Science Fair Project
Measuring the Brightness of an Incandescent Lightbulb
The purpose of this project was to determine the difference, if any, in
60 watt incandescent lightbulbs. All bulbs used in this experiment were ordinary, everyday lightbulbs. The experiment involved metering the amount of lumens given off by each.
My hypothesis was confirmed that each bulb varied in strength even though, all were rated at the same wattage. Each product was a nationally recognized name brand.
