The article compares CFL and LED lamps in terms of their performance and efficiency. The researchers conducted laboratory tests on different lamps from various manufacturers to measure their electrical characteristics and photometric properties. The goal was to determine how these lamps impact the power grid and their brightness levels. LED lamps are newer and more energy-efficient than CFL lamps, but manufacturers are working to make them more cost-effective. Key findings include differences in luminance, luminous flux, and luminous efficiency between the two types of lamps.
