<p>Hi all,<br>
<br>
My entire house is kitted out with C-Bus leading edge dimmers, with a
<br>
mixture of MR16 low voltage and GU10 mains voltage lamps, amongst other
<br=
>
things.<br>
<br>
This setup has been working extremely well for over 12 years, however
<br>
due to the phasing out of halogen lamps I am now looking at my
options.<br>
<br>
So far as I can tell, leading edge dimmers are not great with dimmable
<br>
LEDs, and trailing edge would be better.  However, I don&#39;t fancy
<br>
swapping out a bunch of rather expensive C-Bus dimmers that are <br>
otherwise in perfect working order.<br>
<br>
So... what are my options?<br>
<br>
How are the rest of you handling the move to LED? Any recommendations
<br>
for brands to try?<br>
<br>
.......or are we all just going to stock up on halogens while we
can!<br>
<br>
(which to be honest wouldn&#39;t take that many bulbs, as due to
someone&#3=
9;s <br>
advice on here, I run all my dimmer channels at 95% load which <br>
dramatically extends the life of the lamps)<br>
<br>
Thanks,<br>
<br>
John<br>
