2 Fluorescent lights Glass tube filled with Mercury Low Pressure Phosphorus substance inside tubeElectric current runs through:Gets HotGlowsElectrons hit Mercury atoms which produce UV lightSaves Energy
3 LED LightsProduce light by having an electronic current pass through the material with illuminates the lightHas different colorsPopular because its very efficient
4 Incandescent lights Most common lights used in homes AKA “screw-in A type light bulb”Most inefficient light bulbLight bulbs with thicker filaments:Last longerNot energy efficient
5 Halogen lights They are the energy-saving incandescent lights More expensive to buy than incandescent lightsLess expensive to run than incandescent lights (Due to its efficacy)Has color renditionsOften used in lamps
6 The Compact Fluorescent Bulb Most efficient lightThe Compact Fluorescent Bulb
7 Environmental Concerns Incandescent lights:Use too much heatLED lights:Contain too much MercuryCFL:Most efficientDon’t use too much heatNo mercury
