CF Bulbs In Enclosures - Page 3

 

I've had ones like this on my porch for the last 5 years with no problems.
The directions listed them as OK for sealed fixtures and any mounting
direction.

I only "problem" is that in the winter, they start out dim, and take awhile
to
brighten all the way. If it's in single digits, they look like night lights
when they
come on, and take 5-10 minutes to reach full brighness.

    I know I am joining in late,  but,  I have to say I have been
running 2 of the 100 W equivalent 24 W CFL bulbs that are designed to
allow dimming in the two ceiling fans I have in my family room (where my
computers reside).  These bulbs are both hanging down (base up) in
enclosing 10" glass globes, and are generally on 12 to 18 hours a day.  
The ambient temperature varies from a maximum 82 F.  down to a minimum
of 57 F.  (I actually log this @ 5 min. internals) and these lights were
installed on 18 Aug. 2004 when I upgraded the fan controllers.

I have been very pleased with CFL in general.  These seem to stand up to
the fan vibration very well as well as the heat.  a 60 W incandescent
"FAN" bulb would typically last 40 to 50 days before breaking the
filament at best. (Appliance bulbs maybe a little longer, but they were
too dim).

By the way the CFL bulbs I have (about 30 including other Dimmable and
some 3 way socket styles) don't seem to bother my X10 stuff but I do
have large capacitors to correct my power factor on the entire house's
240 VAC input and I also am producing as much as 10 kW of 240 VAC from
my solar PV system.

One rather unusual use of one of the 3 way CFLs is in a lamp by my chair
in the family room.  It is plugged into the same 1500 VA UPS from APC as
my INOGEN ONE oxygen concentrator.   I use this as a backup for grid
power so I can still breathe when some idiot hits a power pole with out
sitting in the dark.  It will supply my oxygen and the light for almost
12 hours without any help from Pacific Gas & Electric.
