Current halogen living room lamps are 300 watt type, which (if you have 2 of them) burns 600 watts (that's almost have the amount of a small heater). I like LED replacement bulbs for standard outlets, but can't find one for halogen floor lamps, so this would use LEDs to illuminate the living room, for
a fraction of the cost.

||When you say cost, do you mean total cost including how much 'leccy you'll save over the lifetime of the lamp, or how much it costs to buy one?
||Many of the large torchierre types intended to light a room with a single one are 300W. Of course it is already possible to buy identical lamps with fluorescent tubes. I'm not sure about LED yet, as the economical LED bulbs tend to be for low volume point lighting at this point.
||my heater burns at 1500W; the bulbs in my lamp are 300W each (there are others at lower watts, but this is what mine has); I'm looking for something drastically less, not just a little less
