CFLs the Reveal-ing Truth [RFI]
Recently bought a 2-Pack of GE Reveal CFL Light Bulbs at Walmart
that were rated at 100 Watt 'replacement' and uses only 26 Watts. CFL = Compact Fluorescent Light GE Reveal CFLs are Made in China Ok so on the back of the package GE 'reveals' "This product complies with Part 18 of the FCC Rules, but [B-U-T] may cause interference [RFI] to radios, televisions, wireless telephones, and remote controls. * Avoid placing this product [CFL] near these devices. * Do not install this product [CFL] near maritime safety equipment or critical navigation or communication equipment operating between 0.45-30 MHz." and now you know ~ RHF |

The newer CFLs I have purchased appear to be radio-silent, at least at HF freqs. Still want LEDs, tho... |

For what it is worth. I went into the local Walmart and found generic Chinese bulbs at $.99 and the identical bulbs labeled as GE or some other American name brand at twice or even 5 times the price so all you are getting is the American name and making the CEO a lot of money. I'll bet they laugh all the way to the bank. |

I'll bet they laugh all the way to the bank. Well, you may be right...or you may be wrong. You know these bulbs are -identical- how? You've seen the specs for both brands, you've done a comparative chemical analysis of the gas and the phosphor coating inside the bulbs, right? Oh, what's that you say? They both -look- like CFLs so they must be identical? As an aside, got a friend that bought both the Chinese junkers and GE. He claimed the warranty support for GE was great and non-existent for the Chinese. Finally, as to RFI... I've got two GE 3-way CFLs (50-100-150 watt equivalent) very near my stereo receiver. There is subtle (but noticeable) RFI when the receiver on and listening to the FM band. Yes, you would think FM is immune to any amplitude modulated interference, but the RFI IS there and goes away when the CFLs are turned off. Also, bringing a Sony 2010 near the bulbs shows some mild RFI on some frequencies, not all across the bands. If I wasn't so lazy, I would break out the HP spectrum analyzer and take a look. P.S. Just in case you mistakenly think I am defending GE CEOs, I believe that Neutron Jack Welch should have been put in jail long ago, rather than being feted as a "business hero". |

Fire Starter Flashlight You can make your own fire starter/starting flashlight too.A few years ago, Popular Science magazine had an article how to do it, check your local library.I don't know if it will cut metal though.It will make steel wool blaze up. cuhulin |
