LED vs CFL vs Incandescent vs Fluorescent: Which Shines Cleanest? CFL bulbs, on the other hand, are made of glass tubes filled with gas and a small amount of mercury. The amount is so small that an old-fashioned glass thermometer holds 100 times as much mercury as one CFL bulb.he mercury in a CFL bulb also means that you should not toss burned-out bulbs in the trash. Many municipalities offer recycling services, as do retailers such as Home Depot, Wal-Mart and IKEA, although not necessarily at all locations.

- Bill takes apart an incandescent light bulb to how the filament is made. He shows extreme close-ups of the filament, and he discusses the materials processing need to make the ductile tungsten used.

- So for example if you are looking for replacing a 60w incandescent bulb than the right CFL bulb will need to be a 15 watt bulb. While the math for the CFL bulbs is simple, the LED bulbs are even more energy-efficient and more durable than compact fluorescent light bulb.LED requires less wattage than CFL for the same amount of light.hile the math for the CFL bulbs is simple, the LED bulbs are even more energy-efficient and more durable than compact fluorescent light bulb.

Types of Light Sources and Light Bulbs Compact Fluorescent Lamps (CFLs) are small fluorescent bulbs that can be used in most types of lighting fixtures. The screw-in types can be used to replace incandescent lamps in standard lamp sockets. T8 bulbs with electronic ballasts are commonly used in larger ceiling fixtures.

Light Bulbs Compact fluorescents, also known as CFLs, provide as much light as regular incandescent bulbs while using just one-fourth of the energy. For example, a 15-watt compact fluorescent light bulb yields the same amount of light as a 60-watt incandescent bulb.

Longevity of light bulbs and how to make them last longer For example, if you use a higher wattage CFL in any sort of closed fixture the heat that is generated by the light bulb becomes trapped in the can and will overheat the ballast and making it last up to 70% less than declared!

Compact fluorescent lamp Dimmable CFLs are not a 100% replacement for incandescent fixtures that are dimmed for mood scenes such as wall sconces in a dining area. Below the 20% limit, the lamp may remain at 20% or flicker or the starter circuitry may stop and restart. Above 80%, the bulb may operate at 100%. CFL has a higher purchase price than an incandescent lamp, but can save over five times its purchase price in electricity costs over the lamp's lifetime. Like all fluorescent lamps, CFLs contain toxic mercury which complicates their disposal.

Accidentally Breaking a CFL - Is It Mayhem? Maine DEP investigators monitored the levels of elemental mercury in the air when CFLs were broken in a room with a floor area of 11 feet 4 inches x 12 feet 1 inch, and a 10-foot ceiling — a room similar in size to the average bedroom.

The Status of Energy Efficient Lighting The electricity used over the lifetime of a single incandescent bulb costs 5 to 10 times the original purchase price of the bulb itself. Light Emitting Diode (LED) and Compact Fluorescent Lights (CFL) bulbs have revolutionized energy-efficient lighting. CFLs are simply miniature versions of full-sized fluorescents.

Light Bulb Types for Recessed Lighting Halogen light bulbs are a type of incandescent lamp. The difference is that the filament inside the lamp is enclosed in a small quartz capsule which contains a halogen gas. Halogen lamps burn brighter (and hotter), and last longer than traditional incandescent bulbs.his made it impossible to use an energy-efficient fluorescent light bulb in a standard (non-fluorescent) light fixture. To solve this problem, manufacturers began offering CFL lamps with miniature built-in ballasts and standard screw bases which allowed the bulb to be used in any standard fixture.

How Light Emitting Diodes Work Where incandescent lights last an average of around 1,000 hours, CFLs can last 8,000 hours. Unfortunately, CFLs contain toxic mercury that makes them potentially hazardous and a pain to dispose of [source: Design Recyle Inc]. Enter the LED light bulb.

Addressing Fears About LED Light Bulbs Sorry to hear that! However, my column was about LED lights, not compact fluorescent light bulbs. Compact flourescents are basically curlicue tubes filled with gas that lights up. LED bulbs use tiny light-emitting diodes, of the type you have seen in some flashlights and the “flashes” of smartphones.

- The dangerous part of a CFL is the electronic circuit. Some of them may cause short-cicuit and blow up on your face. If you use it as a table lamp them UV radiation is also a concern. Light emission diodes are expensive but safe.

LED FAQs LEDs are notable for being extremely long-lasting products. Many LEDs have a rated life of up to 50,000 hours. This is approximately 50 times longer than a typical incandescent, 20-25 times longer than a typical halogen, and 8-10 times longer than a typical CFL.Used 12 hours a day, a 50,000 bulb will last more than 11 years.

Accidentally Breaking a CFL - Is It Mayhem? Many people seem to think that when a CFL is switched on, all the mercury contained in that CFL is in vapor form. For example, if the average CFL contains 4 mg of elemental mercury (as was the case in 2007), they assume that when the lamp is switched on, 4 mg of mercury is in vapor form in the lamp. They further assume that if the lamp is broken while it is on, 4 mg of mercury will be released into the atmosphere.

Q&A: Why are incandescent bulbs being phased out? CFLs, LEDs and some halogen bulbs meet the standard, traditional incandescents do not. So come January 1, the phase out begins with 100-watt incandescent bulbs, when they can no longer be made or imported but can be sold until supplies run out. The 75-watt fades away in 2013, and a year later it’s good-bye to 60- and 40-watt incancescent bulbs. California began its phase out last January, Europe and Australia in 2009. To find the right energy-saving bulbs for your sockets, see our Ratings of CFLs, LEDs and halogen bulbs.

These Light Bulbs Cause Anxiety and Migraines. If You Have Them Do This Immediately For one, CFLs contain mercury, which is a major concern considering that many people dispose of their spent bulbs in landfills, which can lead to air and water pollution. When broken, these bulbs release 20 times the maximum acceptable mercury concentration.

- The Chemistry Of Light Bulbs Everyday light bulbs rely not only on simple materials but on esoteric ions and compounds. And while we take their product, visible light, for granted, the inner workings of these deceivingly simple gadgets depend on the complex behaviour of electrons. Let’s consider three types of light bulbs. The light bulb of the short-lived variety, is the standard tungsten incandescent bulb. Inside the glass, electricity flows through a thin filament of the element tungsten (chemical symbol, W, for its old name wolfram). Because the wire is so thin, resistance is high, and it raises the temperature of the tungsten wire, so chosen because of its high melting point of 3410 oC. At the bulb’s

Shopping for Light Bulbs Newer bulbs — like halogen incandescents, CFLs and LEDs — last longer and use less energy than traditional incandescent bulbs, saving you money on your energy bills. In fact, beginning in 2012, everyday light bulbs have to meet new Department of Energy standards for how much energy they use.

How to Recycle Light Bulbs Compact fluorescent lamp ( CFL ) bulbs are extremely energy-efficient light bulbs. These bulbs can save both money and power over incandescent light bulbs. Similar to fluorescent light bulbs, CFLs create illumination by heating a gas, which separates them from halogen or incandescent bulbs.

Units of Measurement Only 10% of energy in a light bulb is used to create light. Ninety percent of a light bulb’s energy creates heat. Compact fluorescent light bulbs (CFLs), on the other hand, use about 80% less electricity than conventional bulbs and last up to 12 times as long.
