"Contrast this to fluorescent lights. At six inches from the source, you'll be receiving about 700 foot-candles."

With not only incident light meters, but typical garden foot-candle meters, I've never had lower than 1,200 foot candles from T5HO Fluorescent one foot from any T5Ho light, banked or individual.

And the highest I've seen is 2,500 foot candles from the same distance in laboratory conditions.
