Recessed energy saving tip.
The LED Retro Kit fits almost every standard 6" housing (will not fit a shallow housing), uses an input of 0.127 AMPS/14 Watts, Color Temp 3000K (an incandescent lamps color temp is 2700K), and a lamp life of 50,000 maintenance free hours(averagelifeofan incandescent is 4000 hrs and a CFL of 10,000 hrs) . And best of all, it is dimmable to less that 10% (with a Lutron or Leviton Electronic Low Voltage Dimmer).
Simple installation, quiet, no RF interference and NO MERCURY. The retro kit I use comes from a major on line/catalog supplier of commercial lighting and cost in the neighborhood of $50.00
