Just after I got married I bought two 75 Watt long life 120 Volt "Krypton"
lamps for my new front
porch lamp as it was a pain to change. (at $5 each) The first lasted 1/2 an
hour, thinking it was
a "juvenile failure" I installed the second, which lasted 1/2 an hour. I got
out my VOM and
measured 135 Volts, after that I was particular to never pay more than 9 Cents
each for a lamp.
(Canadian GE's) The next day the live voltage was normal.
