They are also more expensive than incandescent bulbs. However, they last so much longer they will more than pay for themselves over the long run. Another downside is that CFL bulbs contain a small amount of mercury which can be released if it breaks or is disposed of improperly. Even with the mercury each bulb contains, the EPA says CFL bulbs still help reduce mercury emissions in the United States because of significant energy savings. \u00a0They reduce the demand for electricity, which reduces the amount of coal burned by power plants, which reduces emissions of mercury when the coal is burned.<\/p>\n<p>There are specific cleanup instructions if a bulb containing mercury should happen to break. These include airing the room out, specific\u00a0materials to clean up and dispose of the broken bulb. Visit the <a href=\"https:\/\/www.epa.gov\/cfl\/cleaning-broken-cfl#qi\" target=\"_blank\">EPA website<\/a>\u00a0in order to find out the complete instructions for cleaning up a broken CFL bulb. It is important to recycle used CFLs, also. Recycling prevents the release of mercury into the environment. Most of the materials in fluorescent bulbs are recyclable and can be reused. Many states and local jurisdictions have regulations about disposal of CFL bulbs, so be sure to check your local regulations. Visit the <a href=\"https:\/\/www.epa.gov\/cfl\/recycling-and-disposal-cfls\" target=\"_blank\">EPA recycling webpage<\/a> for more information.<\/p>\n<p>Think a CFL bulb is too harsh, too white and way too bright? Many new CFL bulbs are designed to mimic the yellowy light of an incandescent bulb. There are now silicone covered CFL bulbs which give off a softer, more pleasant glow.<\/p>\n<figure id=\"attachment_5282\" aria-describedby=\"caption-attachment-5282\" style=\"width: 133px\" class=\"wp-caption alignright\"><a href=\"https:\/\/blog.lib.uiowa.edu\/eng\/files\/2017\/02\/Halogen_Vehicle.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-5282\" src=\"https:\/\/blog.lib.uiowa.edu\/eng\/files\/2017\/02\/Halogen_Vehicle.jpg\" width=\"133\" height=\"133\" srcset=\"https:\/\/blog.lib.uiowa.edu\/eng\/files\/2017\/02\/Halogen_Vehicle.jpg 750w, https:\/\/blog.lib.uiowa.edu\/eng\/files\/2017\/02\/Halogen_Vehicle-150x150.jpg 150w, https:\/\/blog.lib.uiowa.edu\/eng\/files\/2017\/02\/Halogen_Vehicle-300x300.jpg 300w, https:\/\/blog.lib.uiowa.edu\/eng\/files\/2017\/02\/Halogen_Vehicle-36x36.jpg 36w, https:\/\/blog.lib.uiowa.edu\/eng\/files\/2017\/02\/Halogen_Vehicle-115x115.jpg 115w\" sizes=\"(max-width: 133px) 100vw, 133px\" \/><\/a><figcaption id=\"caption-attachment-5282\" class=\"wp-caption-text\">Philips WhiteVision Halogen Headlight Bulb<\/figcaption><\/figure>\n<p>&nbsp;<\/p>\n<p>A Halogen bulb &#8211; or a &#8220;tungsten-halogen filament incandescent bulb&#8221; &#8211; contains a small capsule of halogen gas, which provides a bright white light.
