Are you suspecting low voltage? No, the whole room is on the same breaker, and my UPS shows a nice steady 118v coming in. No flickering lights, either. Should be good in this department.<br><br>My belief is that the &^%$@ ceiling fan vibration is doing them in. This would be consistent with standard bulb being worse than the "Appliance" or "Fan" varieties. And also consistent with poor mechanical support and soldering reported earlier. These fans are "Hampton Bay" models form Home depot. On sale, but should
have passed them up. The master bedroom is immediately above the Shack,
and I can't run the fan late at night if my wife goes to bed before I
do, because of all the buzzing. Exceedingly annoying in the summer.<br><br>Greg KO6TH<br><br><br><div class="gmail_quote">On Wed, Jun 1, 2011 at 3:16 AM, Rudy Benner <span dir="ltr"><<a href="mailto:rudy@ve3bdr.com">rudy@ve3bdr.com</a>></span> wrote:<br>

<div>A good start would be to go into your lighting panel and tighten down all
the connections, with the power off of course. Tape up the screwdriver when
doing the main connections.</div>

<div style="font-style: normal; display: inline; font-family: 'Calibri'; color: rgb(0, 0, 0); font-size: small; font-weight: normal; text-decoration: none;">No,
I think it's more a matter of brand/manufacturer. We've got the Computer /
Radio / Sewing room here, with two identical fan/lamp things on the
ceiling. Noisy buzzers from Home Depot (don't get me started!).
Regular incandescent lamps don't last. "Fan" or "Appliance" type lamps are
better, but still succumb to the vibration. We tried to replace the
Fan-type with some round globe-type CFLs, no-name from the local hardware store,
mostly to bring the heat down. They lasted less than the Fan ones
did. Replaced some of them with the "Curly Fries" type from GE, I think,
and they're still going strong.<br><br>So, it's not the position (all are
base-up), not the voltage (same circuit), not the ambient environment (same
room). What's left?<br><br>Greg KO6TH<br><br>p.s. Neither brand gave
me any problems with interference on HF...<br><br><br>
