Here's great news for anyone who has been waiting for LED lightbulb prices to drop from "oh my goodness" to "oh good, I can buy one". Best Buy's in-house brand is now offering the warm spectrum, Insignia LED bulb, both online and in-stores. Shaped just like a traditional incandescent, the bulb uses 75% less energy than a traditional bulb, with a product life of more than 22 years; the 60 watt equivalent 800 Lumens model costs just $1.57 to light up per year (three hours per day). A few notes after trying one below...Plugged into a table lamp our review unit illuminated with a light somewhere inbetween the warmth of a regular soft white filament bulb with a hint of bluer light characteristic of LEDs (the 800 Lumen bulb is rated as 3000K). Not a 100% match, but only noticeable because we compared them side by side, before and after using our remnant 60 watt incandescent kept around for these bulb comparisons.
Additionally, the Insignia bulb turned on instantly, working with our lamp's dimmer control without issue (some users on Best Buy's review site noted flickering, but this could be due to the quality of a home's power lines, something we've learned while living in an pre-1930's unit with plenty of plugged-in devices), and seems ideal for secondary table or corner lighting instead of as a reading light source. Now if they can only offer a sub-$20/bulb 100-watt equivalent, then I'd switch out all of our CFLs and convert our home into a fully LED illuminated apartment!
