CFL's
Locked

I had this same experience in a living room lamp...I feel that we came
close to having a fire because the lamp socket was too hot to touch...The white
base of the bulb is not ceramic, it is plastic and is hollow, containing a
number of electronic components...In my case, the white base was cooked to a
light brown, was cracked, and it collapsed when I tried to unscrew it...The
PCB inside was burned to a crisp...This bulb bore the name and logo of a
bed-rock American company and was made in China...It would seem that the
hype selling these bulbs to rhe public should include a warning
about allowing the bulb, which runs relatively cool, to be too close to
flammable objects, such as lampshades...

I heard a burst of static behind me. That was odd since no radios were on. The only thing on at the radio desk was the desk lamp and a power supply that keeps the batteries charged. Both are plugged into a strip that switches power to them. I went over to the radio desk and looked at my equipment, both off. Still puzzled I turned on the 2m rig, all normal. Then I turned on the K3. All normal. I turned them off again. The K1 sits by, not connected to anything at this time. Still puzzled I sat there wondering if something had happened to my battery bank or one of the batteries. I have three 26AH batteries in parallel. Each battery is fused before to goes to a fused buss. Then my nose began to notice the smell we all dread. Something electrical was over heated. Still I did not noticed a symptom I should have noticed earlier, the desk lamp was off. I touched the top of the lamp and it was very hot. The bulb, a 13 Watt Florissant had failed. The ceramic base was too hot to touch. How often do Florissant bulbs fail this way? I had the feeling that if I were not there a fire may have started. 73, Ty, W1TF, K3 #696, K1 #1423 _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Not just California John, the entire nation...They've
got a BIG push on to sell these screwy looking spirals here in NY...They do save
energy, but they are also dangerous and they don't want us to know that...I
reported it to the local fire marshall and he came and picked up the rest of my
bulbs for testing...That was a year ago and is the last I heard of it...These
bulbs contain mercury and it is illigal to dispose of them in the regular trash,
you have to take them to a hazardous materials disposal center...

I am the one that started this thread, altho the subject line has changed. It is wonderful to have OT subjects that all can learn from.
Thanks to all that responed. I have learned much and now have even more concerns about CFLs. On the the next step, Where can I buy (or build) an LED desk lamp that I can pulg into a spare APP (Anderson Power Pole) connection on my Rig Runner. That will complete my emergency power setup.

If you want to have the use of any 110v lamp:
I gave up on trying to buy all the special and separate chargers and everything for 12 volt. What I do now, and it works for "everything", is to use a power inverter in the car, truck, and on the bench for a "few" small things. When you get your cell phone, HT, laptop, or whatever, you get a 110v volt recharging device. With the inverter, you are set. One of the inverters I have is probably about 15 years old and has been mobile most of the time (and looks it), kicked around, abused (physically) and it still works great (hard to tell what color it WAS). When I go mobile to an event in radio support, I usually take an additional battery and use it separate from the vehicle to run the radios until it needs recharging and then jump them together (through a long 18 ga wire to add some resistance during the initial recharging to limit recharge current and protect the wiring) and start the car . Another plus is that you can take a REAL 110v trouble light instead of a flashlight. If you want to put a lamp on the desk, get an inverter and use ANY 110v lamp (but put in a more sensible bulb than 100w) remembering your power usage is now multiplied by ~10. 100w on 110 volts ~1 amp, 100w on 12 volts ~10 amps from the battery. Just get a 15w bulb or so. Yes there is "some" power loss in the inverter but it is minimal compared to the load, just be reasonable with the load. That's it IMHO, de Jim KG0KP ----- Original Message ----- From: "Ralph Tyrrell" <[hidden email]> To: <[hidden email]> Sent: Monday, October 06, 2008 10:12 AM Subject: Re: [Elecraft] CFL's > I am the one that started this thread, altho the subject line has changed.
