Screw in flourescent light bulbs.

Guest
I only two of them in my house.One in my kitchen and the other one in my
bathroom, I never turn them off.Just now I was in my kitchen getting me
a ''cold one''.That flourscent light bulb blipped a couple of times.What
does that suppose to mean?

Maybe a "brown-out" on the power line?

The one I leave on 24/7 usually conspires to fail when I'm out. Common
failure modes are the tube or the mains in reservoir electrolytic, typically
they start flickering or just go "phutt".

Back in 2003 I saw a 13 watt Osram CFL end its life in bursts of
sparks and smoke through a hole melted in the side of the ballast
container. I called Sylvania/Osram and they offered a replacement free
of charge. I told them no thanks I prefer to not have my home burn
down if another one of these failed while I wasn't present to
disconnect its power source. That scared me away from CFLs for a long
time.
 
I agree. Same here. I saw the big sparks and smoke. I changed back to
incandescence. I would not use it even it is free.

The only one I ever saw do that was one I'd fitted bigger transistors in an
attempt to use it as an electronic ballast in a 6' strip light - it even
worked for a few days before blowing up.

Thing is the quality has improved dramatically over the past 6 years.

However I still wont leave these on while unattended unless they are
outside as my security lighting consists of the latest 23 watt slim
socket design lamps branded Sylvania CF23EL/MINITWIST.
These tested pretty robust surviving outdoors completely enclosed

for incandescent floods out in the rain and now snow. That fixture is

as I was having some minor problems with juveniles trespassing and

MOSFETs work better but you have to increase the turns on the feedback
toroid dual secondaries to feed the higher VGSthr.

I've had one outside for a couple years now. It's only semi-protected
from direct rain, but not enclosed. Temperatures from 0F to 100F over
the seasons. Controlled by a timer, on about 6 hours a day.

If the lamp is secure in the socker and no serious brownouts, suspect
bad solder conncetions on its PCB. Eventually, it will just go out
completely. 50:50 it will blow one or both transistors, else resoldering
will probably fix it.

I used to love to experiment like that.
Some times it just "feels so good" to let the smoke out.

A few months ago, our shop was shipped some incorrect Bosch automotive
relays we use to honk the horn from the LMR radio (crew page).

The problem was that these had an internal "back EMF" snubber diode
across the coil. That would be no problem if plugged into a prewired
socket, but we wire them manually with spade lugs and often in poor
light where you couldn't see the diode polarity-to-lug markings on the
schematic molded into the black plastic . Get the coil wires
backwards... blow the switch transistors in the radio!

The fast fix was to hook up a 20A bench supply to the relay coil
terminals so the diode was forward biased and watch the current jump to
20amps for a second as the diode blew out... no longer a problem. Only
bad part was the smoke couldn't get out as the relay is sealed.
 
I think I'll stick to beds, the couch, the floor, hot tubs, etc.
I was trying to think of how to make that joke, but you beat me to it.

I converted an inspection lamp that uses an 8 watt 11" T5 tube with a
resistive ballast in the cord to electronic ballast using a new 9 watt
'off brand' CFL board. Works a treat and has seen a lot of use over the
last three years. Fitting it in required some very creative board
trimming and taking the resevoir cap and series cap between the
filaments off board.

The left over brand new CFL tube went into a good brand CFL that had
become seriously blackened at the ends and gave me a couple of years
more life from that.

I have a standard home Shop Light fixture that I shorted the ballast
out with commercial bulbs. Guess I'll tear it apart and see what
happened because when it fires it draws a lot of current for maybe a
half second then shuts down (protect circuit I suppose).

This will be a good litlle experimental repair for me never having
torn one apart to repair before.

Yeah the 23 watt Mini Twists I put out this summer have survived out
in the elements only protected by a 2" deep "half shroud" and the
depth of the lamp socket. They are angled at 45 degrees down and on
the wall of my garage on the leeward side of where our winds come from
so that helps with the moisture a bit but otherwise are completely
open to the elements.

And I was happily surprised that they survive well completely enclosed
outdoors in the heat. One out front is in a globe and is on from dusk
till dawn.

So as a conclusion to my tests I will probably migrate to these
Sylvania Mini Twist CFLs. I like the 2700K color of these and they do
put out a lot of lumens even the 13 watt version is very bright.

They idiot politicians are doing the same in the U.S., but more
slowly. I've laid in a very good supply of incandescent bulbs
already and should have a lifetime supply on hand by the time the
ban takes effect.

I have been playing with the circuits for a while and IMHO there is a
possibility of a dead short when bad spikes occur in the supply.

http://www.pavouk.org/hw/lamp/en_index.html

There are two MJE13003 connected across the supply and I suppose they
are to only alternatively. By any chance if they conduct at the same
time even for an instant you had it.

All the circuits I built had short lives when I connected to bad
supplies.

My 2 cents
