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? You want to analyze them be my guest. 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. Whoa, big surprise there. Be still my trembling heart. 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. :D You just had to mention a personal spectrum analyzer. Now I'm jealous. The CFL's run hot due 'Probably' to the drive electronics being as cheap as they possibly can. Anyway I think the main source of noise is something else. I unplugged my power strip on the other side of the room and got a little less noise but still well above the Galactic noise level or the receiver's. I bought some new CDL's and replaced the really crummy ones, so it is getting better. The worst offender now is a touch lamp that uses an SCR, but even off it produces noise, again made in China. 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". |

I meant Milliwatts. |

Now the film division is going down anyway. That corporate manager might not get his Porsche. Do I feel sorry for the executive?? Hardly. |
