LED lighting and fluorescent lighting are just two of the types of lighting technologies available. Both have their own sets of advantages and disadvantages. One key area that they differ in is the area of energy consumption and lifespan. Comparing LED lighting and fluorescent lighting requires taking a look at a few key specifications.
Types
LED lights are light emitting diodes and are found either as single diodes, such as in a flashlight, or as a cluster of diodes to create a light bulb. Fluorescent lighting comes in two primary types: tube lighting and CFL (compact fluorescent lighting). Fluorescent lights can range in size from tubes multiple feet long to the compact bulbs that are about the size of a standard lamp light bulb.
Lifespan
LED lighting can last upwards of 60,000 hours before needing to be replaced. Fluorescent lighting, particularly CFL bulbs, can last around 10,000 hours before needing to be replaced. You would have to replace the average CFL bulb 6 times to equal the lifespan of one LED tube.
Lighting Ability
LED lighting is ideal for directional lighting. Directional lighting is useful in lights such as flashlights and desk lamps. The light focuses on where the bulb is pointed rather than bathing the wider area in light. LEDs are also found in vehicle headlights and electronic devices for status lights.
Fluorescent light bulbs are ideal for lighting up full rooms, with full-size tubes being ideal for large rooms such as warehouses where focused light is not needed. CFL bulbs are useful for home use and lighting up bedrooms and living areas.
Energy Consumption
LED light bulbs use about half the wattage of fluorescent lighting, about 6 watts of power versus 14 watts of power for a CFL light bulb. For an LED bulb's lifespan, about 340 kilowatt hours of electricity is used. CFL bulbs used over 60,000 hours (6 bulbs) will use around 840 kilowatt hours of electricity, according to the website Product Dose which compared different light bulb energy specifications.

LRC issues report on LED lighting for airfields
The Lighting Research Center at Rensselaer Polytechnic Institute has published a report to help guide airports as they consider LED lighting for various needs around an airfield.
The new report, "Issues with use of LED airfield lighting: ACRP synthesis 35," LED Downlight published by the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute, concludes that reduced maintenance cost is the primary benefit for airports considering a move to LED lighting in the airfield. Energy savings are secondary in part because airfield electrical systems are designed for incandescent loads.
The Transportation Research Board (TRB) of the National Academies published the LRC-authored report in conjunction with the Airport Cooperative Research Program (ACRP) which funded the study. The LRC has also long worked with the Federal Aviation Administration (FAA) on ways to take advantage of solid-state lighting (SSL) technology on airfields.
John Bullough, senior research scientist and adjunct professor at the LRC, authored the report. "LED airfield lighting uses much less energy than incandescent, but airfield electrical systems are optimized for incandescent lamps, not LEDs," said Bullough. "Even more energy can be saved if electrical systems are designed with the reduced loads of LEDs in mind."
Other findings of the report include the fact that the visibility and performance of LED lighting on airfields is generally good. LED Lamps Early on in the development of LED lighting there were what the report called "compatibility problems" with SSL and airfields but those have been overcome.
The research was based on detailed surveys of 22 airports and aviation agencies. The report speculates that despite high upfront costs, the installation of LEDs will generally payback in "several years." An upgrade of the electrical infrastructure can increase energy efficiency and reliability of airfield lighting systems. According to the LRC, LED Light for car the FAA is now investigating new infrastructures for airfield lighting.
