The objections to using LED lights as replacements for standard light bulbs because they are inconvenient is suffering another setback with the GeoBulb II. In a lot of ways, from the overall shape of the bulb to the screw-in socket fitting, it looks very much like a standard incandescent light bulb. But the GeoBulb is anything but standard.
The GeoBulb is brighter than a conventional 60 watt incandescent bulb (381 lumens versus 337), but, at just 7.5 watts, uses only one-eighth of the electricity. It is designed for direct replacement of incandescent or other screw-in base bulbs.
The GeoBulb is still pricey. A brief search turns up a street price of around $100. You can certainly get a trunkload of incandescents for that price (but you’d pay a trunkload of money for the electricity to run those bulbs). The electricity savings is going to take years before the payback on this bulb is reached, but the manufacturers are offering a 3-year warranty on the bulb, even if it is left on 24/7 (which, with 10 cents per kilowatt-hour electricity, should be enough to justify the payback to get this bulb).
