Hi,=0D
=0D
Does the fact that these LEDs and some CFLs are dimmable mean that they =0D
can be controlled by automation though? I thought one of the issues were =
=0D
that some types of timeswitrch and electronic switch power themselves by =
=0D
putting a trickle current through the incandescent load which causes =0D
problems for "modern" lighting?=0D
=0D
I've a few (non-HA) security timeswitches that I'd like to move to CFL =0D
or LED so I'd be interested in views.=0D
=0D
Thanks,=0D
