Okay, I'm jumping in here to help out Rafal on this topic. First of all for One Timer, The LEDs are rated to go for at the very least 5 years before they will lose any potency. If you were to replace individual lights at that time, it would be very inexpensive to purchase. Its very hard to say because unlike MH and T5's, these units are not MEANT to have bulbs replaced. You can, but it will be like trying to put together a vintage car. Rather, in 5 years time, LED technology will have improved soooooo much that you would more than likely buy a new fixture. Who knows, maybe we will offer an upgraded PCB board that can be easily installed and Viola! Brand new LEDs in the fixture. My point being, these units are not meant for switching out individual bulbs. If you wanted your unit to last forever and ever, you could do it buy just purchasing 1W LED bulbs and DIY replace them...shouldn't be too difficult.

NOW, you are putting Rafal in a tough position. I realize that other manufacturer's are proudly displaying the CREE LED as a component. The LED lighting industry is changing pretty rapidly. What was once the best LEDs a few years ago, is not today. On top of that, the aquarium industry is seeing an influx of LED lighting from cheap manufacturers to upper tier like PacificSun. What separates us? One major factor is the bulbs we use. It takes a lot of time, money, and studies to decided which is the best bulb to go with when producing these lights. You should see how many tanks needed to be setup side by side with the same corals and each with a differnent board of LEDs. It was a ridiculous sight to see but it needed to be done to really document the growth and response to different manufactured bulbs. There were tanks were the entire stock died in a matter days! The right combination of UV bulbs with different UV intensities all down...I mean we are talking about a lot of test tanks setup....EXPENSIVE RESEARCH to find the right light combination. Unfortunately, with the amount of copycats out on the market who benefit off of the research done by others, this is why certain component parts are kept secret. The wrong LEDs in a unit will wipe out your entire tank. So when we have the right chemistry between bulb types, light spectrum, power, controllability, etc... it becomes propietary to protect our investment in the design.

That being said, we are NOT using cheap LEDs and CREE is NOT the only brand out there that makes good LEDs...and not all fixtures use only 1 kind of LED in their makeup...many hints in there. Our fixtures have been tested and tested and show amazing coral response as you can see from the Feedback thread. And they will only get better as we continue to work on creating a better product everyday with research.

I also want to add that the bulb choice is not only for coral health because most photosynthetic light spectrum is invisible to the human eye. Its also a degree of finding the aesthics in the specrum of lights for viewing purposes. So the proprietary blend of lights is one of the key ingredients in a successful fixture.

Felix,

Thought I had a valid question, not to put anyone on the spot. But to allow potential buyers to see the value of the system. That is why I am buying one- I was able to see the light in action and believe that the product is superior to any on the market! The innovative software will not be obsolete in five years that is why I was curious to see if the manufacture had taking into account the ability to replace the board so that if needed it could be done.

Rafal has been a great help and should be commended for fielding the numerous questions regarding the product. Seeing is believing when making this leap in innovation so I will gladly open my doors and allow anyone on this site the ability to come to my house and see the set up and play with the software- just bring a six pack!

the way it was presented to us - there are 3 things that can go wrong inside the lamp:

a) fans
b) leds (leds, heatsink etc)
c) controller

all these parts easily taken apart and put together. spare parts available in US.

Hi Rich,

Sorry about the confusion in the response. The first paragraph was in response to your replacement question. The next paragraph was directed towards putting Rafal on the spot about the actual make of the LED bulbs we use. So your question was a valid one.

Dude

It was just a legit question that wasn't answered the first time it was asked so I followed up with the same question, If the answer is that it is a proprietary company secret then so be it, but say it as well, don't just ignore the question. Man, you have to calm down, It's within reason to ask questions about a product and get a reasonable answer. There is no doubt that R & D is costly and lengthy and that Pacific Sun has gone through great lengths to bring this product to the public and formula to their success is proprietary then say it, don't ignore the question.

I did not mean to put Rafal on the spot that was not my intention and if I did I apologize.

Hello,yeterday I had put on my 4 lamps.
I am happy with them but I have one question, why do the fan run in the night, when the light is off?
Can I change the parameters off the fan?
Thanks a lot,
Pictures will come tomorow.
Robert

Fans are spinning permanently due to uProcesor algorithm. Only thing you can do is set fans speed to 0 RPM - they wont work at night, but at daytime they wont work also till time the led matrix temperature will reach the value you set in PC program. Then fans will start, and run with maximum speed.

I'am still working on new software, that fix this, and a few more problems.

Lesek,
Is this also true for the 1st Pythons that we received in the US?
Should we set our fans to 0 RPM or leave the fan speed set at 255 RPM which defaults to 100 RPM after the values are read (if set to 220 RPM, it defaults to 65 RPM, if set to 100 RPM, you will get an error message)

If you say that fan speed is okay to be set at 0 RPM, what should the normal and maximum temp setting be?

Thanks,
Waren

I must check it on your version of software, but as I remember the Pythons you have in US, has the same fans algorithm. Let's explain it with an example.

if we set "fan settings" like this:

Default Fan speed = 0
Normal Temp = 35*C
Maximum Temp = 40*C

Critical Temp = 45*C - this parameter is invisible for user. 45*C is set as constans value in uP memory.

ok, lets mark Led Matrix temperature as "T"

when T > 0*C and T < Normal Temp, fans will not spin because we set speed to 0, if we set speed to other walue, fans will spin with that value of speed.

when T > Normal Temp and T< Maximum Temp, fans will spin at almost maximum avaiable speed - tryiung to lower led matrix temperature.

when T > Maximum temp and T< Critical temp, fans will spin at maximum avaiable speed - it means that temperature still is rising and going to be dangerous

when T> Critical Temp, fans will spin at maximum, and LEDs power will be lowered to 50% - because of led overheating protection.

So, you see the settings can be different for any user. Everyone has different temprature of air in apartament, over the aquarium etc. You can set fans as you like, but led matrix is stiil safe (T_critical is calculated and constans)

Anyway, this algoritm will be replaced with more dynamic procedure. Fan speed will be more adaptive, more dynamic in next wersion of software. I am still working on it.

Thanks Lezek.
I tried the settings that you had mentioned and yes, the fan will stop if the internal temperature is less then the normal temp setting.

Only problem is that when you set the default fan speed to 0 RPM, you cannot read the lamp values after connecting via bluetooth. There is an error message.
