You have a Switch LED Lightbulb with the following information: It is equivalent to a 40 Watt incandescent lightbulb. It uses 8 Watts of electricity. It is estimated to last 25,000 hours. It is dimmable. It produces 450 lumens of light. It has a color temperature of 2,700K (warm white). Based on this information, calculate the lighting efficiency of this bulb and determine whether this is more or less efficient than a traditional incandescent lightbulb.
56 lumens/Watt, less efficient
56 lumens/Watt, more efficient
0.0178 lumens/Watt, less efficient
0.0178 lumens/Watt, more efficient
