How so? You can't reproduce the sun.

Actually...................

Let's read this quote first:

"Direct sunlight has a luminous efficacy of about 93 lumens per watt of radiant flux, which includes infrared, visible, and ultraviolet light. Bright sunlight provides illuminance of approximately 100,000 lux or lumens per square meter at the Earth's surface.".

Got this quote from ----> Sunlight

Ok so if the sun produces 100,000 lumens per square meter, at the Earths surface, one can conclude that if you can concentrate enough artificial light in a square meter, it would recreate the same amount of lumens that the sun would.... If you were to place 2 1k HPS watt lamps in a square meter, you would have 280,000 lumens available within 18" of the bulbs and would probably have 100k lumens within 4'......(forgot the formula of lumens x distance)....anyway....

Just saying that it is possible to recreate the brightness of the sun if you concentrated the light to an area....might not have the full light spectrum but will have the lumens....and no possible chance of clouds....
