I have a solar battery charger that shows the intensity of light.

on a sunny day the meter reads about 2 hours of light to charge here in san francisco

when the solar charge is inches away from the (600 hps) bulb, it goes off the charts.

at about 2 feet its about the same as if it were outside on a pretty day.
