Re: First post: Fluorescent lighting



Re: Efficiency
     It would be very instructive to make comparative measurements
of light output vs power input for various ballasting schemes.  I
would be very much interested to see if the high-frequency excitation
really increases the net light output, at the same power input.  The
easiest way to make this test would be to set up each configuration,
use a light meter at some convenient distance, and measure light
meter readings vs readings of a wattmeter at the input to the device,
either conventional lamp or power supply for high-frequency exciter.
