LED light bulbs?
At one point in the past, I was running all CFL bulbs. However, I really dislike the color of CFLs, and some of my light fixtures caused CFLs to buzz. I really enjoy GE Reveal incandescent bulbs, so I switched back. Recently, I took the plunge to switch to LED bulbs. I’m using Philips AmbientLED bulbs that have a color temperature very close to incandescent bulbs but use about 20% of the electricty. The higher end bulbs are dimmable and make no buzzing sound in any of my lamps. I went from 520 watts to 90 watts for lighting the office by switching. Unfortunately, the bulbs are not cheap, but I should break even in about 10 months.
