A few more great uses for LED lighting: defense against zombie attacks!

 While we have talked about LED primarily in the efficiency sense, it seems to me that another great use for LED lighting is defense against zombie attacks!

Ben fighting the good fight in Night of the Living Dead

Well, mind control may be a good tool.  The New York Times blogged about this lately, how LED lighting can be used to interfere with melatonin the hormone secreted from the pineal gland linked to sleepyness.  Brings to mind the movie “From Beyond” by HP Lovecraft the mastermind behind Re-animator  where scientists stimulated the pineal gland and opened up a parallel universe. Horrors for sure, link clickers beware.  On second thought mind control might not work on zombies.

The CDC has put out the very useful guide how to survive a zombie apocalypse, but I might add a few tools.  For one, weapons aren’t mentioned much, and I have to say very important but really a last resort grab whatever you can. 

If stranded in a farmhouse under attack, I’d want to stand beside my hero, Ben from Night of the Living Dead (played by Duane Jones a former English professor and the first African American actor portrayed as the hero in a horror film, for that matter cast in a major motion picture when the role did not specify the part had to be played by a black actor).  Ben grabbed whatever he could, and since they only had a single shot gun, the biggest problem was keeping the zombies out.  

And since I’m venturing in wild speculation, it just may be that now there is a way.  The new scientist reported a company has developed something that will come in handy in the event of a zombie apocalypse,  fingerprint activated locks.  This company Dermalog Identification Systems in Hamburg, Germany while not intending to defend us from zombie attack seems to have the perfect device.  Here’s why: Apparently their sensors check to see how a finger reacts to being scanned. Living tissue blanches or changes color being that the blood is squeezed out of capillaries when its pushes on a surface.  

From the article:     living fingers absorbed LED light at 550 nanometres on first contact and then at 1450 nanometres as the skin blanched when fully contacting the sensor (Forensic Science International, DOI: 10.1016/j.forsciint.2011.05.014).

Dead fingers don’t.

Of course, if the zombies simply claw through the door, we’re right back where we started.

LED lights to the rescue, who cares about efficiency?  On second thought, I think I’m staying inside for the 31st, locks already ordered.  But I can spend that day switching to LED lighting for other reasons and (hopefully!!) leave the zombie control to someone else.

Happy Halloween!
