Blue LED Light Bulbs: A Nobel Prize-Worthy Invention



LED light bulbs

For those of you who still feel that LED light bulbs haven’t come far enough to be of any use, the Nobel Assembly would like to note that this year’s Nobel Prize for Physics has been awarded to the guys who invented blue LEDs, which are what makes LED light bulbs possible.

You’re probably wondering why that matters or why you should care. That’s fair. The reasons are many, but what it boils down to is that physicists around the world pretty much all agree that this is the greatest invention of the last 20 years – hence the award.

Blue LEDs: Kind of a Big Deal  

LED light bulbs may still be trailing the pack for residential use in the wake of 2014’s Incandescent Light Bulb Ban as halogen and compact fluorescent lights make gains, but their impact has been rippling through global societies and economies ever since professors Isamu Akasaki, Hiroshi Amano and Shuji Nakamura invented the bulbs in the 1990s.

American consumers are most familiar with LEDs as they are used in energy-efficient home lighting and the screens of their electronic devices, but large-scale use for water sterilization, greenhouses and cheap lighting are more far-reaching.

The Nobel Assembly’s white paper on the topic highlighted the significant of the blue LED and how it allowed for combination with other already available colored diodes to make white light, thereby unleashing a cascade of energy-saving possibilities. For scientists with vision, LEDs are the answer to global resource depletion – cheap, long-lasting light for all.

The Residential LED Revolution

Residential LED light bulbs carry the undeserved stigma of their history and development like an albatross around the proverbial neck, but that’s about to change. Yes, it’s true that for the longest time LEDs were not available in variable spectrums and were too expensive, but now their spectrums vary as much as any other type of bulb (thanks to these Nobel Prize winners right here) and their price vs. cost savings over time are literally impossible to beat.

What’s more, it’s the belief of the Nobel Assembly and a whole bunch of other scientists that this is just the beginning of a full-on LED revolution. There are currently at least a billion people – a billion – who live without a regular, affordable light source and LED light bulbs could change that. That equates to more safety, more productivity and an overall healthier world – all because LED light bulbs can last longer and produce more light with far less energy than conventional bulbs.

LED Light Bulbs: Just a Matter of Time

Of course, Americans are often not the earliest adopters of new technology, especially when corporate lobbyists with more interest in bottom lines than energy savings work to keep consumers in the dark (zing!) about how great LED light bulbs really are. This, of course, has had an impact on the pace of development, but as with hybrid technology and solar power, the pendulum will eventually swing in favor of the LED bulb.

But, you don’t have to wait! You can start saving money and the planet by finding clever ways to use LED light bulbs.

Bulbrite''s dimmable LED light bulb comes in soft and warm white, is rated for 25,000 hours and only uses 12 watts of power to create lumens equivalent to 60-watt bulbs. 

This dimmable LED bulb from Feit Electric is rated for 30,000 hours (approx. 27 years of regular use) and provides lumens equivalent to 90 watts using only 20 watts of power.
