Question
Transcribed Image Text:You have a Switch LED Lightbulb with the
following information:
• It is equivalent to a 75 Watt incandescent
lightbulb.
• It uses 20 Watts of electricity.
• It is estimated to last 25,000 hours.
• It is dimmable.
• It produces 1,100 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.
0.018 lumens/Watt, more efficient
55 lumens/Watt, more efficient
0.018 lumens/Watt, less efficient
55 lumens/Watt, less efficient
