I bought my first LED bulb for the house, at a sustainable energy fair , for $40.00 which is comparable to online prices. It’s a 6W bulb that gives the equivalent light to a 50W incandescent. These bulbs are rated for something like 60,000 hours, should last me a while… This particular light gets turned on a lot, since its in a corner over the dining table where the only window is heavily blocked by trees (the one area in the house not well lit with daylight). Also my wife often complained that the previous lamp was too bright and felt like an operating theater, so its the perfect place to try it out. The payback will be… at 16c a kWh… actually only about 4 years which is not too bad.
On the left, the lit lamp shows a few of the individual LED bulbs glowing. On the right, unlit, it is much like a conventional incandescent bulb
