Coolest Lamp Failure I’ve Ever Seen

My master electrician brought this to me yesterday – this is the most random, coolest lamp failure I have ever seen!  It looks to me to be a fingerprint failure, and once the envelope actually failed, the filament kinda puked itself out there, too!  The lamp was an EHD (120V, 500W) in a Kliegl fresnel.  Yes, a Kliegl fresnel.


Thomas Edison on Failure

I was just reading a great quote by Thomas Edison about failure.  There are several variations of this quote, but it’s just fantastic.  The backstory is that a reporter asked Thomas Edison about the thousands of experiments he went through to invent the carbon filament – something along the lines of “how does it feel to have failed two thousand times to create the electric filament?”

Thomas Edison replied:

I have not failed, not once.  I’ve discovered ten thousand ways that don’t work.
