I think. 11% PWM is the lowest it will light up at - I forget the current but it's pretty low. Setting the current limit lower does decrease the power at minimum too. Sometimes I wish I'd set it to 350ma max current but it's a fair bit of work.

Whats is your idea of ​​the dream chip so far? Do you have the same experience as me? Since starting as carefully as you do, I assume that you have corals in the aquarium. Are you satisfied with the colour rendering?

I have a 12k 50w on my 27g cube and it's almost perfect, if there was just a touch more blue it would be what I want to look at

a 2:1 white:blue ratio would probably be what I want, but these still single color and hybrid still lack the uv/red that the dreamchip gives, and the adjustability

At the moment there is no invidual red LED´s in the Dream Chip´s configuration.

Where did you get the dream Chip, I looked on ac-rc's Ebay store and could not find the Chip.

ISMANU...

You will not find it on AC-RCs store.

The information is being presented here under the guise that it is being openly developed by a like minded group of "experts" and for the betterment of the "community". When in fact much of the dialog is carefully worded to shill for an under-the-radar for profit business venture disguised as a community project with R&D paid for by the community but to be credited to one or two individuals, if not fatten their wallets. If this is up your alley, then you should be able to find the product by searching for it.

I wouldn't say it runs that deep, but yes the chip is a shill for a group buy until it is sold individually to the public.

 

[megadeth72]

hopefully it's sold to the public soon

I have seen other multichip multichannel leds but not marketed or designed for reef use

These are grave accusations. They are, among others, aimed at me.
Where I come from, it is not acceptable to post this kind of accusation without a shred of evidence. It is also not acceptable to accuse others of confidence trick without any evidence.

Not in any post either here or elsewhere have anybody called himself an expert - nor has anyone attempted to lure someone else in a project to benefit himself. On the contrary - both I and the other driving force behind this project has been repeatedly pointed out both strengths and weaknesses of this project.

[ISMANU]

Thanks for the reply Bean that is the info I was looking for and in that case not really something I was looking for. I am just doing as much research as I can while I try to decide how I want to light my 250 build

Lets not pretend our feelings are hurt and a noble cause has been sullied. The "dream chip" project is very clearly a side business, not a group buy with zero profit, done for the noble reason of advancing the hobby.

I like it so far - everything looks at least as good as it did before the switch. It took some time to get used to the lack of disco lights but I much prefer this setup. Previously I had a fixture with a 60w 4100k citizen emitter surrounded by 26x3w 445nm blues and 8x3w 420nm. Even with the emitters spaced as closely as possible the disco was terrible.

The corals don't seem to have noticed - everything is doing well and growing. The orange cap monti is a noticeably darker shade of orange.

Yes it is clearly a side business, although I think not for whom you are implying. I don't believe ac-rc is a member of reef central, and it is obviously his business. I'm certain he is making a profit - that's usually the point of a business venture. Is there something wrong with making a profit on work done and goods sold?

I don't think anyone except you have referred to this project as a noble cause - it's always been clear that the purpose was to get a particular product to people who wanted it, and to report back how it was working.

I'm really tired of your attitude/trolling towards the subject of this thread, however irrelevant that may be.

This is my 2 x 50watt multiled DIY Project..
I am using a Computer Fan/temp Controller wich uses a build-in Loud buzzer.
Buzzer start beeping when fan stop working or temp rises

Could you please advise what controller you are using?
Thanks!

But I have never seen a white light as crispy as this before. It is better than I dreamed of. Several reefers here in Sweden that have started their Dream Chips has the same impressions.

Same here, I'm driving all the channels at 700mA and fellow reefers couldn't believe how crisp the light is.

My only "problem" is that I prefer my tank to have more blue color, so I will probably lower the power for the white channels when I install the second chip which is still waiting for me to do it.

Lasse, would you say from your experience - is there any difference if I lower both white channels simultaneously, or lower one more than another? Any reason not to lower them the same?

Nice try, but lets drop the silly games, shall we? The role of AC-RC or their profit motive is not relevant and not "who" I was refering to, but you already know that.

Secondly, I don't begrudge anybody turning a profit. In fact, I love to see mom and pop businesses make money. What does bother me is a side business being promoted as a not for profit "group buy" that is promoted by shills who knowingly game the rules. What about the folks who DO follow the rules and have spent THEIR OWN money developing a product, but are barred from promoting it here?

I have no say here and am only stating my opinion, something that is relevant to this thread. I may not agree with some of your opinions and/or the manner in which the "dream chip" is being developed and promoted, but that does not make me a troll.

i support you and the group buy 100% without things like this we would never move forward in this hobby. ive never heard anyone associated with it claim that it was non profit. some people have other opinions obviously.

Except group buys cannot be done here, shilling is highly frowned upon, and there is no reason to have to sell the thing in a group buy instead of individual sale. The whole thing is beyond shady.

Funny thing is, it isn't even optimal. You're stuck with one choice of how the channels are laid out, because that is how a few people organized it based on how they wanted it, without even seeing it or testing it before it shipped.

There isn't much visible blue light in the dream chip so dimming the whites won't make it much bluer. The 16k is bluer than the 10k but neither offer much blue.

Without seeing the chip myself, I would estimate the colour temperature to be about 10k with all channels at 100%. Dimming the whites will make it look a little more violet.

I prefer a crisp white light myself, but like most people, I enjoy blue fluorescence for a few hours at night.

I do not know what you is up to or where you have got your fantasies from.

Neither me or any other person involved in the Dream Chip configuration and construction has earn any money on this. We do not have any rights to it and will not earn any money in the future if it will be a success. The only one here earning any money and has the possibilities to develop this concept in the future is the vendor from Hong Kong.

The only thing that makes us do this is what tomservo mentioned. We were a few persons that want a chip like this and the way to make it happen was to openly describe the project and involve other people.

You suggest other purposes and if you plan to continue with these hints, you are free to express your evidence. I would love to see them so I know how much money I will earn in the future and above all - my wife wants to know!

If you are going to acuse anyone then state clearly whom you mean or else there might be misinterpretations and the worng people might feel accused.

As far as I know there is no one making money out this group buy but ac-rc and their manufacturer. So I'm really intrested in knowing who you mean since I have bought a lot of these chips.

You can't just go around making loose accusations based on your opinion, that's just rude. So present your proof.
