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? cuhulin |

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. "Meat Plow" wrote in message ... On Mon, 1 Dec 2008 17:53:16 -0000, "ian field" wrote: wrote in message ...

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. |

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. |

I used to love to experiment like that. MOSFETs work better but you have to increase the turns on the feedback toroid dual secondaries to feed the higher VGSthr. |

Thing is the quality has improved dramatically over the past 6 years. Especially with the push to outlaw incandescent. 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 in a globe as porch lights and in a security light fixture designed for incandescent floods out in the rain and now snow. That fixture is a motion detector but it was frequently placed in the manual on mode as I was having some minor problems with juveniles trespassing and wanting to use our trampoline.

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. -- sam | Sci.Electronics.Repair FAQ: http://www.repairfaq.org/ Repair | Main Table of Contents: http://www.repairfaq.org/REPAIR/ +Lasers | Sam's Laser FAQ: http://www.repairfaq.org/sam/lasersam.htm | Mirror Sites: http://www.repairfaq.org/REPAIR/F_mirror.html Important: Anything sent to the email address in the message header above is ignored unless my full name AND either lasers or electronics is included in the subject line.

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. -- sam | Sci.Electronics.Repair FAQ: http://www.repairfaq.org/ Repair | Main Table of Contents: http://www.repairfaq.org/REPAIR/ +Lasers | Sam's Laser FAQ: http://www.repairfaq.org/sam/lasersam.htm | Mirror Sites: http://www.repairfaq.org/REPAIR/F_mirror.html Important: Anything sent to the email address in the message header above is ignored unless my full name AND either lasers or electronics is included in the subject line.

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 used to love to experiment like that. 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 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 -- Thanks for your time Ardent |

Your lucky in Australia they are in the process of banning incandescent lamps we wont be able to buy them There will come a day in the USA when you will not be able to purchase incandescent lamps. I think it's already in law. There is a need for instant on lamps for safety. It can take a few minutes for my outside lamps to come on, and I'll miss the burgular. I'm switching on 6 CFL's for my porches and driveway. greg |

They exist. I've had them in my condo for some time. They come on instantly -- faster than an incandescent -- at roughly half brightness. It takes another 30 to 60 seconds to reach full brightness. |

When she got to Sammy, whose father ran a local toy store, she said, "Sammy, since you're Jewish, I guess your family didn't celebrate Christmas." Sammy replied, "Oh yes, we did. We all held hands and danced around the cash register singing, 'What A Friend We Have In Jesus.' |

A hell of a lot more often than with incandescent lamps. A lot of
incandescent fixtures are not designed for safe operation of CFLs. It would be more-correct to say that the CFL is not appropriate for the fixture. Some CFLs, I believe, are marked as not being suitable for "upside-down" installation, because in this position they'll overheat if there isn't sufficient circulation. |

Its been a long time since I've heard of cheap imported novelty light fittings being set alight by the heat from a "bulb" either. The last time I changed the hall light (to fit a CFL) the brass bayonet ring fell out of the socket because the bakelite had become brittle with age and heat - I leave the hall light on when I'm in except when I go to bed. There was no evidence that it might be a fire risk. |

In a trial, a Southern small-town prosecuting attorney called his first witness, a grand motherly, elderly woman to the stand. He approached her and asked, "Mrs. Jones, do you know me?" She responded, "Why, yes, I do know you, Mr. Williams. I've known you since you were a young boy, and frankly, you've been a big disappointment to me. You lie, you cheat on your wife, and you manipulate people and talk about them behind their backs. You think you're a big shot when you haven't the brains to realize you never will amount to anything more than a two-bit paper pusher Yes, I know you." The lawyer was stunned! Not knowing what else to do, he pointed across the room and asked, "Mrs. Jones, do you know the defence attorney?" She again replied, "Why, yes, I do. I've known Mr. Bradley since he was a youngster, too. He's lazy, bigoted, and he has a drinking problem. He can't build a normal relationship with anyone and his law practice is one of the worst in the entire state. Not to mention he cheated on his wife with three different women. One of them was your wife. Yes, I know him." The defense attorney almost died. The judge asked both counselors to approach the bench and, in a very quiet voice, said, "If either of you idiots asks her if she knows me, I'll send you to the electric chair." |
