Works as advertised. I think it's a great deal even though it's more expensive than an incandescent or incandescent bulb. LED bulbs last longer, emit adequate lumens and heat up less than traditional bulbs. A lamp's wattage, while proportional to brightness, is a measure of energy output. An LED bulb that puts out the same lumen count as a 100 watt bulb uses about 1/10th the energy (current) compared to an incandescent bulb. My experience with 3-way bulbs has shown them to last for several months. My experience so far is that LED bulbs last much longer. In fact, I haven't had a single failure yet and some for several years.
