Tj25C it's realistic,in my opinion, only if you run softly in active cooling setup... More interesting data,I completely agree, the situation from Tj35C to max Tj50C, not Tc. Very interesting COB of course,I'm very interested to see possible model, maybe to test on spectra-lamp, but they need...

nice work as always stardustsailor....and welcome back!!! realy interesting consideration....thanks for sharing.... preliminary, the most obvious think that it gets ... that there is more experimentation in RIU and more advance knowledge in this forum .... that at NASA lab..... thank you SDS....

Italian politics is bad and absurd, are two years that is being discussed medical use and yet there is no real regulation, and people with rights in reality can not use it. Maybe it happens dear PSUAGRO, could create jobs, and also cover much of the public debt of our country. But for now, 60...

Thank you Abiqua! for you as obvious, as for all professional RIU users , always special offers...;)

in my opinion, I think also interesting the possibility to calculate the 1.2A result for V29 and CXA/CXB 3070 thank you for your hard work!

congratulation nice work with excellent growth potential! realy appreciate! thank you for your work!

Thank you Eraserhead i appreciate a lot! Actually are objects that have been studied and simulated accurately for a long time, improved revision after revision, and are actually realy "machines of light". We push the COB9 to 1350 watt...I have see incredible number...and incredible result! their...

Ciao PSUAGRO... I want to thank you really for your appreciation. Is strange that someone said that, is not true obviously, however, we are not a big company, we are a small design studio and our lifeblood is the passion. We are engaged on "several fronts", but we continuing every day to work on...

thank you...yes it is very good ... always DIY oriented ... and you can customize the spectrum ... is very useful for experimentation, with only a careful selection of Luxeon Rebel top BIN, and I guarantee you it's amazing what can be able to do...I have developed a spectrum that works very well...

thank you very much Positivity...I appreciate your words, this is the result of many sacrifices and hard work... then, I do not expect that everyone will understand how difficult it is .... those working in design and engineering know what I mean....

I'm involved in the project
