Ok I'll try. I can mesure the iluminance of the light, in lux, (yes, I changed the way I mesure), so I use a resistor that gives a value that I useto get value of the iluminance. Now I have the luminance and I want to convert it into energy, or something that gives me the result in W/m^2...

Yes, I'm using and Arduin system that mesures the eletric current that the sun produces, then I use a table to convert it (actually I'm trying to make it give automatically the result in candela, buut I'm not very good at programming)

In candles

I need to know how much energy will I have for a certain intensity of ligh, I need this because I want to predict how much water will my solar oven evaporate for this light intesity (I can mesure the light intensity). I'd be very thankful if anyone helped me on this because I've searched a lot I...

Ok, thnak you very much

I was searching about the light and I found an article tha says that the light could have some kind of mass. This research was made at Harvard-MIT Center for Ultracold Atoms by Harvard Professor of Physics Mikhail Lukin and MIT Professor of Physics Vladan Vuletic and I don't know
