Forgot .. definitely the blue peak is in the visible side; when speaking circadian rythms, corals etc. .. the peak at 440 nm is very common in the marine aquarium industry; the term "blue shifted" spectrum is actually common I would say. But green drives more energy so it gets mixed a bit as...

Hi Tom, Thank you very much for the reply. Greatly appreciated it. If time permits I will structure the calculator in such a way that is shareable as open source; so it can be dissecated and commented out by the forum. I am sorry, I didnt confirm that the image would be so blurry. later i...

Hi @Tom.G greatly appreciated your input. See below the reference for spectrum and energy of light pendant in use. This is a rack of 4 lights being tested out. so around 1200 Watt. for the area mentioned above it will be around 3 racks (3600 watt) Following your commment in terms of light we...

Hi Berkman, yes it will be geared towards the aquarium industry. The earlier thread I ended up doing all the calculation and ended up actually being good summary for all heat transfers; i could compute that into a calculator which was my initial goal so i am pretty happy with that (while...

Good morning, I was wondering if I am thinking correctly. I am trying to establishing some step by step to calculate the amount of energy is being absorbed by a water body when a LED pendant is shining right above. Being the parameter that I want to calculate, the energy absorbed by the...

Hi @Philip Koeck yes that is true; i am looking or trying to look past it as well so to compute in the losses or gain by conduction, convection and radiation and their role. I have all of that computed now. Evaporation is not linear to calculate in indoor situations when the surface is not...

Hi, I have been calculating a series of hypothesis for some aquariums/tanks situations, using heat transfer equations (conduction, convection, radiation, evaporation) Typically we have aquariums that run at higher temperatures than the surroundings in winter and lower temperature than the...
