I replaced my front lamp post a few months ago. The new one uses a
standard light bulb (not the mini bulbs the previous fixture used).
Problem is, the wind shakes the post and my bulbs are only lasting about
a week. This was always a problem, but it's much worse with the larger
Are there bulbs that are made to withstand vibration?
As I understand. Fluorescents use a tiny filament to heat
the gas, and then the electricity goes through a heated gas.
So, with a CFL, it occurs to me to turn it on when the wind
is calm, and the post is steady. So you don't blow out the
heater filament. Same deal with your blast cabinet.
There are two types which I'm aware of. One is intended for drop lights, and
produces pretty ugly light compared with "normal" light bulbs. The other
type is labeled "ceiling fan bulbs". They're sold at Home Depot. I use the
40w version, and I'm not sure if they make larger ones for that purpose.
Light quality is good, and they do what they're designed for in terms of
resisting vibration. Assuming you're not trying to light up the yard like a
baseball stadium, they should do the trick.
Use a CFL, mine are going on 5 years now. When the temperature is
below zero, they take a while to warm up, but they do work at below
zero once they warm up.
Gotta be careful with some timers which will go belly up if they're
controlling a CFL bulb. Intermatics in-wall digital timers had this problem,
although the company was terrific about replacing them with updated
Yes, but they acheive it by having very heavy filiments that consume a
lot more power. For something like a lampost that is on for long
hours, that is a consideration. A CFL would probably be very good in
that application. Just allow 15 minutes or so to get to full
brightness in winter time. A CFL left on 24/7 might cost less to
operate than using a rough service incandescent.
Compact fluorescents are good for that and will work down to 0 degs.
F, unlike regular fluorescents. But if you need incandescents, look
for "rough service" bulbs, which have far more wire supports for the
filament than regular bulbs do. Auto parts stores may have them
cheap, but the lowest price I ever found was at Sears, back in the
early 1990s, for their Diehard brand, which were stocked next to the
garage door openers and only $1.25, compared to $3-5 for similar bulbs
at other stores.
