Compact fluorescent (cfl) bulbs provide about four times as much visible light for a given amount of energy
ise. for example, a 14 watt cfl bulb provides about the same amount of visible light as a 60-watt incandescen
bulb. led lights are even more efficient at turning electrical energy into visible light. does that mean they are
both a lot hotter? go online and research how fluorescent and compact fluorescent bulbs work. describe how
heir operations and their spectra differ from those of incandescent light bulbs. be sure to record your research
