   Has anyone seen these new fangled indoor halogen lamps?  They've been
   described to me: about 6 feet tall, point straight up (looking into one
   of them can ruin your eyes), take bulbs of up to 500 watts, light up a
   whole room well enough to read, with an analog dimmer to adjust the 
   amount of wattage used, use less energy to light a room than a regular
   incandescent bulb.

   I've been told that they are available by catalog and that some discount
   houses sell them for about $40.00.  


Local department stores (Boston area) sell them for ~ $100. Damark, among 
others, lists them in their catalog for $39.99 (extra bulb set for $12.99), 
shipping is $9.50. I bought two from them, and I've been using them since
mid-July, and I'm quite satisfied with them. At full power, 500 watts in a 
small room is quite overwhelming. It's almost a room heater at that level.
The dimmer is slightly noisy (AC hum). Damark is 1-800-729-9000.
The lamp is Item No. B-364-140905, for black. They also have 
white, brass, chrome and almond. UL Listed. 

Incidentally, the thing is really noisy, electrically. An oscilloscope about 
6 feet away from the lamp, when the lead is touched, shows the normal
background AC 60Hz noise. When the lamp is turned on, about one-fifth 
brightness, there is a glitch at every zero crossing. Quite noticeable, 
easily 10% - 20% or more of the sine wave peak. Are they allowed to put out so
much junk ? I turn the lamp off and use a regular (=non dimmer) lamp
when I'm taking any low voltage readings. I don't know if the noise
is being radiated, or put onto the AC line, or both.
