LED light bulbs that I got from Home Depot. This is the "Definity" A19 LED lamp by Lighting Science Group and is sold under Home Depot's in-house "Ecosmart" brand as the LED Bright White A-19 lamp. Uses 8.6 watts to produce about the equivalent of a 40 watt incandescent bulb or 429 lumens. The package says this has a 3000K color temperature which is a little whiter than the common 2700K "warm white" most compact fluorescent lamps but it is pretty spot on to an incandescent bulb (In fact, it could actually be mistaken for a 40 watt inside frost incandescent bulb). Efficiency would be about the same as a compact fluorescent bulb at 50 lumens per watt but this has the benefits of hitting full brightness instantly, being dimmable, and for those paranoid people; does not contain mercury like fluorescent lamps do. (Some LEDs do contain arsenic though) It's still expensive at .47 each though but then, compact fluorescent bulbs used to also cost that much when they were first available. The price, however, is a lot better than the to for LED bulbs with similar light output performance. Until now, most of the LED bulbs I've seen below only gave out 1/3 the light output of this and were better suited as a nightlight or decorative lighting vs lighting up a room. I still have to see what longevity would be like before deciding if LED lighting is ready for "Prime Time" but for now, light output, color temperature, and pricing has met my expectations.
