<font face="Courier New">When experimenting with dimmable LED bulbs
vs. LED-compatible dimmer switches it quickly became obvious that
only a few combinations worked well from full to minimal
brightness. This eventually lead me to

and then

<br>
These sources quickly stopped all the experimenting by pairing
specific dimmers with specific LED bulbs which yielded excellent
LED dimming. So far they have not been the least expensive bulbs
available but, having solved that problem, I can use my interests
and time to spend exorbitant amounts of money elsewhere.<br>
<br>
We now have 15 $3.99 STAPLES LED bulbs in frequent (non-dimming)
service with no failures so far. Nine more are still in their
boxes. (Thanks Karl!)<br>

<div> Thanks. And a question below.<br>
<br>
I had a $10 off Staples coupon so I got 3 LED bulbs for
$2. Now that I've tried them, I might go back for more, if
they have any left. Most of my house has CFL's or similar,
with incandescent in the master bedroom and master bath
for the best dimming capabilities. I counted about 90
bulbs altogether.<br>
<br>
</div>
<div> I tried these dimmable LED bulbs with dimmers, and
they are pretty good, except for the slightly high turn on
light level with triac dimmers (I assume solid state
dimmers still use triacs).<br>
</div>
<div><br>
</div>
For the past 30+ years I've been using a variac as a
dimmer in the master bedroom, to eliminate the audible
lightbulb buzzing/ringing sometimes caused by triac dimmers,
and to provide excellent light control, especially at very
low light levels.<br>
<br>
</div>
<div> Here's the question: I tried these LED bulbs on the
variac, and they dim very well, even at pretty low light
levels. Are these dimmable LED bulbs safe to use on a
variac? And are there any reasons I shouldn't use them on
the variac?<br>
