I have a couple of them where the ballast failed like that..
It can't be too bad because the PSC still has not issued any bulletins on the subject..

The story mentions using CFL in pot lights.. 
I have used the standard spiral CFL in recessed lights for a few years now.. is that against what the design of the lamp is meant for?

I've seen a few like that when they were used with dimmers.

1.)Don't buy cheap lamps
2.)Read the label (enclosed fixture rated, maybe)

The biggest problem is that every house al the switches are on dimmers,
and people just buy the cheapest lamps without any thought at all..

I'm really surprised that it's not a requirement of the lamp listing that they fail safely when used on dimmers....

They are more expensive and not every CFL application is dimmed. Go to Danvers, it'll be fun.

What is PSC?
I've seen tantalum chip capacitors burn like that on circuit boards. Maybe the ballast uses these types of caps.

A lot of things can be produced and be supposedly proven to be safe by the "Underwriting" authority, however it is the final user who will get the results. The CFLs that do not have a glass envelope are so fragile that they, in a lot of instances, develop a slight crack at the base and future problems occur, Those of us who are used to just turning/screwing the bulb into the socket may not realize that. The fracture WILL occur.

A few years ago tantalum was mostly a waste metal from platinum and rhodium recovery. I wonder if the use in cfl s (if it is used) is contributing to the recent salvage value.

I'm liking the new halogen energy savers. A 43 watt is equal to 60 watt output, and a 72 watt is equal to 100. I've never been a fan of CFL's. I'll stick to incandescents as long as possible.

It is hard to kick old habits and I am one of those, but with information about what "light" is most like you are used to, you can find a CFL that will suit you. I would not have thought that but it is so. Do not buy the "brilliant ones. Buy the ones that are enclosed with a glass envelope and say "Soft white".

People who come by never even notice that my lighting is CLF. It's the same color temperature and almost the same CRI, and these are bulbs that I got off the shelf at Target.
I think in most applications incandescents are an antiquated technology.
Once they work the kinks out for CFLs in low and high temperature applications, I would expect the incandescent to disappear.

I bought a dimmable CCFL from Globe about a month ago. Died last week with black rings where the tube meets the mount. It's on the way back. After the last early death from Globe I started keeping my receipts. Lightbulbs shouldn't need a warranty.

Wait till next year then try to buy a cheap 100w rough service incandescent. You won't find them. Just like the old mogul base 3 way, gone to never never land. They have to stop making them.
