Solar Simulators - Create Artificial Sunlight
I stumbled upon an interesting concept called 'Solar Simulators' aka the electric lamp that'd simulate the sunlight. I got some more information here: <a href="https://en.wikipedia.org/wiki/Solar_Simulator" target="_blank" rel="noopener noreferrer">Solar Simulator</a> , but now looking for some more information from those who've actually built one or have used it.
How does the thing work?
