Crazy Looking Light Bulbs


Compact fluorescent lamps (CFL) are designed to replace incandescent (standard) lamps and here’s why they will be a big success:

·         The integrated lamps combine the tube and ballast in a single unit allowing consumers to easily replace incandescent lights.

·         Their service life is estimated to be 6,000 to 15,000 hours and a standard bulb has a life of only 750 to 1,000 hours.

·         The energy efficiency (rated in lumens per watt) are 50 to 70 compared to incandescent lights at 10 to 17. 

·         Though the cost of a CFL is typically 3 to 10 times more than an equivalent incandescent bulb, CFLs last 8 to 15 times longer.

So far the only drawback is that like all fluorescent lamps, CFLs contain mercury (in the form of a vapor) which is toxic.  Most CFLs have 3 to 5 mg per bulb with those labeled “eco-friendly” containing as little as 1 mg.  In the U.S., the National Electrical Manufacturers Association have voluntarily capped the amount of mercury per CFL.
