GE 15w CFL lamp, shown both before & after I tore it apart

Something went wrong with its crappy electronic electronic ballast: it made a pop & a spark could be seen down inside...after which it did nothing.

I took a dremel tool & cut it open to see what was inside LOL
one little transistor-ish-looking thing in the ballast had exploded as had a resistor

The "resistor" thing is a fuse, it did it's main job.

I see there no apparent capacitor damage, so I would guess it is a normal, designed, end of the CFL's life.

The transistors usually overheat (so pop), when the tube electrodes loose the emission coat (when the electrode is not able to support the ballast curent anymore), so the voltage drop across the lamp rise, increasingthe real power drawn from the ballast and the phase conditions the output stage of the inverter work. As aconsequence the power dissipation rises quitea lot, usually yielding a thermal breakdown.

CFL ballasts do not contain any tube EOL protection, neither is overrated to handle that, as no one expect the electroic (or any other part) would be ever used again after the tube (or anything elsethere) fail, unlikethe "big lamp" ballasts...

Personally I really like these A-shape CFLs over the spirals, what about you guys?

Well, I would not name this A-shape, it is quite far from that.
I don't mind the naked spiral, it is more efficient than covered.
And the naked spiral will run cooler, so it have better chance to be more reliable...
But I'm not fan of these integrated compromises, simply because of the necessary compromises in the design...
So having to choose from these two, I will go for the naked.

Ehh the A-shaped lamps (that is what they're sold as Medved, though you're right, they're far from the shape of an incandescent) look better but it's the same crap inside. I really don't like CFLs period and I hate that my parents use them. They do save energy though.

Personally I am a user of CFLs, although I use magnetic circline (Or, if I had any) PL adapters since the lamps are replaceable as opposed to a spiral where you just chuck the whole thing when it dies. Although I do like the electronic ones, particularly 2700K A-shape (Or other shape) ones or 5000K or 6500K of any shape.

I like PLs since they're blink happy but they're very flickery and dim and take a while to "warm up". I've never really had any experience with preheat circline though.

I USED to have an ABCO 13w PL adapter and lamp but when the lamp quit I tossed it, not knowing any better! It came with my house and the lamp was well-used.
Nowadays, a few years later...there's fluorescent lights all over my place! There's only 3 general-service incandescent lamps in use on my property and they're all in places where fluorescents or CFLs would take too long to warm up. There's a couple 3w 6400K PAR LEDs in a de-motionzed motion light (I know, you LG people hate those) and other than that and a couple nightlights and an IKEA desk lamp with a 25w hi-intesnity bulb all the lights in my house are some sort of fluorescent, be it CFLs, preheat circlines, electronic F32T8 or magnetic rapid start F40T12 fixtures! I always tell people, 'If you get migrane headaches from fluorescent lights then you will have terrible seizures in my house!'

What I use are few linear fluorescents, one circular with an adapter (electronic, 3-way dimmable) and some LED's.
The one LED made in a compact form is problematic (it overheats after about half hour and goes into thermal shut down protection mode)

Most CFLs I think, have the lamp filament fusing as EOL protection. Is the fuse here to prevent the CFL from explode in flames, should the voltage doubler operate?

I"m don't speak English well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230-240V, 50hz country.

@dor: The fuse could prevent the flames only, if all the possible failures causing high heat generation (so igniting the fire) create really high mains current, so the fuse always blows.

But if you take the standard doubler circuit ( like this ) have the input current limited by the reactance of the capacitors. So even if the output short circuits, the current can not reliably exceed the trip current of the fuse in time, mainly because the fuse manufacturing yield quite a tolerance (normally the CFL fuses require several amps to reliably trip).
But this limitation still could yield to quite severe heating - several amps from 120V mean several 100's of watts, dissipated there easily for many seconds of the internals exposed to heat.

If you take the full bridge, there is no current limitation, so few 10's of A could easily flow there, yielding fuse tripping in few ms, so even when talking about many kW power dissipation, the time is so short the total heat energy (what have to be absorbed by the mass, if it has to ignite it) remains very low, so not able to cause any big troubles.

I had one of these a few years ago..it failed early in the same way you described

I wonder if it was a design flaw in these?

The fact the electronic blows at the tube EOL isn't that much a design flaw in integrated ballast CFL's, as the whole thing would go to thrash (or recycling shop) anyway.
However essentially the same design is sold as the ballast only for mostly all fluorescent types and there it is a design flaw - one should expect the ballast survives many lamps and does not dies with the first one...

Yeah this is a disposable unit (which I'm so strongly against, though if the lamp and ballast were separable, the replacement lamps would probably end up being the same cost as a new integrated unit).

But what is more important: Being so tightly cramped together, the electronic life is not much longer than the tube, so with a lot of extra costs (ballast protection, some socket system, dealing with the extra size the socket would occupy,...) it would be success for the ballast to go through the second lamp's life.
So beside the replacement lamp would cost the same as the complete CFL today, even the cost of the first purchase would be way higher.

But still there were few attempts for replaceable tube concept, however I haven seen selling the replacement tubes for that...
