Weird experience with incandescent light bulb plus....

I dont know what to tell you about the plants since I am new to plants
too, but you electrical problem sounds like you have a corroded
connection somewheres. It could be in your light socket(where the light
bulb screws in(Most likley)), or another connection in the lamp wiring.
A corroded connection would give higher resistance at that point and
that increases heat. I have seen bad connections in the past bring on
untimely deaths to light bulbs. Hope this helps.

Thanks Chuckles! What you said gives me something to look for in the
future possibly. In this instance however I am pretty much 100% sure
that what I experienced is thermal shock to the light bulb causing a
thin crack to appear in each one. I am currently on my fourth bulb and
two of the others definitely had cracks on them near the base of the
screw in socket. The glass at the base got hot and the glass on the
rest of it stayed cool - thermal shock (carefully heat a piece of
glass hot and drop it into cool water to see for yourself). The only
question now is why did the fluorescent screw in bulb only last for
only 2 months. I think my tube fluorescent light bulbs/tubes have been
worn out for a long time and the screw in fluorescent worked so good
(except for the limited life) that I didn't notice how weak the light
from the tubes were. Either that or I just got spoiled by the screw in
fluorescent light bulb being so bright and penetrating. Thanks and I
will be on the lookout for what you described. Later - Dan!

The screw in base probably has a little corrosion on it(possibly from
being close to the water). I would suggest either changing it, or for a
quick fix, get some sandpaper and sand the inside of the socket base.
Of course you want to unplug it first but I am sure you know that .
The higher the wattage, the more heat is built up in the socket, so a
lower watt bulb like your screw in flourescent could possibly last
longer. I am guessing that your flourescent blubs are using less
wattage. Good luck and hope that helps.
