I know this is an older thread, but after conversations with Jeff, I'm trying to revive it.
I have been running for a few years with 6 CFL "bug bulbs" in my outdoor fixtures. They are a mixture of n:vision and EcoSmart 14w (60w equivalent).
The 6 fixtures are controlled by two SmartHome Insteon ToggleLinc relays, and two Insteon SwitchLinc relays.
(For those of you having trouble with the math: two switches have two bulbs each, the other two have one bulb each)
Other than one bulb going bad prematurely (I think it was one of the n:vision ones), and throwing out enough noise to cripple my entire system, I haven't had any other problems with them.
I just replaced 11 more bulbs. I put in 6 of the Philips "EnergySaver" 13w (60w equivalent) in one fixture, and and 5 of the 9w (40w equivalent) in another.
Each fixture is controlled by a SmartHome Insteon ToggleLink relay switch.
I didn't detect any issues with either fixture, and with both of them on (6 of the 23w ones, 5 of the 9w ones), I didn't have any problems with the rest of my system responding to commands.
I don't have an XTBM (yet), so I don't have a way to measure the noise levels of these bulbs.
I also bought a few of the Dimmable EcoSmart 65w equivalent spot bulbs for my recessed lights, but I found the "Daylight" version to be too bright, so I didn't get to the point of testing for noise.
I have to exchange those for the "soft white" version and test again.
Can anyone recommend a recessed spot bulb (r30 type) that is a soft-white 65w equivalent, is dimmable, and doesn't interfere with X10?
(I have two older SmartHome Togglelinc dimmers on those lights, and I'd rather not change the switches out for relay ones if I don't have to.)
