Is V2 the second configuration discussed on RC?
Ron, I still don't understand. What is the V2?
Just a reminder. Also posted in the 2nd post of this thread:
For successful long term usage of the Dream Chip or any other multchip LED panel, cooling is very important!
AC-RC recommends ~60C measured at the metal back plate.
If an idea or a design is publicly published, you cannot apply for a patent on it. This is why I have been quite detailed in my description.
These ideas are not something I neither want to nor can earn some money on, I'm only interested in getting as good light as possible to my saltwater aquarium.
At the same time, maybe the whole hobby gets a boost, which is good.
If it turns out that we thought right - I am absolutely convinced that we will have many different dream chips on the market rather soon.
The manufacturer should perhaps protect the name "Dream Chip" but that is his business.
I have got my chips now bur have to wait with the built cause I do not have any drivers just now. I have one driver that are able to give 1400 mA – some tests will I do.
The middle channel has a higher FV so those who plan to use one drive - take it carefully. Until someone has measured the reality - do not go over 5 A with one drive and all five channels in parallel.
@ronreef: I supose you meant that AC-RC recommends max 60 degree C on the back plate? If it cooler than that - it is not bad I think.
Sincerely Lasse
Ron, do you mean AC-RC is in the process of making a new/larger back plate to help with the Dream Chips 60C cooling that is recommended/needed?
Update. As posted in the second post of this thread:
For the buyer of multichip LED panels, be aware of non-genuine EPILED and EPISTAR LEDs. One sure fire way to tell the difference is by inspecting the surface morphology of the
LED itself. Each manufacturer has it's own signature surface design as seen below. If it looks nothing like what you see in photo below, it's probably not what you thought it was.
Ask your seller to provide proof before you purchase.
Ultimately, cooling any multichip LED panel is the responsibility of the end user. Whether it's a bigger cooler, more fans, faster fans, dialing down current, better thermal adhesive. It's a combination and balance of the aforementioned cooling concepts based on your reef tanks practical needs. I personally believe, the back plate size is good enough. It has more than enough real estate to provide excellent heat transfer given the heatsink contact area and the backplate make good solid full contact. There are many other factors to consider but good solid full contact is the place to start off with.

Thanks Ron,
That in essence, is what I thought you were referring to. So what are they improving on in this "next generation", that the original Dream Chip was lacking? I understand testing at 1.4A @ channel that the chip is rated to handle, so what are they actually trying to improve? I don't mean to be a pest, but just trying to understand.---Rick
