Re: CBus + CFLs



Thanks Kevin.

What would be involved in the capacitor approach for CFL's/LED's - is it
simply wiring something in before the first bulb in a series (in the case
of multiple downlights on one circuit) - and with a lamp socket is it
something that could be incorporated into the lamp cord/outlet whilst
keeping it looking neat and remaining child-safe ?

Cheers,
Greg
