While driving around this morning, I noticed a few LED arrarys in traffic lights that are dying: one red light, and two green lights. Each light has patches that were dark, and patches that were flickering at various states of brightness.
Besides wondering what the heck is causing these LEDs to die in this way (could it be a ban on lead solder?), these lights have caused me to ask another question: Is LED lighting really ready to take the place of incandescents?
I currently rent my home, and both finances and space are tight for me. Thus, stockpiling incandescent lights are impractical at this moment. I hate fluorescent lights, so I have hopes that LEDs will be ready and affordable after incandescent lights are banned. And while I expect that the Free Market will win in the end, we, unfortunately do not have a Free Market--as illustrated by the ban of incandescent light bulbs.
But seeing these lights flicker have caused me to wonder: will the LED lights really last as long as claimed? We already know that fluorescent lights don't--turning them on and off like we do incandescents are abusive to those lights, as is putting them in enclosures and in ceiling fans.
We really should let the Free Market work these details out!
