switch out the soon to be scarce incandescent bulbs with fluorescent or LED bulbs.  there is now a lower wattage bulb for every old incandescent need.  the market has exploded in the last few years.  look hard enough and you can find the warm, dim-able, non buzzing and low watt bulb of your dreams.  errr… am i the only one dreaming about light bulbs?  huh.

in any case, this watt conversion kit always comes in handy:

happy bulb changing!
