Pros and Cons of LED and Fluorescent Tubes
To give recognition where it's due, fluorescent tubes are a great invention. They have been lighting most of America ever since GE brought them to market back in 1938. They are four to six times more energy efficient than incandescent bulbs and are said to last 10 to 20 times longer. Of course there are disadvantages too.
Fluorescent tubes contain mercury and phosphor which present health and environmental risks. Lights require a ballast which adds to the cost of the lamp and can cause a buzzing noise. Finally, they flicker and the light is often drab.
Meanwhile, dimmable led tube last longer than fluorescents, they don't contain harmful ingredients like mercury and they use much less power than fluorescent lamps. And this is just for starters. LEDs aren't perfect though. The tubes are generally not as bright and cost more up front. And unfortunately, cost will likely be the number one driver of greater adoption. So let's compare the costs of each.
The debate over LED vs fluorescent tubes always teeters at the cost argument. When comparing the upfront cost of one LED tube to one fluorescent tube, fluorescent wins. However, when you consider volume discounts and the lifespan of LEDs, the scale leans the opposite direction. Let's compare the costs of each.
A Bright Future for LED Tubes
The cost of manufacturing LEDs by led tube light manufacturers is dropping. Researchers at Purdue University have developed a way to create LEDs using inexpensive, metal-coated silicon wafers instead of expensive sapphire-based bulbs. This has the potential to bring the cost down to levels competitive with fluorescent tubes. You can stay up to date on news of this development over at the Eartheasy blog.
In the meantime, there's no reason electrical contractors shouldn't promote LED tubes. LED tubes can help building owners become eligible for government and utility company incentives. They help companies reach the desirable – and highly marketable – green cachet. They provide greater energy cost savings than fluorescents. And finally, they are simply better for the Earth. They are the future of commercial lighting.
