Pros: cfl; long average use
Cons: getting used to the color of the light; initial investment
these bulbs are great from an eco and, in the long-run, financial perspective. very long average use rate (about 5,000 hours), meaning i won't be replacing this bulb for many years! this obviously saves $$ in the long run, but it's worth noting that it takes a heftier initial investment (costs around $20 for the bulb if you buy it online). also, the light is "natural spectrum" meaning more bluish than conventional bulbs. this is supposed to reduce strain on your eyes. i like working with it, but it's a bit odd because when you turn it on in a room otherwise "conventionally-lit," it looks kind of weird.
