RE: Re: Can an LD11 control a 240v 50w Halogen bulb?

["Harry Hendriks" <hja_hendriks@xxxxxxxxxxx>]

I have in my house several sets of 5 * 50W/240V halogen bulbs via LW11G's
(Marmitek, Europe) working at various dim levels (controlled by PIRs and a
Homevision controller) since one year. Never had any problems with the
concept and also did not have to change any bulb.
The only problem I encountered is that the TW523 does not like to be
overloaded (too many instructions too short after eachother).
This may not solve the problem to be addressed in the subject line, but
could be of interest.
Cheers,
Harry Hendriks
