Fluorescent light bulbs are all the rage. Today, the majority of households in the U.S. have begun to adapt their lighting, exchanging inefficient incandescent light bulbs for energy-saving compact fluorescent lamps (CFLs). These familiar spiral-shaped light bulbs hide under our lamp shades, within our ceiling lights, behind our wall sconces, and are quite pleasant to use. Often, you can’t even tell the difference between a classic incandescent and a CFL.
As incandescent lights become a thing of the past, and energy efficient lighting becomes more of a priority, the fluorescent lights have gained popularity.
Fluorescent lights use much less energy to produce the same light output as any incandescent lamp, and they last many times longer. Plus, improvements in fluorescent lighting technology have turned these lamps into a pleasant source to have around your home or work space. The cost upfront isn’t terribly more than an incandescent, either.
Presently, cost and technology make fluorescent lights and LEDs (light emitting diodes) rivals in the energy efficient lighting market. But it won’t stay that way for long. Lighting experts say that while fluorescent lighting technology has reached its peak, LEDs are still evolving and improving. Even now, manufacturers are coming out with new LED lights that surpass fluorescent technology in many different ways.
Let’s examine how fluorescent light bulbs compare with today’s LED light bulbs:
- Efficiency: While both light sources are considered efficient, LED lights have pulled ahead. A CFL produces 30-50 lumens or light per watt, while an LED on the market today can produce 60-100+ lumens per watt.
- Rated Life: LEDs and fluorescent lights also both have long rated lives, but again, LEDs win. A CFL can last between 6,000 and 15,000 hours. An LED can last between 25,000 and 60,000 hours.
- Mercury: Fluorescent lights contain mercury, and LEDs don’t. While operating fluorescent lights on a daily basis won’t put you in danger, a broken light bulb will expose you to a small amount of this toxic substance.
- Infrared and UV: LED light bulbs don’t emit infrared or UV radiation in the same direction they emit light, but fluorescent lights do. Thus, LEDs will not damage sensitive material, and they won’t attract bugs. (more…)
