An LED light bulb that glows as if it was an incandescent light bulb with a filament, and illuminates like one as well. Delivers light equivalent to that of a 40-W incandescent light bulb, but with a rated lifespan of 40,000 hours. Designed for use in standard light fixtures, including those that are enclosed. The addition of a 40-W-type product to the original 20-W-type will further encourage the changeover to LED from incandescent light bulbs.
