I wonder what they are doing. I looked at the web page, but all I found 
was they are using a high intensity system. All of the lights in my shop 
are fluorescents (22 8', 75 watt tubes), or 1650 watts. If they were 
incandescents I could heat the place with them, but I'd need one whale 
of an airconditioner in the summer.
With the conventional fluorescents I have no RF hash, but they are 
sometimes noisy as in an audible noise.
