LED Lighting Retrofit and News Blog - LifeSpec

I was curious about the basic economic breakdown of replacing a typical 60 watt incandescent household light bulb with an LED equivalent.  I used the Home Depot website to gather information on a standard household 60 watt “soft white” incandescent light bulb, and an LED replacement for such a bulb.  For this comparison I looked at the GE 60-Watt Reveal A19 General Purpose Incandescent Light Bulb, and the Philips Ambient LED 12-Watt (60W) LED A19 Light Bulb (E).  Both bulbs are what would be considered for normal household use in table lamps, bathroom lights, porch lights, etc and have the same “soft white” light appearance.   The basic assumptions I used for this comparison are taken from the information provided on each bulb on the Home Depot website, and include the expected bulb life, energy cost, and average hours of use per day.

Interesting LED Use: Treat Acne

Here is an interesting use of LEDs other than for normal lighting needs: clear up your acne!  According to the Tanda Company, 414nm blue LED light has been proven to kill acne-causing bacteria by producing oxygen singlets.  These singlets have a phototoxic effect on key porphorins, and attach to the acne causing bacteria causing them to self-destruct.  The Tanda ZAP acne spot treatment device utilizes this technology, and sells on the company website for $49.

LED Lights Create Constellations in London

No, that ring of what looks like stars is not in fact a new constellation or alien UFO. That ring constellation is actually a man-made attempt to recreate the night sky despite living in modern day society where major cities are lit up 24/7 with street lamps, high rises and automobiles. That light pollution drowns out the dark night sky and stars are less visible compared to an open field in the countryside.  To reconnect the urban city dwellers of London with the stars, French artist Oscar Lhermitte came up with the “Urban Stargazing” project.


By using solar powered LED lights, nylon lines, fiber optic cables and telescopic catapults, Lhermitte and his team have created 12 constellations (some original, some recreations of the actual thing).  

Suspended between tree tops, the urban constellations can be seen by the naked eye during the night in 12 different London locations.  What better instrument for this project than some LED lights. The high level of brightness, longlasting, low power consumption and small stature make LED's the perfect tool for the job. Check out a few of Lhermitte's original constellations below and see how he transforms LED technology into art.

German engineering is typically known for their luxury automobiles but at the Festival of Lights (aka The Lichternacht) in Solingen, Germany, the Guiness World Record for largest flashlight was awarded to LED Lenser's 13 foot long flashlight.  The Optimus Prime sized flashlight utilizes 19 high powered LED lights that produce 100,000 lumens or 30,000 on batteries.  The Guiness World Record was completely shattered with the previous record holder being a mere 7 feet long.  Check out the video after the jump...

As we always say, give people some free time and some LED lights and strange things happen. Like using LED lights to grow ummm....medicine.

A very useful property of LED lights that make them highly efficient grow lights are the fact that LEDs come in a rainbow of spectrum and it’s easy to focus on particular spectrum that plants need to grow (red and blue). In addition, the fact that LED give off a very concentrated bright lights give high performance for minimal energy use.

Apparently an entire subculture of LED grow lights have popped up and being embraced by indoor horticulturalists. Here in California, horticulture tends to be code for “medicine” that patients need to cope with cataracts, arthritis, or a boring Saturday evening.
